This was the third job that we've used The Sash Window Workshop for. A high quality product each time, fitted by professionals who are also nice people.

Fantastic experience overall; will be coming back to them for our final window, when we do the bathroom. The workmanship and material of the windows is excellent quality and look beautiful (we chose Accoya wooden frames). Their employees were easy and helpful to work with throughout the process, from design and survey, through to the installation process.
Installation went perfectly to the predicted schedule (3 days for 15 units across 4 rooms), even with one of the glass units having cracked during transport and having to be replaced mid-install.

Having used the company before, from first sales visit, Surveyor and fitting, the service has been superb. Nothing is too much trouble. The new sash windows are superb & totally match the windows in the rest of the house. Would definitely recommend to anyone.

Good work all through the job from the Sash Window Company, from the first visit by the surveyor to the fitting of the windows. A small adjustment was needed to a screw fitting and it was fixed immediately. Highly recommended.

Excellent company. Couldnt recommend more highly. Every aspect outstanding: set up, surveyor, window quality, fitting, office admin, scaffolding company. The windows enhance the house enormously and are a joy to open and close.
