Our Story
Our story began in 1980 when Engineer John Ellis founded our company with a passion for woodwork. He used his knowledge and experience to create high-quality double-glazed timber sash windows and doors. Over the years, we have grown, but we remain committed to the same high standards of excellence. We are proud to be a locally made, family-run business that reduces our environmental impact by installing 95% of our sash windows within 10 miles of our London workshop.
