Concrete Cleaning for Every Surface Across Your Brisbane Property

Every concrete cleaning job includes a surface assessment to identify the specific contamination type and surface condition. We pre-treat with sodium hypochlorite for mould and algae, alkaline degreasers for oil and grease, and oxalic acid-based treatments for rust staining. The clean is performed with commercial surface cleaners on flat areas for even, streak-free results, and hand lances with appropriate nozzles for vertical surfaces like retaining walls. We manage all runoff in accordance with local stormwater regulations. Damaged expansion joints, cracked render, or deteriorating mortar are flagged during our inspection so you can address them separately.

We clean all concrete surface types except driveways — that is a separate dedicated service. Our concrete cleaning covers garage floors and internal slabs, side and rear paths, house perimeter aprons, retaining walls in block, rendered block, and poured concrete, bin storage pads, clothesline pads, shed slabs, garden edging, stormwater pit surrounds, and commercial hardstand areas. Surface finishes we work with include plain grey concrete, coloured concrete, exposed aggregate, stamped concrete, stencilled concrete, and rendered surfaces in both acrylic and cement render.

We assess the surface type and contamination before selecting our approach. Flat horizontal surfaces like garage floors and slabs are pre-treated with the appropriate chemical, then cleaned with a surface cleaner for consistent results. Vertical surfaces like retaining walls are pre-treated and cleaned with a hand lance using a 25-degree or 40-degree fan tip, working from the bottom up to prevent streak marks. For oil-stained garage floors, we apply commercial degreaser, agitate with a stiff broom, allow dwell time, then clean with a turbo nozzle for maximum stain removal. All surfaces are rinsed clean and inspected before we finish.

Concrete surfaces across Brisbane properties are under constant attack from the subtropical climate. Garage floors accumulate oil and tyre residue that becomes permanent if left untreated. Side paths and house aprons sit in shade for most of the day, creating perfect conditions for mould and algae to establish thick, slippery layers. Retaining walls catch moisture runoff and organic debris, leading to algae growth that accelerates render deterioration. Brisbane’s storm season deposits silt and organic matter across every horizontal surface. Regular concrete cleaning prevents permanent staining, reduces slip hazards, and extends the life of coatings and sealers.
