Not the lantern
Sometimes the source is the flat roof, a parapet, a gutter or a wall above.
Roof lanterns in Kilburn
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.
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.
Kilburn is around 5 miles from Westminster, and both are within our Greater London coverage.
If you're just outside Kilburn, we also cover Cricklewood (1 mile), Chalk Farm (2 miles), Camden Town (2 miles).
What should you expect to pay in Kilburn?
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.

Leak investigation and inspection in Kilburn: 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 Kilburn?
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.
