French door grilles in Blackburn: what will it cost?
As a guide, French door grilles in Blackburn cost £954 to £2,034 including VAT (£795 to £1,695 plus VAT) per pair of doors, supplied and fitted. The exact figure depends on size, type, finish and locking, and is confirmed in writing after the free survey.
French door grilles are usually a pair of retractable grilles that fold to each side of the doors and meet in the centre, where they lock together. They protect the glazing and the meeting stiles, which are the weak point of many French doors.

- Small stacks at each side of the doors
- Pair of leaves meeting at a central lock
- Optional shoot bolts top and bottom
- Each side opens independently
- Low-profile floor track

Getting the right French door grille for your building
Curtains and blinds
Stack positions are planned around curtain tracks and returns.
One side or both
A centre-meeting pair lets you open one side for everyday use.
What the rules say in England
Bedroom and escape windows
Approved Document B (fire safety) expects many habitable rooms in houses, especially first-floor rooms, to have an emergency escape window with an unobstructed opening of at least 0.33 m², at least 450 mm high and 450 mm wide, with the bottom of the opening no more than 1,100 mm above the floor. We only fit grilles over escape windows with a release that opens from inside without a key.
Grilles inside the glass
A grille fitted inside the glass does not normally need planning permission, because it does not materially change how the building looks from outside. If the building is listed, listed building consent may still be needed.

French door grilles in Blackburn: questions
Do you cover Darwen as well as Blackburn?
Yes. As well as Blackburn, we can arrange surveys in nearby Darwen, Accrington and Chorley, and elsewhere in Lancashire.
Do French door grilles need a floor track?
Usually a low-profile one, which keeps the grille rigid and is easy to step over.
Can French door grilles open one side only?
Yes. Each leaf runs independently, so you can open one side and leave the other closed.
Will the grille match my doors?
We powder-coat grilles in white, black, anthracite or a RAL colour close to your frames.
