Window security grilles in Dorchester

Window security grilles in Dorchester: what will it cost?

Budget £414 to £954 including VAT (£345 to £795 plus VAT) per window for window security grilles in Dorchester, supplied and fitted. Size, number of leaves, colour and access all move the price, which is fixed in writing after the survey.

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.

Getting the right window grille for your building

Colour

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

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.

What the rules say in 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.

Listed buildings and conservation areas

Listed buildings need listed building consent for works that affect their character, which can include internal grilles and their fixings. In conservation areas, councils look closely at anything fitted to the outside. We recommend speaking to the council's conservation officer before ordering.

Window security grilles in Dorchester: questions

Which areas near Dorchester do you cover?

We can arrange work in Dorchester and in nearby Weymouth (7 miles), Bridport (14 miles) and Yeovil (18 miles). Dates depend on installer availability.

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.

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.

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.
