We try to meet you preference but this is NOT GUARANTEED

We will try though to accommodate your choice but don’t shout at us if a certain style or colour has gone please. If the colour and style is important to you please consider ordering the ones you require, we’re the cheapest available for IKO shingles anywhere so regardless of the free offer ones or bought you won’t find a better deal with any other supplier. 97% of the time we can meet your preference except when stocks are very low.

UPDATE:  Shingle Glue

Although there is a bitumen strip on the tiles and that they should also be nailed in at least three places on a strip we are recommending (due to our dodgy weather recently) that you consider also applying Felt Shingle Glue along the leading edge when sited in exposed areas. This is also necessary with low pitched roofs.

UPDATE: Membrane

IKO are now recommending a membrane under layer is also applied. As a company we do not think this is necessary on garden buildings and nor does other garden building companies. However if you wish for a underlay membrane please see of roofing felt page for standard felt or IKO recommended membrane. If you are using a membrane we would recommend the standard felt over the IKO membrane but the choice is yours. Please note for lower pitched roofs and flat roof a membrane is recommended by us as is shingles glue.

UPDATE: Modern Log Cabins

As of the 5/2/2021, we have stopped offering free offer shingles on our Modern Log Cabins. These changes will also apply to the orders placed after the 5th of February.
To ensure our customers receive the best roofing option possible- We have now changed the options for the Modern Log Cabins. Now, pricing for the Modern log cabins include EPDM Roofing and Adhesive which is the best and most reliable roofing option we can offer, This is what we always recommend for log cabins with a pent style roof.

The EPDM is supplied with adhesive and is a superior alternative compared to normal roofing felt and shingles for cabins with this roof type, lasting for up to 20 years.

Or you may prefer to use your own roofing option? Not a problem as you can select to purchase this cabin without any roofing atall at a reduced rate under the options tab.

When shingles are available:

When shingles are free and available they can be selected from this drop down menu on the product page.

If you want to buy alternative shingles or they are not available:

If we do not have the free ones you require or they are not available please order them from here.

Do you need Roof shingles on your Log Cabin?

Do you need FREE ones? In my opinion the answer is always yes!

When I was first involved within this industry about fifteen years ago log cabins also emerged as a popular alternative to the humble shed or summerhouse. Back then it was unthinkable to sell them without shingles.  As well as the style of the buildings the shingles set them far apart from a common shed which of course a log cabin is not.  Then, about five years ago some bright spark realised that if they sold the cabin with felt they could undercut everyone else making them look the best value for money.

So, now you will find everyone sells cabins with felt as everyone had to follow as customers look immediately at the head line price when zipping through the internet or a brochure.  Roof shingles then became an option across all retailers, which is a real shame as I think all Log Cabins need roof shingles to become anything other than a crappy shed.

You’re buying a building that will last forever if cared for, surely you want a roof material that will do the same?

As an example, here’s a shed roof with felt:

Shed felt roof - Horrible isn't it!

Shed felt roof – Horrible isn’t it!

This is what is supplied as standard with all log cabins these days.  It’s ordinary shed felt and as such it doesn’t look nice at all.  Try applying this to a pyramid roof or a roof over 3m in length, it’s horrible and impossible to make it look nice, more than likely you’ll end up ripping it as well, you’ll see the roofing nails and anything more than about 3m you’ll end up with ripples and bubbles in it.

This is a picture of shingled roof a customer proudly sent us:

It looks so much better, it turns a ‘Shed’ in to a proper garden building.  It also lasts for years, no nails can be seen, no ripples and no rips and of course you won’t have to do it again in a couple of years time.

Here’s a few pictures of my own log cabin, it sits directly under trees and has taken years of abuse, I’ve never cleaned the roof or carried out any maintenance (as I wonder what will happen eventually) and it’s still as water tight as it’s ever been

Here’s another view of the poor thing:

An old log cabin shingled roof

This building is very old now as you can see but the tiles are still going strong.  An ordinary felt roof would need replacing after about two – three years, less if it had trees over it like my old log cabin.

Standard Roof Shingles

Within our catalogue and drop down lists on all the cabins we have shingles that can be selected in a variety of colours, most of which can be available in straight, hexagonal or curved style.  you can also see our roofing materials in the category:  Roofing for Log Cabins.  These are all manufactured by a company called IKO who enjoy world renowned success and unrivalled quality, you really can’t get better than these, if you watch the movies you’ll see them on all the American houses as they love their felt shingles.

Roofing options

I’ve hated the fact that we sell buildings with ordinary felt, in fact a colleague tells me “she shudders” when a customer buys a log cabin without them, to tell you the truth I do as well as felt really does spoil what should be a stunning building.

It also saddens me when a customer calls up and asks for shingles saying: “they should have ordered them with the building“, which, they should have and we try to encourage them to but some customers think we’re trying to up-sell and refuse at the time of order.

It’s then upsetting for them and us when we can’t offer them at the price on the web page as those prices are calculated taking the standard felt away and no delivery charges as they are priced to go with the cabin.  When we then have to charge them higher prices due to delivery and no removal of the felt costs they get a bit miffed and disappointed.

Normal prices of felt shingles can be seen in the roofing category.  It’s not good for either of us to be disappointed so please think about shingles with your order, we’re not up-selling we’re making an honest recommendation.

Now the good bit …..

FREE Offer Roof Shingles

I’m going to go back to the old days of log cabins and offer FREE shingles with all our log cabins AND the prices of the buildings aren’t going to go up either unless the Euro exchange rate forces us to or a promotion ends.  The point is our FREE offer shingles aren’t going to impact on the prices.

Tuin is pretty big and we have come up with a solution so we don’t have to send you the dreaded standard roofing felt. All our old stock, last years colours, shingles in damaged packaging etc are all sitting around and aren’t sell-able as a brand new product.  Normally we will sell these in bulk to shed manufacturing companies when they ask for them. Instead of selling these to the trade we’re going to keep them and are now offering them FREE with all our log cabins and shed manufacturers are going to be a little peeved with us.

There is a tiny catch though

I really do wish we could get back to the old days of a log cabin inclusive of shingles and you simply choose a colour.  But, the shingles are expensive things, an average log cabin is 18 sq.m  a packet of shingles covers 3 m.sq.  That’s an average of 6 packs of shingles with an average cost of about £180.  Some people don’t want to pay the extra £180 on a building and who can blame them if they are happy with roofing felt (uuurrrgh)

So, we’re going to give you the Offer shingles FREE on all the log cabins but the catch is we get to choose what style (straight, curved or Hexagonal) and what colour we send to you without charging you for them.  This is because we don’t know what we have / will have of the offer shingles at any one time until we allocate them to an order.

I hope you don’t mind?  There’s got to be a trade off and you’re getting the shingles for free.  Of course after placing an order we will email you the colour we are sending and if you don’t like it you can opt for the standard roofing felt.

Alternatively you can choose a colour and style of your choice from this season ranges using the drop down menu on each of the log cabin product pages so you know exactly what you’re getting.  You’ll find all our shingle prices better than any competitor anyway!


I don’t know of any supplier / manufacturer / retailer who can even get close to this offer. Have you found anyone who can offer shingles at our prices, even the standard ones? Let alone FREE shingles! OK, after a search I did find one supplier but the price of the cabins are far too expensive to worry us about.

Old days of Log Cabins

Well, we’re almost back to the old days.  At least now we can sell cabins with shingles again and still be the most highly competitive supplier there is in the UK.

Please understand though we may not be able to keep this up all the time so we do reserve the right to stop the offer when stocks are depleted and this will generally be without much notice at all so please don’t shout at us if you suddenly see the offer has been withdrawn on the log cabin you have been thinking about for a little while.

Before you ask, we’re really sorry but when it ends it ends and we can’t offer them retrospectively.  This is much like all our offers.  We are honest and always will be if it’s offered please take it.  When it’s gone it’s gone.

Ongoing Log Cabin Maintenance

Hello and welcome to what we hope will be a useful guide towards the ongoing Log Cabin maintenance.. yes it may come as a surprise to some but just like a lot things in this world, log cabins do need to be given some attention every now and then to ensure they operate as intended.

As much as we would love to provide you with a completely self contained product that requires zero maintenance it simply isn’t possible with this sort of building.

Please expect to have to perform the odd bit of aftercare.

Firstly lets just have a brief recap on how our log cabins are made so we can all get in the right frame of mind, by now you may have already installed your log cabin which means you will of already read our comprehensive online Installation manual, Or perhaps you’re still in the planning phase.. Either way we would suggest viewing the above to gain more clarity and perspective on the whole project.

Before I started working here, When I thought about “log cabins” I would immediately cast my mind to the wooden buildings seen in films made from round tree logs sitting in a snowy forest somewhere nice and peaceful.

Snowy Log Cabin

Yes Please

Who wouldn’t want to buy one of these right!.. although you may need to make some life adjustments or sell a kidney to stump up the funds for this sort of project.

Our Log cabins are made a little differently and we like to think more financially and garden friedly, they consist of flat solid wall logs in a range of different thicknesses, stacked ontop of one another which then interlock in the corners with Wind and Weather Proof Connections.

TUIN Log Thicknesses

28mm – 70mm Log cabin logs

These wall logs will in most cases rest on what we call Foundation Beams to bring them up and off your base, These foundation beams as a minimum will be pressure treated for longevity.

After the walls are up you then turn your attention to the roof, These come in different styles and sizes of course but the principle around them is the same. You start with the purlins/rafters then the roof boards are fitted on top to create the solid wooden surface to fix your roof covering to.

Then low and behold!.. you have yourself a whole new building ready to be used for whatever you can imagine. looking for Inspiration?

Easy Right… for some more information about fitting out buildings please also visit our Fitting Tips page.

So there we have it, thats the building up and ready to use but how do you keep it looking and performing as it should and what other considerations should you be thinking about to keep it a fully functional, problem free living space.

Perhaps the best way to go through some of the key points will be to break the cabin down into six areas .

  • The Base for the cabin
  • The Foundation beams
  • The Walls of the cabin
  • The Doors and windows
  • The Roof
  • Additional hardware and extras


The base is the first thing that gets laid and is critical for both the longevity of your building and its actual construction, i’m not here to talk about what base you should or shouldn’t use as all these details can be found with in our Base Support page already and in reality theres very little you should ever need to do to maintain it which is lucky as it becomes very inaccessible with a lump of a log cabin sitting on top.

However something to look out for would be subsidence, Let’s say you have a concrete slab, or a compact base with slabs on top.. with the weight of the cabin on top has it sunk it some places?.. hopefully not but its worth keeping that in mind to check if you find yourself with a misbehaving building.

Or perhaps you have built the cabin ontop of a raised Timber Platform and under the weight of the building one or more of the corners have sunk throwing out the top level like this unlucky customers did.

A sinking timber base

See the gap?.. Customers timber base had sunk in the middle

Luckily for this customer the timber base was fairly accessible from underneath so he was able to add additional support to bring it back level

Another important aspect of a base is damp proofing, using a Damp Proof Course ( DPC for short ) or a Damp Proof Membrane ( DPM ).

A DPC is generally used underneath your foundation beams, its purpose is to protect the underside of your foundations from rising moisture seeping up through your base as well as providing protection against ingress from the outside.

There are other ways to achieve the same level of protection, My favorite is to use a TAR product, painted on both the underside of the foundation beams and on top of the base that they sit on.. applying this thickly will also service in sealing the perimeter helping prevent ingress.

A DPM is used underneath the concrete slab or ontop of it, This will again protect the underside of the cabin/floor from moisture that tries to rise up from and through your base into the building.

Advice on using a Damp proof course in your base.

Advice on damp proofing

Ideas for Damp proofing

Preventing this moisture from rising up within the building is very important, it can cause unwanted growth with in the building as well as other Unwanted Issues.


Mold with in a cabin

Nasty right!

Ventilation does play a big part in preventing this as well which we will cover in a moment but if you notice that a once dry and mold free cabin starts to experience these types of problems then a review of your damp proofing may just be in order.

Foundation Beams

Now these are also very important and often in truth the cause of great confusion at first with our more traditional shed building customers.

So just quickly, Unlike a shed where you would expect to see a row of bearers all running the same direction with a floor built directly on top..

A normal Shed is built on top of a floor with joists underneath it

Typical shed base

A typical shed with bearers running the same way

The Foundation Beams service a different purpose for this type of building. they only span under the perimeter of the cabin (as well as any internal walls that might be featured).. What they DO NOT do is span in the middle where the floor goes later on.

Their purpose is to raise the first logs off and away from the base which in turn protects them and provides added room in the middle for a floating floor

We have different types of foundation beams to offer but they all serve the same purpose and will generally sit on top of your base with a DPC in between. This will generally be enough to keep unwanted ingress from entering your cabin but where two foundations beams butt join together you should think about enhancing these connections with a decent sealant/sealer.

Walls Of the cabin


Well here we go, We are starting to get into this now as once the walls are up you can finally start to get a good feel for your log cabin, as we mentioned before the walls are made from individual logs stacked ontop of one another to from a very solid wall, They interlock in the corners with fancy Wind and Weather Proof Connections which go along way to ensure that your cabin remains water tight… But as we also explain this isn’t where the story ends and you cannot just leave the logs as as they are and expect the building to be watertight which leads us swiftly onto a very important part of maintaining your log cabin which is TREATMENT

So let’s start by asking a question.. What is Wood?

Wood is basically a Sponge and this is how you must treat each individual part of your cabin, if you zoom right into the endgrain you will see that it’s made from straws all joined together which was once used to draw water and nutrients to the parts of the poor tree that once needed it.

Wood is a sponge and is made up of straws all drawing water for the tree.

Close up of timber

Wood is a sponge and is made up of straws all drawing water for the tree

You can easily see from these pictures that when we look closely, wood is full of holes and it’s these little buggers that will be causing a problem as they all fill with water or, drain of water as seeing as we killed the poor thing there is no tension of water to rely on.

For an untreated piece of wood especially this is happening constantly, it’s trying to reach the same moisture content as the surrounding air. This is known a Relative Humidity and is a measurement of the amount of moisture in the air around us.

In the summer the wood will expel moisture and shrink, In the winter they will absorb moisture and swell which will loosen and tighten the joints where the logs interlock.


A lot of customers will fairly just assume that “treatment” is only applied to safeguard the wood, stop it from rotting ect but in truth this is just one of its benefits. Treatment is also there to try and limit this natural movement as much as possible , We want to limit the amount those sponges can absorb and expel moisture by clogging up the straws contained with in.. we do this by reaching the recommended depth of microns.

A decent treatment should provide the following benefits

  • Protect the surface from weathering (including UV damage)
  • Seal wood on wood joints with in the cabins construction
  • Reach the required micon depth ( 80-120 microns ) which helps limit natural movement
  • Provide the desired finish for appearance

More information on Timber Treatment specifically can be found within the other support articles we offer

I hope the above all makes sense as it then leads on to the ongoing maintenance of your cabins walls. They must be treated and they must be treated well, please do not expect to only have to treat your building once throughout its life time and Please Please Please use a decent treatment in the first place.. To many times have we had angry customers over the phone shouting, screaming at how dreadful it all is and how disappointed they have become….to only find that they hadn’t applied enough coats, hadn’t kept up with the re-treatments or instead used a lets say “less expensive” brand in the first place.

We recommend our own Tuin Treatments or specific ones found locally such as Sikkens, Sadolins and Kingfisher which we know work well at achieving the desired depth of penetration.

You will not cut the movement out entirely which is fine because the building is designed to handle a certain amount without any fuss.

So as the logs of the cabin move ( which they will ) you may then need to re-treat certain areas of your walls, Paying particular attention to the end grain and interlocking notches where they join another wall, these are the most vulnerable parts. You will also need to make note and follow the manufacturer’s guidelines in terms of reapplying dates.

Overgrowth around the cabin.

This part is mainly aimed towards landscaping and storage rather than the cabin itself.

I’ll start by repeating one of our bold statements that we confidently make about the properties of timber, .. Wood will never Rot … we promise… Well, we also go onto say that so long as it is always ventilated, . so if it gets wet and is then allowed to dry it will be fine.

but what if it can’t dry?, What if air can never reach some parts of your cabin due to overgrowth, shrubbery, stacked rocks, Muck ect…

What if you decide to store things right up against the side of the cabins wall such as logs for a burner and leave them there for a few years while they season..

All of a sudden the wood will not be able to breath, vent and dry, Water could then sit there all winter which will eventually cause you all sorts of grief

Please be mindful of your walls, Make sure they are free from direct contact with anything which could cause a water trap, keep on top of your gardening in those hard to reach areas as if you allow overgrowth to take over it can really ruin your day… you may even decide to call us.. complaining about the timber quality in the first place… “sorry but its wood” we will tell you.. “it only rots if its not allowed to vent” we will try and explain… you won’t like that.

Movement In log cabins

As we know by now the walls of the cabin move as the logs Expand and Contract throughout the seasons, the design allows for that just fine.

But what if you want to fix something to the wall like a mounted TV bracket or some shelving to store those garden tools.. I always tell people they can do whatever they like to these types of buildings so long as they follow the golden rule which is.. “You must always allow for vertical movement with in the logs” further explained with in our Dealing with Expansion and Contraction page

Another consideration for some, if your cabin happens to feature vertical posts that supports a canopy or large overhang you will need to periodically check that the adjustable post anchor that we supplied is set at the right height to match the rest of the cabin.

So let’s say you happen to own a building like our Kennet log Cabin

Kennet Log cabin

Our 28mm Kennet Log cabin

Remembering that the wall logs expand and contract, that front post will need to be adjusted from time to time as the seasons change because it will not move to the same extent, This is achieved by simply adjusting the nut that sits beneath the smaller plate on the anchor.

Doors and windows

I think the best way to approach this section will be to start by gently reminding you that just like the walls, The doors and windows are predominantly made from wood, you remember all of those straws?.. Sponges.. yup this wood is no different

Sure,..the doors and windows tend to be made from timbers which are laminated together which does improve their strength and reduces the possibility of movement but its still wood and it still has those straws.


The correct treatment of the wall logs is very important.. but I would personally say that the correct treatment of the doors and windows is even more so and here’s why

Unlike the logs, The doors and windows do not have the same luxury of being fully and always supported.. The wall logs are locked in place and would do well to move in any unexpected sense.. but the same cannot be said for the swinging doors and windows… they are only connected to the cabin via hinges which means if the level of treatment isn’t correct or sufficient you may eventually encounter unwanted warps or twists to occur making them much harder to operate.

When first delivered the doors and windows normally arrive deep with in the pallet, This is on purpose as it provides needed support and compression while in an untreated state to prevent warps and twists… but at the very least the pallets are always banded tightly.

Doors packed within a log cabin package to protect them especially from warping

How our doors and windows come packed

Doors packaged with in the log cabin package to provide compression, preventing movement

You then unpack the doors and windows, Please store them flat and again under compression until ready for installation and treatment. While in situ you need to be very attentive with your treatment and often customers will not give them the attention they sorely require. Treatment should be applied both sides evenly and heavily.. To many times we have had customers upset because their doors have warped and to find out after that they didn’t treat it fully or correctly..

An extremely warped door.

A twisted/bowed door

A very twisted door, Do we think this was stored correctly prior to installation?


Luckily, even the most twisted door can be corrected with the simple application of a Turn Button or Key,.. you would have already seen these in action in gardens throughout your life time i’m sure as we explain within our other Support Page so don’t panic too much but like most things prevention is better than a cure.

Please keep on top of your door and window treatment.

Let’s move onto those hinges that we mentioned earlier, The doors and windows will come with their own style of hinges so you can operate and use them.. A lot of the time they are cup hinges that look similar to this

Two piece hinge forming a cup and spiggot. These can adjust the door in both planes.

Hinges commonly found on our buildings

Typical Cup Hinges

Now remembering what we discussed before, while treatment will limit the amount those pesky straws can absorb and expel moisture.. it will not cut it out entirely. You will at some point need to adjust the hinges of your doors and windows so please expect to do so, We go into more detail about this with in our other Support Page

A lot of the windows we send are top hung which operate from the inside via a simple Window Stay, we have all seen them and they do the job nicely

Its always easier to pre-treat the windows and doors before they are fitted so you can be sure of full coverage but sometimes this isn’t always possible. or perhaps it’s just time to recoat them following the manufacturer’s guidelines.

Top Hung Window

Common type of top hung window on our Emma Log cabin

If you find yourself having to unhang this type of window from the cabin please be aware of an important Safety point before you proceed. The hinges are only designed to keep the window in place with in the constraints of the supplied window stay which means if you lift it up further, the hanging part which contains the glass could slide off. Be ready to take the weight and seek help from another if needed.

Window Stay Limitations

Be careful when lifting the window beyond the stay limitations

While on the subject of door/window furniture, let’s also talk briefly about the actual locking parts, The cylinder, mechanism, latches ect

These are pretty much self contained but some considerations should be made such as occasionally adding some lubricant with in the metal workings so everything operates as it should.. you don’t want the metal parts seizing up.. also consider oiling the exposed elements to keep rust and corrosion at bay.

Also think about fitting a traditional hook and eye’s for your doors so that during use you can keep them securely open, what we don’t want is the wind catching your new doors and smashing them against the walls… thats how things break which nobody wants.

Hook and Eyes

Hook and Eyes being used on our Chloe log cabin


That’s about it for the actual hardware, but what about the glass that lets in that sought after natural lighting.. what do we possibly need to consider in terms of maintenance.

The panes of glass are dry fitted into a rebate contained with in the door or window, this is all done prior to delivery as it’s much safer to transport while in place.

The panes of glass can always be accessed if ever needed, they’re only held in by wooden beading which can be Removed With ease as we show with in our Glass Support Article

How the glass is held in place

Glass held in place with removable wooden beading

There’s a few things that we need to think about and one of them which is often not really considered is the seal between the glass and that wooden beading.. is it sufficient?

Going back to treatment by this point you will have fully treated both sides of your window or door right up to the glass.. This alone will typically be enough to prevent water from encroaching between the two surfaces and finding a way into the cabin.

You may also ask yourself, Surely they will come pre-sealed in some way right.. why wouldn’t they be…..?!

Well actually no, they do not. The glass is just dry fitted inside the rebate of frame… thats not because we couldn’t be bothered or we’re just trying to save a few pennies on some silicone here in the office to keep the accountants off our backs. It is dry fitted for good reasons!

Firstly, While the packing team do their best to pack the pallets in the safest way possible, we are talking about several tons of a log cabin being moved around and transported over huge distances by several hauliers so things can happen and your glass could arrive damaged ( rare but possible ) .. its glass.. it can break!

For those of you that have used silicone before you will know that it can act abit like glue at times.. so in the unlikely event that you receive your cabin and some of the glass is broken its then an absolute nightmare and down right dangerous to go around and dislodge the broken shards from the inner frame and in the past when units were delivered pre-sealed we received right ear falls from angry customers and rightly so.

Hopefully you agree and can see why we do not send them out pre-sealed, So once you have treated the frames in full and you then go on to notice ingress, all you need to do is either run some sealant along where the glass meets the exterior beading… or if you want you can remove the beading and silicone where the glass directly fits into the inner rebate instead.

Refitting the glass is the reverse of taking it out. If you wished to you could add a bead of silicone sealant although this is not necessary.

Sealant being used

Silicone being added with in the rebate

Movement in log cabins

Moving on slightly, Let’s think about how the frames actually fit into the walls of the cabin for a moment

Back to Movement again ( sorry ) The door and window frames are made with dry, fixing free U-channels which slot over the wall logs which means they will not constrict anything as it moves.

The U-channels are formed by what we call fascia boards… some call them architraves.. they’re basically just planks of wood screwed to the frame to create the U shape. These cover up the all important expansion and contraction gaps which are left above and to the sides of the frames ( please do not in-fill these gaps with anything )

Log cabin doors and window installation

Fascia boards fixed to the perimeter of the frame to create a U-Channel


So a few things we need to consider in terms of ongoing log cabin maintenance,

Have the inner sides of the fascias been treated correctly, fully? ..Well they should be as they also play a good part of sealing the outer perimeter of the frames.

Have you accidently sent fixings through these fascias which then also penetrate the moving wall logs underneath?.. if so please remove them as you will be preventing those logs from moving with the rest and you will most likely end up with gaps in between those logs.

Or, Perhaps you have noticed gaps around the door frame but are pretty adamant that there are no fouling fixings.. Try loosening the fascias and then re-tightening them.. if that doesn’t work then send us some pictures so we can have a look with you.

Maybe you have treated the underside of these fascias but you have noticed some signs of ingress? In this situation we may just need to enhance the seal between the two wooden surfaces.. Removing the fascias and adding silicone or draft excluders will normally cut that right out .. Just let us know and we are happy to send you some FOC.

Log cabin Extras

We can provide an array of Log Cabin Extras to complement your log cabin and their requirement depends mostly on the circumstance

Before we touched upon the importance of Ventilation which helps prevent moisture from building up within the sealed cabin, If you are not constantly in and out of your building should consider adding Air Vents to allow a continuous flow of air in and out of the building.

Also think about what you store within the cabin, White goods especially kick out a lot of moisture so be sure to install vents to combat that.

We also offer Storm kits as an extra, These are spring loaded metal rods which are used to ensure that the roof of the cabin remains tied down to the rest underneath, most applicable to those in very exposed areas or for those cabins with large exposed canopy/overhangs… please consider the application of a Storm kit

Shingle Glue is an option to consider, Very handy again for customers in exposed areas but generally if you are installing in the winter it is suggested to safeguard the shingles until you summer next rolls around.

We highly recommend Guttering for your log cabin, Not only will this help filter roof water to the desired location it will also serves in protecting the walls and perimeter further down from unwanted ingress and splash around the base.

We also sell a product which is very useful for coating the inside of the walls, Its called Impregnation Fluid on the website and is a very powerful Anti-rot, insecticidal treatment which you could consider, Please note that in inside of your doors and windows will need more than just this product alone.

Log Cabin Roof Maintenance

The roofs on these cabins should really be pretty self contained, so long as the roofing material was installed correctly there isn’t really that much you should ever need to think about.

Just keep an eye on any unwanted growth ontop, Moss can sometimes start to build up which should be removed as and when you can. Overgrowth can prevent the surface from ever drying out fully… also if you happen to install the cabin in the winter and moss manages to build up before the summer comes back around it could limit the amount of heat that gets to the tiles which is needed to bound all the those bitumen strips together.

Build up of moss

Serious overgrowth, Overdue a clear out we think

It will also be a good idea to periodically check underneath the roofs fascias for any nests which long term could start damaging the wood.

before those fascias are even applied they should be pre-treated as they are hard to reach once installed, Just like the other parts of the cabin you will need to revisit the treatment after a set timeframe and these higher parts are easily forgotten about and missed.

We hope this helps and we are happy to answer any unanswered queries that may come to mind, Please also revisit our installation manual for much much more.


  • Keep half a mind for your Log Cabin Base, Check the levels if you start to notice anything strange happening with the cabin on top
  • If you start to experience high levels of condensation within the building consider checking your damp proofing and joints between the foundation beams.
  • Remember that wood is a sponge, Keep on top of your treatment and please use something decent., Recoat those vulnerable areas and meet the guidelines set out on the tin.
  • Treat the doors and windows well and frequently
  • Fit hook and eyes to your doors to prevent unwanted wind damage
  • Keep your green fingers busy, Stop overgrowth from taking over and allow air to fully circulate around the cabin.
  • Do not create water traps around the walls of the cabin
  • Be mindful when fixing anything to the walls, Remembering your cabin likes to move
  • If you find water ingressing around the glass, they need sealing further
  • Guttering should always be fitted to better protect your cabin
  • Add Air Vents to prevent the build up of moisture
  • Consider the need for other log cabin extras
  • keep half an eye on your roof, remove overgrowth frequently


Log Cabin Roof Strength

Sometimes we find our selves at a bit of a disadvantage selling log cabins in the UK, the main reason being standards, we have them but don’t really need them here!

UK Standards in Log Cabins

In the UK there are no building regulations for garden buildings, there’s not even guidance. The UK can make anything they want and shed manufacturers do. Same with summerhouses greenhouses and of course the same with log cabins – especially when they are ‘Made in England’ or for the UK market and designed for it’s crazy planning regulations.

Basically a manufacturer can produce anything they want to, and they do.

Europe Standards for Log Cabins

The trouble we have when competing in the UK is Tuindeco sell across Europe.

To do this they have to meet certain standards and not just make ‘anything’ they feel like to a price point.

For instance:

  • Germany, it is required by law, that there has to be a snow loading capability of 120 kg/m.sq,
  • Austria and Switzerland it has to be 90 kg/m.sq.
  • Spain and Greece are substantially lower of course but there are still standards and a lot more so now the Euro-Codes are being adopted more and more.

Costs of a good Log Cabin Roof

Trouble is, when selling in the UK we then have the costs of this strength when compared to UK companies manufacturing whatever they fancy with no regulations or standards to follow. This can sometimes see our prices being slightly higher on some buildings. It can also raise a complaint such as this which I saw mentioned in one of our reviews on our site:

“I would happily foregone the extra 9 cm in height that would have reduced the cabin apex 2.5m height and therefore ‘legal’ as regards planning aspects especially within boundaries to borders of less than two metres.”

And this is part of the problem we have, you’ll look at the price, the height, but have you thought of the strength you are getting? Will it last over the years without a sag developing?

A sagging roof can develop over time due to a miscalculation of loadings or cheap manufacture.

Weight applied to a Log Cabin Roof

Lets, for a moment, pretend we do have standards to meet in the UK. Lets look at a building and what we are designing to:

Forces acting on a roof of a log cabin

Forces acting on a roof of a log cabin are the same as any other structure – Dead Loads and Live Loads.

The input loads will be made up of the following:

  • Dead Loads – This is the loading of the weight of the roof itself, the roof boards, purlins / rafters and what the roof is designed for as the final roof covering such as felt or shingles, tiles, sedums etc.
  • Live Loads – This is the weight applied to the roof from external factors such as snow, rain, wind loading and of course maintenance – such as people working on the roof to install it and maintain it.

The Output of these loads needs to be transferred to the supporting rafters and purlins, the wall logs and ultimately to the load bearing element which of course is your base and then finally to the earth it is sitting on. We have to make sure the structure is capable of carrying and transferring these forces safely and securely. Of course we also have to make sure that the building will carry on doing this for years and years.

The roof needs to be designed correctly for the loads placed upon it. This will be reflected in the ridge height, strength and number of purlins and thickness of the roof boards.

The roof needs to be designed correctly for the loads placed upon it. This will be reflected in the ridge height, strength and number of purlins and thickness of the roof boards.

Snow Loadings in Log Cabins

This was an interesting picture from 2010 when the whole bloomin’ country was covered in the stuff!

Snow in the Uk, the whole of the country was covered at one point

Snow in the UK, the whole of the country was covered at one point

It might well have been this that made Scotland adopt the Structural Euro Codes in 2010 and that England is following suit now along with the rest of Europe and several other countries such as Russia, Algeria, China etc.

When we design a roof we’re looking at the strength of the timber used, in our case Northern Spruce. We then look at the angles and compare that with the intended roof covering which is always shingles. Lower than 10 degrees WILL result in failure at some point of the shingles, you may not find it for a year or two but they WILL fail, really watch out for low pitch roofs with shingles, you will need to use under-roof membranes and a lot of glue to make sure they seal. They will not be doing any good on their own.

Angles play a huge part, for instance for every 10cm we can go higher in the roof pitch we can get an extra 5 kg in supportive weight. This makes a massive difference when calculating the strength of a roof on a log cabin.

When we have a ridge height of 2.59cm in the example above there is a reason for it. To reduce the height lower it then would not be strong enough for the snow loading calculations we work to or enough of a pitch for roof shingles to be effective.

Weight of snow

In the past in the UK we haven’t really been worried about the stuff but it does seem to be getting worse in the UK. Here’s an interesting map:

A map showing the snow loading requirements in the UK

A map showing the snow loading requirements in the UK

This map is showing the required snow loading calculations that should be met for a residential property in the UK. You’ll notice the maximum is 80 kg/m.sq and thank goodness Tuindeco cabins far exceed these and I don’t have to worry about a complaint in a few years time!

December 2010 was exceptional in the UK’s snowfall, at one point 60cm fell over night and on a lot of roofs 50cm was sat on top.

Fresh fluffy snow is about one tenth of the density of liquid water. One litre is 1000th of a cubic meter. One litre weighs 1kg. This means that 10mm of snow is equal to 1mm of water.

Therefore if we look at our 50cm on the roof the loading is 1m.sq x 500mm deep / 10 = 50kg

So, overnight you have 50kg sat on top of each 1m.sq of your roof.

As snow settles it will change form several times depending on temperature and time so the weight of the snow on the roof can become heavier due to compacting ice crystals.

You can see from this why the UK has a snow loading requirement of 60 kg/m.sq and higher in some parts.

As I’ve mentioned, for garden buildings in the UK there are no standards at all, we can make what we want, out of whatever we want and it’s great for you if it’s to a price point. It may be a bit of a problem down the line though if we carry on having heavy snow falls.

Also it’s worth asking your insurance company if a garden building is covered for structural damage caused by snow loading. I bet it isn’t!

A Log Cabin Roof Costs

Lets go backwards, let’s pretend you’ve found our buildings or even another supplier but the price just doesn’t match up to the REALLY competitive price. Then let’s pretend we do not have standards to meet and we’ve got to match it, here’s some figures for you to consider:

  • Every 10cm / m.sq higher cost us at the factory £7.50 (ex VAT)
  • OSB is 80% cheaper than Tongue and groove Spruce.
  • Pine is cheaper than Spruce
  • 16mm – 12mm is cheaper than 18mm
  • Cutting a purlin in half is 50% cheaper.

If Tuindeco were not constrained by standards in Europe but made solely for the UK everything could be so much cheaper. There’s a lot of cheap cabins out there, trouble is they’re not as cheap for the consumer as they should be bearing in mind where the costs are cut.

Log Cabin Roof Strength Calculations

All the good manufacturers list a calculation for the strength of the roof, Bertsch, Lugarde, Scan Holz, Tuindeco. They do this for a reason and it’s an important one that you may not have considered when you are buying a log cabin.

I would recommend, regardless who you are buying from that you ask them what specification they build to. The UK standards for building construction asks for a minimum of 60 kg/m.sq and 80 kg/m.sq in some parts of the UK. Your log cabin should at least comply to this.

Tuindeco design cabins with a snow loading of 110 to 140 kg/m.sq and this makes for a very strong roof indeed. This calculation is reflected in the ridge heights, strength and number or purlins and the thickness of the roof boards that are used.

Your log cabin should be designed to at least the UK snow load building requirements. Ask your supplier what the snow loading specification is and ask for a reassurance that your roof will not sag  – Ever and regardless of ‘Extreme’ weather conditions!

‘Extreme weather conditions’ is the excuse that will be given when sags start to develop as is ‘Out of Warranty’. This should not be the case in your log cabin or indeed any garden building if it was designed correctly in the first place.

Extreme snow loading perhaps but it is something to consider!

Extreme snow loading perhaps but it is something to consider!

 Installation of a Log Cabin

As well as the loading calculations you’ve also got to be able to get on the roof and install the building, you’ll also need to do maintenance on it over time. All log cabin roofs should be designed for this. Specifically ask your supplier if this is part of the design intent for your log cabin.

There are a lot of cabin roofs out there that you really wouldn’t dare to get on and I’ve known fitters refuse to shingle roofs because of it.

Make sure there is a design intent that allows you to walk on the roof for installation and maintenance

Log Cabin Carpenters or Builders

Log Cabins are pretty easy to install as long as you know the basic fundamentals.

The problems come if you don’t understand the build and sometimes worse still; if you employ a ‘professional’ to do the build for you who does not understand the process.

Sometimes beware of the professional as they may lack the understanding fully of what is involved despite their credentials of a professional builder, carpenter or joiner.

Please note most professional Tradesmen are absolutely fine and competent, this post is aimed at some that you employ that maybe too confident in their own abilities and may not understand the build, or, in some cases will not find out the complexities believing it to be a simple shed.

Professional Trades People

I’ve said it before, anyone who is a qualified builder / carpenter / joiner or ‘time served’ or ‘experienced’ or ‘trusted’ does not necessarily know about how to install a log cabin.

I think sometimes it is down to their professionalism and that they believe they should know it all but there are some key points that should be understood. Sometimes though this may not be fully realised by your chosen, (non log cabin experienced) installer

In a previous post (Here) I recounted the story of a customer who was recommended as follows:

“A friend of mine who has been a ‘time served chippy’ for 40 years told me that all I had to do was nail a board over the gap.”

Just because your chosen installer is a ‘professional’ it does not mean they know what they are doing with a log cabin install so please thoroughly check with them and make sure you ask them to read and understand our advice: Log Cabin Installation Advice.  

We also list a great deal more advice here: this advice may also be pertinant to other reputable suppliers, regardless whether you buy from us or not. All these things are useful to know if you are considering a Log Cabin from most reputable retailers.

Please remember though; “installing a log cabin is easy” – I say this all the time: Log Cabin Fitting Tips. BUT to make it easy you need to understand some basic things about the install and have a proper understanding of the building.

Below are examples of some very silly mistakes made by tradesmen who didn’t understand a log cabin install. All of these customers came to us rather fraught and we had to guide them or the installer on how to do it correctly, in some cases we had to visit site and correct the build, in the extreme it needed a complete new building.

Log Cabin Floor

A log cabin floor should go inside the cabin, not the cabin on top of the floor!


The floor needs to be a floating floor as you would in your house.

Our log cabins have a floating floor inside the cabin and it is installed after the cabin has been built.

Our log cabins have a floating floor inside the cabin and it is installed after the cabin has been built.

Never allow your installer to lay the floor first and then the cabin, this will cause you lot of problems in the future. The floor should be a floating floor and your builder should be aware of this. Some ‘professionals’ treat a log cabin as a shed, a log cabin is a completely different beast to simple sheds.

Log Cabin Base

We explain the importance of a base for your log cabin and this must be passed on and understood by your chosen builder.


This base is hugely out of level and the installer is trying to make good by blocking it up

He ignored the foundation beams supplied and installed the first log directly onto the base .... why?

As well as trying to block in he hasn’t used the foundation beams and the bottom log is in constant contact with the base. This is really not good!

If you are going to chock up the mistake in the base then at least use a treated timber to do this. These pieces will rot over the next 12 months and then everything will drop badly with huge problems to the building.

For smaller gradients you can use timber shims to take up a small gradient but do not use untreated wood as these will rot very quickly and the building will drop

This builder is using unstable blocks to chock the base level and is also using untreated timber.


As well as unsuitable blocks the builder has also laid the floor first and the cabin on top.


Unsuitable blocking of a timber frame base


Untreated timber being used as shims will very quickly rot.


A block directly on to grass with untreated wood is not acceptable.

Please also watch the base your builder puts down when using concrete, a wriggly and unlevel base is not a good thing for a log cabin.


This is a very bad base for a log cabin, rough concrete is never very good. Notice also how unlevel it is and one side needed to be chocked. This poor lady had a few problems with water ingress and very unlevel doors

This was a terrible install by a professional builder. The base was hugely out and to compensate for the building lean he cut the lower logs to match and then added some sort of filler! In the end this complete building had to be replaced.


This base was terrible so the builder cut the logs to make the windows level in the hope the customer would not notice.

A very bad base causing the whole building to lean. This builder then cut the logs to make the windows straight!

A very bad base causing the whole building to lean. This builder then cut the logs to make the windows straight!

Log Cabin Walls

I will warn you as I have done in other posts, professional builders, joiners and carpenters may do this if they do not understand the intricacies of a log cabin …. they fix the doors or windows to the wall logs. For some reason they may forget the idea that wood expands and contracts especially when unsupported by a frame.

Gap appearing in a log cabin wall

Gap appearing in a log cabin wall

You may have seen this picture in other posts of mine and this is one that sticks with me, I use this example over and again as it was so costly for the customer. She was a Doctor and I knew exactly what the problem was when she sent me a series of pictures. The fitter had attached the window and door frame to the logs.

There then followed a dialogue about how experienced they were, she had used her personal carpenter of twenty years and her stone mason to install, she also had a professional painter to treat the building.

We agreed that if it was our fault we would replace or repair, if it was the builders then they would pay for our time. Our service guy was onsite for two minutes and fixed it by removing screws and the whole log cabin dropped happily.

Unfortunately it did cost her. The professional carpenter of twenty years standing who had been watching very quickly went away when everything settled into place.

This is THE biggest mistake made by a ‘professional’ who does not understand a log cabin or timber expansion or contraction. I find this with builders, as they are used to fixing frames in houses they will do it to a log cabin – please check for this.

Log Cabin Roof Shingles

Sometimes I will look at customers pictures of a complaint or a help request and I really can’t believe them. This was a ‘professional experienced builders’ roofing install:


Look at it closely, ALL the shingles are upside down!

Every tile, unfortunately, is installed upside down.


Another experienced roofer cocks it up – notice how the ridge times are done!


This is another favourite ‘experienced roofer / builder / Carpenter / Joiner mistake. No correct spacing and each shape should form a true hexagonal, these were all dropped down too much and massively effects the design intent and aesthetics, not to mention you run out.

Watch out for the above, if someone does not know what they are doing or does not follow the instructions, spacing of the tiles will start to go horribly wrong and you will run out of shingles.

We have some good videos that show how best to install shingles, instructions are also on each pack of shingles.


Another example of a ‘professional’ install. Please show inexperienced fitters the instructions and videos before hand. Not all builders or Carpenters understand what to do.

Upside Down Log Cabin

This builder was just not at all on the ball and made a very silly mistake. He asked me why the top log would not go on. I replied ….. ‘because you have built it upside down’!


Upside down log cabin, please look at the instruction advice and check the plans, the tongues always go up. You do not want to have your builder make it upside down and then have to take it down and install the correct way up.

 Botching a Log Cabin

I see this a few times each year, something has gone horribly wrong with a build and then it’s bodged to hide up the mistake. This was a particularly bad one and one I did not enjoy helping to solve as it was so far gone.


This one wasn’t very fair. The builder had not read the plans or parts properly.

The installer did not read the plans and measure all the parts, he added them as he thought fit and then realised it was not going together. Instead of taking the roof apart and correcting before nailing on the roof boards he carried on with the build.  This produced all sorts of problems.  He then had to hide up silly mistakes with bits of wood in various gaps with pieces of trims and blocks. It was quite a mess at the end and not a lot we could do for the poor customer.

This was a bad building recently. The customer was lovely and they had chosen a Bergren Carport and Garage. A great building but one that does takes some knowledge to install, a bit of skill and time. It’s one of our hardest to install though and should not be taken on lightly.

Sadly the builder made a bit of a mess of it rushing through the install and not really considering what he was doing or taking into account the basic fundamentals of timber, a log cabin base or the effect of the environment around it.

He later admitted he was not prepared for it.

Unfortunately the install went very badly and we were asked to correct it for them. This meant a total disassemble and reassemble correctly on a level base and joints correctly aligned and made.

This is the finished building:


Berggren log cabin carport and garage.

These pictures are some examples of where it had gone horribly wrong, the builder had not made any joint correct and then started filling the bodges. He should have stopped and analysed the build before going any further.


As the bottom logs were so out of true this transposed to huge problems at the top. The builder then used filler to try to hide the ever increasing problems the higher the cabin went.





Every single part of this install was bad and so much went wrong. Most of it stemmed from a poor base and incorrect fitting at the start of the install. The builder should have stopped and done some basic checks:

  • Base level across the whole build.
  • Logs made correctly.
  • Joints made correctly and tightly.
  • Levels correct.
  • Completely square.
  • Measurements correct.
  • Check for errors in manufacture or errors in fitting low down.

At the end though all was correct and the customer was very happy after we corrected the install. We did though have to replace several logs that had been damaged by the builder.

It should not though happened if the builder had taken some simple advice from us, stopped and looked at what he was doing and checked the above.


The completed log cabin and a happy customer.

A Professional Builder Summary

Like any tradesman you can get some good and bad people but I always advise customers to make sure they pass on our online advice here:  Log Cabin Instructional Advice and to make sure the chosen installer has read it regardless of their skills and profession, there might be some things in there that they hadn’t considered and it will make the install quicker and cheaper and less likely to be a problem in time to come. It maybe an idea to ask them to confirm they have read our advice before starting the build.

I also highly recommend that if you are using a builder, carpenter or joiner who may not be fully experienced or you may not be sure of with a log cabin install to familiarise yourself with the advice. If anything is going wrong you will very quickly realise it and can stop the build before it goes too far.

Please though, at any point if you or your installer have any questions please let us know and we’ll be pleased to help before things go wrong. Send us a picture or what you are seeing via email, a quick description and we can advise, even out of normal working hours.

Log Cabin Contraction

This post follows on from Mr Currie’s comments on my previous post about Contraction in Log Cabins

Mr Currie commented on my post:

“I installed a log cabin from another company in 2008 and within 6 months a gap appeared between the logs next to the door frame, which I now think might be due to a design flaw. The optional front veranda is not integral to the log cabin – the ‘veranda kit’ supplied solid battens to attach it directly to the bottom six logs on each side of the cabin using screws. This is in effect attaching several of the bottom logs together, and I guess that this probably restricted the ability of the logs to expand and contract with the ones above them. I’m now wondering if I detach the battens whether the gap might disappear as the wood ‘settles back into place’.”

I very often help people via my blog who have bought elsewhere and have run into problems with their Log Cabin for whatever reasons. Normally it’s the ‘run out of guarantee’ ploy or just a lack of knowledge from the retailer that brings all sorts of people to the blogs and I really do enjoy helping where I can.

You’ll find Mr C’s and my conversation carried on in comments and we then went to emails, several were exchanged as well as pictures. Here’s a selection in case you are having the same problem

Log Cabin Contraction Problem

This was the problem:


A gap appeared after 6 months with a log cabin Mr C bought in 2008 (Not From Us), he’s lived with it ever since.


He had identified after reading my blogs that the above really shouldn’t be done as the screws in this cover plate show that all the logs are being restricted. From previous articles you will have seen why this is a NO NO.

Mr Currie thought this maybe what’s causing the gap at the top of the doors and certainly while this is not good or a correct way to install the cabin in the first place.  This isn’t though the culprit for the gaps by his door.

I do occasionally have a moan about “qualified carpenters and joiners” building log cabins which makes me shudder when customers mention this when a problem occurs.

The previous advice Mr C had received made me chuckle and also makes me shudder, yes I see and hear this sort of thing all of the time – Beware the qualified Carpenter!

“A friend of mine who has been a ‘time served chippy’ for 40 years told me that all I had to do was nail a board over the gap. It’s amazing how people who have worked with wood for so long can have such a total misconception about it’s properties and how it behaves in a structure like a log cabin. I’m sure that’s a familiar story to you :-)”

Assessment Based on the Log Cabin pictures received

I sent Mr C my assessment of the problem as below, this may also help you if you have a similar problem with your log cabin:

Dear Mr Currie,

Thank you for these pictures and description. It made me chuckle you mentioning a time served carpenter!

Professional Carpenters, Joiners and worse still Builders are the scourge of my job, whenever I have a problem with a customer it is always when one of these groups of people have had something to do with it!

Looking at your building I think you can fix this quite easily.

Depending on what you have treated it with will make a difference to how much it expands and contracts. During the first year though we see this the most as the wood is still alive, in effect the straws that make up the timber is still wide open and is sucking in and blowing out moisture meaning it expands and contracts sometimes quite wildly.

A good treatment and wood dieing a little more over the first year or two will see this reduce, it does still happen though.

This is what happened in your first year. The moisture content has dropped, the straws have now closed up more and over the years she’s reached a level. I would imagine this does close up a bit over the Autumn and winter though when moisture returns to the wood from the surrounding moist air?

To solve this please remove the fascia on the inside of the door. I bet the top log is touching the top of the door frame.

Check under the door frame for any chocks, also check to see if they put the floor under the frame, this often happens and lifts the frame. Sometimes when we’re installing in the winter months a new cabin we do have to chock the door slightly as the gap is too large. Please let me know what you find.

Please also check the top of the window, there maybe an expansion gap issue there as well?

Regarding your veranda, it really shouldn’t be screwed together like that, your solution will work provided the screws are not done up too tight, you could also make something like the attached which will hold the logs without any fixings, you may need to move the veranda forward slightly.

Best regards, Richard.

Mr C’s Reply following my Assessment

I have to be honest that I have never actually noticed if the gap closes up much over winter, mainly because it has been used as storage but is now being converted over to a workshop. It has not had much treatment to be honest, it had two coats of Cuprinol after it was built and another coat of the same last year.
I removed the top left and right part of the fascia on the inside of the door, and you were right about the top log touching the top of the door frame. When I removed the bottom part of the fascia there was an almighty cracking sound, and now the door frame is a little looser. I think that the bottom part of the fascia was resting on the floor…
Anyway, I’ve attached some photos of the door with the inside fascia totally removed. Interestingly I can’t get the bottom part of the fascia back on now – as you can see the door frame must have dropped by a few millimeters when I took it off


You will notice the the wall logs have contracted and are sitting directly on top of the door frame

Here you can see the gap at the top, the logs cannot concertina down any more than they have, hence why a gap if forming.

Here you can see the gap at the top, the logs cannot concertina down any more than they have, hence why a gap if forming.


The bottom door fascia was actually holding the whole front of the cabin up as the door frame has now dropped and cannot be fitted again. The Fascia does seem to be rather wide.

Solving the Log Cabin Problem

Having seen these pictures and following emails my advice to Mr C was:

I’m pleased to see this is as expected, the bottom fascia looks to be rather deep and will have been holding the cabin up.
At this point, if possible I would not plane the door frame as this may weaken the frame, plus you will have to contend with the screws. I would take the door frame completely out, this will then let the cabin settle down and the gaps should close up either side.
If you have a jigsaw for ease or a handsaw if you are feeling strong I would then take a notch out of the top log. I’ve attached a picture that shows a top log with a notch. I think about 10mm would be enough above the door frame. This will then give the log room to contract further in the height of summer. This time of the year though she will be very slightly bigger than she was in August.
The bottom of the door fascia does look big, you will also need to trim this down.
Doing this and putting the door back in with the fascia should solve this problem for you.

Contraction and Expansion

The problem Mr C had isn’t really one of design as this can sometimes happen no matter the design of the log cabin, this picture shows a notched log above the door which is done on some models we do if the calculations and size of the door requires it.  This is the picture I sent to Mr C as a suggested solution.

Notched log cabin log above the door to allow for contraction

Notched log cabin log above the door to allow for contraction

I recommended that this was done with his log cabin as this will allow it to contract unhindered.

The gap above the door and windows is necessary and can be adjusted if necessary.

If you are experiencing a gap appearing in your log cabin I hope this has helped and you know what to look for, if not please let me know and I will try to help.

Here are some more articles where we look at expansion and contraction in Log Cabins

When fitting Log Cabin doors – No matter how good a fitter you are, with the most perfect eye you will always need to adjust the door frame during the install, especially if it is a double set of doors. This will need to be done to have a 100% perfect fit.

It may also need to be done over the life of a log cabin due to seasonal variations in moisture content, direct sun, direct weather, all of which will affect the cabin. Of course as I talk about in previous posts, treatment makes a huge difference to this and how susceptible the doors or windows are to these changes.

Door Frame Adjustment

Several factors need to be considered for a perfect door set up, these are:

  • Square of door frame.
  • Tightness of door frame.
  • Level of door frame.
  • Door leaf adjustment to frame.
  • Door leaf adjustment to center.
  • Door leaf bow or warp.

The square of the frame is of obvious importance and this can be done in a number of ways. Personally I always make up my frame on the ground first and use a square in all the corners. I will always screw my frame and sometimes I may also consider glueing and screwing for a stronger fit over the lifetime of the building (check the frame is correct before glueing).

I have known some installers that do not screw or nail the frame at all, I do not recommend this!

With a double door the level of the frame will make a big difference to how the doors work together and if this is out slightly, it will be very evident when looking at the top of the doors where they meet in the middle.

A good example of a door frame with a slightly unlevel base

A good example of a door frame with a slightly unlevel base

Look at the above picture and you will see the two leafs do not match each other at the top and the bottom. This is because the base rail that is supporting the frame is a few mm out of 100% level. You may think the base is perfectly level but the doors will always show an error.

This is easily resolved in this case by putting a 2 – 3mm shim under the left hand side of the door threshold between the foundation beam and threshold, the two leafs will then be level.

If you are certain the door frame is fitted tightly and is 100% square (glue or screws or both, or even nail although I prefer to screw every time). If you are also certain the door threshold is 100% level and adjustment is still necessary then this can be done on the hinges.

Log Cabin Hinges

Several types of hinges are used in log cabins, all of which will allow you to make adjustment to the door.

surface mounted hinge - generally used on thinner log, log cabins. These can be adjusted on both planes.

Some people have asked me about security with these hinges, they perceive the screws on the outside to be a security risk. When I have installed these and a customer has asked, I simply use a large metal drill and take out the slots of the screws rendering them impossible to remove. You can of course use security screws available from most DIY shops.

Three piece hinge. Two parts are screwed into the frame with one part into the door, they are connected together by means of a pin. Both planes can be adjusted. These are used on heavier doors for more strength.

Butt hinge, these can adjust the doors in one plane - up and down and will mainly be used with smooth door connection frames as moving the door leaves closer can be accomplished from the frame itself. An adjustment screw can be found in the top cap of the hinge and is adjusted with an allen key.

Other hinges also exist but they will all feature a similar mechanism of adjustment, the three part hinge tends to be the most popular.

Log Cabin Hinge Adjustment

The three part hinge for some reason confuses some fitters and is also the most commonly used, please see some examples of it’s use and adjustment below:

Three part hinges are held together with a pin.

Three part hinges are held together with a pin.

This hinge can move the door leafs closer or further away from the door frame. It can also move the door leafs themselves closer and further away from each other at the door center.

The pin can be removed using a drift, or, in our case a small philips screwdriver. There is always some resistance and a hammer will generally be needed to tap the pin out.

The hinges themselves can then be turned in and out, to either move the door leafs closer / further away from each other (door leaf part), of course the doors can be moved closer / further away from the door frame adjusting the two parts on the door frames.

The hinge part can be adjusted using a thin screwdriver

The hinge part can be adjusted using a thin screwdriver, this is the door leaf part the moves the door leaves closer or further apart at the center.

Personally I like to firstly ascertain which direction I need the door to go in and then only turn the hinge parts a maximum of three turns either in or out, I will then do the same with the other hinges. Using only three turns keeps it simple and consistent.

Don’t be tempted to carry out adjustments in both planes at the same time as it can get confusing.

The pins can be loosely put back in to test your adjustments before knocking them back in fully.

The hinge pins can be left loose while you carry out the adjustment of the hinges

Once all adjustments have been made and you are happy, then knock the pins back in fully.

When you are satisfied with the adjustment then knock the hinges fully back in.

There are different types of hinges on the different models, on some we send hinges that require an alan key to make adjustments.

Alan Key Adjustments

Using the above hinges adjustments, the threshold 100% level and the frame square all door issues are easily resolved in regard to fitting perfectly.


Very rarely you may have another problem to deal with which is almost 99.9% caused by storage. A warp or bow in the door!

A warp or bow is Never a problem and it is easy to overcome or avoid.

Warp in a Log Cabin door

As well as normal adjustments to the hinges when installing, and over the life of the building you may also have to contend with a warp in the door itself. This is unusual but can happen and it’s normally caused by storage or the weather and a rather undesirable feature of wood itself – it moves when allowed to.

Doors and windows in a log cabin are probably the most expensive and complicated part of the whole building and the supplier will go to great lengths to protect these parts. Unless the building is very large or complicated the doors and windows will come within the main log cabin package and normally buried under logs.

Doors packed within a log cabin package to protect them especially from warping

Doors packed within a log cabin package to protect them especially from warping parts

Doors and windows are often protected within the package to avoid damage to the glass, but mainly to prevent warping and bowing. All timber when  supported will maintain its shape. As soon as it is unsupported it can be susceptible to movement. As well as support a supplier will also build safeguards into the door itself such as the choice of direction of timber grain and more recently laminating timber to reduce warps.

I’ve said before in other posts how an installer can greatly influence the build on how they store the parts once they are unpacked. We can cause all sorts of problems with the storage of logs and purlins, in my log cabin installation advice post I talk about storing logs flat and top of each other.

Never store logs like this in your build as you will create many warps and bows.

Only store logs on top of each other and flat to avoid the creation of warps and bows.

Like other timber products, how we store the timber will make a huge difference to the install. I show more examples of bad storage in one of my gazebo installation advice posts.

An example of how not to store parts of your log cabin. NEVER lean them up against a wall and always keep them flat.

This is what happens to parts when leant against a wall or not on a flat and level surface. Imagine the same thing happening to your door or windows.

This is an extreme example of what happens to a door when left up against a wall for several days before being installed:

An extremely warped door.

An extremely warped door. This has happened due to storage and care. Easily fixable but very avoidable with the correct storage.

A warp or bow is never a problem though and can easily be fixed but it is better not to have the issue in the first place so consider:

  • Keeping the doors and windows supported as they were in the pallet.
  • Store them 100% flat and on top of each other.
  • Never lean them against a wall while building your log cabin.

In a previous life I used to make sheds and summerhouses. After every door was made we would stack them on top of each other with spacers in between and finally we would put bricks on top of them to stop them from warping, until they were put into a building, when they were then supported by hinges, frame, locks and of course gravity, being supported level, upright and square. You should also consider the doors and windows when waiting to install them.

It’s not a problem though if you have this problem or created this!

If I’ve cocked up and made a warp in my install or even if the door moves over the install which it may do on rare occasions.

The heat from the sun can play havoc with a log cabin door or window. I talk about moisture content, cracks and warps in another post which you may be interested in and also explains what you are seeing and why: Cracks and Splits in Timber I also talk about moisture content in log cabins.

The solution is easy though, one of these ……

An ideal solution to a warp or bow in your door, I call them turn buttons but they are also referred as a thumb button

These are handy little things and available from all DIY shops, we’ll send you one or two free if you need them and these clever things will always remove a warp or bow over a month or two of application. As I’ve said above with careful consideration and handling you rarely need them, but they are a solution when you need to overcome a warp.

I’m asked occasionally how you fit them, here’s an example, I’ve oversized the pictures for demonstration purposes but you will get the gist.

If you have a double door and have fitted a door stop trim then use a similar size piece of timber that matches it. Parts from the pallet or off cut roof or floor boards is generally ideal for this.

As when working with all wood and screws we will always send through a pilot hole before sending through a screw to stop splits happening in the timber we are working on.

We've oversized here to show you but we are fixing an equivalent sized plate to the door on the opposite side and fixing to the opposite leaf.

With the plate fitted the turn button is then fixed. This can then be turned to secure the door. This works on a double and single door. The turn button is made for precisely this task.

From my picture bank I sadly like to keep, this was my worst warped door from an install I did:

With a turn button this was fixed very quickly and I never heard from my customer again.

Should you have a similar problem with one of your Tuin Log Cabins please do not keep it to yourself, we can help you to solve this easily and will send you out one of these buttons to help you.

Please be aware though that timber is a bugger, and can also do this over the life time, a huge amount comes down to the level and quality of treatment you use on the doors and windows. Without good treatment you can expect this to happen with any building, no matter the supplier. Please see this post for more details on treatments: Log Cabin Treatment.

Log Cabin Contraction

At certain times of the year I will get the odd complaint about our Log Cabins from buildings that have been installed in the Autumn and Winter, Early Spring. The height of the complaints will come in around July and August.

Some customers will be nice and ask for advise, others will launch into a big complaint and are not very pleasant to deal with on occasions.

I then have to gently walk through the problem with them until it can be resolved and 100% of the time it is the customer’s own making.

The pleasant guy asking for advice will locate the problem and it’s solved.

The unpleasant guy will demand we go on site and then find the problem for them and all of the time it’s when they paid a ‘Qualified Carpenter’ or a ‘Qualified Joiner’ to install the building as it cannot be their fault.  Unpleasant guy then gets very upset when we charge for our attendance.

To solve this I thought I would write a quick post about this seasonal complaint and here’s a few examples:

Logs have shrunk in the heat.

Contraction of Log Cabins

This quick piece is talking about the problems we have with contraction. No doubt, about six months from now, I will write one with the opposite problems, that of expansion, both are a powerful force in timber.

Throughout the articles in this blog I talk about expansion and contraction a lot and it cannot be overstressed the importance and the power of this. If you are going to own a log cabin you’ve got to believe me.

Here are some previous articles where I talk about this feature of timber in depth:

My online Log Cabin Advice Manual also talks about this.

Log Cabin Logs

A log cabin log is obviously made from the length of a tree and we try to pick the best bit close to the heart. It not going to grow or shrink much in its length but it can change quite a bit in its height when part of an install.

I’ve had a customer tell me ‘I realise wood moves but this is excessive’ It is not excessive, it is what wood does and it cannot be controlled or helped.

In the moisture content article above I reference some figures that will show a cabin has a potential to move a LOT!

Here’s a good example of a log cabin in contraction, followed by an expansion example. In either case you will see the untreated wood start to show. This is why I advise in other posts to remove the fascia and paint behind them so you do not see this happen either in contraction or expansion:

Contraction example:

Installation Problem

Of course none of this is helped if the installer is not aware of this or understands this and please believe me, anyone with ‘Qualified’ followed by ‘carpenter’, ‘joiner’ or ‘builder’ will make the same mistake as someone who has never built one before. The difference being of course your average customer will read the information before installing.

So why are we seeing these gaps and why am I having a complaint against our lovely log cabins?

Quite simply, the installer is trying to interfere with the movement of the logs and is restricting them moving. This will be things like:

  • Adding extra timber into gaps meant for expansion
  • Fixing door and window fascia to the logs
  • Fixing door and window frames to the logs
  • Installing shelves, electrics, brackets, 
  • Lifting door and windows up to fill expansion gaps
  • Fixing the logs in many other ways
  • Fascia in corner buildings above the door allowing the cabin to sit on the door frame

Here are some examples of the cause of all the above with pictures:

Fixed Fascias

Door fixed to the wall logs – luckily I caught this one as the picture was for a door query but you can see nails through to the logs and this is a potential complaint in either expansion or contraction. Thankfully the customer removed these before any problems was caused in about 6 months time.

Timber infills

During the winter the wood is likely to be at its biggest and sometimes customers will worry about a large gap they find above a door frame or a window frame. Without realising what it is for ‘Qualified’ …. carpenters, joiners, builders … will be tempted to fill the gaps;

Timber used to fill the expansion gaps.

DIY storm Kits, Brackets, Shelves, Curtains etc

I Haven’t really got pictures of these sort of things that I can show you as it may identify the customer’s cabin but this was an unusual one:

Strapping to act as a storm kit and bracing

Strapping and bracing. The customer had some sort of shelving system attached the sides of the cabin and I remember he was also concerned about bracing for storms as he was very exposed in the highlands. The ingenuity was very good but this was holding the cabin very rigid and when the summer got here gaps started appearing.

If you want to install shelves, black boards, bars, brackets etc you can do so really easily but please consider the expansion and contraction. The articles referenced earlier explains how to do this so you do not have any problems in the long run.

Electricity in Log Cabins

I wrote an article about Electrical installation in Log cabins ages ago and although I have let my personal accreditation lapse it still hold true and we reference this quite liberally, electricians must be made aware of the expansion in log cabins.

Here’s how to do it:

Flexible expansion to allow for the cabin to move.

Flexible expansion to allow for the cabin to move.

This is what can happen if you do not tell your electrician that a log cabin is made of wood and expands and contracts:

Log cabin has contracted and no allowance has been made for the trunking. This is a potentially dangerous situation as all the wire and terminations will be under strain.

Consumer unit is fixed across two logs, this will cause problems in both contraction and expansion and may cause numerous problems least of all it compromising the installation itself.

Summary of contraction in a Log Cabin

Log cabins move, whether it’s one of ours, someone else’s, regardless of thickness, all wood moves, it can’t be helped. It’s full of straws and these straws will suck in and expel moisture:

Layer upon layer of straws all drawing water for the tree. Many now support the Cohesion method theory where a tree draws its water using the tension of water.

Layer upon layer of straws all drawing water for the tree. These straws stay open and need to be treated to block them up.

You can see from the structure of the wood that these straws need to be blocked up, amongst other things this is the purpose of a good quality treatment and sufficient coats, these articles explain more:

I’ve said it several times, please don’t use anything cheap on any log cabin, we’re trying to inhibit the movement. A cheap treatment will not do this and you will have quite a bit of movement over the first year.

We do find though that after a year and the full season cycle we will never hear from a log cabin customer again. If you are going to have a problem with expansion or contraction it will be within the first six months of ownership as you will have either treated it well or the straws will start to collapse and die more.

If you have a log cabin that is showing these signs, before you complain to us or the person you bought it from whether it is our product or not please check the following:

Check for:

  • Fascia screwed / nailed to the logs
  • Any restriction to the logs at all
  • Shelves, curtains, brackets, fixings on the wall
  • Expansion Gaps above and to the side.
  • Finishes above Corner building doors.

This is all applicable to any log cabin, I hope it helps if you are seeing these problems whether you bought from us or another manufacturers building.
