We carry out orangery lantern repairs in Dartford and across the DA1 area. 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.
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
Why it happens
Internal gutters
Box gutters around the lantern block and overflow inward.
Large-span movement
Bigger lanterns move more, stressing seals.
About Dartford and the DA1 area
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.
From Maidstone to Dartford is roughly 18 miles — all part of the Kent area we cover.
We also cover nearby Bexley (3 miles), Swanley (4 miles), Welling (5 miles).
How much should it cost?
Guide price for orangery lantern repairs: £395–£2,495 ex VAT (£474–£2,994 inc 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.
