Orangery lanterns are larger and often sit within a perimeter roof with internal gutters, so leaks can come from the lantern, the perimeter roof or the junction between them. Send photos from Carshalton (SM5) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- Leaks at the lantern edge or around the internal pelmet
- Staining on the orangery ceiling
- Rotten or flaking timber on the lantern
What usually causes it?
Large-span movement
Bigger lanterns move more, stressing seals.
Timber maintenance
Painted timber orangeries need regular redecoration.
Roof lanterns in Carshalton
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.

What should you expect to pay in Carshalton?
Most orangery lantern repairs jobs come in between £395 and £2,495 ex VAT (£474–£2,994 including VAT), per lantern. 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.
