We recently had several windows and a French door installed. The installation was completed by Ben and John and it was quick and efficient, despite the fact they had to deal with awful weather conditions. They were both polite and courteous and cleaned up before they left the property. The windows look good and I have noticed a reduction in the level of noise I can hear from outside our property. The reason I have given 4 stars is the back office felt slightly disorganised . We had our date of installation changed a few weeks before the originally agreed date and the scaffolders which were required arrived on 3 separate occasions to erect it (although the scaffolders themselves were excellent and very polite)
