Render Cleaning in Cornwall
Soft-wash render cleaning and biocide treatment that removes algae without damaging the finish.
Render Cleaning in Cornwall is work we take on regularly, and the Cornwall housing stock is a big part of why.
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. The area sees severe driving rain and salt-laden coastal exposure, which is the single biggest factor in how long any render lasts here.
Local factor. Exposure here is category-defining — dashed and roughcast finishes genuinely outperform smooth render on west-facing coastal walls.
Is render cleaning right for a Cornwall property?
Choose soft-wash cleaning to restore a discoloured render without the substrate damage that pressure washing causes on thin-coat systems.
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
Render Cleaning in Cornwall — questions
Can I pressure wash my render?
We strongly advise against it on thin-coat silicone, acrylic and monocouche. High pressure erodes the finish and forces water behind it. Soft washing is the safe method.
Will cleaning restore the original colour?
On through-coloured render, usually yes — the colour is intact under the growth. On painted render, cleaning may reveal that the paint itself has faded unevenly.
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.
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.
