Aggregate Cleaning Perth

Aggregate is more porous and uneven than smooth concrete, which means it traps dirt, mould and organic growth more easily. Its rough surface can also become slippery when wet, especially if algae or moss are present. A professional clean lifts the contaminants without damaging the aggregate, helping the surface look great and stay safe.

It is safe when performed by a trained technician using the correct pressure and technique. Too much pressure or the wrong nozzle can loosen the aggregate stones or damage the cement base. We use carefully calibrated pressure and rotary surface cleaners to safely deep-clean without affecting the structural integrity of the surface.

Our cleaning process can remove a wide range of stains, including:

• Dirt and grime
• Mould and algae
• Rust marks
• Oil and grease
• Leaf tannins
• Tyre marks

Some deeply set stains may require spot treatments or chemical pre-sprays for best results.

Yes. The textured nature of aggregate means contaminants get embedded between the stones. We use surface cleaners and high-velocity rinsing to flush debris out of those gaps, ensuring a complete clean — not just on the surface, but deep into the texture.

Absolutely. Because aggregate is more porous than standard concrete, it’s highly susceptible to staining, moisture absorption and weathering. Sealing helps prevent future mould growth, enhances colour and appearance, and protects the surface from the elements. We recommend resealing every 2–3 years for best results.

For residential properties, once every 12–18 months is usually sufficient. If the area is prone to heavy foot traffic, shade, leaf litter or vehicle use, you may benefit from more regular cleaning to prevent stains and keep the surface looking fresh.
