About Merthyr Tydfil and the CF47 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.
From Bridgend to Merthyr Tydfil is roughly 19 miles — all part of the Mid Glamorgan area we cover.
If you're just outside Merthyr Tydfil, we also cover Aberdare (4 miles), Tredegar (6 miles), Rhondda (7 miles).
How much should it cost?
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.
