Red Algae Cleaning FAQs
What is red algae?
Red algae is common in Ireland’s wet climate—especially on north-facing or poorly ventilated surfaces.
Is pressure washing enough?
Powerwashing often makes it worse. It doesn’t kill spores and can damage your surface.
Will it come back?
Our biocide kills spores and slows regrowth for up to 36 months, depending on surface and conditions.
Will your chemicals harm my garden?
Yes—our products are eco-friendly and water-based. We always rinse surrounding areas to protect your home, garden, and furry friends.
