In Sutton, as everywhere, a slipped panel is a glass unit that has slid down its glazing bars, leaving a gap at the top and often pushing past the eaves at the bottom. Send photos and we'll tell you what we think has failed.

Is it time for slipped glass panel repairs?
- A visible gap under the capping at the top of a pane
- Glass edge overhanging the eaves more than its neighbours
- A leak at the top of one pane only
Why it happens
Failed glass stops
Many systems use an end stop at the eaves. If it's missing or broken, nothing holds the glass in place.
Loose cappings
If the capping no longer clamps the glass firmly, the unit can creep with thermal movement.
About Sutton and the SM1 area
Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.
We cover Sutton as part of Greater London, about 11 miles from Westminster.

What should you expect to pay in Sutton?
Typical range: £195–£445 ex VAT, which is £234–£534 with VAT, per panel. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in England?
In England, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010, so we set out the route in writing first. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.

Slipped glass panel repairs in Sutton: questions
How do I get a price for slipped glass panel repairs in Sutton?
Send a few photos of the lantern and the problem, with your Sutton postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.
Which places near Sutton do you cover?
As well as Sutton, we cover nearby Carshalton, Banstead, Ewell, Wallington and the rest of Greater London.
Can a slipped panel be pushed back up?
Not safely without removing the capping. The fix is to support the unit properly so it can't slip again.
Does a slipped panel mean my lantern was badly fitted?
Not necessarily — blocks can crush and stops can break over time — but if the lantern is new, talk to the installer first as it may be under warranty.
