Great service good quality windows. Not cheap but you get what you pay for. Had six windows two doors fitted about 4 years ago still look like new and the house is quieter and warmer. Want last two done phone Peter came up measured up at my convience couple of days later. Fitting in about three weeks. Can't fault them.

Excellent installation service with helpful, friendly staff. Best price and best quality windows and doors compared with all other competitors and recommended by more friends, relatives and customers when compared with others available.

John Denton

They fitted UPVC replacement windows for us. They dod an excellent job. They turned up on time, and were very professional, clean & concientious. We asked them to come back and adjust a hinge so we could open a window better for cleaning, and they came back the same day.
