Customer in London

“The windows are fantastic. Solid, well made, nicely installed. The work would have been completed in 3 1/2 days but removal to the bays revealed structural work that needed to be done on the house itself. ERW completed this work at no extra cost. Coming back on an further day.”

Customer in London

“Joel and his team did an excellent job in replacing my windows, and I am very happy with the finish. They arrived on time and left my flat very tidy and did not cause any damage. The quote was competitive. I need a slight adjustment made to my windows two months after they had been fitted, Joel responded very quickly to my request and made the change within days - impressive. I would Energy Rated Windows to my friends/family and would definitely use again.”
