We carry out upstand and kerb repairs in Wrexham and across the LL13 area. The upstand, or kerb, is the raised frame the lantern sits on.

Is it time for upstand and kerb repairs?
- Water appearing below the lantern rather than from the glass
- Soft or spongy timber at the base of the lantern
- Ponding water against the kerb after rain
What usually causes it?
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 Wrexham and nearby
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
Neighbouring places we cover include Buckley (9 miles), Mold (10 miles), Deeside (11 miles).

Do you need permission in Wales?
Most lantern repairs in Wales need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 (as applied in Wales) apply and we confirm how the work will be signed off before we start. 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.

Send a few photos of the lantern and the problem, with your Wrexham postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.

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.

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.
