In Willesden, as everywhere, the upstand, or kerb, is the raised frame the lantern sits on. Send photos and we'll tell you what we think has failed.

What you might be seeing
- Soft or spongy timber at the base of the lantern
- Ponding water against the kerb after rain
- Cold, damp or mouldy lining around the opening
Common causes we find
Membrane not dressed up
The flat roof covering should run up the kerb and be trimmed or flashed. If it stops short, water gets behind it.
Rotten timber
Untreated or wet timber kerbs rot from inside, so the lantern loses support and the seals open.
About Willesden and the NW10 area
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.
Willesden is around 5 miles from Westminster, and both are within our Greater London coverage.

Guide prices for upstand and kerb repairs in Willesden
Guide price for upstand and kerb repairs: £395–£1,295 ex VAT (£474–£1,554 inc VAT), per lantern. 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.

Upstand and kerb repairs in Willesden: questions
How do I get a price for upstand and kerb repairs in Willesden?
Send a few photos of the lantern and the problem, with your Willesden postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.
Do you need to visit to price upstand and kerb repairs?
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 add insulation to the kerb?
Yes. Insulated kerbs reduce cold bridging and help with condensation around the opening.
Will my ceiling need repairing?
If water has soaked the lining it may need making good after the leak is fixed; we can advise, but internal decorating isn't included unless quoted.
