The Sash Window Workshop

Established in 1994, The Sash Window Workshop specialises in manufacturing, installing, and draught proofing traditional timber windows and doors for renovation, extensions, and new build projects. We offer a supply-only service for new joinery nationwide with a supply and install service and draught proofing service in London and Southern England.

Operating from our manufacturing facilities in Berkshire, we can manufacture and install new sashes into existing frames (replacing just the moving parts), new sash windows, casement windows, French doors, stable doors, front doors, sliding doors, and bi-fold doors. We also offer secondary glazing for listed buildings.

Our bespoke replacement windows and doors are designed to be energy efficient while also being in keeping with the architectural style of the building. All our work comes with extensive guarantees, including a 50-year anti-rot guarantee for new windows and doors made in Accoya.

We pride ourselves on providing a high-quality product and exceptional customer service, reflected by our ‘Excellent’ Trustpilot rating and having won Which? Trader of the Month Award multiple times. Our highly experienced team will listen to you to ensure that you are provided with the solution that meets your needs.
