Spray Mould & Moss Treatment Service

What’s Included in Our Spray Mould & Moss Treatment

Moss, mould, and algae not only make your court or surface look unappealing, but they also create safety hazards like slipperiness and water retention. Our targeted spray treatment is designed to safely remove and prevent organic growth on synthetic courts, hard surfaces, and other outdoor areas. Using commercial-grade, eco-friendly solutions, we break down growth at the source and help keep your surfaces safe and clean for longer.

Why Moss and Mould Removal Matters

Moss, mould, and algae thrive in shaded or damp areas, especially on tennis courts, walkways, driveways, and other outdoor surfaces. If left untreated, they can make the area dangerously slippery, stain the surface, and even accelerate wear or drainage issues.

Regular treatment prevents accidents, maintains the surface’s original look, and protects your investment from long-term damage. Our spray method penetrates deep into the surface, killing spores at the root — ensuring safer play and better appearance with minimal downtime.

Our 5-Step Moss & Mould Removal Process

We follow a proven method to ensure safe and thorough moss and mould elimination from all affected surfaces:

Site Evaluation & Surface Check

We assess the affected areas and determine the type and spread of growth.

Dry Debris Removal

Loose moss, leaves, and debris are cleared to allow effective treatment penetration.

Eco-Friendly Biocide Application

We apply a safe yet powerful moss/mould spray designed to kill spores without damaging your surface.

Dwell Time & Optional Rinse

The solution is left to activate and, if necessary, followed by a gentle rinse.

Post-Treatment Monitoring

We check results and provide reapplication suggestions if growth is likely to return.
