We took a risk as we didn't know the company but we followed a gut feeling & good reviews. Our cottage now looks lovely with all new windows (8 windows plus sliding patio door) and front door. Paul was very patient & helpful while we decided what we wanted and amazingly, considering the pandemic effect on materials worldwide, the work was done exactly as had been estimated. The fitters were professional, very tidy & pleasant throughout & all went smoothly. It was a big outlay for us but the price was excellent and so was the workmanship and communication. I've already recommended them to neighbours and friends.
