Mr Graham facer Gwendoline Drive Countesthorpe had phair windows to replace three double glazed unit, Work was done very professionally and in good time. Team was polite and friendly. Good price. Would recommend. Thanks stacie goodreidMay 7, 2025. I used Phair windows to replace multiple windows and doors in a property I’ve just purchased. They were recommended to me by a friend and I’m so glad I chose them. The service was great, good quality products at a ‘Phair’ price. The lads who came to install were polite, tidy and efficient. I’d recommend anyone local to use their services. tina stringerMay 6, 2025. I had originally left a one star review due to lack of response. Since then the company owner has been in touch to explain slow response. He also came out to have a look at our window handles and also found another couple of window problems. Overall they were very thorough, and came for a second visit to replace the handles. They were very professional and efficient and I am happy to recommend the company to anyone who needs work done on glazing/window replacements. Chloe PughApril 22, 2025. Very happy, great service. Would recommend to anyone that needs new windows Adam BirrellApril 16, 2025. Had all my windows and exterior doors replaced with these guys. It was an easy and smooth process. The quality was spot on with clean and efficient fitters. Highly recommend!!! Paul R CarrApril 10, 2025. These guys are fantastic! They did a big job in just a couple of days and the quality the work was incredible! They were so respectful and tidy, with very little disruption- and we kind enough to do a few little extras here and there on our sills etc… They could not be faulted! 100% recommended and will definitely use again! Shoaib AhmedApril 2, 2025. Just had a door and new windows fitted by Phair Windows. Couldn't recommend them enough. Big thanks to Eric, Mike, and Lincoln who did an amazing job. Highly professional and friendly. Also, big thanks to Jake who came round to do a quality check to make sure I was happy with the service.
