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 Harrow (HA2) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- Staining on the orangery ceiling
- Rotten or flaking timber on the lantern
- Misted units on a large lantern
Why it happens
Internal gutters
Box gutters around the lantern block and overflow inward.
Timber maintenance
Painted timber orangeries need regular redecoration.
Covering Harrow and nearby
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.
Across London, many lanterns sit on rear extensions with access only through the house, so we protect floors and plan the work to keep time indoors to a minimum. Parking and any permits are factored into the quote.
Harrow is around 10 miles from Westminster, and both are within our Greater London coverage.
We also cover nearby Wembley (2 miles), Northolt (3 miles), Greenford (4 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.
