We carry out upstand and kerb repairs in Porthcawl and across the CF36 area. The upstand, or kerb, is the raised frame the lantern sits on.

Signs you need upstand and kerb repairs

  • Water appearing below the lantern rather than from the glass
  • Roof membrane not lapped up the kerb, or peeling off it
  • Ponding water against the kerb after rain

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.

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.

About Porthcawl and the CF36 area

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.

Porthcawl is around 6 miles from Bridgend, and both are within our Mid Glamorgan coverage.

If you're just outside Porthcawl, we also cover Bridgend (6 miles), Port Talbot (8 miles), Maesteg (9 miles).

How much should it cost?

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

Most upstand and kerb repairs jobs come in between £395 and £1,295 ex VAT (£474–£1,554 including 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?

In Wales, 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 (as applied in Wales), so we set out the route in writing first. 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 Porthcawl: questions

How do I get a price for upstand and kerb repairs in Porthcawl?

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

Which places near Porthcawl do you cover?

As well as Porthcawl, we cover nearby Bridgend, Port Talbot, Maesteg, Llantwit Major and the rest of Mid Glamorgan.

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.
