Skylight repair in London, for leaking, misted and broken roof glazing.
Skylight & rooflight repairs
A skylight is the one window you cannot easily reach and the one most exposed to the weather. When it starts to leak, mist up, crack or stops opening, call a glazier rather than a roofer first: most skylight faults are in the glass, the seals or the hardware, and can be fixed without replacing the whole unit. Glazing London repairs skylights, rooflights and pitched roof windows across Central and North London. Call 07915 903485 or send a photo.
Common faults
What goes wrong with skylights
- Misted sealed units, where the seal between the panes has failed
- Cracked glass from impact, frost or a falling branch
- Leaks around the frame from failed seals or flashing
- Hinges, gas struts and winders on opening roof windows that have worn or broken
- Blinds and fittings damaged by condensation
- Flat rooflights on extensions with failed upstand seals
How we repair them
Glass, seals and hardware
- New glass: misted or cracked units replaced in the existing frame with toughened or laminated safety glass made to measure, the right choice overhead.
- Seals and leaks: perimeter seals renewed and leak paths traced, so water is stopped at the source.
- Hardware: hinges, gas struts and winders on Velux-style roof windows replaced so they open and close properly.
- Make safe first: a cracked skylight is made safe and weather-tight the same day if needed, then reglazed.
Need a new rooflight instead? See rooflights and skylights and roof lanterns. Misted glass elsewhere in the house is covered on misted double glazing repair, and other faults on our window and door repairs page.
Skylight repair questions
My skylight is leaking. Is it the glass or the roof?
It can be either. Water often gets in through failed flashing or seals around the frame rather than the glass itself, and condensation running off cold glass can look like a leak. We check the glass, seals and flashing, and tell you which it is before quoting.
Can you replace misted glass in a skylight without a new skylight?
Usually, yes. A misted or cracked sealed unit in a roof window or rooflight can often be replaced in the existing frame with a new unit made to measure in toughened or laminated safety glass.
My roof window will not open or stay open. Can that be fixed?
Yes. Worn hinges and failed gas struts or winders are common, and are replaced so the window opens, stays open and closes properly again.
Is a cracked skylight an emergency?
If the glass is cracked right through, rain is getting in, or pieces could fall into the room, yes. Keep people out from under it and call us. We can make it safe and weather-tight, then replace the glass.
Do you fit new rooflights if mine cannot be repaired?
Yes. See our rooflights and skylights page for new flat roof lights, opening rooflights and walk-on glass.
