FAQs About Windows
What window colour options do you offer?
We offer an extensive range of 44 beautiful colour finishes for our uPVC windows. While classic white remains popular, more homeowners are choosing coloured uPVC.
These colours, known as uPVC foils, are applied during extrusion and are available in two distinct finishes: a fine textured “painted wood” finish and a smooth finish. We recommend obtaining a sample to help you choose the perfect match for your home.
You can have the coloured foil applied to both sides of your window profiles, though a classic white interior is the most commonly requested finish.
Our range includes colours to suit any home’s character, such as the rustic appeal of Golden Oak, the sophisticated tones of Dark Rosewood and Walnut, or the contemporary feel of Agate and Anthracite Grey.
We can also offer colour finishes in any RAL colour upon request. Please contact us for a quote.
How much do replacement windows cost?
There are many factors that come into play when buying new windows. The average cost for new windows can be anything from £500 to £3,200 depending on the different variables such as window type, frame style, double glazing, colour (we offer a range such as wood-grain, anthracite grey or white), number of windows and the size.
Should I replace all my windows at once?
If your windows were installed more than 20 years ago then it’s best to have all of your windows replaced. After 20 years is generally when you start to see problems and they will not be as thermal efficient as they used to be. Replacing your windows is a huge investment so therefore, replacing the worst windows could be an option. However, replacing all of your windows at once will save you money in the long term. Our expert installation team can complete the full job in a couple of days.
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.
Is triple glazing better than double glazing?
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 glazed windows are 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.
Are anthracite grey uPVC windows more expensive than white?
Yes, grey and coloured uPVC windows are generally 10% more expensive than white uPVC windows.

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.
