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 Whitehaven (CA28) 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.
Failed glass stops
Many systems use an end stop at the eaves. If it's missing or broken, nothing holds the glass in place.

Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.

Guide prices for slipped glass panel repairs in Whitehaven
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.

Slipped glass panel repairs in Whitehaven: questions
How do I get a price for slipped glass panel repairs in Whitehaven?
Send a few photos of the lantern and the problem, with your Whitehaven postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.
Can you repair a lantern someone else installed in Whitehaven?
Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.
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.
