Our Red Algae Removal Process
We don’t blast it. We treat it—properly. Our softwash system is specially designed for delicate surfaces like painted walls, dash, render, and roof tiles. Here’s how we tackle red algae safely and effectively:
- Surface Inspection: We assess the extent of red algae coverage and surface type to select the safest approach.
- Softwash Application: A gentle solution is applied that breaks down algae without pressure or surface damage.
- Biocide Treatment: A targeted biocide is applied to destroy microscopic spores and prevent regrowth for 18–36 months.
- Final Rinse: We gently rinse the surface to leave it looking fresh, clean, and streak-free.
The result? A spotless finish and long-lasting protection—with no peeling paint, no pressure cracking, and no hassle.

Red Algae Cleaning FAQs
What is red algae and why does it appear?
Red algae is a type of bacteria that thrives in damp conditions, especially on shaded or north-facing walls. It leaves red or pink streaks on render, paint, and rooftops.
Can I just powerwash it off?
We don’t recommend it. Powerwashing can damage render or paint and won’t kill algae spores. We use softwash with biocide to clean safely and stop it coming back.
Will it come back after cleaning?
Our biocide treatment kills algae at the source and typically prevents regrowth for 18–36 months, depending on exposure and environment.
Is it safe for pets and plants?
Yes. We use eco-safe, water-based solutions and rinse down all surrounding areas to protect your garden, pets, and family.
