Pressure Washing Estimate Calculator

How Pressure Washing Contractors Estimate Jobs

Pick the surface type before you enter square feet. House wash production differs from driveway degreasing and wood deck soft wash.

Square footage on a ranch home is wall area, not floor plan. Measure perimeter times average story height or use siding square numbers from a material takeoff.

Stories add time for ladder moves and downstreaming setup. The tool applies a simple factor on house wash hours when you enter two or three stories.

Driveway and parking lot jobs use flat square feet from plat length times width. Oil spots need pretreat time outside the base production rate.

Deck work is slower per foot than concrete. Wood requires lower pressure and often a dedicated detergent. Use a lower square feet per hour in your field.

Commercial nights and weekends might bill the same math with a higher labor rate. Enter the rate you charge after hours.

Chemical cost is the sum of surfactant, sodium hypochlorite, and degreaser you expect to pump on the job. Use your supplier invoice, not a chart from a forum.

Setup hours cover tape, plastic on plants, and pulling hose lines. Use what your last few tight homes took as the starting point. Add more on windy days with delicate landscaping.

Water fees apply when you tie into a metered hydrant or pay for tank water on rural jobs. Leave zero on most suburban homes.

Square feet per hour should come from timer logs on similar jobs. Track rinse only passes separate from dwell and scrub steps.

Labor rate includes workers comp, fuel, and payment on the rig. For example, a $30 wage plus $20 an hour in truck cost puts about $50 in the rate field. Materials markup catches broken nozzles and extra hose.

Profit margin divides out through subtotal divided by one minus margin percent on the suggested bid. Price per square foot helps you compare against coupon mailers. Know your floor before you match a cheap per foot price in a mailer.

Walk the property for fragile screens, old paint, and active bee hives before you promise same day service. Roof soft wash jobs use lower pressure and more chemical dwell time. Drop sq ft per hour and raise chemical cost compared to flat concrete.

Fleet washes bill per vehicle with a separate production rate. Duplicate this worksheet per truck when you price commercial yards.

Graffiti removal needs pretreat products not used on a standard house wash. Add chemical cost before you match a basic wash price.

Reclaimed water setups add setup hours in municipalities that require runoff control. Document that time in the proposal letter.

Multi building HOA contracts should be priced per building then summed. Run the calculator once per structure when elevations differ.

Gum removal on sidewalks adds pretreat time not counted in open square footage pacing. Increase setup hours when retail walks are spotted with gum. Lift rental on three story wood siding belongs in materials or setup, not hidden inside production rate alone.

Flat work degreasing on restaurants needs hog water recovery time in some towns. Add setup when the health department requires it.

Soft wash on render and stucco runs slower than vinyl lap siding. Lower sq ft per hour and raise chemical cost on masonry finishes.

Storefront mornings with pedestrian traffic need cone and barricade setup. Count that time in setup hours before you quote rush jobs.

Dusty new construction cleans on masonry need a rinse pass before detergent. Add setup hours when the builder has not pre rinsed the facade.

Parking garage oil separators require compliant disposal fees in some counties. Add water fee when you haul reclaim water off site.
