What needs replacing?
Start with what you want to change.
New windows
Choose how each room opens and ventilates first. Casement, flush and sliding sash windows offer different frame lines and opening styles; uPVC and aluminium give you different finishes.
View new windowsNew doors
A front entrance needs a different layout from a wide garden opening. Compare composite entrance doors, paired French doors, bifolds and sliding doors around the space you use.

If your frames are sound and the glass has misted between the panes, we can assess the sealed units on their own. Send a photograph of the whole window and a close-up of the glass.

Luton homes, and what to check first.
The homes. Luton's older streets grew with the hat trade, with Victorian terraces around High Town and the centre, then large interwar and post-war estates across the rest of the town.
What that means. Terraced houses here often have narrow frontages where the proportions of the windows matter. The interwar and post-war estates are usually straight replacements.
Check first. Plaiters Lea, the old hat district, is a conservation area. In the older streets near the centre, check before changing the front of the house.

Your questions
Buying double glazing in Luton.
Product choices, pricing and what happens before we fit.
Can you replace the glass and keep my existing frames?
We can replace sealed glass units in suitable existing frames. Send us photographs and approximate sizes so we can check the frame condition and identify the glass. For handles, hinges or locks, our repairs team can advise separately.
How do I get a price for double glazing?
Build your price online using approximate sizes, or book a free consultation and we price the job with you. Both use the same software and price list. Once you decide to go ahead, a technical survey confirms the measurements and fitting details before anything is made.
Do you supply and fit in Luton?
Yes. We cover Luton and its LU1, LU2, LU3 and LU4 postcodes from our Milton Keynes base, and everyone who surveys and fits works for us. Nearby, we also fit double glazing in Dunstable, Toddington and Hitchin.
Do I need permission to replace windows and doors in Luton?
Luton is covered by Luton Borough Council. Like-for-like replacements are usually permitted development, but check first if your house is listed or in a conservation area such as Plaiters Lea.
What our customers say.
Real reviews from real installations. Every one is public, so you can go and check them yourself.
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!
