Common FAQs About Window Repairs in Leicester
What causes condensation in double glazing?
Condensation and moisture trapped in double glazed windows is a major sign that the seal has failed and needs replacing. Once the seal is breached, this allows water vapour and fresh air to get inside the glass panes. It’s one of the most common double glazing problems, and replacing misted windows will improve the thermal efficiency immensely.
Can misted windows be repaired?
Yes, misted windows can be repaired. The process typically involves replacing the failed double glazed unit with a new one. This restores the window’s clarity and insulation properties, addressing issues like condensation between the panes.
How does your window repair service work?
If you have a misted window issue, simply call us to speak with one of our glazing experts and schedule a call out. We will then measure the window and order a new double glazed glass unit. Once the new glass is ready, our glazier will return to install the unit.
Do you repair doors?
Our team can service and repair front, back, uPVC doors, composite doors, bi-fold and French doors as well as re-align and replace door panels. We also can help with the installation of locks, hinges and handles as well as cat flaps. We can also install and replace existing doors if you so wish.
Is it worth replacing misted windows?
Replacing misted windows is definitely worthwhile for several reasons. Misted windows indicate a failure in the sealed unit, leading to reduced insulation and energy efficiency. New double glazed units can restore clarity, enhance insulation, and improve the overall appearance of your windows. Fixing the issue promptly can prevent further damage and maintain the value of your property. However, the final decision will depend on factors such as the extent of the damage, the age of the windows, and your budget.
Do you repair conservatories?
Yes, at Phair Windows, we offer conservatory repair services. Our expert glaziers have over 25 years of experience and can help with various issues, including condensation repair for all styles of windows within your conservatory, fixing steamed-up double glazing, cloudy panes, and broken glass quickly. We also specialise in replacing misted windows and foggy glass in conservatories, restoring their clarity and functionality.
Absolutely over the moon with our new windows, and the work and care that was put into installing them. This company is fantastic and worth 5 stars and more. Couldn't recommend them enough.

EXCELLENT Based on 182 reviews Posted on Maulik DarjiApril 7, 2026. Excellent service! They replaced both glass panels and fixed my door, making it feel much more secure. The team was friendly, reliable, and worked efficiently. I’m very happy with the result and would definitely recommend them.Posted on Archie TMarch 26, 2026. We had 2 doors and a flag window fitted in January '26, and the job was done to a high standard and very efficiently. Team on the job we're extremely professional and courteous. Was so pleased with the work, called them in again to fit what is the last window in need of upgrading. To say I was disappointed on the second occasion would be understating it, without going into detail as I think that would be unfair, because the way Phair Windows handled my issue was brilliant, I cannot stress enough the response was very prompt, very apologetic and completely satisfied us with the attitude and manner they handled themselves. In light of this I would not hesitate in using these guys again and recommending to anyone. Customer service outstanding, thank you. First class.Posted on Mike PookMarch 16, 2026. We needed all of the windows at our house replaced. As we were new to the area we were shooting in the dark a bit regarding the selection of a supplier but were attracted to Phair Windows due the the overwhelmingly positive reviews online. They quoted very quickly and we were pleasantly surprised at the price they offered. The work was completed to an extremely high standard and their team of installers were very helpful and took great care with their work. We’re delighted with the outcome and I have no hesitation at all in recommending them wholeheartedlyPosted on Natalia SmolikMarch 11, 2026. Phair windows ltd Tahank you so much . From the day one they been absolutely brilliant. Tom came and gave us a honest price without pushing us to buy windows form Phair windows, that was very nice as I had quotes from different companies before and they put a lot of pressure on me to buy windows from them. Then Boris send Us project proposal very quickly and we agreed fitting dates (3 days for 9 windows) . We had Lincoln & Michael fitting all windows and they been absolutely amazing , they finish everything in just 2 days ! What a amazing team 😊Posted on Ross FarrellFebruary 27, 2026. Excellent service. Polite, clean, tidy, and a very fair price. I’d recommend to a friend.Posted on George BirrellFebruary 19, 2026. Excellent work ethic, friendly and professional leadership and the work was carried out with no issues and was as expected and guaranteedPosted on Jenny RyanFebruary 6, 2026. Our fitters Michael and Lincoln were just brilliant. They worked non-stop from arrival to finish and checked with us at various stages to ensure that we were fully aware of any reasons for differences in window finishes/trims etc and fully satisfied once the work was completed. They were very patient and took time to answer all our questions fully. They tidied everything away, even sweeping the patio to ensure no bits were left behind. I hadn't heard of the company before and took a chance on them after reading their reviews. I would have no hesitation in using them again and would definitely recommend them to others.Posted on ian LeithFebruary 3, 2026. Contacted Phair Windows at the turn of the year as our " composite front door " was falling apart & couldnt open or shut very easily . Tom came out the following day , we chose the door we wanted & the fitter measured up a couple of days later . My door was fitted yesterday , the door is of a sturdier build and took both fitters to carry it , the old one was carried away by one fitter .Both of the fitters very professional , courteous & left no mess behind .... We are really pleased with our new front door . I have communicated on a regular basis with Borris and my queries have been addressed in a timely manner . I would have no hesitation in recommending this family run business to my friends & family for any future doors or windows .Posted on Suhale SweetmanJanuary 29, 2026. Brilliant service, no issues with the work, would absolutely recommendPosted on Biz BainsJanuary 27, 2026.
