George Barnsdale is renowned for high-performance timber windows and doors, crafted over time.

Since its founding in 1884 by George Barnsdale, the family-run business has become a cornerstone of the Lincolnshire village of Donington, contributing to both the local community and the broader construction industry.

We have worked on some of the most prestigious projects involving complex builds using retained facades, working with conservation officers, planners, acoustic engineers and more. We design, specify, manufacture and provide a full installation service.

George Barnsdale are timber window and door specialists, and they're proud of the knowledge, innovation and care that goes into every single product we make.

Every day, George Barnsdale are pushing to be better than the day before. How can we make better windows and doors? How can we preserve natural resources? How can we help our customers run successful projects? How can we uplift communities with thoughtfully preserved buildings?

We’re pioneers. Craftsmen. Mad scientists. Historians. Engineers. Designers. Project managers. We’re problem-solvers. We’re custodians.
