Sash Window solutions, headed by Andrew, made the whole process stress free . The timing of the fitting was negotiable and everything was made clear. Questions were answered and concerns addressed The work was done in one day, carpets and furniture protected and everything cleared up neatly afterwards. And the windows look lovely.

Amazing service From Alen and his team. His quote beat the competition by far, but without any compromise on the windows. We were only planning to have new wooden double glazed windows for the front of the house, but were actually able to have new windows for the whole house. Alen also made suggestions which we had not thought about. He said we would have beautiful new windows and he has delivered. Clean, polite and kept informed throughout the process. Wholeheartedly recommended.

I recently had Luke and his team widen an opening between two rooms in my property, which was a sizeable job requiring the installation of a steel beam. The work was managed efficiently, and great care was taken throughout the project. I’m very pleased with the results and would highly recommend Luke and his team for their professionalism and attention to detail.
