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 St Austell (PL25) 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
- Rotten or flaking timber on the lantern
- Misted units on a large lantern
Why it happens
Large-span movement
Bigger lanterns move more, stressing seals.
Timber maintenance
Painted timber orangeries need regular redecoration.
Roof lanterns in St Austell
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
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 Truro to St Austell is roughly 13 miles — all part of the Cornwall area we cover.
We also cover nearby Bodmin (9 miles), Truro (13 miles), Newquay (14 miles).
How much should it cost?
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.
