Step-by-step pressure washing estimating workflow
1. Start with the service type
A driveway wash, house wash, deck cleaning, fence cleaning, gutter brightening, and roof soft wash can have different production speeds, chemical needs, and risk.
2. Measure the square footage
Use square footage or linear footage as the estimating base, but do not let area be the only input. Access, soil level, and cleanup often change the job cost.
3. Add labor cost
Estimate crew hours from production speed, setup, cleanup, and communication time. Multiply the hours by your loaded labor rate.
4. Add materials and chemicals
Include degreaser, surfactant, soft wash mix, fuel, rinse water handling, and any job-specific supplies.
5. Add travel and setup
Short jobs still require driving, unloading, hose setup, customer communication, and cleanup. These costs should not disappear on small estimates.
6. Add overhead
Account for insurance, equipment wear, admin time, marketing, software, bookkeeping, and other business costs that support every job.
7. Choose a target profit margin
After direct cost and overhead are included, price the job to the margin your business needs. A 45% margin target means the customer price must be high enough that cost remains 55% of revenue before rounding and package choices.
8. Apply a minimum job price
A minimum job price protects your trip, setup, and communication time. If a calculated driveway wash comes out below your minimum, the minimum should win before any discount is applied.
9. Turn the estimate into a customer quote
The internal worksheet can include labor, materials, overhead, and margin. The customer quote should show the scope of work, line items, Good/Better/Best options, exclusions, expiration date, total price, and acceptance instructions.
Example estimate
For a 1,200 sq ft driveway, you might start with a $0.22 per sq ft area check, then compare that against labor, materials, travel, equipment overhead, and a target margin. If the area check is too low to protect margin and minimum job price, use the higher estimate before sending the customer quote.
Pressure washing estimating FAQ
How do I estimate a pressure washing job?
Start with the service type and square footage, then add labor, materials, travel, overhead, minimum job price, and target profit margin before turning the result into a customer-ready quote.
What is the biggest pressure washing estimating mistake?
The biggest mistake is quoting from square footage alone without adding setup time, travel, chemical cost, equipment wear, overhead, and a minimum job price.
Should I show the customer my margin?
No. Keep margin, labor cost, and internal assumptions private. The customer estimate should show scope, line items, package options, terms, and the final price.
