Expect to pay between $0.10 and $0.50 per square foot for professional pressure washing, or about $50 to $100 per hour, depending on your project's size and complexity. Flat surfaces like driveways and patios are often more affordable to clean than intricate surfaces like siding or roofs.

You can charge anywhere from $50 to $100 per hour depending on your location, the size of the job, and the equipment you'll need to complete it. Price per square foot strategy works best if you're working on a property that requires pressure washing for multiple surfaces.
