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.

Aylesbury homes, and what to check first.
The homes. Aylesbury has a medieval old town around St Mary's church, Victorian and interwar streets around the centre, large post-war estates, and new neighbourhoods such as Berryfields and Kingsbrook.
What that means. Much of Aylesbury is interwar and post-war housing, where the choice is glass, colour and opening style. The old town and the newest estates each need their own checks.
Check first. The old town is a conservation area. On the newest estates, check your deeds and builder's warranty before changing the front of the house.

Buying double glazing in Aylesbury.
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 Aylesbury?
Yes. We cover Aylesbury and its HP19, HP20, HP21 and HP22 postcodes from our Milton Keynes base, and everyone who surveys and fits works for us. Nearby, we also fit double glazing in Leighton Buzzard, Buckingham and Dunstable.
Do I need permission to replace windows and doors in Aylesbury?
Aylesbury is covered by Buckinghamshire Council. Like-for-like replacements are usually permitted development, but the old town is a conservation area with many listed buildings, and newer estates can carry planning conditions or covenants.
What our customers say.
Real reviews from real installations. Every one is public, so you can go and check them yourself.
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.
