The upstand, or kerb, is the raised frame the lantern sits on. Send photos from Llangefni (LL77) 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?
- Roof membrane not lapped up the kerb, or peeling off it
- Ponding water against the kerb after rain
- 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 Llangefni and nearby
Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.
From Bangor, Gwynedd to Llangefni is roughly 8 miles — all part of the Gwynedd area we cover.

What should you expect to pay in Llangefni?
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 Wales?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Wales. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010 (as applied in Wales); we confirm in writing which route applies before any replacement. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.

Upstand and kerb repairs in Llangefni: questions
How do I get a price for upstand and kerb repairs in Llangefni?
Send a few photos of the lantern and the problem, with your Llangefni 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.
