How to stop a shed from rotting
Welcome to our guide on how to prevent your shed from rotting.
All sheds are exposed to some pretty nasty weather during their lifetime. But there are some simple yet effective tips and tricks that we can employ to make sure they last a lifetime. Most of them are a lot simpler than you may first think.
When water gets inside wood it forms a perfect place for microbes, fungus and wood eating moulds to decay the timber and weaken the structure, therefore it is important to stop the water entering at all costs.
1 - Use a non absorbent material such as recycled plastic beams under your shed -
Wood is absorbent, meaning it will soak up moisture, but Having non-absorbent plastic or concrete runners under your shed will stop the moisture from being able to be wicked up into the timber flooring. You may have noticed in the past that the first part of a shed to rot is the part closest to the ground.
2 - Treat your shed with an oil-based preservative once every year -
We advise treating during the start of the warm summer months. At this time of year, the timber is expelling any moisture it may have picked up during the rainy winter period and many small cracks and pores are beginning to open up. These cracks and poses are perfect places for the oil-based treatment to get deep in to the timber to help with preserving the wood. The oil-based treatment will also create a protective barrier on the outer face of the cladding that will cause rain to run off instead of being soaked in.
3 - Make sure your roofing felt is in good condition -
The mineral felt on your sheds roof is one of its best waterproofing features. It covers the timber slats or OSB3 boarding that is used to construct the roof and stops any water for getting in. If you have any holes in your roofing felt you should use a patch kit to seal it up or replace the felt straight away. The inside of garden sheds are not typically treated so if water gets in, it won’t be long unit the dreaded rot begins.
4 - Buy a good quality shed to begin with -
If you buy a 6×4 shed from an online retailer that costs £250 including delivery you are going to be buying another shed in around 3 years time. These “BARGAIN” sheds are built using weak framing timbers with very thin cladding and simply will not hold up to the British climate. We advise visiting one of your local bespoke shed building companies and having a look at the quality and craftsmanship that they put in to their timber buildings.
5 - Keep on top of maintenance-
Accidents happen! You are having some work done in the garden and a mini digger has hit the shed and snapped the cladding. Do not patch it up with gaffa tape and some tarpoline. Head on down to your local timber merchant with a sample of your cladding and get it patched up properly right away. Most merchants will be able to provide a very close match to the cladding you have. Some may even have the correct machinery to run a piece to the exact same dimensions.
6 - Put your shed in direct sunlight -
If possible, put your shed in the corner of the garden that gets the most sunlight. With our rainy British weather it is very important to try and dry out any wet wood as soon as possible. By placing your shed in the sun the moisture will be pulled out of the wood and evaporated in to the air, greatly reducing the amount of time that harmful mould and timber eating fungus gets to take hold.
