FAQs About Cheap uPVC Windows Leicestershire

Our high-quality and professionally installed uPVC windows from Phair Windows & Glass are guaranteed for 10 years but they can last more than 20 years. Signs that they may need replacing are draughts, visible damage, water leakage, or they are difficult to open, close and lock, or are sticking. You may also wish to replace your old windows to save money on your energy bills, improve security, prevent draughts, and stop any noise pollution

uPVC windows need replacing approximately every 20 years, but some windows may last 10-35 years depending on the quality and upkeep. Windows installed around 2000 will likely need replacing now. 

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. At Phair Windows & Glass we offer the highest uPVC window security available. 

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.

Professional, skilled, great communication from the on-site team - honestly, the best workmen I’ve ever had. They left the place tidy and neat. Thanks guys! They did a great job on a dreary, winter’s day with a smile. I love the new porch, which was a decent price. Honestly though, the sales guy Tom and the crew of Cal, Jake and Aaron were great. After having had a bad experience before with a different company, I’ll be using Phair Windows to replace my windows in the near future as well.

Absolutely amazing job from everyone. Getting the quote from Tom was very easy, fast, very clear and informative and good price. The process was very easy and adjustable to my hours. I got fitted a bathroom and a bedroom window and the guys were very friendly, professional, hard worker and i was very impressed with how clean they were. They brought their own vacuum cleaner, did the job, and when they left it looked like they weren't even there. Absolutely recommend, and will be back again for more windows.

After experiencing an absolute nightmare with a claim put in to Aviva insurance, I found Phair Windows and Tom. As I live in Kent and my elderly parents in Leicester Tom had to navigate all of us. From the very beginning I told him a price and a vision. He delivered exactly what my parents wanted, in exactly the time frame he had given and bang on budget, even with slight changes from mum along the way. The workmen had total respect for my elderly parents and the disruption was a minimum. Thank you Tom and all your chap's who delivered a first class porch at a reasonable cost.

Phair windows & Glass fitted us some new French doors. They were prompt, friendly, and respectful of our property. Tom gave us the best price, cheaper than other companies. There was no messing about. We gave a deposit and they came on the date they said. We will use them again in the future. They have done a lovely job.

The initial visit from Tom gave a good impression of the company - a friendly clear, up-front quote for the work needed. We appreciated this straightforward, honest approach. The follow up visit with the surveyor was arranged easily and again was straightforward. The fitting was conducted by Jason, Angus, Jake and Arron. Professional, friendly, and hardworking- a credit to any company. They worked hard throughout the day, and we were able to just leave them to get on with the job. They ensured we were happy before they left and in addition left everything clean and tidy removing all the waste. Our conservatory looks fantastic, and the materials used are of a high quality. Would highly recommend. Reasonable price too. Thank you!
