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 New Malden (KT3) and we'll tell you which it is — with the price agreed in writing before any work.

Signs you need orangery lantern repairs
- Leaks at the lantern edge or around the internal pelmet

Why it happens
Internal gutters
Box gutters around the lantern block and overflow inward.
Large-span movement
Bigger lanterns move more, stressing seals.

Guide prices for orangery lantern repairs in New Malden
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.
