How to start a pressure washing business, from soft wash basics to repeat customers

Pressure washing looks like the simplest trade to start: buy a machine, point it at dirt, get paid. The owners who last learn quickly that the real skills are chemistry, water management and knowing what not to blast. Siding cracks, wood furs, window seals fail, and a rinse that runs into a storm drain can draw attention from the city. This guide covers the work, the legal and insurance basics, equipment, pricing, first customers, the systems to put in place, and how the season changes from Minnesota to Florida.

What does a pressure washing business actually do?

The trade splits into two methods that customers lump together:

• Pressure washing uses high pressure to strip grime from hard surfaces: concrete driveways, sidewalks, patios, pool decks, dumpster pads, some masonry. A surface cleaner (a spinning bar under a round housing) does flatwork evenly and fast.
• Soft washing uses low pressure and a cleaning solution to kill and remove algae, mildew and organic staining on siding, roofs, stucco and painted surfaces. The chemistry does the work; the water just applies and rinses.

Residential work usually means house washes, driveways and concrete, decks and fences, and gutter brightening. Commercial work adds storefronts, drive-thrus, parking garages, fleet washing and HOA common areas, often on a recurring schedule. Roof cleaning is a specialty with more risk and manufacturer guidance to follow: the Asphalt Roofing Manufacturers Association recommends a solution of household bleach (sodium hypochlorite) and water for algae streaks on shingles, and says not to use a power washer or a brush on them. Start with what you can do well and add services once you have the right equipment and training.

What legal and insurance setup does pressure washing need?

Form the business the same way any service company does: pick a structure, file with the state if needed, request the IRS number for free, and open a separate checking account. Our startup checklist has the order. Then deal with the parts specific to washing.

Wash water. The EPA says polluted runoff commonly travels through municipal storm sewers and is often discharged, untreated, into local water bodies. It also notes that runoff "picks up pollutants like trash, chemicals, oils, and dirt/sediment," and that most states are authorized to run the stormwater permit program themselves. On top of that, the EPA says certain local storm sewer operators must hold permits and run stormwater programs to minimize pollutant discharges. Local rules can also restrict what goes down a street drain, especially from commercial sites with oil and grease. Call your city's stormwater or public works office and ask what they expect for residential and commercial washing. On commercial jobs, recovery equipment (berms, drain covers and a vacuum system) is often part of the bid.

Chemicals. Soft wash mixes are commonly built on sodium hypochlorite, the active ingredient in household bleach. Read every label and safety data sheet, wear the protection they call for, and protect plants by wetting them before and rinsing after. When you hire, OSHA's Hazard Communication Standard expects employers to have labels and safety data sheets for hazardous chemicals and to train workers on them.

Licensing. Licensing rules for washing vary by state, county and city. Ask about a general business license, any rules for the cleaning chemicals you plan to use, and whether roof work falls under a contractor license where you work. Check before you take money. This is general information, not legal advice.

Insurance. General liability is a must; think overspray on a car, a blown window seal, dead shrubs, or a slip on a wet deck. Ask your agent in writing whether your policy excludes pollution or chemical damage, what it would take to cover it, and how equipment on the trailer is insured. Our contractor insurance guide goes deeper.

What equipment do you need to start?

Size your setup around two numbers: flow (gallons per minute) and pressure (PSI). Flow does more of the cleaning than most beginners expect; a higher-GPM machine rinses faster and finishes flatwork sooner. Your water supply limits flow, so test a typical customer's spigot with a bucket and a stopwatch before buying a big machine. If spigots cannot keep up, you will need a buffer tank.

A practical starting kit:

• A gas-powered pressure washer with a belt-drive or direct-drive pump, sized to the flow your water source can feed.
• A surface cleaner for concrete.
• A soft wash system: either downstream injection (simple, lower chemical strength) or a dedicated 12-volt soft wash pump and tank for stronger mixes and roofs.
• High-pressure hose on a reel, garden hose, quick connects and a set of nozzle tips.
• Extension wand or telescoping pole, ladder, plant covers, drain covers.
• Personal protection: chemical-resistant gloves, eye protection, boots.
• A trailer or truck bed to mount it all.

Prices vary widely by brand, region and new versus used, so get current quotes from a local equipment dealer rather than trusting an online list. Buy the machine that suits the jobs you can book this season; skid systems with hot water, recovery vacuums and roof rigs can wait until the schedule demands them.

How should you price pressure washing jobs?

Price by the surface and its size, not by the hour. Customers think in "my house" and "my driveway," and you get faster with experience; hourly pricing punishes you for that.

Build your unit rates from your actual cost per hour (labor, chemicals, fuel, a share of overhead and profit), then compare against local companies. Our job pricing guide shows the math. Set a minimum charge so a single small patio still covers the setup and drive, and offer packages (house plus driveway plus walkway) that raise the ticket without adding a second trip. Quoting by satellite measurement and customer photos lets you send prices the same day without driving out.

How do you get your first pressure washing customers?

Pressure washing sells on visible results, which makes the first jobs unusually good marketing. A clean driveway next to a gray one is a billboard the neighbors walk past daily.

• Work the street. After each job, leave door hangers on the houses that can see it, with a before-and-after photo and a neighbor price for this week.
• Realtors. Agents want listings to photograph well. A fast, reliable pre-listing wash is an easy referral relationship.
• Property managers and HOAs. Common areas, sidewalks, dumpster pads and building exteriors on a schedule. Have a certificate of insurance ready.
• Small commercial. Restaurants and storefronts with stained entries. Offer early-morning or night service.
• Your own photos online. Post every job to your Google Business Profile and website, before and after from the same angle.

Marketplaces exist for this trade too. Google's Local Services Ads bill you per valid lead, and Google's own systems decide which charged leads get credited back. On Thumbtack you are charged as soon as a customer whose job fits your preferences contacts you, and Thumbtack refunds the lead automatically if that customer answers no pro within 72 hours. Angi, per its SEC annual report covering 2025, collects its match fees even when the pro never does the requested work. Some owners use them to fill the first spring. Track every lead's cost against what it paid, and keep building the channels you own, because the next customer from your own Google profile costs nothing extra.

Which systems should a pressure washing company set up on day one?

Most pressure washing leads arrive in a burst when the weather turns warm, and the company that answers first and quotes fastest gets the job. Set these up before the burst:

• A business phone number with an automatic text to any caller you miss while your hands are on a wand. See business phone systems.
• Email on your own domain for quotes and invoices, set up with authentication so it lands in inboxes.
• A website with a page per service, your service area, a photo gallery and a quote form that asks for address and photos. See websites.
• A Google Business Profile with your service area, services and fresh photos every week in season.
• A CRM that turns the form into a quote, the approved quote into a scheduled job, and the job into an invoice with a card payment link. It should remind last year's house-wash customers when spring comes back. See our custom CRM.

The recurring opportunity in this trade hides in the database. A customer who had the house washed in May is a good bet for the same job next May, plus gutters in fall. Annual reminders and a simple maintenance plan turn one-time jobs into a route.

How seasonal is pressure washing across the US?

• Northern states and the upper Midwest: a compressed season roughly from spring thaw to late fall. Freezing temperatures make washing impractical and risky for equipment and surfaces. Owners there often add holiday lighting, gutter cleaning or snow work to fill winter.
• Mid-Atlantic and central states: a longer season with a spring rush, steady summer, and a fall push before the holidays.
• Southeast and Gulf Coast: humidity grows mildew and algae fast, so demand can run most of the year, and spring pollen brings its own wave of calls.
• Southwest and dry climates: less organic growth, more dust, hard water spotting and commercial concrete. Water restrictions during droughts can affect what you may wash and when; check local rules.

Plan cash around your region. In a short-season market, the money you make from April to October pays the truck in January. Book recurring commercial work and spring prepayments in winter, when people have time to read your email.
