Cleaner for Longer.
Standard washing can remove visible growth, but spores often remain. Biocide soaks into the surface to kill what’s left, meaning patios, roofs, and render stay cleaner between visits.

Helps Prevent
Rapid Regrowth.
Without treatment, green algae and moss can start returning within months. Applying biocide creates a hostile environment for regrowth, so staining comes back much more slowly.

Frequently Asked Questions 🧠
What is a biocide treatment and how does it work?
A biocide treatment is a specialist solution applied to surfaces to kill moss, algae, lichen, and other organic growth. It soaks into the pores and breaks down what’s left after cleaning, including hidden spores.
Which surfaces can you treat with biocide?
Biocide can be used on most exterior surfaces, including roofs, render, patios, driveways, and some brick or stone, as long as they are suitable for wet application and are in sound condition.
Is biocide treatment safe for my family, pets, and plants?
When used correctly, biocides are applied at controlled strengths and allowed to dry. Pets and children should be kept off treated areas until fully dry, and nearby plants are rinsed or covered for protection.
How long does a biocide treatment last?
Results typically last 12–24 months depending on the surface and how shaded or damp the area is. You’ll usually see staining fade over several weeks, with slower regrowth compared to cleaning alone.
Do you need to pressure wash before applying biocide?
For best results, heavy growth and loose debris are removed first, either by soft washing or low‑pressure cleaning, then biocide is applied to deal with remaining spores and help keep the surface cleaner for longer.
