Fixed window grilles and bars in Harpenden

Fixed window grilles and bars in Harpenden: what will it cost?

As a guide, fixed window grilles and bars in Harpenden cost £234 to £714 including VAT (£195 to £595 plus VAT) per window, supplied and fitted. The exact figure depends on size, type, finish and locking, and is confirmed in writing after the free survey.

A fixed window grille is a welded steel frame of bars bolted permanently over or inside a window. It has no moving parts and no lock to pick, which makes it the simplest and most economical grille for openings that are never used for access or escape.

Finish

External grilles last longest when hot-dip galvanised and then powder-coated.

Appearance

On front elevations or period buildings a decorative or slimmer bar pattern may sit better than a plain grid.

What the rules say in England

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.

External grilles and planning

External grilles and shutters on shops and other commercial buildings normally need planning permission from the local council because they change the building's appearance. Many councils' shopfront guides favour internal, open-lattice grilles, particularly in conservation areas.

Fixed window grilles and bars in Harpenden: questions

Do you cover St Albans as well as Harpenden?

Yes. As well as Harpenden, we can arrange surveys in nearby St Albans, Luton and Hemel Hempstead, and elsewhere in Hertfordshire.

How are fixed grilles attached?

With anti-tamper bolts or resin anchors into solid masonry, or to a steel subframe where the wall is weak. Fixings are positioned so they cannot be reached from outside.

Can fixed grilles be removed later?

Yes, by unbolting them from inside, though anti-tamper fixings are deliberately awkward to remove.

Will fixed bars rust?

Galvanised and powder-coated steel is designed for years of outdoor use. Chips in the coating should be touched up to keep the protection intact.
