In Gainsborough, 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.

What you might be seeing
- 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.
Roof lanterns in Gainsborough
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
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.

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?
In England, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010, so we set out the route in writing first. 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.
