Window security grilles in Chester: what will it cost?

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.

What you can specify

Quick-release escape handle for bedroom and upstairs windows
Anti-tamper fixings into masonry or a fabricated subframe
Made to measure for the reveal, including bays and splayed reveals
Fitted inside the glass by default; external options for recessed or plain openings
Works with uPVC, aluminium, timber and steel windows
Powder-coated in white, black or anthracite to sit with the frame colour

Fitting in Chester and nearby

We arrange surveys and fitting in Chester and across the CH1 postcode district, as well as in nearby Ellesmere Port (6 miles) and Halewood (12 miles). Dates depend on installer availability.

Cheshire has half-timbered and listed buildings in central Chester, Victorian terraces in Crewe and Warrington, and large modern estates across the county.

Common openings for window security grilles:

Offices and shops with side or rear windows
Rear windows facing alleys and gardens
Flats with windows onto shared walkways
Ground-floor and basement windows

Getting the right window grille for your building

Depth in the reveal

Tracks need a few centimetres of flat reveal. Where the frame sits flush with the wall, the grille can be fixed to a slim subframe instead.

Colour

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

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 Chester: questions

Do you cover Ellesmere Port as well as Chester?

Yes. As well as Chester, we can arrange surveys in nearby Ellesmere Port, Halewood and Bebington, and elsewhere in Cheshire.

Do grilles work on bay windows?

Yes. A bay is usually treated as separate grilles for each face, or one grille following the bay on a curved or angled track.

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.

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.
