High Pressure Water Cleaning Services Sydney

We clean concrete driveways, brick and block paving, sandstone, rendered walls, timber decks, composite decking, Colorbond fences, tiled pool surrounds, garage floors, retaining walls, and exterior cladding. Each surface needs a different pressure setting and tip. Concrete handles 3,000+ PSI while sandstone and timber typically need 1,200 to 1,800 PSI with a wider fan to avoid etching or grain damage. We assess the surface on site and match the equipment to the material.

Yes, when the pressure and technique are matched to the surface. Damage from pressure cleaning almost always comes from using too much pressure on a soft material or holding the nozzle too close. We use adjustable machines, multiple tip sizes, and vary the working distance depending on whether we are cleaning concrete, sandstone, timber, or render. We also protect garden beds, cover downlights or low fixtures, and redirect water away from areas that should stay dry.

Most residential jobs take between two and six hours depending on the total area, the number of different surfaces involved, and how heavy the staining is. A standard two-car driveway with moderate mould build-up typically takes two to three hours. A full property clean covering driveway, paths, patio, and fences is usually a single-day job. We confirm estimated duration in the quote so you know what to expect.

For most Sydney properties, every twelve to eighteen months keeps surfaces in good condition. Properties with heavy shade, south-facing walls, or proximity to bushland tend to build mould and algae faster and benefit from an annual clean. Coastal properties also accumulate salt residue that dulls surfaces more quickly. Driveways with regular vehicle use may need attention sooner if oil or tyre marks are a concern. We can recommend a schedule after seeing the property.

For most surfaces, water pressure alone does the job. For heavy mould, embedded algae, or oil stains we use targeted pre-treatments applied to the affected area before cleaning. We do not use broad-application chemical washes across the whole site. Runoff is managed on site and directed away from storm drains and garden beds in line with Sydney Water guidelines.

Oil stains and tyre marks on concrete respond well to pressure cleaning, especially when we pre-treat with a degreaser and let it dwell before cleaning. Fresh stains lift more completely than old, deeply absorbed ones. Long-standing oil stains may lighten significantly but can leave a shadow depending on how porous the concrete is and how long the oil has been sitting. We will be upfront about expected results during the quote so there are no surprises.
