good service and products
Good service throughout. Good communication, no pressure selling. The windows are well made, open smoothly, and look slim and unobtrusive. They effectively deaden the street noise outside which is what we wanted, Installers cheerful and patient when faced with over anxious clients, worked quickly and cleared up neatly afterwards.Verified reviewerJob location: WC1RResponse from Sash Windows London

Quality windows by Sash Windows
Sash Windows did a great job replacing 4 windows in our house. From process from the initial design and measurements to the final fittings was very smooth and straight forward. The installation team was friendly and professional and they completed the work in 4 days. They even hoovered and tidied up!

Great experience!
I've had a great experience with Sash Window. They replaced two of the main windows in my new flat and the process was flawless. They assessed the situation properly, suggested a plan and take care of the installation. The previous windows were rotten and tilted so big kudos to them to complete the installation of the new ones.Verified reviewerJob location: NW6Response from Sash Windows London
