## What affects Pressure Cleaning cost

- **Surface type:** The base rate changes depending on whether the job is for a driveway, house washing exterior, or roof cleaning. Driveways start at $5 per m², house exterior cleaning is $6 per m², and roof cleaning is $8 per m².
- **Level of dirt and staining:** Light dirt uses the standard rate, while heavy mould or oil increases pricing by a ×1.4 multiplier. This is common where surfaces need more treatment time or a more careful cleaning process.
- **Building height and access:** Jobs involving two storeys use a ×1.2 multiplier because access equipment, setup time, and safety requirements are higher. This often affects house washing and exterior wall cleaning more than ground-level areas.
- **Minimum job charge:** If the calculated total comes in below the minimum service fee, the price defaults to $180 AUD. This is most relevant for small pressure washing jobs where the m² total is low.
