Biocide Treatment done with the surface in mind
Biocide treatment is used to target biological growth such as algae, moss and lichen on suitable exterior surfaces. Rather than relying only on physical force, a professional treatment works on the organic contamination itself and can be used as part of a wider roof, wall or hard-surface cleaning plan.
The right treatment depends on the surface, the type and extent of growth, nearby vegetation and how quickly the area needs to look clean. Some treated surfaces continue to improve gradually as weathering removes dead growth, while other jobs benefit from careful physical cleaning before treatment.
Why the right cleaning method matters
On coastal and shaded properties, organic growth can return quickly if the underlying conditions remain damp. Biocide can be valuable as a maintenance tool after cleaning because it addresses spores and growth left in textured or porous surfaces that are difficult to remove mechanically.
We do not apply chemicals indiscriminately. Products, strength, coverage and rinse requirements are chosen for the job, with attention paid to runoff, surrounding materials and the condition of the substrate.
What this service is suitable for
Every property is assessed individually, but biocide treatment is commonly requested for the following exterior surfaces and maintenance jobs:
How we approach biocide treatment
Identify
We assess the type of growth, surface and surrounding area.
Prepare
The working area and any sensitive surrounding features are considered before application.
Apply
Treatment is applied in a controlled, even way appropriate to the substrate.
Allow to work
Where a leave-on treatment is appropriate, we explain the expected weathering and improvement period.
