- Inspection: We check the surface type, algae severity, and exposure before we begin.
- Softwash Application: We apply a gentle detergent to dissolve algae without harming paint, render, or tiles.
- Biocide Treatment: Once cleaned, we apply a biocide to eliminate spores and prevent regrowth for up to 36 months.
- Rinse Down: Final rinse leaves your property looking crisp, clean, and algae-free.
Quick. Safe. Lasting. That’s how red algae should be handled.
