What usually causes it?

Hidden water paths

Water can travel along bars, decks and linings before it shows.

More than one fault

Older lanterns often have two or three small failures.

Covering Archway and nearby

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.

From Westminster to Archway is roughly 5 miles — all part of the Greater London area we cover.

We also cover nearby Holloway (1 mile), Muswell Hill (2 miles), Chalk Farm (2 miles).

How much should it cost?

Guide price for leak investigation and inspection: £145–£295 ex VAT (£174–£354 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.
