We carry out upstand and kerb repairs in Welshpool and across the SY21 area. The upstand, or kerb, is the raised frame the lantern sits on.

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
  • Ponding water against the kerb after rain

Common causes we find

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 Welshpool 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.

We cover Welshpool as part of Powys, about 12 miles from Newtown.

Close by, we also cover Newtown (12 miles), Wrexham (28 miles), Machynlleth (30 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.

Upstand and kerb repairs in Welshpool: questions

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

Send a few photos of the lantern and the problem, with your Welshpool 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 Welshpool do you cover?

As well as Welshpool, we cover nearby Newtown, Wrexham, Machynlleth, Llandrindod Wells and the rest of Powys.

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.
