In Surbiton, 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.

Signs you need 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
What usually causes it?
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.
Covering Surbiton and nearby
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.
Across London, many lanterns sit on rear extensions with access only through the house, so we protect floors and plan the work to keep time indoors to a minimum. Parking and any permits are factored into the quote.
From Westminster to Surbiton is roughly 10 miles — all part of the Greater London area we cover.
We also cover nearby New Malden (2 miles), Esher (3 miles), Hampton (3 miles).
How much should it cost?
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?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.
