In Sunderland, 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
- Water appearing below the lantern rather than from the glass
- Soft or spongy timber at the base of the lantern
- Roof membrane not lapped up the kerb, or peeling off it
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.
Covering Sunderland and nearby
Snow and ice sitting at the eaves can block a lantern's drainage and push water back under the glass as it melts. If your lantern leaks after a thaw rather than after rain, tell us — it points to the eaves and kerb.
Urban grime and traffic film dull glass and frames quickly; a clean and seal check makes a tired lantern look and perform much better.
From Newcastle upon Tyne to Sunderland is roughly 10 miles — all part of the Tyne and Wear area we cover.

Guide prices for upstand and kerb repairs in Sunderland
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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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 Sunderland: questions
How do I get a price for upstand and kerb repairs in Sunderland?
Send a few photos of the lantern and the problem, with your Sunderland postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.
Can you repair a lantern someone else installed in Sunderland?
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.
