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.

Stevenage homes, and what to check first.
The homes. Stevenage was the first post-war new town, designated in 1946. Most homes are in its planned neighbourhoods from the 1950s onwards, with the older High Street in the Old Town.
What that means. Many new town houses still have first-generation replacement windows now reaching the end of their life. They share a small number of designs, which makes a whole-house replacement easy to plan.
Check first. Flats and maisonettes are common in the neighbourhoods, and for those the freeholder usually has to agree before anything is ordered.

Opening times and directionsYour questions
Buying French casement windows in Stevenage.
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 Stevenage?
Yes. We cover Stevenage and its SG1 and SG2 postcodes from our Milton Keynes base, and everyone who surveys and fits works for us. Nearby, we also fit French casement windows in Hitchin, Letchworth and Luton.
Do I need permission to replace windows in Stevenage?
Stevenage is covered by Stevenage Borough Council. Like-for-like replacements are usually permitted development; the Old Town conservation area and listed buildings need more care, and flats need the freeholder's agreement.

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.
