Short answer
As a guide, a professional house wash on a single storey Brisbane home starts from about $550, and a two storey home starts from about $660. The final price depends on the size of the home, the wall types, how much mould and grime has built up, and access around the house. A free quote confirms the exact figure before any work starts.
Key points
- Single storey homes start from $550 and two storey homes from $660 (Waterworx prices, November 2026).
- Size, storeys, mould build-up and access move the price the most.
- A soft wash uses low pressure and a cleaning treatment, so paint, render and timber are not damaged.
- Adding the roof, driveway or decks on the same visit is usually cheaper than separate bookings.
- Seniors Card holders get 10% off with Waterworx.

What a house wash includes
- External walls, from ground level to the eaves
- Eaves, soffits and fascias, where cobwebs and mould collect
- Window frames and sills (not a full window clean)
- Front entry, verandahs and balconies that are part of the home
- A rinse of garden beds and paths around the home afterwards
Driveways, paths, decks, fences and the roof are separate jobs, but booking them on the same visit saves a second set-up.
What pushes a house washing quote up or down
| Factor | Why it matters |
|---|---|
| Size and storeys | More wall area and height means more time and, on two storey homes, extra safety gear. |
| Wall types | Timber, render, brick and fibre cement each need a different method and pressure. |
| Mould and grime | Heavy black mould on shaded walls can need a longer dwell time or a second treatment. |
| Access | Steep blocks, tight side paths and high set Queenslanders take longer to set up and work around. |
| Extras on the same visit | Adding the roof, driveway or decks shares the set-up, so each job costs less than on its own. |

Why a soft wash, not high pressure
High pressure on painted walls, render and timber can strip paint, etch the surface and force water behind cladding. A soft wash uses a cleaning treatment that kills mould at the root, then a low pressure rinse. The walls come up clean and the mould takes longer to come back.
How often should a Brisbane house be washed?
Most Brisbane homes look their best with a wash every 12 to 24 months. Homes near the river or the bay, under trees or on the shady south side grow mould faster and often need it every year.
A wash is also worth doing before selling or leasing, before repainting (paint will not bond to a dirty wall), and at the end of a lease.
