Chimney Rendering in Cardiff
Rendering, repointing and weatherproofing chimney stacks — the most exposed masonry on any house.
If you are weighing up chimney rendering in Cardiff, the starting point is what your walls are actually built from.
Across South Glamorgan, Victorian and Edwardian terraces, Cardiff suburban housing and coastal properties dominates, and solid-wall terrace damp and coastal weathering at Barry and Penarth is what we are called out to most often.
Cardiff sits in a part of the UK that gets wet with coastal exposure along the Severn estuary — worth factoring into any render decision. Cardiff's victorian terraces are largely solid-wall, and external insulation with a breathable render is the upgrade that suits them best.
When chimney rendering is the right call. Choose chimney rendering where a stack is spalling, the pointing has failed, or damp is showing in upstairs rooms near a chimney breast.

FAQs
Chimney Rendering in Cardiff
Can you render over existing render?
Sometimes, if the existing coat is completely sound and well-bonded. We hammer-test it first. Anything hollow has to come off, because covering failure just hides it.
Are you insured?
Yes — full public liability cover, and we can send the certificate before we start. We are happy to provide RAMS for commercial and contractor work.
What areas do you cover?
We work UK-wide, with teams across England, Scotland, Wales and Northern Ireland. If we are not the right firm for your location we will tell you rather than waste your time.
Why is my chimney causing damp?
Water enters through failed flaunching, cracked render, open pointing or defective flashings, then runs down inside the flue and shows as staining on a chimney breast, often on the floor below.
What is flaunching?
The mortar fillet that beds the chimney pots into the top of the stack and sheds water off it. It cracks and fails with age and is a very common leak point.
