Timber care and maintenance

Timber must be protected form weather elements, mainly form rain and Sun’s damaging UV rays. Proper waterproofing and sealing the timber on all sides is very important to make our cabins and homes last for as long as you live, plus your children’s lifetime. These are important warranty conditions. Please find all other warranty conditions here.


To protect the building from water damage, preserve the timber or at least bottom boards with a CN (Copper Naphthenate) timber protective emulsion. Read instructions and watch video of preserving the first layer of the structure. Sealed bottom boards will stop any moisture penetration that comes from the top of flashing installed around the perimeter of the building.

Another important waterproofing point is the roofing. Make sure corrugated roofing is installed according to the roofing manufacturer’s instructions with sufficient rain gutters and down pipes to dispose of rainwater.

After the assembly of timber parts is finished, cover your new building structure with the waterproof sheets even it is only for a night. Roofing must be put on as soon as possible to waterproof the building and avoid water damage to the timber.

Sealing the timber on all sides

It is important to seal [paint or stain] the timber on all faces inside and out using quality timber paints within 21 days after the assembly process is finished. That way, there is no moisture loss and we maintain the integrity of the wood cell structure of the timber.

Natural timber cracks, holes need to be filled with the timber fillers to get an even surface for a perfect finish. Also, any surface imperfections should be sanded and sharp edges rounded. This will ensure better coverage of paints and protection. On average, you will have to repaint it every 10 years or re-stain it every 2 years, but this will depend on how the timber is exposed to the weather elements. Please refer and follow the paint manufacturer’s instructions.

We strongly recommend to watch the video and read the tips and instructions below on how to seal the timber and what should you particularly pay your attention to.

Architraves around doors and windows

Window/door architraves and fascia boards must be painted from both sides. It is usually done after construction by taking them off, sealing the back and then re-fixing them back. Following these 3 simple steps will extend the lifespan of the architraves:

  1. Unscrew the architraves
  2. Seal all timber surfaces and
  3. Screw them back on

Fascia boards

The same process applies when we get to fascia timber boards around the roof line. Generally, the ones behind the gutters and the steel fascia/flashing that go on top of the timber fascia boards. If you install the unsealed, you’ll never be able to seal them after the roofing is installed. So, seal them on all faces with at least two coats, three is desirable, prior to fixing. And then that piece of componentry will outlast you and get the service that you are looking for in this product. This is not to be missed step before installation. Seal all timber surfaces of fascia boards before installation.

That same principle applies to the walls. The walls must be sealed form both sides prior or in most cases after the installation.

Pay particular attention to the end grain here, because that is the number one source of moisture uptake in the walls. Even if those nibs are going to be covered with timber C-section covers, we strongly recommend the end grain is sealed with at least three coats of suitable product prior to the covers going on. And that will minimize any checking and any moisture uptake. Do it as soon as possible, because the timbers supplied are kiln-dried from the factory, so the trick is to seal it and keep the moisture out. That can even be done on the same day as construction. Don’t wait.

And remember to seal and waterproof the bottom of the first layer of wall-boards prior to it being fixed to the steel/timber sub-floor or the concrete.
