In Harlow, as everywhere, 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 and we'll tell you what we think has failed.

Roof lantern glass panel slipped down past the eaves leaving a gap beneath the glazing bar

What you might be seeing

  • 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.

Covering Harlow and nearby

Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.

From Chelmsford to Harlow is roughly 16 miles — all part of the Essex area we cover.

How much should it cost?

Guide price, per panel£195–£445 ex VAT£234–£534 inc VAT

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?

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.

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.

What does resetting a slipped panel cost?

Usually £195–£445 ex VAT per panel, confirmed in writing before work starts. If the unit is damaged it may need replacing.

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.
