How to write a pressure washing invoice

The surface sets the rate, so the invoice lists surfaces

The Housecall Pro pricing guide describes four ways to price: per square foot, a flat price per surface, hourly, and contract pricing for recurring work. Whichever you quote, write the invoice by surface with the area beside it. A line reading "driveway, concrete, 900 sq ft" can be checked with a tape or a satellite photo. "Pressure washing, $986" cannot, and it is the line that turns into a dispute when the customer decides their driveway is smaller than you think.

From the Housecall Pro pressure washing pricing guide, updated October 2026. One software company's figures; your market sets your rate.

The spread between surfaces is the useful part of the table. A roof costs more than a driveway because the method, the chemistry and the risk are different, so a house with siding, brick and a deck is three lines, not one.

Pressure washing invoice example, filled in

A residential job: driveway, walk and patio, and a two-story vinyl house wash, with second-story access and a rust treatment as their own lines. Rates are samples within the published ranges.

Five lines total $986. The house wash is priced on wall area, 1,800 square feet, not the house footprint, which is the number customers most often misjudge. The rust line says it may not lift fully, which is cheaper to write now than to argue later.

Name the method on the line

If you soft wash siding at low pressure with a cleaning solution and run a surface cleaner over concrete, the invoice should say which went where. The method is part of what you are selling, and it is part of the answer if something goes wrong, so write it on the line: "soft wash, low pressure" next to the siding, "surface cleaner" next to the drive. A customer who later finds a streak on the siding has a different conversation with you when the invoice shows you did not point a turbo nozzle at it.

Minimums and add-ons

The Housecall Pro guide says small jobs still carry travel, setup and breakdown time, and that without a minimum they often become unprofitable; it adds that same-day or after-hours work should carry a higher base fee. Print your minimum on the estimate. When it applies, show it as a "minimum service charge" line, never as an inflated square footage that a customer can measure and catch.

The same guide lists the adjustments worth keeping visible: heavy oil or grease, oxidation treatment, rust stain removal, soft-wash chemical upgrades, second-story access, restricted water supply and emergency scheduling. Each takes time or product the base rate does not cover, and each is easier to defend as a named line than as a mysterious uplift. Water supply deserves a sentence of its own on the estimate. If you rely on the customer's faucet and it fails halfway through, the paper should already say whose problem that is.

Condition notes are half the invoice

Pressure washing is the cleaning trade where the cleaning can cause the complaint. Water at force finds cracks in old concrete, lifts loose paint and gets behind failed window seals. Walk the surfaces with the customer, photograph anything already wrong, list it on the estimate and repeat a short version on the invoice. That sentence turns "you cracked my driveway" into a conversation about a crack you both looked at on Tuesday.

Do the same with results you cannot promise. Rust, oil and organic stains that are years old sometimes fade instead of vanishing. Say so on the line before you start.

Where the wash water goes

Commercial customers increasingly ask, and the answer can be a billable line. The Ohio EPA guidance for power washers says wastewater generated by power washing is considered industrial wastewater, that it cannot go into a storm sewer, that biodegradable soap does not change that, and that discharge to a sanitary sewer needs permission from the local treatment plant; with no sanitary access, the water must be collected. The document labels itself guidance and not law, and other states and cities set their own rules, so check yours. At the federal level, EPA's stormwater fact sheet on vehicle maintenance and washing (EPA-832-F-21-032F, February 2023) tells local governments to teach residents and business owners that storm drains lead directly to local waterways, not to treatment facilities, and cites Fairfax County, Virginia, as a place whose ordinance bars unpermitted commercial wash water from the storm drain system. A City of Archdale, North Carolina flyer hosted in EPA's outreach toolbox gives the practical version: block storm drains before pressure washing and collect the water with a liquid vacuum for proper disposal. Where you berm, vacuum and haul the water, that is equipment and time, and it belongs on the invoice as a recovery line.

Commercial contracts, and a state that taxes the work

Storefronts, drive-throughs and dumpster pads buy on a schedule, and a monthly invoice that names the visit number and the agreement saves requoting. Tax is where commercial work gets attention. The Texas Comptroller says pressure washing buildings, sidewalks and parking lots is taxable as building or grounds cleaning, and the Nebraska Department of Revenue lists sandblasting or power washing building exteriors among taxable building cleaning services. Other states treat it differently, so check with your state revenue department before you set the tax line.

Three lines total $500, sales tax at a sample 8.25% is $41.25, and $541.25 is due. The recovery line is what lets the store manager tell a landlord or inspector where the water went.
