Security window film in Finchley: what will it cost?
Budget £54 to £132 including VAT (£45 to £110 plus VAT) per m² for security window film in Finchley, supplied and fitted. Larger panes, thicker makeups and difficult access cost more; the price is fixed in writing after the survey.
Security window film is a clear, tough polyester film bonded to the inside face of existing glass with a strong adhesive. When the glass breaks, the film holds the fragments together, which reduces injury from flying glass and slows down anyone trying to get through, without replacing the glass itself.

Getting the right glass for your building
Is the glass suitable
Some double-glazed units and coated or tinted glass can suffer heat stress with certain films. We check the glass and the unit maker's guidance first.
Daylight application or anchored
A film applied to the visible glass is quickest. Anchoring it to the frame holds the whole pane in place and is the choice for blast mitigation.
What the rules say in England
Replacing glass in an existing frame
Replacing only the glass or sealed unit in an existing frame is generally treated as a repair in England rather than notifiable building work. Replacing a whole window or door is notifiable and is normally certified through a competent person scheme or approved by building control. Either way, new glass in a critical location should still be safety glass.
Listed buildings and conservation areas
In England, listed building consent from the council may be needed to replace historic glass such as crown or cylinder glass, or to alter glazing bars, sashes and frames. Historic England publishes guidance on traditional windows. Secondary glazing and window film are often easier to agree because they can be removed later, but the council's conservation officer makes the decision.

Security window film in Finchley: questions
Do you cover Muswell Hill as well as Finchley?
Yes. As well as Finchley, we can arrange surveys in nearby Muswell Hill, Cricklewood and Kilburn. Dates depend on installer availability.
Can film be used on listed buildings?
Film is fitted inside and can be removed, so it is often an acceptable way to protect historic glass. Check with the council's conservation officer for listed buildings.
Does security film make glass as strong as laminated glass?
Not usually. Film greatly improves how glass breaks and slows an attack, but it only matches a laminated glass class where that film and glass combination has been tested together.
How long does window film last?
Fitted on the inside, quality films typically last many years. Life depends on sun exposure and cleaning, and we give the manufacturer's expected life with the quote.
