We carry out urgent leak make-safe in Cardiff and across the CF10 area. When a lantern is letting in a lot of water or the glass is broken, the first job is to stop more damage.

What you might be seeing
- Water pouring in during a storm
- A capping or vent blown off
- Water near light fittings or sockets
What usually causes it?
Storm damage
High winds can lift cappings and vents.
Sudden seal failure
A failing joint can let go in heavy rain.
Covering Cardiff 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.
If you're just outside Cardiff, we also cover Penarth (3 miles), Caerphilly (7 miles), Barry (7 miles).
Guide prices for urgent leak make-safe in Cardiff
Most urgent leak make-safe jobs come in between £195 and £395 ex VAT (£234–£474 including 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.
