Direct answer. Price a pressure-washing job by converting the scope into expected crew time, worker hours and direct cost, then protect the price for overhead and target margin. A per-square-foot rate can be a useful quoting unit, but it should not override the economics underneath the job.
1. Define the billable unit
Choose a unit that fits the service—square feet, linear feet, each, hour or flat job. Measure the quantity consistently so you can compare future jobs on the same basis.
2. Estimate production
A production rate converts quantity into crew hours. If the service needs 1,000 units and the crew can complete 500 units per crew hour, the base time is two crew hours before difficulty adjustments.
3. Separate crew hours from worker hours
Crew Hours describe elapsed crew time. Worker Hours equal Crew Hours × Crew Size. Two crew hours with a three-person crew represent six worker hours of labor cost.
4. Calculate direct cost
Add burdened labor, chemicals or supplies, equipment, trip or fuel and other direct job cost. If difficulty increases the amount of time and applicable variable cost, reflect that explicitly rather than hiding it in a vague markup.
5. Protect the economic floor
A target-margin floor can be calculated as Direct Cost ÷ (1 − Overhead % − Target Net Margin %). Apply the business’s minimum job charge and compare that floor with the current ratebook reference.
6. Use minimums intentionally
Small jobs still consume mobilization, setup, travel and administrative time. A line or job minimum should be a deliberate business rule, not a random number added after the quote looks too low.
7. Compare estimate with actual
Pricing is only the first decision. After the job, compare actual labor, supplies or equipment and other costs with the estimate. A rate that looked competitive can still be wrong for your operation if production or direct cost repeatedly misses the assumption.
