Pressure Washing Cost Australia 2026
Pressure washing costs depend on the surface type and area, degree of soiling, whether chemical treatment is needed, and whether multiple surfaces are included.

Pressure washing in Australia costs $40–$100/hr, or from $150–$300 for a standard driveway clean. A full house exterior wash runs $150–$350. Decking and paving is $250–$700. Regular pressure washing extends the life of concrete, timber, and rendered surfaces and dramatically improves street appeal.
Pressure Washing Costs by Surface and Job Size
Pressure washing is priced by the surface and its area, not by the room. Here is what the common jobs cost across Australia:
| Job | Cost Range | Notes |
|---|---|---|
| Pressure washing (hourly rate) | $40–$100 /hr | Common for mixed or small jobs |
| Driveway cleaning (standard) | $150–$300 | Standard single or double driveway |
| Full house exterior wash | $250–$700 | Walls, eaves and hard surfaces |
| Deck / patio cleaning | $150–$350 | Timber or composite, lower pressure |
| Fence cleaning (per lm) | $5–$18 /lm | Priced per linear metre |
| Roof cleaning (standard home) | $300–$1,300 | Soft wash — high pressure damages tiles |
| Pool surrounds / paving | $100–$380 | Coping, paving and pool decking |
| Concrete path / footpath | $60–$220 | Paths and footpaths |
| Brick / rendered wall cleaning | $80–$300 | Render needs low pressure |
| Soft washing (low-pressure, per hour) | $50–$120 /hr | Chemical clean for delicate surfaces |
| Commercial building wash | $400–$2,000 | Strata and commercial facades |
| Mould treatment & wash (full exterior) | $300–$1,300 | Treats the growth, not just the surface |
Area drives the price more than anything else, so a quote given without someone seeing the job — or at least a photo and a rough square-metre figure — is a guess. Access matters too: a second-storey wall or a roof adds harness and ladder time. Water is usually drawn from your tap, so ask whether that is assumed and whether run-off needs containing, which some councils require near stormwater drains.
High-Pressure vs Soft Washing: Which Does Your Surface Need?
Using the wrong one is the most expensive mistake on this trade — high pressure on the wrong surface causes damage that costs far more than the clean:
| Factor | High pressure | Soft washing |
|---|---|---|
| Typical rate | $40–$100 | $50–$120 |
| How it works | Mechanical force strips the surface | Low-pressure chemical kills the growth |
| Best for | Concrete, driveways, paving, brick | Roofs, render, painted timber, Colorbond |
| Mould and lichen | Removes what is visible; regrows sooner | Kills at the root; stays clean longer |
| Damage risk | Can etch render, strip paint, lift roof tiles | Low |
| Safe on a roof? | No — not on tile or painted metal | Yes — this is the standard for roofs |
If a quote offers high pressure on your roof or rendered walls, treat it as a red flag rather than a bargain. Render, painted surfaces and roof tiles are all cleaned at low pressure with a treatment that kills the growth; the visible result is slower to appear but lasts considerably longer. Concrete, paving and brick are the surfaces where genuine high pressure belongs.
What Affects Pressure Washing Costs in Australia
Surface type
Concrete driveways and paths in Australia ($150–$300) are the most common. Decking, paving, rendered walls, and brick all have different pressures and methods needed to avoid damage.
Area size
Larger areas get a better rate per sqm in Australia. A small courtyard is proportionally more expensive per sqm than a large driveway or commercial car park.
Degree of soiling
Light mould and algae on a recently built surface clean quickly. Years of embedded grime, tyre marks, and extensive biological growth in Australia take much longer and may require chemical pre-treatment.
Chemical treatment
Some surfaces benefit from hot water or chemical pre-treatment for mould, algae, or rust stains. This adds cost but produces better results for heavily soiled Australia properties.
Access & obstacles
Cars need moving, furniture relocating, and drains protecting. Tight spaces and upstairs balconies in Australia take longer to set up and access safely.
Roof cleaning
Roof pressure washing in Australia ($300–$1,300) requires specialist equipment and training — incorrect pressure on terracotta or concrete tiles causes damage. Always use a specialist for roofs.
