Render Cleaning in Penzance
Soft-wash render cleaning and biocide treatment that removes algae without damaging the finish.
Getting render cleaning right in Penzance depends far more on the substrate and the exposure than on the product name.
Across Cornwall, granite and cob cottages, slate-hung walls and exposed coastal housing dominates, and driving-rain penetration and salt damage on exposed elevations is what we are called out to most often.
Local conditions bring severe driving rain and salt-laden coastal exposure, and that has a direct bearing on which systems are worth specifying. Exposure here is category-defining — dashed and roughcast finishes genuinely outperform smooth render on west-facing coastal walls.
When render cleaning is the right call. Choose soft-wash cleaning to restore a discoloured render without the substrate damage that pressure washing causes on thin-coat systems.

FAQs
Render Cleaning in Penzance
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.
