Red Algae Cleaning FAQs
Why does red algae appear?
It’s a form of airborne bacteria that thrives on damp surfaces, especially shaded render, walls, and rooftops.
Is pressure washing enough?
Powerwashing often makes it worse. It doesn’t kill spores and can damage your surface.
How long does your treatment last?
Our biocide kills spores and slows regrowth for up to 36 months, depending on surface and conditions.
Is it safe for pets and plants?
Yes—our products are eco-friendly and water-based. We always rinse surrounding areas to protect your home, garden, and furry friends.
