Pressure Treatment

For a Shed that's built to last, our pressure treated-sheds are some of the best. We have a wide range of pressure-treated sheds that are built to withstand the elements and keep the contents of your shed safe.

Our robust pressure-treatment procedure gives our wooden boards long-lasting protection. A dip-treated shed means less maintenance and more time using your shed for whatever you need it for. We have a great range of garden sheds that come with a pressure-treatment option, so you don't have to worry about picking a model that doesn't suit your needs just for that extra bit of protection.

And, speaking of protection, did you know that all our pressure-treated garden buildings come with an amazing 15-year Guarantee? So for robust and long-lasting sheds that transform your garden space, choose a pressure-treated shed from Garden Buildings Direct.

Why Go For A Wooden Shed

Here at Garden Buildings Direct, we've got timber building models with wide-opening double doors across a massive range of sizes. With options for tongue & groove and overlap cladding - you can pick your choice of cladding material. And, built with high-quality European-sourced timber as a durable material, our BillyOh buildings are designed to be hardy and long-lasting.

Garden Buildings Direct are one of the UK’s leading manufacturers for quality wooden sheds. With an enormous range of versatile garden buildings available, our wooden sheds for sale are purpose-built to withstand even the heaviest elements of British weather. With choices from overlap sheds and tongue and groove-clad sheds, we provide sheds that are as weather-resistant as possible. All of our wooden sheds offer loads of options to customise things like size and treatment so you can turn even a cheap wooden shed into a DIY workshop, potting shed, or whatever suits your needs.

Choose from different features and design styles like apex, reverse apex, or pent roofs. Windowed and windowless options for wooden storage sheds mean that you can choose between increased natural light or privacy and security. And all our BillyOh pressure-treated sheds come with a 15-year guarantee against rot, decay, and insect infestation. So you know that, at Garden Buildings Direct, you’re investing in a quality outdoor building.

Quality

With sheds by price, size, cladding options and even windowed and windowless options for the choice between natural light or more secure storage, the possibilities are endless! And with green mineral roof felt and tongue and groove flooring included as standard, you can get the most for your budget.

Guarantee

Whilst our garden buildings come with a 10-year guarantee, we can increase this to our 15 year anti-rot guarantee on pressure treated sheds against rot, decay, and insect infestation. So for longer-lasting protection and less hassle, opt for a pressure treated garden shed.

Finance

We even offer finance options on our pressure treated outdoor sheds with a minimum purchase of £560!

Tongue and Groove Cladding

Tongue & groove construction is ideal for timber framing for strength. And, with high-quality materials at an affordable price, you can be sure of a weather-resistant shed. With tongue and groove boards for the flooring and groove cladding panels for the walls, every aspect of your shed will be well-protected against the elements.

Our tongue and groove panels are 11mm thick as standard with options on many of our sheds for thicker cladding. Tongue and groove cladding panels are pre-engineered to interlock together. This design gives our wooden garden shed strength and weather protection. The T&G finish creates a durable seal against water ingress, which is part of why we can also offer a 10-year anti-rot guarantee on all tongue and groove products.

Pressure-Treated Shed Timber

And with the option of pressure treatment, you can add to the customisable and quality features that our BillyOh buildings are known for. Unlike dip-treated sheds, our pressure treated timber affords extra protection against rot and decay.

On our pressure-treated sheds, our guarantee increases to an extended period of 15 years. That’s because our pressure-treated European-sourced timber introduces chemical preservatives to the building materials whilst sealed in a vacuum. This helps them to penetrate our high-quality timber and can protect your shed against rot for years to come. It’ll also require less regular maintenance than non-treated timber and may work out cheaper in the long run.

Sheds By Roof Style

You can even shop our pressure treated sheds by roof style to get a contemporary or more traditional look without compromising on long-lasting protection.

Pent Sheds

For a pent wooden shed that's been pressure treated, you can shop directly from our range here. A more contemporary roof design, pent sheds feature a modern and attractive appearance with their single sloping roof panel.

Apex Sheds

Unlike a pent roof shed, our pressure treated apex garden sheds feature a more traditional silhouette with two sloping roof panels meeting at their highest point at the ridge.

Expert Range (Storage Sheds)

You'll even find our expert sheds in our range of products that come ready-pressure-treated. One of our tongue and groove timber ranges that's incredibly popular among customers, we knew we had to offer the same quality materials in our Expert range in pressure treated models. Perfect for everything from storing lawn mowers to a DIY workshop.

Planning Permission

Pressure-treating your garden shed won't affect the need for planning permission. As long as your shed's ridge height is no higher than 4m (3m max for a pent shed) and your eaves height doesn't exceed 2.5m, your building will fall under 'permitted development'. We always recommend, though, that you place your premium quality building on a level base on level ground - whether that be a timber sub-floor or a concrete base.

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.
