“I found this company online and organised a meeting straight away. The sales guy was friendly and helpful and really wasn’t hard selling. Everything looked good so we went ahead. The fitting team came within about three weeks and were professional, neat and tidy, and we are very pleased with the results – four windows and double patio doors. We are very happy to recommend them.”
