Red & Green Algae Render Removal & Professional Softwashing
If you have noticed unsightly pink, red, or green streaks creeping across your building’s exterior walls, you are dealing with a microscopic organism known as Trentepohlia (red algae) or standard green algae. These organisms thrive in damp, shaded British weather conditions. At Blue Whale SWS, our specialized red algae render removal protocols safely eradicate these infestations, restoring your building to its original condition.

The Problem with Algae on Modern Render
Modern monocouche and thin-render systems provide a food source for airborne spores. Once established, red and green algae penetrate the porous structure of the render. Simply blasting it with water will only wash away the surface layer—the spores remain embedded, and the stains will return within weeks. You need a dedicated green algae on render cleaner approach that treats the root cause.
How Our Professional Softwashing Works
- Spore Neutralization: Our professional soft wash formulas target and kill the algae spores entirely, rather than just bleaching them temporarily.
- Zero Surface Degradation: Because we rely on chemical chemistry rather than brute force, your delicate render texture remains completely intact.
- Extended Prevention: Treated walls stay cleaner for up to 4–5 times longer than pressure-washed surfaces because active biocide residue prevents new growth.
