Common Questions About Red Algae Cleaning
What is red algae?
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?
Our biocide kills spores and slows regrowth for up to 36 months, depending on surface and conditions.
Will your chemicals harm my garden?
We work clean, safe, and respectfully around your space.
