Efficient and fair priced

Excellent repair work carried out on my "ancient" casement windows, fixed all the rot in less than a day, dust sheets used throughout and cleaned the window glass after finishing which was very kind. Daryl worked hard and was very organised. TK

Excellent workmanship and communication throughout. A very well thought out work plan and impeccable logistics given the complex circumstances. The window quality is actually better than I imagined and professionalism from all members of the team I had contact with was impeccable. Highly recommended, I am especially grateful to Cole and Matthew for showing patience with what must have been quite a difficult task to complete. Thanks - Roger Croudace
