A practical guide to launching a pressure washing business in the US: services, equipment, licensing and insurance, water runoff rules, pricing, safety and growing a crew.
Pressure washing covers a wide range of work, and each needs different skills and equipment:
| Service | Typical customers | Notes |
|---|---|---|
| House washing (soft washing) | Homeowners | Low pressure with cleaning solutions to protect siding |
| Driveways, patios and sidewalks | Homeowners, property managers | High pressure and surface cleaners |
| Decks and fences | Homeowners | Wood is easy to damage; often paired with sealing |
| Roof cleaning | Homeowners, HOAs | Specialist technique and fall protection needed |
| Commercial flatwork and storefronts | Retail, restaurants, offices | Often recurring contracts, sometimes at night |
| Fleet and equipment washing | Trucking, construction | Recurring work; wastewater rules are important |
Many new businesses start with residential flatwork and house washing, then add commercial contracts once they have reliable crews and equipment.
Buy for the work you will actually do first. Second-hand equipment can work, but check engines and pumps carefully.
Register your business with your state, get an EIN from the IRS if you will hire and check local business license requirements, which vary by city and county. Some states or localities require a contractor license for certain work, such as painting or sealing after cleaning, or for jobs above a dollar value. Ask your local licensing office before quoting.
Insurance is essential: general liability for property damage, commercial auto for vehicles and trailers, equipment coverage and, once you have employees, workers’ compensation, which most states require. Commercial clients will often ask for a certificate of insurance before you start. See our workers’ compensation guide.
This is the area new businesses most often overlook. Wash water can carry dirt, oil, grease, detergents and chemicals. Under the federal Clean Water Act and state and local stormwater rules, many places restrict letting this water flow into storm drains, which often lead directly to streams and lakes. Requirements differ: some areas allow certain residential runoff to landscaped ground, while commercial jobs, such as restaurant dumpster pads or fleet washing, may require collecting the water and disposing of it properly.
Contact your city or county stormwater program or the local wastewater authority to learn the rules before you start, and build the cost of recovery equipment and disposal into your prices where needed.
Pressure washing looks simple but causes real injuries. High-pressure water can cut skin and inject water or chemicals under it, which needs urgent medical care. Other risks include falls from ladders and roofs, chemical burns and eye injuries, electrical hazards near outlets and lights, slips on wet surfaces, engine exhaust in enclosed areas and noise. Train every worker before they handle equipment, use the right nozzles and protective equipment, never point a wand at people and keep chemical safety data sheets available. See our toolbox talks guide for short safety briefings.
Many pressure washing businesses price by square foot for flatwork, by house size for house washing and by hour or contract for commercial work. Whatever unit you use, base it on your real costs: labor including payroll taxes and insurance, travel time, chemicals, fuel, equipment wear, overhead and profit. Time a few jobs carefully at the start to learn how long common jobs take, and adjust your rates from real data. Our pricing guide for trade jobs shows the method, and our profit margin calculator helps check margins.
Once you are turning away work, it is time to hire. Make sure helpers are classified correctly; workers you train, equip and direct are usually employees, not contractors. Pay non-exempt employees for all hours worked, including travel between job sites during the day, and overtime over 40 hours a week. See contractor vs. employee and travel time pay.
With more than one crew, you need simple systems: a shared schedule, clock-in at each job, job checklists and a way to track hours per job so you know which jobs are profitable. See field employee time tracking.
A new owner starts in early spring with one trailer rig, offering driveway, patio and house washing in two nearby neighborhoods. They time every job for the first month and adjust prices. By summer they sign two restaurant contracts for monthly dumpster pad cleaning, after confirming with the city that wash water must be collected, and buy recovery equipment. They hire one helper as an employee, train them on safety for a week and use a mobile app for clock-ins and job photos.
EZTime helps small field crews run smoothly: employees clock in at each job from the mobile app with optional GPS location, schedules are shared with the crew, time can be assigned to jobs with job and client tracking and job checklists can be completed with tasks. Approved hours are exported for payroll. See EZTime for cleaning services.
| Service | Typical equipment |
|---|---|
| House washing | Soft-wash system, ladders or extension wands, surfactants |
| Driveways and patios | Surface cleaner, hot or cold water unit |
| Decks and fences | Lower-pressure settings, wood-safe cleaners, brushes |
| Commercial and fleet | Higher-flow units, water reclaim equipment where required, a trailer setup |
Buy for the services you will actually sell in the first season. Rent or borrow specialty gear until demand is proven. See how to write a business plan.
Book jobs into routes by neighborhood to cut drive time, send reminders the day before and confirm water access with customers. Track the time each job takes by surface type, so your estimates improve every week. When you hire help, record hours accurately from the first day and pay helpers as employees unless they are genuinely independent. See independent contractor vs. employee and job scheduling.
Tick each item you have done.
0 of 6. You are at the start. Focus on services, registration and insurance first.
You will usually need a business registration and a local business license. Some places require additional licenses for certain work. Check with your city or county.
Often not, especially for commercial work. Rules vary, so check with your local stormwater or wastewater authority before starting.
Commonly general liability, commercial auto and equipment coverage, plus workers’ compensation once you hire employees.
Often by square foot for flatwork, by house size for house washing and by hour or contract for commercial work, based on real costs.
It can be. High-pressure injection injuries, falls, chemical burns and slips are real risks. Train workers and use protective equipment.
Workers you train, equip and direct are usually employees. Check the tests before classifying anyone as a contractor.
EZTime’s mobile app stamps each clock-in with GPS, and approved clock-in locations flag punches made somewhere else.
