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 Islington (N1) and we'll tell you which it is — with the price agreed in writing before any work.
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 pane that looks out of line with the others
Common causes we find
Missing setting blocks
Blocks under the bottom edge carry the weight of the unit; if they're missing or crushed, the unit creeps down.
Loose cappings
If the capping no longer clamps the glass firmly, the unit can creep with thermal movement.
About Islington and the N1 area
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
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.
Islington is around 3 miles from Westminster, and both are within our Greater London coverage.
If you're just outside Islington, we also cover Highbury (1 mile), Holloway (1 mile), Camden Town (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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.

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.
