Choosing French casement windows
Two opening sashes, one clear opening.
The opening
The centre section travels with one sash when both sides open. We check the usable aperture and the space outside for the sashes to swing.

Handle positions and the order in which the sashes open affect daily use. Try the mechanism and explain how you want to ventilate the room.

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 French casement windows in Aylesbury.
Product choices, pricing and what happens before we fit.
Is French casement a material or a window layout?
It is a layout: two side-hung sashes open without a fixed centre mullion remaining in the aperture. We offer this arrangement in compatible uPVC and aluminium systems; the main configuration page shows the choices.
How do I get a price for French casement windows?
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 French casement windows in Leighton Buzzard, Buckingham and Dunstable.
Do I need permission to replace windows 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.

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.
