Replacement of 7no windows
Complete survey carried out for 7no windows then competitive detailed quote received which avoided a return to measure.Bryony and George gave us an excellent service and kept in touch throughout
George advised on a suitable frame supplier to match the existing window profiles from the survey photos.
Installation started and completed on time and the team were very friendly and tidy.
Minor problem with one glazed unit scratched/material trapped was sorted out within a couple of days with no quibble.
I would definitely recommend GM Windows and Doors.

Purchase of Sliding Patio Doors
I was very impressed with the company from the start. They were easily contactable, extremely helpful and gave me a competitive price. The 2 lads who came to fit the patio doors were very respectful of my property, worked efficiently and tidied up after themselves. I would have no hesitation in recommending this company.
