How to Start a Pressure Washing Business

By the Strivue team · Updated October 16, 2026

Starting a pressure washing business takes less capital than most trades, but it is not "buy a machine and knock on doors." The jobs that go wrong are the ones where the owner skipped insurance, ignored where the wash water goes, or priced from a guess. This guide follows the order you will actually run into things.

Decide what you will sell first

Pick two or three services and get good at them before adding more. A common starting mix:

Flatwork: driveways, sidewalks, patios, and pool decks. Quick to learn, and the before-and-after difference is easy to show.
House washing: siding, usually with a low-pressure "soft wash" method (cleaning solution applied at low pressure, then rinsed), because high pressure can damage siding, push water behind it, or strip paint.
Commercial exteriors: storefront sidewalks, dumpster pads, and parking areas. Better recurring revenue, but more paperwork and tighter wash-water rules. See how to find commercial pressure washing clients.

Match your first mix to the equipment you can afford and the customers within a short drive of home.

Set up the legal basics

The sequence most new owners follow:

Choose a structure. A sole proprietorship is the simplest. An LLC adds legal separation between you and the business. The SBA's guide compares the options (see Sources); the right one depends on your state and your risk.
Get an EIN. The IRS issues Employer Identification Numbers at no charge. You will want one for a business bank account and for commercial customers who ask for a W-9.
Open a business bank account so business income and expenses stay out of your personal account.
Check licenses and permits. Requirements vary widely by state, county, and city. Some places only require a general business license; others regulate certain exterior-cleaning or chemical work. Your city or county business office and your state licensing board can tell you what applies to the services you listed above.
Ask about sales tax. Whether cleaning services are taxable depends on the state. Your state revenue department publishes the rule.

Get insured before the first job

Pressure washing causes property damage in ordinary ways: etched concrete, damaged window seals, water forced behind siding, stripped paint, and overspray onto cars and plants. Insurance keeps one bad job from ending the business.

General liability covers damage to a customer's property and injuries to third parties. Commercial customers usually ask for a certificate of insurance (COI) before you can work on site.
Commercial auto may be needed if you use a vehicle or trailer for the business, because personal auto policies often exclude business use.
Workers' compensation rules apply once you hire, and the rules for helpers and subcontractors vary by state.

Talk to an agent who writes policies for contractors, tell them exactly what you will clean (including chemicals), and ask what is excluded. The exclusions matter more than the premium.

Plan for wash water

This is the part new owners skip. Storm drains in streets and parking lots usually lead to local waterways rather than a treatment plant, so soapy, oily, or debris-laden wash water going into one can create a violation and a bill. Rules are local. As one example, a city stormwater guide from Monroe, North Carolina treats wash water entering a storm drain as an illicit discharge, asks cleaners to plan disposal with the client before starting, lists containment tools such as berms, pumps, and vacuums, and allows sewer discharge only after pretreatment and contact with the water utility.

Call your city or county stormwater office and your local sewer utility and ask what applies to mobile cleaning. Write down who you spoke to and what they said.
Ask whether the rules differ for plain-water cleaning versus cleaning with detergents.
Budget for containment gear (berms or mats and a wet vacuum) before taking restaurant, fuel-station, or parking-lot work, where oil and grease are likely.
Read every cleaning product's label and safety data sheet, and never mix chemicals.

Buy equipment for the jobs you will actually do

Start with what your first two services need, not a full rig.

Pressure washer: look at both pressure (PSI) and flow (GPM). Flow is what moves dirt off a large surface quickly.
Surface cleaner: a rotating attachment that makes flatwork faster and more even than a bare wand.
Hoses, nozzles, and extension wands in good condition. Worn fittings are a common source of downtime.
A soft-wash setup if you plan to offer house washing.
Water supply: a customer's spigot works for many jobs; a tank helps where water is not available on site.
Protective gear: eye protection, gloves, and non-slip footwear at minimum, plus protection suited to the chemicals you use.
Transport: a truck or trailer setup you can load and secure quickly.

Most items come in a cheaper and a more durable version. Spend on durability for the equipment that touches every job.

Price from your costs, not from a guess

Three common ways to price are per square foot, per job (flat), and per hour. Whichever you use, check it against your own costs first.

Time a few jobs. Record square footage and minutes on your first jobs so you know how much you actually clean per hour, including setup, travel, and rinse-down.
Add up the real cost of an hour: labor (including your own time at a fair wage), chemicals, fuel, equipment wear, insurance, vehicle, and a share of overhead such as software and marketing.
Set a minimum charge so a small job still covers travel and setup.
Compare with the local market. Look at competitors' published prices and request a few quotes. Your price should be defensible, not the lowest.

Illustration only, not a market rate: if a driveway takes one person 90 minutes including setup and travel, and your all-in cost for an hour of work is $40, your break-even is $60 before any profit. Whatever you quote has to sit meaningfully above your own number.

Win your first customers

Proof and proximity win the first jobs: before-and-after photos, neighbors who can see the result, and fast replies. The specific tactics are in how to get your first pressure washing customers.

Keep records from day one

Even with five customers, write down who they are, what you quoted, what you did, and when to follow up. Before-and-after photos protect you if a customer disputes damage. A spreadsheet works at the start. When you are juggling quotes, jobs, and repeat customers across a small team, software helps. Strivue is early-stage software for small field-service teams, covering customers, jobs, quotes, and a map-based prospect pipeline.

Mistakes that cost new owners money

Underpricing small jobs so setup and travel eat the profit.
Quoting without a written scope (what is included, what is not, and whether water and access are available).
Using too much pressure on wood, soft siding, or older mortar, and skipping a test spot first.
Working without insurance, then being unable to take commercial work that requires a COI.
Ignoring where the water drains.
Depending on one customer type or one lead source.

Frequently asked questions

Do I need a license to start a pressure washing business?

It depends on where you operate. A general business license is common, and some states or cities add contractor-licensing or chemical-handling rules. Check with your city or county business office and your state licensing board, and keep what they tell you in writing.

How much does it cost to start?

It depends mainly on whether you begin with a basic residential setup or a full trailer rig, and on your insurance quotes. Price the equipment list above locally and get an insurance quote before you commit; those two numbers cover most of the startup cost.

Can I start part-time?

Yes, many owners start on evenings and weekends. Insurance, a written quote process, and a reliable way to schedule and follow up matter as much part-time as full-time.

Should I start with residential or commercial work?

Residential jobs are quicker to win and easier to learn on. Commercial work pays through recurring contracts but asks for insurance certificates, paperwork, and tighter wash-water control. Many owners start residential and add commercial once they have proof of work.
