The Sash Window Workshop

Established in 1994, The Sash Window Workshop specialises in the manufacturing, installation and draught proofing of traditional timber windows and doors for period properties in London and the south of England. We also offer a supply only service for new joinery nationwide. Operating out of our factories in Berkshire, we can manufacture and install new sashes into existing frames (replacing just the moving parts), complete new sash windows, casement windows, French doors, Front doors, Sliding doors and Bi-fold doors. We also offer a secondary glazing service and a draught sealing and overhaul service. Our bespoke replacement windows and doors are manufactured and installed 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 strive to provide all our customers with 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 of sales surveyors and installers will listen to you to ensure that you are provided with the solution that meets your needs.
