Damp-Proof Render in Cornwall
Specialist waterproof and salt-resistant render systems for damp-affected and below-ground walls.
If you are weighing up damp-proof render in Cornwall, the starting point is what your walls are actually built from.
Cornwall is characterised by granite and cob cottages, slate-hung walls and exposed coastal housing, with driving-rain penetration and salt damage on exposed elevations the recurring theme on the properties we survey. With severe driving rain and salt-laden coastal exposure, specification matters more in this part of the country than a national price list suggests.
Local factor. Exposure here is category-defining — dashed and roughcast finishes genuinely outperform smooth render on west-facing coastal walls.
Is damp-proof render right for a Cornwall property?
Choose a damp-proof system after flooding, alongside DPC works, on below-ground walls, and wherever salt contamination is destroying normal plaster.
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
Damp-Proof Render in Cornwall — questions
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.
Does damp-proof render cure rising damp?
No — it manages the consequences. The damp-proof course or the source of water has to be dealt with separately. The render then holds back residual moisture and salts while the wall dries.
Is waterproof render the same as tanking?
Related but not the same. Tanking is a higher-specification below-ground system designed to resist water under pressure; waterproof render is for above-ground damp resistance.
How much does rendering cost?
It is priced by the square metre and depends on the system, the condition of the walls and access. Our guide-price tool gives an indicative range in about a minute, and the survey turns that into a fixed written quote.
Do you offer a guarantee?
Yes. Every job carries our workmanship guarantee, and where a full manufacturer-specified system is installed you also get the system warranty on top.
