‘We recently had a window and front door fitted by Square Deal Windows Home Improvements and could not fault the service. Not the cheapest quote we had but having had a bad experience with another company we went with the reviews. Personal service throughout with no pressure to have extra’s. Communication was excellent and all fitted within the specified time frame. The fitter was friendly, clean and tidy. He didn’t rush the installation and we are really impressed with the quality of workmanship and attention to detail. The house had recently been decorated and when he left you wouldn’t have known he had been there. We would definitely recommend them to anyone and would happily use them again. Thank you.’
