How to Estimate Your Pressure Cleaning

It is not an easy task to estimate for your power washing jobs. There are numerous factors to note, such as local demand and competition. Cold weather climates might give rise to seasonal demand for pressure cleaning.

Power washers in places with much competition will require monitoring on the average prices.

Follow the five steps listed below to simplify the estimation of your pressure cleaning needs:

  1. Measure the Space

Majority of pressure cleaning is estimated depending on the size of the area to be washed, whether in square footage or linear footage, according to professionals. Checking property in person before an estimate is sent is important to determine the conditions of the site personally. Make sure you identify the actual service you wants to be done and if there are any special services or repair work you need.

  • Square Footage: Project estimates that are determined based on square footage include driveways, decks, parking lots, sidewalks, roofs, fences, siding, garage floors, and commercial cleaning. Find out square footage by calculating the length and width of the area. Make good use of a laser distance measurer. Find the product of the length by the width. Then use 1.35 to multiply that number to determine the approximate square footage.
  • Linear Footage: Project estimates that are determined based on linear footage include houses and boats. You just measure the length of the building, leaving the width or thickness measurements. You can then base your charge on a linear foot. Linear feet are charged at an expensive rate than square footage.

Tip: If you know you are not experienced in this task, allow an expert to do it for you.

  1. Choose a Pricing Strategy

Professionals normally estimate household jobs based on one of the three pricing techniques:

  • Per square foot or linear foot
  • Per hour
  • Flat rate

Pricing by the square or linear foot makes it convenient to bid on various sizes and shapes of lots or structures. Hourly pricing ensures you are paid for each hour worked. Flat rate pricing is helpful if you have experience in pressure cleaning and already know the pricing for various jobs and how several factors the price.

Using this method, you have to determine the rough price depending on the square footage and then add your markup to it. More earning is made possible with flat-rate pricing but it requires an experienced professional to handle it correctly, as reported by the Houston Chronicle.

  1. Price based on the Project

Service also impacts rates. Below are some standard rates based on the country’s average to assist you to estimate your pressure cleaning job, whether in the parking lot or a house.  


  • $90  to $275 flat rate for exterior
  • $0.75 to $1.25 per linear foot (one- story house)
  • $1.75  to  $2.25 per linear foot (double- story house)


  • $100 for single story
  • $135 for two floors
  • $200 for three floors


  • $5 per linear foot for just the bottom
  • $10 per linear foot for the entire boat


  • $0.20 per square foot
  • Double or trice the fee for roofs with sloppy pitches

Driveways and Sidewalks

  • $60 to $150 flat price (based on size)
  • $0.08 to $0.14/ square foot

Fences, Decks, and Siding

  • $0.20 to $0.25/ square foot

Mobile Homes

  • $50 to $85 flat rate: mobile home (based on condition)
  • $80 to $100 flat rate: double wide (based on condition)

Commercial Cleaning

  • $0.08 to $0.12/ square foot for basic surface cleaning
  • $75 for standard dumpster & $150 for large

Garages, Parking Lots, and Drive Thrus

  • $0.05 to $0.25/ square foot for parking lots and garage floors (based on condition)
  • $10 to $20/ parking space

4. Estimate Materials and Overhead Costs

Extra costs include chemicals for jobs on decks, roofs, and siding. For instance, the cost of chemicals to power wash a roof is about $50. Prices will also vary based on the temperature of water (hot or cold) you use for cleaning.

Overhead is one other cost you should completely add in your estimates, according to Ultimate Washer. Let’s consider some monthly costs based on a 30-hour weekly work.

  • Cleaning supplies: $400 or $3.33 for each hour
  • Vehicle loan: $400 or $3.33 for each hour
  • Car insurance: $125 or $1.04 for each hour
  • Phone and internet: $150 or $1.25 for each  hour
  • Gasoline: $500 per month or $4.17 for each hour
  • Office rent: $900 a month, $9 for each hour (optional)
  • Advertising: $600 or $5.00 an hour
  • Equipment maintenance and fuel: $10 for each hour

Overhead costs are up to $40 per hour alone. You also need to add the company’s personnel salary (assuming $29 per hour at $60,000 per year) and money to save back into the company (say $20,000 or $9.50 per hour). This moves up your rate to $78.50 per hour.

5. Find the Total

Now that you’ve measured your square or linear footage, use the standard rates for the job to calculate the cost, ensuring that materials and overhead are accounted for. Or make use of one of the standard rates mentioned above.

You may consider this other method:

Multiply the cost of materials by 2 and add it to the cost of cold or hot cleaning water to get the project estimate. Coldwater cleaning costs should be around $45 – $50 and hot water cleaning costs should fall between $55 and $60.
