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 Denton (M34) 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
What usually causes it?
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.
Covering Denton and nearby
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
Urban grime and traffic film dull glass and frames quickly; a clean and seal check makes a tired lantern look and perform much better.

What should you expect to pay in Denton?
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?
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.
