Render Cleaning & Softwashing in Kent
Low-pressure softwash render cleaning — safe for painted render and K-rend, lifting green and black growth without a damaging blast.
Green algae and black spotting creep across rendered walls almost anywhere in Kent — and the wrong reaction, a high-pressure blast, is exactly what modern render can’t take. It can blow the finish off K-rend, strip paint and drive water into the wall. Pro O’s cleans render the safe way, with low-pressure softwashing: gentle enough for painted render, K-rend and silicone finishes, but effective at lifting the growth and grime sitting on the surface.
Because a wash alone leaves the spores behind, we finish with a biocide treatment that keeps the walls clear for years rather than a season — no repaint needed. Render finishes and their condition vary too much for a fair online price, so this one needs a site visit: we identify the finish, check how it’s holding up, and give you a firm, no-obligation quote.

Ask for a quote

Softwash clean
We apply a low-pressure softwash suited to the finish — no high-pressure blasting that can blow the render or drive water in.

Biocide treatment
A biocide kills remaining spores so the green and black growth stays away for far longer than cleaning alone.
Frequently asked questions
Is softwashing safe for my K-rend?
Yes — that's exactly why we use it. K-rend, silicone and painted renders can't take high pressure, so we clean at low pressure and let the treatment do the work.
Will it strip the colour or paint off the render?
No. Softwashing is gentle by design — it lifts the growth and grime sitting on the surface without stripping the finish underneath.
Why can't I get an instant online price?
Render finishes and their condition vary a lot, and the wrong method can cause damage. We visit first, then quote firmly with no obligation.
How long before the green comes back?
With the biocide treatment the surface stays clear far longer than a plain wash — typically years rather than a season.
