How Much Does House Washing Cost in Adelaide?
House washing in Adelaide typically costs between $300 and $600 for a single-storey home and between $500 and $900 for a double-storey home. The price depends on the size of the house, the number of storeys, how much access the operator has, the wall material and how heavy the algae or mould growth is. Render and weatherboard take more care than face brick, so they usually sit at the higher end of the range.
Key takeaways
- Single-storey Adelaide homes usually land between $300 and $600 for a full soft wash.
- Double-storey homes run around $500 to $900 because upper walls take more setup and time.
- Render and weatherboard cost more than brick because they need a slower, gentler pass.
- A cheap high-pressure blast is a false economy: it regrows in weeks and can crack render or strip paint.
- We connect you with vetted Adelaide operators who quote for free, so comparing prices costs nothing.
The indicative price range for an Adelaide home
For a full exterior soft wash, most single-storey Adelaide homes fall between $300 and $600. Most double-storey homes fall between $500 and $900. These are indicative figures, not a quote, because the final price always turns on the specifics of your home.
A double-storey home is not simply twice the price of a single-storey one. The added cost comes from safely reaching the upper walls, which takes more setup, and from the extra care needed when those walls are render or weatherboard rather than brick. A larger footprint, awkward access and heavy growth all push the number up within these bands.
What pushes the price up or down
When an operator quotes your home, they are pricing time and risk, not just wall area. A single-storey brick home with clear access on all sides is quick and predictable. A double-storey rendered home wedged against a boundary fence with a garden bed in the way is slow, careful work, and it prices accordingly.
- Storeys: upper walls need safe access and more setup, so double-storey homes cost more.
- Wall material: render, cladding and weatherboard need a gentler, slower pass than face brick.
- Access: narrow side passages, boundary fences and established landscaping all add time.
- Growth level: a wall covered in black mould or lichen needs stronger treatment and longer dwell than a lightly dusty one.
- Extras: gutter faces, eaves, soffits and adjoining structures can be bundled in and shift the price.
Why the cheapest quote is often the most expensive
It is tempting to take the lowest number, especially when someone offers to blast the whole house for a flat, cheap rate. That is usually the quote to be most careful with. High pressure on render, cladding or painted walls does not just fail to last, it can cause damage that costs far more than the wash to repair.
There is also the regrowth problem. A blast knocks the surface film off but leaves the algae roots behind, so the growth returns within weeks. A proper soft wash kills the growth at the root and stays clean for years. Paying $400 once every few years is cheaper than paying $250 several times a year and risking a render repair on top.
The value in comparing quotes is not finding the lowest number. It is finding an operator who will soft wash your walls correctly, at a fair price, so you only pay for it once.
