Professional Soft Wash Render Cleaning in Bristol
Bristol's wet climate turns rendered exteriors green within a few years of application. Algae and lichen embed into the render surface, causing staining that looks permanent — but isn't. Our soft wash system uses biodegradable cleaning solutions at low pressure to kill growth at the root and restore the original colour, safely and without damage.

Render Cleaning Bristol FAQ
Do you clean rendered properties across all Bristol postcodes?
Yes. We cover all Bristol postcodes from BS1 to BS16. Our soft wash system is used on K-Rend, silicone render, painted render and monocouche finishes across Clifton, Redland, Bishopston, Henleaze, Kingswood, Brislington and all surrounding areas.
Why use soft wash instead of jet washing for render in Bristol?
High-pressure jet washing can force water behind render, cause cracking and strip painted finishes. Our soft wash system uses low pressure and specialist biodegradable cleaning solutions to kill algae and bacteria at the root — without damaging the render surface. It's the only safe method for K-Rend, silicone and painted finishes.
Why does Bristol render go green so quickly?
Bristol's wet south-westerly climate, high humidity and relatively mild winters create near-perfect conditions for algae and lichen growth on exterior render. North and west-facing elevations are worst affected. Our biocide treatment kills the growth and significantly slows regrowth after cleaning.
How much does render cleaning cost in Bristol?
Render cleaning in Bristol starts from £89 for a standard terraced or semi-detached property, depending on the size of the elevation and extent of staining. We provide free, no-obligation quotes — call 07474 939 398.
Will soft wash cleaning affect my render warranty in Bristol?
No. Soft wash is the manufacturer-recommended cleaning method for K-Rend, Weber and other proprietary render systems. High-pressure washing can void render warranties — our soft wash system does not.
