In Chalk Farm, 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
- 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.
About Chalk Farm and the NW3 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.
London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.
We cover Chalk Farm as part of Greater London, about 3 miles from Westminster.

What should you expect to pay in Chalk Farm?
Most orangery lantern repairs jobs come in between £395 and £2,495 ex VAT (£474–£2,994 including 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?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.
