The Sash Window Workshop: Timber Windows and Doors

Established in 1994, The Sash Window Workshop is a premium manufacturer and installer of traditional timber windows and doors in London and the South of England. We also offer a supply only service for the rest of the UK and a repairs service for wooden windows in London and the South.

Operating out of our factory in Berkshire, we manufacture and provide installation of secondary double glazing, new sashes into existing frames (replacing just the moving parts) and complete new sash windows, wooden casement windows, timber French doors, Front doors, Stable doors, Sliding doors and Bi-fold doors. Our wooden window repair services include a draught sealing and overhaul service.

The majority of our replacement timber windows and doors are double glazed. However, we can also manufacture single glazed, or use our heritage glazing, where double glazing is unlikely to be approved (listed buildings and some conservation areas). All our new windows and doors come fully factory finished and are draught proofed.

All our new wood windows and doors are bespoke and made to meet your individual requirements.  We use a timber called AccoyaTM, which is selected for its durability and stability.  We offer a variety of different glass and ironmongery options.  Our replacement windows and doors are made and installed to provide a high quality performance and be energy efficient.  All our work comes with extensive guarantees, including a 50 year anti-rot guarantee for new windows and doors made in AccoyaTM.

We strive to provide all our customers with a high quality product and exceptional customer service and are proud to be a Which? Trusted Trader and have a 5 Star Trustpilot Rating.  We are an independently run business and believe it is important to listen to our customers requirements.  Our highly experienced team of sales surveyors and installers will ensure that you are provided with the solution that meets your needs.
