Pressure treated sheds are sheds built using timber that has chemicals and preservatives forced into the timber in a vacuum. This provides it with much greater resistance to rot and decay than dip-treating it but it is more expensive. Pressure treatment will have to be performed by professionals before the point of sale. There’s also no need to re-treat a pressure treated shed (at least not for a long time).

If you live in the UK, we’d advise it. Due to our temperate and often unpredictable climate, rain, damp air, and moisture are sometimes unavoidable. Various organisms, from tiny bacteria and fungi to woodlice and insects, are naturally attracted to wood, but never more so than when it’s wet.


That’s why when you lift up a tree trunk or old plank of wood that’s been left lying on the ground, you’ll find a whole crew of creepy crawlies that have made themselves a new home. So if you don’t want that to be your shed, we suggest going for the option to pressure treat timber. Pressure treatment repels insects and protects against rot and decay.

Pressure treated wood can prevent rotting and wood damage for fifteen years or even longer. During this time you shouldn’t need to treat your shed. That’s why our BillyOh pressure-treated sheds come with a 15-year guarantee against rot, decay, and insect infestation.

While you can use wood treatment products on your garden shed, pressure treatment at our plants is done by professionals through an industrial process. Opting for our pressure treatment will save you not only time but money in the long-run. With dip-treated sheds, although a viable option, you’ll need to retreat your timber at least once a year. Moreover, the effects of pressure treatment cannot be achieved through shop-bought wood staining products.

Pressure treatment allows preservatives and chemicals to penetrate right into the grain of the wood, whereas dip-treatment refers to the practice of treating wood with a water-based product to give it short-term protection from rot and bug infestation. It protects it on the surface, but the impact will fade over a much shorter period of time. This means it’ll need re-treating at regular intervals.

Pressure treatment adds an extra layer of protection and a massive boost to help the wood fight off rot, but it won’t make it completely waterproof. In order to boost your wooden shed's water resistant qualities, fill any cracks or gaps with caulking or expanding foam. Any for more tips, check out our guide on how to damp proof your shed.

Yes you can. But it’s important to make sure your pressure-treated shed is completely dry before doing so. If your timber has been kiln-dried that’s fine, otherwise leave your shed out in dry conditions for a period of 2-4 months. Then make sure to use an appropriate primer and paint like latex.

Pressure treated wood is wood that has had preservatives and chemicals introduced to it in a vacuum. Unlike dip-treated wood, these penetrate beyond the surface of the wood and protect it for longer against rot, decay, and insect infestation.

Although a more expensive solution to things like rot and decay initially, pressure-treated wood is superior to dip-treated wood. Instead of a surface coating of mould-resistant treatment, pressure-treating wood penetrates the material with these preservatives. Using pressure-treated timber in your garden shed can help improve its usage life.

It can vary on where you live and the weather but our BillyOh pressure-treated products come with a 15-year guarantee against rot, decay, and insect infestation.

A dip-treated shed will offer perfectly adequate protection against rot, decay, insects and the weather. However, it will require more (and more regular) maintenance than pressure-treated timber. If you plan to do more than use your garden shed for storage, we suggest opting for a pressure-treated shed.
