Chimney Rendering in Cornwall
Rendering, repointing and weatherproofing chimney stacks — the most exposed masonry on any house.
Our chimney rendering work in Cornwall starts with a free survey, because guessing at a render specification is how jobs go wrong.
Most of what we see around Cornwall reflects the wider Cornwall pattern — granite and cob cottages, slate-hung walls and exposed coastal housing, and driving-rain penetration and salt damage on exposed elevations. Cornwall sits in a part of the UK that gets severe driving rain and salt-laden coastal exposure — worth factoring into any render decision.
Local factor. Exposure here is category-defining — dashed and roughcast finishes genuinely outperform smooth render on west-facing coastal walls.
Is chimney rendering right for a Cornwall property?
Choose chimney rendering where a stack is spalling, the pointing has failed, or damp is showing in upstairs rooms near a chimney breast.
That decision gets made at the survey, not on the phone. We will tell you plainly if a different system would serve the building better — including when a cheaper one would.

FAQs
Chimney Rendering in Cornwall — questions
What time of year is best for rendering?
Spring through autumn is ideal. Render should not be applied in frost or in very hot direct sun, so winter work needs protection and settled conditions.
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.
