How much does pressure washing cost in Adelaide?
Pressure cleaning in Adelaide is charged at $37–$92 an hour, or as a set price per job: a standard driveway is $140–$370, typically $230, and a full exterior wash on a single-level home is $230–$645. A double-storey exterior costs $415–$1,000. Three in four Adelaide dwellings are separate houses (75%) and only 8.2% are flats (ABS 2021 Census), so most homes come with their own driveway, paths and outdoor paving to keep clean. What you pay depends on the surface, how dirty it is and whether it needs a chemical treatment as well as water.

What Affects Pressure Washing Costs in Adelaide
Driveways and paths
Concrete is the bread-and-butter job. A standard driveway costs $140–$370 and a concrete path or footpath $92–$200. Our table prices these per job rather than per square metre, so give the operator the size when you ask for a quote, or send photos. Oil drips and tyre marks need a degreaser first, which can push the job toward the top of the band.
One storey or two
A single-storey house wash is $230–$645; a second storey lifts it to $415–$1,000, because the upper walls need extension wands, ladders and more setting up. Semi-detached homes make up 16.3% of Adelaide dwellings, compared with 12.6% nationally (ABS 2021 Census), and a townhouse that shares walls has less exterior to wash.
Mould after the wet months
Adelaide's rain falls mainly in the cool half of the year: May to August each average more than 60 mm, and June tops the year at 72.1 mm (BOM averages), and July days average just 15.0 °C. Shaded paving and south-facing walls stay damp and grow mould and algae. A whole-house mould kill followed by a wash is $275–$830; a coat of inhibitor that holds back regrowth is an extra $46–$140.
Soft washing render and roofs
Render, painted weatherboards and roof tiles are usually cleaned at low pressure with a cleaning solution, because a high-pressure jet can strip paint and chip tiles. A soft wash of a single-storey house, walls and eaves, is $275–$600. Roof cleaning on a standard home runs $275–$1,200; leave it to an operator with roof access equipment.
Decks, patios and pool paving
A deck or patio clean is $140–$415 and pool surrounds or paving $140–$350. On timber the operator should drop the pressure and use a broad spray tip, otherwise the jet raises the grain and leaves boards furry. With January and February averaging only about 20 mm of rain (BOM averages), late summer is the easiest time to clean and re-oil a deck in one dry spell.
Fences and masonry walls
Fence washing is charged per lineal metre: $5–$17 to clean one face of a fence no taller than 1.8 m, which comes to about $270 for a 30 m back fence at a typical rate. One masonry or rendered wall, to roughly 30 m², costs $110–$275.
Handing back the keys
Renters make up 28.4% of Adelaide households (ABS 2021 Census). In South Australia a departing tenant is told to clean and tidy the property, gardens included, and to check its condition against the original inspection sheet. If that sheet records clean paving, a driveway or patio wash before the final inspection is a modest cost beside a dispute over the bond.
How to Save Money on Pressure Washing Cost in Adelaide
Pressure Washing Cost in Adelaide by Job Size
Say the job is a mixed list of small tasks and the operator expects it to take three hours. At $37–$92 an hour that is $111–$276. Priced as fixed rows instead, a driveway at $140–$370 plus a path at $92–$200 comes to $232–$570.
In Adelaide, give the operator the size or send photos, because the rows are per job. Oil drips and tyre marks can push a driveway toward the top of its band, a second storey moves the house wash from $230–$645 to $415–$1,000, and a semi-detached home with shared walls has less exterior to wash.
Pressure Washing Cost in Adelaide: What the Quote Should Include
Adelaide driveways and paths are priced as a job, not by the square metre, so a quote is only as good as the size written on it. Ask for the measurements or photos to be recorded, with oil marks, mould and the second storey each shown as separate lines.
- Driveway and path sizes recorded on the quote, or photos attached to it, because those rows are priced per job and not per square metre.
- Oil drips and tyre marks shown as a degreasing step ahead of the wash, on the driveway line at $140–$370.
- The house wash by storey, $230–$645 for one level and $415–$1,000 for two, with the ladders, wands and set-up for upper walls named.
- For a townhouse that shares walls, the walls in the wash listed, since shared walls leave less exterior to clean.
- Mould treatment for shaded paving and south-facing walls as a line at $275–$830, with an optional inhibitor at $46–$140.
- Render, painted weatherboards and roof tiles marked for a low-pressure soft wash, with the walls and eaves line at $275–$600.
- A timber deck at $140–$415 with the pressure and spray tip stated, so the grain is not raised.
- Fence runs in lineal metres, one face, against $5–$17 a metre, and any masonry or rendered wall counted at $110–$275.
- For a rental handover, a finish date ahead of the final inspection and a note of which paving the entry condition sheet records as clean.
