How much should I budget for window security grilles in Durham?

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 to think about first
Retractable, fixed or removable
Match the grille to how often the window opens. Daily-use windows suit retractable; never-opened windows suit fixed; occasional windows suit removable.
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.
Consents and safety: England
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 Durham: questions
Which towns in Durham do you cover?
We can arrange work anywhere in Durham, including Darlington, Hartlepool, Stockton-on-Tees, Durham and Chester-le-Street, and in other towns across the area.
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.
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.
Should window grilles go inside or outside?
Inside in most cases. Internal grilles avoid weathering, are harder to attack, keep the outside of the building unchanged and rarely need planning permission. External grilles suit openings with no internal depth.
