What is Pressure Treated Wood?

When it comes to quality, low maintenance, and ensuring the longevity of your timber, the most important feature to look for is full and proper pressure treatment. We are the experts on pressure-treated timber and we pride ourselves in being able to offer pressure-treated Sheds, Climbing Frames, Gazebos and Garden Offices. You may be considering purchasing a product from another company which claims to be pre-treated. But be careful! This product might only be ‘dip-treated’.

We know our products are made to last, and this is why we can also offer a 10-year guarantee on all of our pressure-treated timbers and products.

What does ‘pressure-treated timber’ mean?

Pressure Treatment is the forcing of chemical preservatives into the wood. By doing this in a large kiln, we ensure that all surfaces of the timber parts are exposed to the pressure treatment, protecting the entirety of the timber and reducing the likelihood of rot or insect infestation as a result of moisture absorption.

Why is pressure treatment so important?

When buying a garden building or climbing frame which is designed to live outside all year round and be exposed to the elements, we know that you do not expect to have to treat and maintain it regularly.

Can you paint pressure-treated wood?

A quick coat of clear water repellent before a wet season is all a pressure-treated product will need, and with that, it is sure to last. You might also want to paint it in your chosen colour, which is fine too! You do not need to wait to paint pressure-treated wood supplied by Dunster House.

What do we mean when we say ‘dip-treated’ timber?

You may be considering purchasing a product from another company which claims to be pre-treated. But be careful! This product might only be ‘dip-treated’, meaning the manufacturer might have tried to keep costs down by just ‘dipping’ the ends of the timber in treatment, and leaving it to dry. This may give the appearance of pressure treatment, but in reality, this product will not be fully protected and will certainly not last as long or require as little maintenance as a truly pressure-treated garden structure.

Is pressure-treated wood safe to use in your garden?

Pressure-treated timber supplied and used in our garden building products is not toxic and is 100% safe to use in your garden. The treated timber has been left for a sufficient amount of time to dry and be sold as a domestic product.
