Per square metre vs flat rate pricing
Both models work — the key is knowing when to use each. Per-square-metre pricing is transparent and easy for clients to compare. It works well for large, uniform surfaces like driveways and car parks where you can measure quickly. Flat-rate pricing works better for smaller residential jobs where measuring feels awkward and clients just want a single number. Many operators use per-sqm for quoting internally (so they know their margins) but present a flat price to the client.
Typical pricing for residential work
These are common ranges for Australian metro areas in 2026. Regional rates may be slightly lower, but your travel costs are often higher.
- •Concrete driveway (single): $150–$300 depending on size and condition
- •Concrete driveway (double): $250–$450
- •Paved or tiled patio: $100–$250
- •Timber deck (wash and prep): $150–$350 — pricing should reflect the care needed to avoid damage
- •Roof wash (single storey): $400–$800 depending on pitch, material, and access
- •Roof wash (double storey): $600–$1,200 — higher risk and setup time justifies the premium
- •House exterior wash: $250–$500 for a standard home
- •Pool surrounds: $100–$250
- •Per-square-metre rate: $3–$8/sqm for standard concrete, $6–$12/sqm for soft-wash surfaces
Chemical costs and how to factor them in
Chemicals are a significant cost that many operators underestimate. Sodium hypochlorite (liquid chlorine) for soft washing, surfactants, rust removers, and degreasers all add up. On a typical driveway job, chemical costs run $10–$30. On a full roof soft wash, they can reach $40–$80. Factor these into your per-job cost and review your chemical spend monthly. Buying in bulk from a chemical supplier rather than retail saves 30–50% on your biggest recurring expense.
Setting a minimum call-out fee
Never drive to a job site for less than it costs you to get there. A minimum call-out fee covers your travel time, fuel, equipment setup, and the opportunity cost of not being on a higher-value job. For most Australian pressure washing businesses, a minimum of $150–$200 is reasonable. This ensures that even a small job like a single patio or set of stairs is worth your time. Communicate the minimum clearly when quoting — clients understand once you explain the setup involved.
Pricing commercial and strata work
Commercial work — car parks, loading docks, shopping centres, and strata common areas — is typically priced lower per square metre than residential because the areas are larger and more accessible. However, the total job value is higher and the work is often recurring. Commercial rates generally range from $2–$5 per square metre. Quote based on total area, frequency (monthly, quarterly, annually), and any after-hours requirements. Strata managers often prefer a fixed monthly retainer covering scheduled washes throughout the year.
