3 Pricing Strategies

1. Pricing per Square Foot

The average rate of pressure washing per square foot varies per region. However, the usual estimate is between $0.08 and $0.35 per square foot. The price is also subject to increase due to other factors. 

CostHelper says that heavy stains, grimes, mold, and dirt are some of these. In the event of stubborn surface dirt, power washers can charge $0.40 to $0.80 per square foot. 

To compute for the square footage, multiply the surface’s length and width, then multiply the result to 1.35. Use a laser distance measurer for more accuracy. 

2. Pricing per Hour reports that the average pressure washing rate per hour is between $60 to $100. For example, a 1,000 square meter courtyard takes about five hours to power wash, making the cost between $300 to $500. 

Here are more examples:

Average Hour to Clean
​Price Range
2,000 sq. m house
~ 2 hours
$450 to $800

~ 2-3 hours
$120 to $300

Sidewalk, driveway
~ 1 hour
$60 to $100

Porch, Patio, Deck
~ 1-2 hours
$60 to $200

Take note that demand, competition, and even weather influence pricing as well. 

3. Flat Rate

Some washers offer flat rate pricing. They are familiar with the average fees and know the kind of work required for particular dirt or stains. Their method is adding cost over the standard price for the total area in square feet.

Another tip to remember: Consider other elements such as cleaning chemicals and water temperature (hot or cold). Do not forget about the overhead costs too! They are usually at $40 hourly.


Use the standard rates for power washing services to calculate the overall cost. Apply the linear or square footage, materials, and overhead prices as well. Likewise, you may also use average rates.

Here is another way as suggested by

(Materials price x 2) + Cold or Hot Water Cleaning fee = Power washing service price

Water cleaning rates:
    Hot water: between $55 to $60
    Coldwater: between $45 to $50

Ex. The total materials cost for power washing a rooftop is $300. So, multiply 300 by 2, 
then add $50 because you will need cold water cleaning.
        $600 + $50 = $650 project cost estimate
