Great work from Phair Windows, I had Jason and Ethan come out to carry out some work on our window. The lads were respectful, efficient and professional. We are very happy with the conduct and service of the company. I highly recommend.

Had my windows done with Phair windows 3 years ago with a very competitive price. I was so impressed that 3 years later when my window was jammed they came to repair it. Ethan was excellent, very fast and repaired the window immediately. Great service from the start and still ongoing! Thank you

We used Phair Windows for a new tiled conservatory roof and inner plastering. The company were best on price and quality of work was highly done. It started with a visit from Tom the company salesman who understood what we wanted and assured us of what can be done. The office team of Jake & Boris were friendly and importantly communicated well with us throughout the job. The building team of Dan and Carl got the job done professionally and came up with good solutions to problems that arose. We had a few blown windows in another area of the house which they are replacing for us free of charge. Nice touch. Would recommend to other home owners to use this company 👍

I had French doors installed in August 2025 and returned to have five windows replaced in August 2026. I truly don't know how to express my appreciation. Phair Windows has an outstanding salesperson named Tom. The staff, including Boris, Leon and Lincoln, are down-to-earth and hardworking. This is an all-around brilliant local business that you should definitely support. Thank you so much! Faduma

I have recently had a new composite door installed by Phair Windows, Leicester and am very happy with it. My installer, Lee, was efficient and left no mess. He went above and beyond as he helped me with a couple of other doors that weren't closing correctly. I really appreciated that. I also needed more of the special keys and Phair reimbursed me for several of these and came back later to touch up a couple of marks and fit another door accessory. Everyone was extremely helpful and kept me informed every step of the way. Overall, I couldn't fault Phair Windows. Their price was literally half of what I had been quoted by one of the 'major' players in the business who favoured 'hard sell' tactics, and they guarantee every part of the door for 10 years, which is awesome. I would wholeheartedly recommend Phair Windows to anyone who appreciates great service with excellent aftercare.
