How much does pressure washing cost in Wollongong?
Pressure washing in Wollongong is charged either by the hour, at $43–$110, or as a fixed price for each job.

What Affects Pressure Washing Costs in Wollongong
Water rules for hard surfaces
The Illawarra is covered by the Water Wise Guidelines, the everyday water-use rules set by its water utility. Cleaning paths, driveways, concrete or paving with drinking water is not allowed unless it is needed for safety, health or emergency reasons, construction activity or surface contamination, and run-off or overspray onto pathways is not permitted either. The guidelines don't apply to recycled or tank water, so ask how the operator works within them before you book.
Wet summers and mould
February and March are the wettest months at the university weather station, averaging 156.4 mm and 160.4 mm (BOM averages), and summer days stay mild at about 25 °C. Shaded paving, damp walls and timber decks grow mould and algae in that weather. A mould treatment with a full exterior wash costs $325–$970, and an inhibitor to slow regrowth adds $54–$160.
Soft wash for render and paint
High pressure can strip paint and etch render, so many operators switch to a low-pressure soft wash with a cleaning solution for walls. On a single-storey house, walls and eaves, it costs $325–$700. The typical soft wash at $520 sits a little above the $455 typical for a standard exterior wash.
Second storeys and roofs
Upper walls need ladders, extension wands or access gear, which takes a two-storey exterior wash up to $485–$1,200. Roof cleaning is specialist work at $325–$1,400: too much pressure can crack terracotta and wear the surface coating off concrete tiles, so ask how the operator cleans the roof without heavy foot traffic on the tiles.
Paths, paving and pool surrounds
Three-bedroom homes are the most common size in Wollongong, 41.6% of dwellings against 34.7% across NSW (ABS 2021 Census), and their outdoor areas are priced piece by piece. Paths and footpaths cost $110–$240, pool surrounds and paving $160–$410, and a single brick, block or rendered wall of up to roughly 30 square metres $130–$325.
Fences, unit blocks and shopfronts
Fences are priced by the metre for one side, at $5–$19, so washing both faces doubles the length billed. Flats are 14.8% of Wollongong dwellings (ABS 2021 Census); in a unit block the shared walls and driveways belong to the owners corporation, so the strata manager books that wash. A low-rise commercial building of up to three storeys runs $430–$2,150.
How to Save Money on Pressure Washing Cost in Wollongong
Pressure Washing Cost in Wollongong by Job Size
Say a three-bedroom home has a path, a paved pool surround and two rendered walls, each within the row's roughly 30 square metres, to clean. The rows run $110–$240, $160–$410 and $130–$325 each, so the lot comes to $530–$1,300.
What moves a job of that size in Wollongong is the weather and the building. Wet summers grow mould on shaded paving, damp walls and decks, which adds the mould row at $325–$970, and a two-storey exterior takes the house wash from $270–$755 to $485–$1,200. A unit block's shared walls are booked through the strata manager.
Pressure Washing Cost in Wollongong: What the Quote Should Include
Wollongong outdoor areas are priced piece by piece, so a quote for a three-bedroom home should list the path, paving, walls, fence and deck individually. Wet summers also grow mould on shaded paving, damp walls and timber decks, so the treatment belongs on its own line.
- The path at $110–$240, pool paving at $160–$410 and any single wall at $130–$325 each listed as a piece with its own size.
- Fences counted in metres, with a note on whether one face or both are washed, since washing both faces counts the length twice.
- Mould on shaded paving, damp walls and decks treated under a line at $325–$970, with the inhibitor at $54–$160 added where growth returns.
- The walls and eaves of a single-storey house soft washed at $325–$700, with the render and paint named.
- A two-storey exterior at $485–$1,200, with ladders, extension wands or access gear for the upper walls named.
- The roof at $325–$1,400, with how the crew stays off the tiles and how the surface coating on them is protected.
- In a unit block, shared walls and driveways quoted through the strata manager or owners corporation, not by one owner.
- A low-rise commercial building read against $430–$2,150, with the number of storeys written down.
- Walls washed ahead of the painters, with the dates written so the surface is dry when the paint goes on.
