What to think about first

Composite door glass

Some composite doors use a cassette made by the door's maker. We check whether a laminated version is available before quoting.

Side panels too

Side panels within 300 mm of the door are critical locations as well, and a weak side panel is an easy way in. We usually do both together.

Security rules for new homes

Approved Document Q has applied to new homes in England since 1 October 2015. Easily accessible doors and windows, meaning any part within 2 m vertically of the ground or another accessible surface, should meet PAS 24 or an equivalent, and glazing in doors and in windows within 400 mm of a door should be laminated to at least BS EN 356 P1A. It does not apply when you change the glass in an existing home, although it is a sensible benchmark.

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.

Security glass for doors in Harpenden: questions

Do you cover St Albans as well as Harpenden?

Yes. As well as Harpenden, we can arrange surveys in nearby St Albans, Luton and Hemel Hempstead. Dates depend on installer availability.

Will new door glass affect my door's warranty?

If the door is still under its maker's warranty, check their terms first. We will tell you if the door needs the maker's own glass.

Does door glass have to be safety glass?

Yes. Glass in doors up to 1,500 mm from the floor, and in side panels within 300 mm of the door edge, counts as a critical location and needs safety glass or protection.

Is toughened glass enough for a door?

It meets the safety rule but not the security need, because a broken toughened pane falls out. A laminated pane meets both.
