Whether you have a SheShed or another type of timber cabin, following these tips will help to keep your cabin in good condition for years to come. Read on to find out more!

Can a wooden cabin withstand High wind? Heavy rain? Earthquakes?

Many of our SheShed cabins are certified up to a high-wind category throughout New Zealand & some cyclone ratings throughout Australia. Depending on your location, the surrounding terrain & the direction of the prevailing winds, it can sometimes be best to discuss what wind rating will be required for your anticipated site with a local professional before purchasing, so we can offer you the best solution. Different kitset cabins within our range are designed to withstand different wind ratings, and additional bracing kits can also be purchase to increase the level of storm protection on your shed.

What are Storm Brace Kits and when are they needed?

Storm brace kits provide additional vertical tiedown bracing to keep your cabin firmly anchored in any storm conditions. These come standard with our traditional style Canopy kits, Brook River & Lake Cabin kits. Our modern Tussock, Coastal & Alpine cabins all come standard with built in metal storm braces to help reinforce anchoring.

Top tips for protecting your Sheshed cabin from the elements.

  • Seal any open knots and the exposed end grain on the timber.
  • Paint & seal all the timber on your shed using at least one coat of primer/sealer, then two top coats to create a weatherproof barrier.
  • Place gravel/scoria abound the base of the shed to stop dirt & mud splashing up on the walls during heavy rain.
  • Install a Storm Brace to help steady the structure in higher winds.
  • Keep the roof clean of any leaves & branches so rain can freely run off.
  • Keep any plants cut back from the walls of the building.
Preventing Leaks

SheShed kitset cabins are designed to be weatherproof, we source sheds manufactured only from high quality slow-grown trees, with CNC machined timber to achieve the snuggest fitting joints, however with the timber being a natural product we can’t guarantee that every board will be free of imperfections or blemishes.

The 4 main typical areas where water penetration can occur on any building is, through the roof, through the floor, windows & doors & wall cladding which is why we recommend sealing knots & blemishes.

  • If your roofing has been installed correctly to provide a continuous membrane over your new shed your roof will be leak free. Don’t allow moss or lichen to grow as this may create gaps in the roofing.
  • When installing your cabin, it is important to ensure that in a large rain event the level of the floor in your cabin is high enough above the surrounding ground level so that excess surface water, running across your garden doesn’t enter the building under the floor.
  • Maintaining your doors & windows, and regularly painting them will ensure the timber is protected against water ingress & moisture damage (remember to paint the underside of the doors & windows too), water droplets can stay on the bottom of the door & window long after the rain has finished. Also, correct installation & regular inspection of the door & window seal will ensure no water penetration occurs.
  • Sealing the timber externally & internally with a high-quality paint system will ensure the risk of water penetration through the wall boards is significantly reduced, and we also recommend to seal the knots with a paintable/ flexible sealant to prevent water from entering. (If you’re wanting to use a clear varnish to keep the timber look, you can colour-match any wood filler you use so it doesn’t stand out.)
  • Both treated and untreated timber can also sometimes leach or tannin bleed through the end-grain or knots in the wood which can cause a yellow/brown stain that is particularly visible on lighter colour paints. This staining can be reduced or eliminated by using a stain blocking primer when you paint your SheShed.
Heavy Rain

Heavy rain, changes in atmospheric pressure, and gusting wind can all cause a difference in atmospheric pressure between the interior of the shed & the exterior. In some cases, the pressure difference can create a wicking effect (absorbing of water by capillary action) where water can be draw through tiny cracks or through the natural woodgrain of the timber, sometimes visible as water droplets or it may be as subtle as a watermark on unpainted timber. Proper sealing & painting of the end grain & knots will help reduce this. Additional sealant can be used around the log notches, if the cabin is in a vulnerable location, however care must be taken to ensure that the sealant doesn’t prevent the natural movement of the timber. It a good idea to install small vents at a high level in the front & rear apex walls of the cabin, this helps to provide suitable cross flow to balance the pressure difference & reduce the effects of the weather on your cabin.


Due to the innovative notched & stacked construction of the log cabins, the performance of the sheds in an earthquake, provide superior protection against erratic movements caused by earthquakes, if built correctly on one of our certified sub-base designs, your shed will be suitable to withstand typical damages caused by earthquakes to traditional style buildings.

Weatherproofing your cabin is essential to keeping it in good condition for years to come. By following the tips we’ve outlined in this article, you can ensure that your cabin will be able to withstand all of the elements Mother Nature throws its way.
