How to start a pressure washing business, step by step

The short answer

To start a pressure washing business: 1) choose house washing, driveways and decks, or commercial work, 2) set up a structure and get a free EIN from the IRS, 3) check your state and city for licenses and ask where wash water may go, 4) get liability insurance, 5) buy a machine sized for the jobs you want, 6) price from how many square feet you clean an hour, and 7) win jobs with before-and-after photos.

Pressure washing is quick to learn and the results photograph well, which makes the first customers easier to win. The gear and the price per square foot are where to be careful.

Updated November 5, 2026. We make CoveDesk, a phone answering service that also looks after Google profiles for small businesses. Federal facts here come from the agency pages linked below. This isn’t legal or tax advice: check your state and city. How we check our facts

Step 1: Choose the work you’ll offer

Kinds of pressure washing work
WorkHow it’s doneWatch for
House washingSoft washing: low pressure and a cleaning solutionHigh pressure can damage siding and windows
Driveways and concreteA surface cleaner at high pressureQuick to learn, with easy before-and-afters
Decks and fencesLower pressure and wood careWood marks easily
RoofsSoft wash only, with ladders or roof accessHigher risk, so check your insurance covers it
Storefronts, lots and fleetsOften at night, under contractCommercial clients ask about wastewater

Step 2: Set up the business

  1. Settle the structure. The SBA (opens in a new tab) puts it simply: sole proprietorships don’t create a separate business entity, and LLCs protect you from personal liability in most instances. When a wand slips and etches a customer’s patio, that difference matters, so ask an accountant.
  2. Name it. Using a brand name rather than your own may mean registering a DBA, the SBA says (opens in a new tab), and it suggests searching the federal trademark database before you settle on one.
  3. Get an EIN, which the IRS says (opens in a new tab) you never have to pay a fee for.
  4. Ask about licenses at your city or county. The SBA notes requirements depend on your activities and where you work.
  5. Open a business account. The SBA lists (opens in a new tab) a merchant services account among the common ones, which lets you take card payments.

Step 3: Ask where the water can go

Wash water carries dirt, oil and whatever solution you used. Before you take jobs near storm drains, or any commercial lot, ask your city or county what applies to runoff, and ask the sewer authority if you’ll collect and dispose of water. Ask each customer before you use their outdoor tap.

Store chemicals in their original, labeled containers, and never mix them. That’s EPA’s advice (opens in a new tab) for hazardous household products, and it applies on a trailer too.

Step 4: Get liability insurance

Stripped paint, a cracked window or a dead flower bed are the everyday risks. The SBA describes (opens in a new tab) general liability as covering property damage and bodily injury claims. Ask your agent specifically about roof work and chemical damage to plants, and once you hire, the SBA says you’ll need workers’ compensation, unemployment and disability insurance. Your state runs most of these and sets the details.

Step 5: Buy the right gear

  • A gas pressure washer sized for your work. Flow, in gallons per minute, affects how fast you clean as much as pressure does
  • A surface cleaner for flat concrete
  • Hoses, a set of nozzles, and a soft wash setup for siding and roofs
  • Safety glasses, gloves, slip-resistant boots and hearing protection
  • A truck or trailer to carry it all, and a way to lock it

Start with the machine your first jobs need, and add soft wash gear when you take on houses and roofs.

Step 6: Price by the square foot

Time how many square feet you clean in an hour on your own rig, since that number drives everything. The pressure washing pricing calculator adds the drive, chemicals, overhead and profit. Its example is one person at $22 an hour washing 500 square feet an hour, with a 20 minute drive, $20 in chemicals and fuel, 25% overhead and 20% profit:

The calculator’s example numbers by area. Concrete goes faster than siding
AreaTime on sitePrice
500 sq ft1 hr$90
1,000 sq ft2 hr$130
2,000 sq ft4 hr$210
3,000 sq ft6 hr$290

Set a minimum charge for small jobs, quote larger ones on an estimate, and bill on the invoice template.

Step 7: Win your first jobs

  • Take before-and-after photos of every job, from the same spot. They’re your best advertising.
  • [Put your business on Google](/compare/how-to-add-your-business-to-google) and add those photos.
  • Offer the neighbors a price while you’re on their street.
  • Ask HOAs, property managers and real estate agents, who need clean exteriors before listings and inspections.

Pressure washing isn’t on Google’s Local Services Ads category list (opens in a new tab) we read, so don’t plan around those ads. Window cleaning services is, if you add windows.

After that: answer the phone

You can’t hear a phone over an engine. A business phone number with someone behind it, and a Google profile full of before-and-afters, are the next step for most new businesses. CoveDesk handles phone answering and Google profile management, on their own or together. Then add a business email and a website when you have time.

Common questions

Is a pressure washing business profitable?
It can be, if your price covers your time, drive, chemicals and overhead. The calculator’s example builds in a 20% profit share. Your speed on your own equipment decides most of it.
How much should I charge to pressure wash a 2,000 square foot house?
On the calculator’s example numbers, 2,000 square feet comes to $210, with about 4 hours on site. Siding washes slower than concrete, so enter your own speed.
How much does it cost to start a pressure washing business?
Mostly the machine, hoses, surface cleaner and insurance. The SBA suggests listing one-time and monthly costs separately before you buy.
Do you need a license to pressure wash?
Often a general business license from your city or county, and sometimes more where runoff is regulated. Check your state and city before your first job.
What PSI do I need for pressure washing?
It depends on the surface. Concrete takes high pressure, while siding and roofs are soft washed at low pressure. Flow, in gallons per minute, matters for speed as much as pressure.
Can pressure washers use Google Local Services Ads?
Pressure washing wasn’t on Google’s category list when we read it. Window cleaning was, if you offer it.
