Fantastic company. We needed all our windows in our house replacing and after been let down multiple times by another company, we called up Phair Windows. We were given a quick, no nonsense quote on the day. The communication was fantastic all the way throughout the whole process. On the day of the fitting, we had the loveliest bunch of guys turn up and got the job done with such efficiency and care. Once they were fitted, they ran through all the work they had done and gave a complete run down of everything. Absolutely over the moon with our new windows, and the work and care that was put into installing them. Honestly, thank you all so much. This company is fantastic and worth 5 stars and more. Couldn't recommend them enough. Big thank you to all the guys who installed them on the day (21/07/22).

Love love this company. The guy who turned up to quote gave me a no nonsense competitive quote. He was friendly and helpful and put covers on his shoes when entering. Fast forward 1 week. He was prompt, quick and efficient on the installation. Will be rebooking him soon to do another window and will happily recommend.

We called Phair windows to fix a small window opening that was stuck. After trying to figure it out myself, I was unsuccessful and gave up. A gentleman called Jake came, he looked at the problem and fixed it within minutes. He was very friendly, polite and professional. I'd definitely recommend them for any of your window needs.

We needed repairs on two of our window handles and mechanisms. They came over on time and charged a very fair price. The quality of their work was great and we’d most definitely recommend their service. Thank you!

Frequently Asked Double Glazing uPVC & Sash Window Questions

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. 

uPVC window frames are very low maintenance and won’t rust or rot. However, dirt will build up over time, so they’ll regularly need wiping down. A sponge and a bucket of warm soapy water with washing up liquid works wonders on window panes. Or, mix one part of white vinegar with four parts of warm water into a spray bottle and spray onto the frames. Leave it for 10 minutes and wipe the grime away with a soft cloth – avoid scouring pads as this can remove the glossy finish.

uPVC windows are incredibly safe, secure and virtually impossible to break into. They provide outstanding performance and durability, are incredibly low maintenance and thermally efficient.

Triple glazing is 3 panes of glass instead of 1 or 2, and can help trap even more heat in your home (especially if the room is dark, cold and North facing), are a wise choice for noisy surroundings, and more secure. However, triple glazing is much more expensive than double glazing and generally, is not worth the extra cost when compared with our high-performance A++ rated double glazing. Double glazing is the most popular choice due to its all round performance, but it’s worth speaking to one of our experts if you’re unsure on what’s best for your home.

Yes, grey and coloured uPVC windows are generally 10% more expensive than white uPVC windows.
