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

Signs you need orangery lantern repairs
- Leaks at the lantern edge or around the internal pelmet
- Staining on the orangery ceiling
- Misted units on a large lantern
What usually causes it?
Internal gutters
Box gutters around the lantern block and overflow inward.
Large-span movement
Bigger lanterns move more, stressing seals.
Covering Swanley 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.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.

Guide prices for orangery lantern repairs in Swanley
Typical range: £395–£2,495 ex VAT, which is £474–£2,994 with 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.
