We carry out upstand and kerb repairs in Greenwich and across the SE10 area. The upstand, or kerb, is the raised frame the lantern sits on.

Is it time for upstand and kerb repairs?

  • Soft or spongy timber at the base of the lantern
  • Roof membrane not lapped up the kerb, or peeling off it
  • Cold, damp or mouldy lining around the opening

What usually causes it?

Kerb too low

If the kerb doesn't rise enough above the finished roof, water sits against the joint during heavy rain.

Rotten timber

Untreated or wet timber kerbs rot from inside, so the lantern loses support and the seals open.

Covering Greenwich and nearby

Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.

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 Greenwich is roughly 6 miles — all part of the Greater London area we cover.

Close by, we also cover Blackheath (1 mile), Canary Wharf (2 miles), Catford (2 miles).

How much should it cost?

Guide price, per lantern£395–£1,295 ex VAT£474–£1,554 inc VAT

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?

In England, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010, so we set out the route in writing first. 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 Greenwich: questions

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 repair a lantern someone else installed in Greenwich?

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.

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.
