Biocide Treatment
What is a Biocide and How Does it Work for Exterior Cleaning?
A biocide is a specialized chemical treatment designed to eliminate and inhibit the growth of unwanted organic matter like moss, algae, lichen, mould, and fungi on exterior surfaces. Unlike simply washing away visible growth, biocides work at a microscopic level.
When applied, the biocide penetrates the porous surfaces of your roof, patio, driveway, or render. It disrupts the cellular structure of these organisms, effectively killing them at the root. This not only cleans the surface but, crucially, prevents their immediate regrowth by sterilising the spores.
The key benefit of a biocide treatment is its lasting effect, providing long-term protection and keeping your surfaces cleaner for much longer than a pressure wash alone.6 It's an essential part of professional exterior cleaning for truly restored and protected properties in North Walsham, Norfolk, and Suffolk.
Application
For superior exterior cleaning, biocide is typically applied via a low-pressure spray system, or water fed pole brush head. This ensures even coverage and deep penetration into porous surfaces like roof tiles (e.g., concrete, clay, slate), patios, driveways, and render in North Walsham, Norfolk, and Suffolk. This method allows the biocide solution to effectively target and kill moss, algae, lichen, mould, and fungi at the root, preventing regrowth without damaging the surface. It's a key step for long-term protection and restoring your property's appearance.

How long dose it last?
Once applied by Wrights Dirt Blasters, the effectiveness of a biocide treatment on your exterior surfaces can vary, but generally provides long-lasting protection.
For surfaces like roofs, patios, and driveways in North Walsham, Norfolk, and Suffolk, a professional-grade biocide will typically work to inhibit moss, algae, and lichen regrowth for 12 to 24 months. In ideal conditions (less shade, good drainage), some advanced formulas can even offer protection for up to 3 years or more.
Factors like the specific biocide solution used, the porosity of the surface (e.g., concrete tiles vs. smoother slate), the level of initial organic growth, and environmental conditions (e.g., shade, humidity) can all influence how long the treatment remains effective. Regular maintenance cleaning with a biocide every 1-2 years is often recommended to ensure consistent long-term protection and keep your property looking its best.
