What is the price of patio and bifold door security glass in Finchley?
Budget £354 to £1,074 including VAT (£295 to £895 plus VAT) per pane for patio and bifold door security glass in Finchley, supplied and fitted. Larger panes, thicker makeups and difficult access cost more; the price is fixed in writing after the survey.
Patio and bifold door security glass means fitting large sealed units with a laminated pane into sliding, French or bifolding doors. These doors are usually the biggest glass at the back of the house and out of view, so making the glass hold when it is struck closes one of the easiest routes in.

Questions we will ask at the survey
Door hardware
Glass is only part of the picture. Worn rollers, missing anti-lift blocks or old locks are often worth fixing at the same visit.
Solar control
South-facing doors can overheat. Adding solar control glass at the same time keeps rooms cooler.
Building regulations and safety in England
Planning permission
Changing the glass in an existing window or shopfront does not usually need planning permission, because the building looks much the same afterwards. A new or altered shopfront, or security features added to the outside of a building, may need planning permission from the council. Bollards or barriers on the pavement need the highway authority's consent, which is normally the council.
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.

Patio and bifold door security glass in Finchley: questions
Can you survey in Finchley and nearby towns?
Yes. Surveys in Finchley, Muswell Hill and Cricklewood are booked around installer availability.
Do you work on aluminium bifolds?
Yes, on aluminium, uPVC and timber doors, provided the frame can take the new unit thickness.
Will laminated glass make my bifolds harder to open?
Units are slightly heavier. We adjust hinges, rollers and carriages after fitting so the doors run smoothly.
Is patio door glass already safety glass?
It should be, because doors are critical locations. Most is toughened, which is safe but not secure. Adding a laminated pane makes it both.
