Swainston Windows



Swainstons Group have over 50 Years of continued Excellence.

Founded in 1964 we are one of the UK’s oldest, most reliable, genuine and respected manufacturers and installers of Windows, Conservatories, Doors and the Guardian Roofs & Extension systems.

Swainston’s are based in Stockton-On-Tees in the heart of Teesside. Originally specialising in fabricating and glazing wooden windows, today Swainston’s is one of the most established uPVC Window, Composite Doors and Guardian providers in England.
You can rely on Swainston’s to deliver the most innovative, beautiful and secure products, which are professionally installed for you as quickly, quietly and efficiently as possible.

With over 50 years of continued experience of providing our services and products to home owners, local authorities and the NHS. Total satisfaction, security, and complete peace of mind are guaranteed.

Offering both public and trade services since the 1970s in uPVC, Windows, Doors and Conservatories, you can be sure of a high quality product due to Swainston’s in-house crafting of single and double glazed units, eliminating risk from third party involvement and improving the turnaround time. Since 2004 Swainston’s have been based in a 20,000 square foot factory where we continue fabricate our own uPVC Doors, Windows and Conservatories. Our glass shop alone is now very extensive allowing us to cut, fabricate and supply units to Trade and public customers. The best addition to our product range is our Composite Doors, which are fabricated by our fully trained staff and come complete with hardware and frames.
Swainston’s are members of various recognised trade associations, ensuring standards are maintained on a day-to-day basis and our customers benefit from the high level of craftsmanship applied to all of our products. This year we have been accredited within the Contractors Health & Safety Assessment Scheme for which we are enormously proud, having met and maintained all the standards set over the past 5-10 years.

Since 2008 we have been awarded various contracts to supply and in some cases fit uPVC Windows, Doors and Conservatories to properties owned by local authorities, including Middlesbrough, Stockton, Darlington & Hartlepool. The most popular item we supply to local authorities is our Composite Doors.
With high demand, in 2010 we decided to branch out and offer more services within the construction industry completing works for companies who install home dialysis units. We have also carried out works for private health companies including mental health units working under high security.

Upon the advent of Solid roofs for conservatories and Aluminium bi-folding doors we have looked into various products and systems to ensure they met our high standards. We have concluded that the Guardian Warm Rood system and the Smart aluminium bi-fold door systems meet those standards and have successfully installed several of them for our customers.
