Maintaining Safestyle double glazing windows

Safestyle claims minimal maintenance is required, but in order to avoid damage to your windows, you should follow the maintenance instructions:

If condensation forms on the internal side of the window unit, don’t be alarmed. You can resolve this by increasing ventilation inside your home or using a dehumidifier. However, if condensation appears between the glass panes, it is likely your window seal is blown and needs replacing. You should therefore check your guarantee document to see if Safestyle will accommodate this.

What the experts say

Here’s what the experts said about Safestyle and its products:

“It’s a great option for buyers that need to make a big purchase on credit or want to lower the carbon footprint of their home renovations through recycling.”Federation of Master Builders

“Safestyle is one of the largest double glazing installers in the UK because they offer high-quality doors and windows, a price-match guarantee, and good regular pricing. However, it is important that you know what you need so you can get a good deal on your installation.”

“Safestyle UK is a strong option when it comes to companies. Its solid reputation and good reviews speak volumes.”The Eco Experts

Customer reviews

Safestyle achieved a great score of 4.1/5 on Trustpilot (based on over 38,000 reviews) and 4.5/5 on Review Centre (based on over 11,000 reviews), with most clients loving the product, quality, and service. Most negative reviews were based on the sales and installation teams.

“From the first sales meeting all through to the fitting of 18 windows and two doors, the Safestyle team has made this a stress-free experience for me. Daz and his team were fantastic.”—Pauline Owen via Trustpilot

“A good experience throughout, from ordering to the work being done—and not much mess afterwards. The only annoying thing was being asked three times in less than 24 hours about having the other windows and doors done. We explained each time that we can’t afford at the moment and need time to save up as these aren’t as urgent to get done. We will be in touch when we have saved up.”—Lee via Trustpilot

“I got six windows fitted to replace the old leaking ones, and six years later they are still like the first day. [The fitters] came, fitted, and cleaned up all in a few hours’ work. I highly recommend [them].”—O’Neal75 via Review Centre

Our recommendation

With their state-of-the-art production facility, flexible payment plans, price guarantees, and recycling programme, Safestyle is a great option for customers concerned with cost, quality, and environmental impact.

However, we advise that you have a clear vision of what you want before contacting Safestyle so you have an idea of what the quote should include. It’s also a good idea to arrange to inspect the local installation team’s recently completed projects, to ensure quality workmanship.
