Signs you need leak investigation and inspection

  • Previous repairs haven't stopped the leak
  • You're not sure if it's a leak or condensation
  • You need a written report for a landlord, insurer or builder

What usually causes it?

More than one fault

Older lanterns often have two or three small failures.

Not the lantern

Sometimes the source is the flat roof, a parapet, a gutter or a wall above.

Covering Holloway 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.

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.

From Westminster to Holloway is roughly 4 miles — all part of the Greater London area we cover.

Neighbouring places we cover include Highbury (1 mile), Archway (1 mile), Camden Town (1 mile).

Guide prices for leak investigation and inspection in Holloway

Guide price, per visit£145–£295 ex VAT£174–£354 inc VAT

Most leak investigation and inspection jobs come in between £145 and £295 ex VAT (£174–£354 including 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?

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.
