Roof glazing, blinds, roofline and repairs
Roof glazing, blinds sealed inside the glass, the boards around the roof edge, and the smaller jobs. Some of this we do on its own, and some of it makes sense to do while the scaffolding is already up.

Most of these are smaller jobs than people expect.
A misted window does not mean new windows, and a cold room does not always mean the frames are at fault. It is worth working out which of these three you actually have before anyone quotes you for a whole house.

Before you ask
The questions we get asked on the phone.
If you want a figure before you speak to anyone: Window and door prices Double glazing costs
My windows are misted. Do I need new windows?
Usually not. A misted pane means the seal on that unit has failed, not that the frame has. If the frames are sound we change the glass and leave everything else alone.
Do you work on windows you did not fit?
Yes. Handles, hinges, locks and replacement glass on installations that were never ours are a normal part of the week.
Will secondary glazing help with traffic noise?
It is the better answer than new windows where the existing frontage has to stay, because the gap between the two panes is doing the work. On a listed elevation it is often the only answer.
Roof lantern or flat rooflight?
A lantern stands proud of the roof and throws light further into the room. A flat rooflight sits close to the roof line, which suits a low extension or anywhere a lantern would look too tall from the garden.

Fenster have just completed a front door installation on my new property - fantastic job and strongly recommend! The online design tool is great, Perry back at HQ is brilliant as is his communication. Andy, who installed the door, is a top gent and professional. Will definitely be a returning customer.

Really happy with the service we received from Fensters Windows. Aaron and Shane turned up on time and were both really friendly. They explained any issues as they went along and talked us through the different options, which we really appreciated. They did a great job fitting our new back doors and cleaned up everything afterwards. We also paid exactly what we had originally been quoted, with no unexpected extra costs. Really pleased with our new doors and would definitely recommend Fensters Windows. Thank you Aaron and Shane!

We have used Fensters for years on a variety of glazing work, and 2 door installations. They are competitively priced and responsive. They take great care over measuring and specifying the work, giving you a clear quote so you understand what you are getting (thanks Perry!). The fitters are all extremely competent and personable. We had to replace our front door for accessibility reasons, they gave us confidence that our requirements would be met, reproduced the intricate leaded and stained-glass pattern of our old door, and did a quality fitting job (thanks to Johnnie and Shane!). In summary they are our go-to suppliers for all replacement and repair work.

I had an excellent experience with Fenster Glazing from start to finish. Nick Perry and David managed the initial quote to installation process seamlessly, keeping communication clear, honest, and completely stress-free. When it came to the actual fitting, Zac and Shane did a fantastic job with the installation, working efficiently and leaving everything spotless. The professionalism from the entire team was top-notch, and the final result looks brilliant. I highly recommend them.

Great service from Fenster Glazing, very happy with our new bi-fold door, glass door and windows (with built-in blinds) There was an issue with the wrong spec of glass provided to them from their supplier, so they had to temporarily board up a door and a window, but this was put right within a few weeks. Recommended, thanks.
