Pressure Washing Cost Calculator
Updated · By the CalculatorDash editorial team · How we check our maths
Quick answer
Most residential pressure washing jobs cost $150–$500, and many land around $250–$400. Contractors often charge about $0.15–$0.40 per sq ft for driveways and $0.20–$0.45 per sq ft for siding, with extra for oil stains, second-storey work or soft-washing.
How this calculator works
Pressure washing is priced per square foot of surface, with the rate depending on what is being cleaned. Concrete takes high pressure and moves quickly; siding and roofs need low-pressure soft-washing with detergents, which costs more per square foot; wood needs care so it is not gouged.
This calculator multiplies area by the surface rate, adds a premium for stains and height, optionally prices sealing, and applies a minimum so small jobs still pay for setup and travel.
The formula
- Cleaning
- area × surface rate × stain factor × height factor
- Sealing
- area × sealer rate (if selected)
- Price
- the larger of (cleaning + sealing) and the minimum charge
Worked example
An 800 sq ft driveway at $0.22 per sq ft is $176. With oil-stain treatment (+25%) it becomes $220. Adding sealer at $0.60 per sq ft brings the job to $700.
Tips
- 01Bundle the driveway, walkway and patio into one visit to make the minimum charge work for you.
- 02Offer a recurring annual or twice-yearly cleaning plan to customers you have already served.
- 03Photograph surfaces before and after for your portfolio and to avoid disputes over pre-existing damage.
Frequently asked questions
How much does it cost to pressure wash a driveway?
Driveway cleaning is commonly quoted at about $100–$300, or $0.15–$0.40 per sq ft, depending on stains and size.
How much does it cost to pressure wash a house?
Washing the siding on a one- or two-storey home is commonly quoted at roughly $250–$800, depending on size, height and how dirty it is.
What is the difference between pressure washing and soft washing?
Pressure washing uses high-pressure water for hard surfaces like concrete. Soft washing uses low pressure plus cleaning solutions for siding and roofs, which can be damaged by high pressure.
What minimum should I charge for pressure washing?
Many operators set a minimum of $100–$200 so short jobs still cover travel, setup and equipment costs.
