The installation was absolutely perfect with extraordinary attention to every detail from ground upwards.

You might also be wondering...

Q: Will the finish on uPVC windows degrade over time?

A: We guarantee that uPVC won’t rot, rust, peel or flake and also offer industry leading guarantees on many other aspects of the window for added peace of mind.

Q: Do uPVC windows look cheap?

A: They look smooth and clean and depending on the surrounding materials of the home can actually look quite stunning. We don’t believe the windows would be so popular if people did find them cheap and so we’re not surprised they continue to be a best seller.

Q: Is the supply and installation of uPVC windows quicker due to their popularity?

A: Every single job is different from start to finish, meaning they each have their own challenges and demands. Everest does not operate with a factory-line mentality and so never hurry the installation process. As all of our products are made-to-measure for a perfect fit, the timing of the process is ordinarily the same.

Q: How convincing is wood effect finish on uPVC?

A: We are proud to say that it really does look like natural timber, but it comes with all of the modern benefits of a uPVC window, so it is finally possible to get a window that offers traditional looks with the convenience of a modern product.

Don't forget the Everest Price Promise

If within seven days of placing your order, you find a lower price for products designed, made and installed to the same specifications and with the same guarantees, Everest will refund the difference.
