Window security grilles in Nailsea

Window security grilles in Nailsea: what will it cost?

Most window security grilles in Nailsea fall within £414 to £954 including VAT (£345 to £795 plus VAT) per window for supply and fitting. We confirm a fixed price in writing after a free survey, before anything is ordered.

A window security grille is a steel barrier fitted across a window so that breaking the glass no longer gives a way in. It can be retractable, fixed or removable, and is most often fitted inside the reveal where it is protected and barely noticed from outside.

Anti-tamper fixings into masonry or a fabricated subframe

Getting the right window grille for your building

Colour

White disappears against white frames, while black or anthracite suits darker frames and period sash windows.

Escape requirements

If the window is a designated escape window, the grille must open from inside without a key or tool. We fit quick-release locks for these.

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.

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.

Window security grilles in Nailsea: questions

Do you cover Portishead as well as Nailsea?

Yes. As well as Nailsea, we can arrange surveys in nearby Portishead, Clevedon and Bristol, and elsewhere in Somerset.

Will a grille damage my window frame?

No. Grilles fix to the wall reveal or a subframe, not to the window itself, so the frame and its warranty are unaffected.

Are window grilles safe in a bedroom?

They can be, provided the grille has a release that opens from inside without a key. Bedroom and upstairs windows often have to serve as escape routes, so we will not fit a key-only grille over a window you need for escape.

Can I still open the window with a grille fitted?

With a retractable or removable grille, yes. Many fixed internal grilles also leave room to open the sash or casement behind them.
