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 from Brixton (SW2) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- Glass edge overhanging the eaves more than its neighbours
- A leak at the top of one pane only
- A pane that looks out of line with the others
Why it happens
Missing setting blocks
Blocks under the bottom edge carry the weight of the unit; if they're missing or crushed, the unit creeps down.
Failed glass stops
Many systems use an end stop at the eaves. If it's missing or broken, nothing holds the glass in place.
About Brixton and the SW2 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.
Brixton is around 3 miles from Westminster, and both are within our Greater London coverage.
If you're just outside Brixton, we also cover Peckham (2 miles), Pimlico (2 miles), Battersea (2 miles).
How much should it cost?
Most slipped glass panel repairs jobs come in between £195 and £445 ex VAT (£234–£534 including 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.
