Retractable security grilles in Grantham

What is the price of retractable security grilles in Grantham?

Most retractable security grilles in Grantham fall within £414 to £1,554 including VAT (£345 to £1,295 plus VAT) per opening for supply and fitting. We confirm a fixed price in writing after a free survey, before anything is ordered.

A retractable security grille is a steel or aluminium lattice of vertical bars joined by scissor links that runs in a top and bottom track. Drawn across a window or door it forms a locked barrier; slid back, it folds into a narrow stack at the side so the opening is fully usable.

Lincolnshire combines the historic hilltop core of Lincoln with Grimsby and Scunthorpe's industrial terraces and many small market and coastal towns.

This type of grille suits:

Office receptions and glazed partitions
Back doors, French doors and patio doors
Ground-floor windows of homes and flats
Stockrooms and cash offices

Questions we will ask at the survey

Bottom track or no bottom track

A bottom track gives the most rigid grille but can be a trip point across a doorway. Low-profile and removable floor tracks are available for doors.

Which side it folds to

The stack needs a clear wall or reveal to park against. We check curtains, handles, radiators and light switches before the grille is ordered.

Planning and safety 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.

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.

Retractable security grilles in Grantham: questions

Do you cover Sleaford as well as Grantham?

Yes. As well as Grantham, we can arrange surveys in nearby Sleaford, Newark-on-Trent and Melton Mowbray, and elsewhere in Lincolnshire.

Will a grille stop me opening my windows?

No. An internal grille sits inside the reveal, so you can open the window as normal when the grille is folded back, and usually with it closed if there is enough depth between grille and glass.

Can a retractable grille be fitted inside the window?

Yes, and that is how most are fitted. The tracks fix into the window reveal or to a timber or steel subframe, so the grille sits between the glass and the room.

Do retractable grilles need a bottom track?

Most do, because the bottom track stops the grille being pushed out of line. On doorways a low or recessed track can be used to reduce the trip hazard, and some top-hung designs work without one on smaller openings.
