When a lantern is letting in a lot of water or the glass is broken, the first job is to stop more damage. Send photos from Caerphilly (CF83) and we'll tell you which it is — with the price agreed in writing before any work.

High winds can lift cappings and vents.
Sudden seal failure
A failing joint can let go in heavy rain.
Covering Caerphilly 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.
From Newport, Gwent to Caerphilly is roughly 9 miles — all part of the Gwent area we cover.
If you're just outside Caerphilly, we also cover Risca (6 miles), Pontypridd (6 miles), Blackwood (6 miles).
What should you expect to pay in Caerphilly?
Typical range: £195–£395 ex VAT, which is £234–£474 with VAT, per visit. 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.
