How We Clean Red Algae Safely
This isn’t a spray-and-go operation. Our process is designed for long-term results.
- 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: The surface is gently rinsed, leaving behind zero mess and a streak-free finish.
The end result? A home that looks fresh and stays cleaner longer—without any damage.
