We carry out slipped glass panel repairs in Greenwich and across the SE10 area. 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.

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 leak at the top of one pane only

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 Greenwich and nearby

Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.

London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.

From Westminster to Greenwich is roughly 6 miles — all part of the Greater London area we cover.

Neighbouring places we cover include Blackheath (1 mile), Canary Wharf (2 miles), Catford (2 miles).

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.

Slipped glass panel repairs in Greenwich: questions

Can you repair a lantern someone else installed in Greenwich?

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.

Which places near Greenwich do you cover?

As well as Greenwich, we cover nearby Blackheath, Canary Wharf, Catford, Peckham and the rest of Greater London.

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.
