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 Thetford (IP24) 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
- A leak at the top of one pane only
- A pane that looks out of line with the others
Common causes we find
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 Thetford and nearby
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.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.

What should you expect to pay in Thetford?
Guide price for slipped glass panel repairs: £195–£445 ex VAT (£234–£534 inc 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.

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.
