In Westminster, as everywhere, when a lantern is letting in a lot of water or the glass is broken, the first job is to stop more damage. Send photos and we'll tell you what we think has failed.

Covering Westminster 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.
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.
Close by, we also cover Pimlico (1 mile), Chelsea (2 miles), Battersea (2 miles).
What should you expect to pay in Westminster?
Guide price for urgent leak make-safe: £195–£395 ex VAT (£234–£474 inc VAT), per visit. 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.
