About Us

Dunster House Ltd began as a windows and doors manufacturer in 1994. Each of the Company founders; Chris, Pamela, Alexander and Andrew, have spent years building the windows and doors by hand. This first hand experience runs throughout the company, meaning we can assure you of the high quality finish of each and every window and door we make.

We have expanded a lot over the last 25 years, as have the products we produce. We now manufacture timber Garden Buildings such as Log Cabins, Garden Offices and Climbing Frames. Our continued success means we have expanded far from the small factory on Dunster Street in Northampton.

We now have 14 factories spread throughout the UK and Europe. These factories allow us to have complete control of the products we research, design, develop and sell to potential customers.

We still manufacture and deliver uPVC windows and doors. However, rather than making them by hand, we now have specially trained team members dedicated to the construction of our windows. They are produced at our headquarters in Bedford. We have invested in specialised equipment to help us make premium glazed windows that you will be proud to have in your home.

By ordering your windows and doors from Dunster House, you can be confident you are ordering from an established company. You can order your Windows and Doors from our online store. Here you will find various options and styles for your home.

We are so confident in our products, we offer a multitude of warranties and guarantees. Find out more details regarding these on our Terms and Conditions page here. Knowing we are the best on the market, we offer all customers a price promise, meaning "You won't find the same quality product, level of service or price to match - If you do, we guarantee we can beat it." More details regarding the price promise can be found on our Terms and Conditions page.
