Choosing uPVC doors

Balance daylight, privacy and access.

Glass and panels

Choose the balance of solid panel and glazing, then decide where obscured glass would be useful. Photographs help us match the existing opening.

Finish and threshold

Dunstable

Dunstable homes, and what to check first.

The homes. Dunstable grew where Watling Street crosses the Icknield Way. There are older buildings around the Priory Church and the centre, but most homes are interwar and post-war, below Dunstable Downs.

What that means. Most Dunstable homes are straight replacements, where the decisions are glass, colour and whether to change the opening style. Older properties near the centre need more care.

Check first. Houses from the interwar years sometimes still have steel or timber windows. When they come out, the surrounding brickwork and lintels need checking before the new frames go in.

Can a new uPVC door match my existing windows?

We can compare the available colours and foils with your existing frames using samples. Send photographs of the door and nearby windows when you enquire.

How do I get a price for uPVC doors?

Silvia Peraro a month ago

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.
