Pressure Washing Prices Per Square Foot: A Practical Chart
Pricing per square foot is popular because it is fast to quote and easy for a customer to understand. It is also the quickest way to lose money if the surface is filthy, the access is bad, or you never checked the number against your hourly cost. Here is how to use square-foot pricing without getting burned.
Typical per square foot rates
| Surface | Common rate | Notes |
|---|---|---|
| Concrete driveway | $0.10 – $0.25 / sq ft | Surface cleaner speeds this up dramatically |
| Sidewalk or walkway | $0.12 – $0.30 / sq ft | Narrow strips take longer per foot |
| Patio or pool deck | $0.15 – $0.35 / sq ft | Furniture moving and edging add time |
| House wash (soft wash) | $0.15 – $0.40 / sq ft | Usually priced on footprint or per storey |
| Wood deck | $0.25 – $0.60 / sq ft | Low pressure, careful technique, more time |
| Roof (soft wash) | $0.30 – $0.75 / sq ft | Pitch, height, and safety gear drive the price |
| Commercial flatwork | $0.06 – $0.15 / sq ft | Volume rate; large open areas clean fast |
Ranges reflect commonly quoted contractor rates. Adjust for your market, surface condition, and access.
How to measure quickly
- 1Use a measuring wheel or a satellite map tool for driveways and flatwork.
- 2For a house wash, measure the footprint perimeter and multiply by wall height per storey.
- 3Break irregular areas into rectangles and add them together.
- 4Round up to the next 50 square feet — you will not regret the cushion.
Always sanity-check against your hourly rate
A square-foot rate is only correct if it produces at least your required hourly revenue. Run the check before you send the quote.
(Square feet × rate) ÷ estimated hours = effective hourly rate
1,000 sq ft × $0.18 = $180. At 2.5 hours on site that is $72/hour — fine if you need $70, a loss if you need $95.
The condition multiplier
A lightly soiled driveway and a fifteen-year-old oil-stained driveway are not the same job at the same rate. Apply a 1.25x to 1.75x multiplier for heavy organic growth, rust, or oil, and say so in your quote notes so the customer understands what they are paying for.
When not to price per square foot
- Small jobs where the trip costs more than the area — use your minimum service call
- Anything with heavy staining, rust removal, or gum removal
- Second-storey or roof work where safety setup dominates the time
- Sites with no water access, requiring a buffer tank and extra logistics
- Restoration-style jobs where results depend on chemistry, not coverage speed
Use square-foot rates as a quoting shortcut, not as your pricing model. The model is your cost per hour. The rate is just a fast way to reach it.

How much is pressure washing per square foot?
Most residential pressure washing falls between $0.10 and $0.35 per square foot, with decks and roofs running higher because they take more time and care.
Is square footage the best way to price a driveway?
It is the fastest, and it works well for clean, open concrete. For heavily stained or awkward driveways, price by time and materials instead.
