We carry out upstand and kerb repairs in Hitchin and across the SG4 area. The upstand, or kerb, is the raised frame the lantern sits on.

Signs you need upstand and kerb repairs

  • 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

Why it happens

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 Hitchin and nearby

Most inland lantern leaks aren't storm damage; they're usually tired sealant, a lifted capping or blocked eaves drainage. All three are quick to find and fix once you know where to look.

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?

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 Hitchin: 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 Hitchin?

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.

How much does an upstand repair cost?

Typically £395–£1,295 ex VAT depending on size, timber condition and the roof covering. The fixed price is confirmed in writing before work starts.

Can you add insulation to the kerb?

Yes. Insulated kerbs reduce cold bridging and help with condensation around the opening.
