Algae
Green and red algae cause permanent staining on modern render and cladding. Discover our soft washing solutions for commercial and residential properties.
That persistent green or vivid red staining appearing on your exterior walls is not dirt; it is a complex, light-dependent biological colony. Algae spores are carried by the wind and thrive on modern, textured surfaces like K-Rend, silicone render, and composite cladding, turning bright, prestigious buildings into neglected-looking structures.
The Green and Red Facade Haze
That persistent green or vivid red staining appearing on your exterior walls is not dirt; it is a complex, light-dependent biological colony. Algae spores are carried by the wind and thrive on modern, textured surfaces like K-Rend, silicone render, and composite cladding, turning bright, prestigious buildings into neglected-looking structures.
The Science of UV Defense
Certain strains of algae, particularly the red/orange Trentepohlia, secrete a dense, waxy lipid layer (haematochrome) to protect themselves from severe UV radiation. This creates a highly hydrophobic (water-repelling) shield. This shield not only protects the organism but effectively traps harmful atmospheric moisture directly against the structural envelope of your building.
Why Traditional Cleaning Fails
Attempting to remove algae with standard pressure washing or generic bleach is highly ineffective. High pressure simply drives the spores deeper into the porous render, while off-the-shelf bleach merely lightens the color without destroying the biological anchor. This guarantees the algae will return thicker and darker within a single season.
The Soft Washing Solution
We deploy precise Soft Washing protocols to combat photosynthetic biofilms. Utilizing specifically calibrated, low-pressure application systems, we apply biocidal treatments that safely penetrate the algae's protective lipid shield. This scientifically lyses (breaks down) the cell walls, completely eradicating the colony while preserving the delicate finish of your modern render.
Transforming Envelopes and Cladding
Our soft washing methodology is the gold standard for vertical envelope cleaning. It is the core process utilized in our Residential Render Cleaning, Commercial Cladding Cleaning, and Brickwork Cleaning services across Buckinghamshire and Bedfordshire, restoring the original aesthetic value of your property without the risk of high-pressure damage.
Protecting Your Property's Value
