Window security grilles in Sleaford

What is the price of window security grilles in Sleaford?

Most window security grilles in Sleaford fall within £414 to £954 including VAT (£345 to £795 plus VAT) per window for supply and fitting. We confirm a fixed price in writing after a free survey, before anything is ordered.

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.

Works with uPVC, aluminium, timber and steel windows
Lock positioned to clear window handles and restrictors

Fitting in Sleaford and nearby

Surveys in Sleaford (NG34) are booked around installer availability. We also cover nearby Grantham (11 miles), Boston (16 miles) and Lincoln (17 miles).

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:

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

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.

Escape requirements

If the window is a designated escape window, the grille must open from inside without a key or tool. We fit quick-release locks for these.

Planning and safety in England

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.

Grilles in rented homes

Landlords in England must keep rented homes free from serious hazards under the Housing Health and Safety Rating System, which includes fire. A grille that stops a tenant using an escape window can create a hazard, so grilles in rented homes should have keyless internal releases.

Window security grilles in Sleaford: questions

Do you cover Grantham as well as Sleaford?

Yes. As well as Sleaford, we can arrange surveys in nearby Grantham, Boston and Lincoln, and elsewhere in Lincolnshire.

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.

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.

Are window grilles safe in a bedroom?

They can be, provided the grille has a release that opens from inside without a key. Bedroom and upstairs windows often have to serve as escape routes, so we will not fit a key-only grille over a window you need for escape.
