Stained render makes a smart home look abandoned
Render cleaning fixes London facades covered in red, green and black algae streaks. High-pressure washing gouges render — soft wash kills growth at the root so results last longer.
Algae streaks down walls
Vertical stains from roof to ground shout poor maintenance to every passer-by.
Wrong pressure scars render
DIY washers leave permanent marks on K-Rend and painted finishes.
Moisture trapped
Organic growth holds water against walls — paint and render fail sooner.
Sale value hit
Buyers discount heavily for stained front elevations — easy fix, big return.
Soft wash render cleaning — kills algae, protects walls
We apply low-pressure soft wash and biocide suited to your render type. Growth dies back and washes away without the blast marks cheap cleaners leave.
- Render type identified first
- Soft wash plus biocide treatment
- Windows and paths protected
- Even finish on large elevations
- Results that last longer than blasting

DIY, ignore it, or do it properly?
Pressure washing render is a one-way mistake. Leaving algae means repainting sooner.

Questions before you book
Is soft wash better than pressure washing render?
Yes on most modern renders. Biocide kills spores — blast pressure alone often damages the surface.
How long until I see full results?
Some improvement is immediate. Biocide continues working — full brightening can take a few weeks.
Do you clean pebbledash too?
Yes with adjusted methods. Tell us your wall finish when you quote.
Can render cleaning remove red and green algae streaks?
Yes. Soft wash and biocide kill algae on K-Rend, monocouche and painted render without cracking the surface.
Why should I avoid high pressure on rendered walls?
Strong jet pressure can chip and crack render. Our pressure washing team uses soft wash on walls where blast cleaning is not safe.
