Knowing how to bid a pressure washing job can make the difference between profit or loss, between winning or losing jobs, between slave wages or a comfortable living. With careful calculations, you won't short-change yourself or charge too much. There are two common methods for figuring out how much to ask for when bidding on a pressure washing job.

Items you will need

  • Measuring tape or wheel
  • Pen
  • Paper
  • Calculator

Time & Materials

Step 1

Have what exactly is expected of you clearly described to you. Have it put into writing by whomever is entering into an agreement with you or write it down and have him sign it.

Step 2

Walk around the job site to get a feel for any difficulties, noting additional time added toward job completion. Annotate each step involved in completing the power washing job.

Step 3

Add up the amount of time the job will take, starting from arrival at the job site to departure from it. Include additional time away from the job site, which will be directly used for completion of the job.

Step 4

Annotate what cleaning materials are required for the job. Figure out your total materials costs, including cleaning solutions, chemicals and gas for the power washer.

Step 5

Set your hourly rate or total cost of labor for the job. Combine the total cost for your labor and the total cost of the materials used on the job.

Square Footage

Step 1

Measure the square footage of each surface that will get power washed. Do so by measuring length by width, or width by height.

Step 2

Add together the measurements for like surfaces. Add the square footage together for all surfaces, both like and unalike. Annotate any difficulties to the pressure washing job that are beyond common difficulties.

Step 3

Set a rate for each square foot pressure washed, and if necessary, for different types of surfaces or difficulties in reaching and pressure washing surfaces. Annotate any difficulties to the pressure washing job that are beyond common difficulties, and include an additional flat rate for completing such difficulties.
