Door Glass Replacement in London: uPVC, Composite and Timber Doors

Door glass takes more knocks than window glass. Doors are slammed, kicked, caught by the wind and pushed by hand, so cracked, broken and misted door glass is a common call. The glass can almost always be replaced without replacing the door. Mark replaces glass in uPVC, composite, timber and aluminium doors, including internal glass doors, and matches obscure and decorative patterns where possible.

How the glass comes out depends on the door. In a uPVC door the glass or sealed unit sits behind beads that unclip from the inside, much like a window. In a composite door it usually sits in a cassette fixed to the slab from both sides. In a timber door it may be held by beads or putty, and an aluminium door uses gaskets and beads. Mark works out the fixing first, so the glass is replaced without damaging the door.

Glass in and around doors generally has to be safety glass, either toughened or laminated, because it is in a place where people can fall against it or push it by hand. That applies to the door itself and to low side panels next to it. Our guide on where safety glass is required at home explains the rule in plain terms. If your old door glass was plain annealed glass, the replacement is specified as safety glass.

Obscure and decorative glass is common in front and back doors, where you want light without being seen. There are many patterns, some long discontinued. Send a photo and Mark will look for a match; where the original pattern isn't made any more, a close modern equivalent or a plain obscure glass can be fitted. If only one pane of a double glazed door panel is cracked, the whole sealed unit is replaced.

If the glass has broken and the door can't be secured, it can be boarded or temporarily glazed to make it safe, subject to availability, then glazed properly once the new glass is ready. For cracked glass in windows rather than doors, see our cracked glass replacement page; for bifold door panels there is a separate guide.

Misted glass is a different fault from broken glass but is fixed in a similar way. If a double glazed panel in your door has gone cloudy between the panes, the seal has failed and the unit is replaced; the door, handles and lock are not touched. While the glass is out, it is a chance to change the specification, for example to an obscure pattern for privacy or a toughened or laminated pane where the old one was not safety glass.

How the repair works

1. 1. Photo of the glass A photo of the door and the glass pattern helps Mark identify the fixing and match the glass.
2. 2. Measure and price The panel is measured and a fixed price confirmed before any work starts.
3. 3. Glaze and tidy New glass fitted and beaded, the door tested, and the old glass taken away.
