We carry out aluminium roof lantern repairs in Caerphilly and across the CF83 area. Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear.
What you might be seeing
- Leaks at bars or ridge
- Cappings lifted or rattling
- Misted units
What usually causes it?
Thermal movement
Aluminium moves with temperature; seals and fixings take the strain.
Finish damage
Scratches and chips expose bare metal; coastal air speeds up corrosion.
About Caerphilly and the CF83 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.
Caerphilly is around 9 miles from Newport, Gwent, and both are within our Gwent coverage.
Close by, we also cover Risca (6 miles), Pontypridd (6 miles), Blackwood (6 miles).
What should you expect to pay in Caerphilly?
Typical range: £195–£695 ex VAT, which is £234–£834 with 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?
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.
