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.
Can’t I just powerwash it?
Powerwashing often makes it worse. It doesn’t kill spores and can damage your surface.
How long does your treatment last?
Most clients see zero return for 2–3 years. It’s a long-term win.
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.
