Swainston’s Windows was founded in 1964 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 and Glazing providers in the North-East of England. 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. Swainston’s also offer a wide range of Composite doors which are all manufactured in-house by our own fully trained staff and come complete with hardware and frames.
