I had a PVC window that was stuck on the latch so would neither close or open. When I ‘phoned David he was very helpful, even giving me some advice on what I could do which might resolve the problem. I opted for him to call to fix things. Some days later David phoned me to make arrangements to call the next day. When he arrived he identified and fixed the problem without fuss. He was very friendly and professional. Payment was made easy by way of a portable card reader. I would have no hesitation in recommending David.
