FAQs About Double Glazed Home Extensions

In most cases, planning permission is NOT necessary for all conservatories, but we always recommend that you check whether planning permission is required. Most conservatories can be built under the “permitted development” rules, but this is subject to certain conditions. Checking this will give you peace of mind and there’s also no risk of having your conservatory removed in the future if it is built illegally.

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!
