On both visits (1 st to measure & 2 nd to install) the service was excellent. The replacement sealed units blend in perfectly with the remaining ones and we were very impressed with the price. Glazing Masters was very professional, friendly and knowledgeable and left the site clean. They even solved a problem we had with another window that didn’t need replacing and also helped me put the net curtains back. I was initially a bit worried about sending my own measurements in but it saved an extra visit and gave us an idea of the cost of the new sealed units before ordering them. The time between ordering and fitting was also very impressive. All in all Glazing Masters provided an excellent service and I will have no hesitation in contacting them again in the future if further windows need their service or recommending them to others.
