Retractable security grilles in Derry

What is the price of retractable security grilles in Derry?

Budget £414 to £1,554 including VAT (£345 to £1,295 plus VAT) per opening for retractable security grilles in Derry, supplied and fitted. Size, number of leaves, colour and access all move the price, which is fixed in writing after the survey.

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.

Questions we will ask at the survey

Inside or outside the glass

Inside is the norm: it is protected from weather, keeps the street view unchanged and usually avoids planning issues. Outside fitting suits recessed doorways and openings with no internal depth.

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.

Listed buildings and conservation areas

Listed buildings in Northern Ireland need listed building consent for works affecting their character, with the council deciding and the Department for Communities' Historic Environment Division advising. Conservation areas bring extra scrutiny of external changes.

Grilles inside the glass

A grille fitted inside the glass does not normally need planning permission in Northern Ireland, as it does not materially change the outside of the building. If the building is listed, listed building consent may still be needed.

Retractable security grilles in Derry: questions

Do you cover Strabane as well as Derry?

Yes. As well as Derry, we can arrange surveys in nearby Strabane, Limavady and Coleraine, and elsewhere in County Londonderry.

How long does a retractable grille take to fit?

Most single windows or doors are fitted in an hour or two once the made-to-measure grille arrives. A shopfront or several openings may take a day.

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.

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.
