What is the price of window security grilles in Thornaby-on-Tees?

As a guide, window security grilles in Thornaby-on-Tees cost £414 to £954 including VAT (£345 to £795 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 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.

Fitting in Thornaby-on-Tees and nearby

Thornaby-on-Tees is about 41 miles from York, the main centre for North Yorkshire. We can survey and fit across the TS17 district and in nearby places such as Stockton-on-Tees and Billingham.

  • Outbuildings, workshops and garages with glazing
  • Offices and shops with side or rear windows
  • Rear windows facing alleys and gardens
  • Flats with windows onto shared walkways

Questions we will ask at the survey

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.

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.

Planning and safety 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 Thornaby-on-Tees: questions

Do you cover Stockton-on-Tees as well as Thornaby-on-Tees?

Yes. As well as Thornaby-on-Tees, we can arrange surveys in nearby Stockton-on-Tees, Billingham and Middlesbrough, and elsewhere in North Yorkshire.

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.

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.

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.
