Is it time for 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

Why it happens

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 Chelsea 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.

We cover Chelsea as part of Greater London, about 2 miles from Westminster.

Close by, we also cover Battersea (1 mile), Fulham (1 mile), Pimlico (1 mile).

How much should it cost?

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

Typical range: £145–£295 ex VAT, which is £174–£354 with 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.

Leak investigation and inspection in Chelsea: questions

Do you need to visit to price leak investigation and inspection?

Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.

Can you repair a lantern someone else installed in Chelsea?

Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.

Is the visit cost deducted from the repair?

Ask when you book — we'll confirm in writing how the visit is charged if you go ahead with the repair.

Do you provide a report?

Yes, with photos and findings, which is useful for landlords, insurers and disputes with installers.
