Welcome to Blackthorn Timber Windows!

From traditional sliding sash windows to folding sliding doors, cottage-style windows to modern reversible casements. Whether your home is urban or rural, Victorian or 21st Century, we have the windows and doors to suit it.

With bases in the North-East and Yorkshire, Blackthorn Timber Windows has gained an enviable reputation for the high quality of our windows and doors and for the skill and attention to detail of our installation teams. We offer installation services from North Derbyshire right up to Edinburgh, including the whole of Yorkshire, Co. Durham, Tyne & Wear, Northumberland, Cumbria, South-West Scotland and up through the Borders. For the rest of the UK we supply windows and doors without installation, although we are always prepared to discuss individual projects beyond our 'borders'.
