The upstand, or kerb, is the raised frame the lantern sits on. Send photos from Greenford (UB6) and we'll tell you which it is — with the price agreed in writing before any work.
Is it time for upstand and kerb repairs?
- Water appearing below the lantern rather than from the glass
- Ponding water against the kerb after rain
- Cold, damp or mouldy lining around the opening
Why it happens
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 Greenford and the UB6 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.
From Westminster to Greenford is roughly 10 miles — all part of the Greater London area we cover.
Close by, we also cover Northolt (1 mile), Southall (2 miles), Wembley (3 miles).
How much should it cost?
Typical range: £395–£1,295 ex VAT, which is £474–£1,554 with 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.
