UK Based Company

Check out our range of high quality, heavy duty pressure treated sheds. Made from Slow grown Spruce instead of cheap Pine and treated using out high-tech pressure treatment facility, we guarantee our pressure treated timbers for 10 years. That’s how confident we are in our products!

Should I buy a pressure treated shed?

Pressure-treated wood is infused with chemicals that enhance its resistance to rot, decay, and insect damage. If you live in an area with high humidity or frequent rain, a pressure-treated shed can provide better durability and longevity compared to sheds made from untreated wood. A pressure treaded shed is highly recommended for UK customers.

Important!
Many sheds sold on the UK market will use dip treatment as a cheaper alternative to pressure treatment. This method can be far less effective offering less protection of your shed. Find out more about pressure treated sheds vs dip treated sheds.

Can you paint a pressure treated shed?

To keep the shed properly protected, we recommend applying a good quality water repellent to the external timbers. A clear solvent based treatment minimises the amount of water the timber absorbs during rainfall. You can apply this treatment directly onto the timber. Read more about how to maintain a wooden shed.

At Dunster House, we understand the importance of having a reliable and robust outdoor storage solution for your garden. Our collection of pressure treated sheds is specially designed to offer unmatched durability and longevity in the ever-changing UK climate. Say goodbye to worries about rot, decay, and insect damage, and invest in a high-quality shed that will stand the test of time.

Investing in a pressure-treated shed is a wise choice for anyone seeking a durable and long-lasting outdoor storage solution in the UK. Enjoy peace of mind, knowing that your shed will withstand the test of time, no matter the weather conditions. Browse our extensive collection of garden sheds and find the perfect pressure-treated shed that meets your requirements. Shop now and transform your outdoor space into a well-organised and clutter-free oasis.

DIY Friendly Sheds with Unmatched Features

From responsibly sourced slow-grown Spruce timber, 4mm toughened glass windows (instead of cheap styrene), tamper-proof hinges and timber that is meticulously pressure treated unlike many competitor sheds which are simply dip-treated, a Dunster House shed is ideal for anyone that is looking for a quality shed and great value for money.
