Chimney Specialists Serving Aberdare
Nearly every terrace in Aberdare still carries its original chimney stacks - and they have stood in the wind off the mountains for a century or more. No part of a valley roof takes more weather, and none is more often ignored until something falls.
Chimney problems travel downwards. Failed flaunching lets water into the stack; saturated masonry pushes damp into bedrooms; loose pots and copings become dangerous in the next gale. Caught early, a repoint fixes it - left alone, it becomes a rebuild.
We trace the actual fault before quoting – flaunching, flashing, mortar or masonry – and fix that, not everything we can think of. Honest chimney work from the Aberdare roofer your neighbours already use.

Frequently Asked Questions
Straight answers about chimney repairs in Aberdare.
Why is my chimney breast damp?
The usual suspects are failed lead flashing, cracked flaunching or masonry so weathered it soaks up rain. We trace the actual source first – repointing a stack when the flashing is the fault fixes nothing.
Repoint or rebuild - how do I know?
If the masonry is sound, repointing restores the stack for decades. If bricks are spalled and the stack moves or leans, a partial or full rebuild is the honest answer. We show you photos and price what is actually needed.
My chimney is unused - should I just remove it?
Not necessarily – capping with ventilation is usually cheaper and keeps the roofline intact. Removal makes sense when a stack is beyond economic repair; we will price both options straight.
How long does repointing last?
Done properly with the right mortar mix, 25-50 years depending on exposure – and stacks on the valley tops face serious exposure, so we spec accordingly.
Do you need scaffolding for chimney work?
Almost always – a tower or roof scaffold for safe access is included in the written quote, never a surprise extra.
Which areas do you cover?
