The honest answer is under $1,500 if you buy your first pressure washer used and start with driveways, not houses. A brand-new setup runs closer to $2,500, and the $12,000 trailer rigs you see online are a year-two purchase, not a starting cost.
Here's where the money actually goes in month one:
| What you buy |
Realistic cost |
| Used 4 GPM gas pressure washer |
$600 to $900 |
| Surface cleaner attachment |
$100 to $200 |
| Hoses, wand, nozzles, safety gear |
$150 to $250 |
| Chemicals (sodium hypochlorite + surfactant) |
$50 to $100 |
| Flyers and a basic phone listing |
$50 to $100 |
| Total to start |
$950 to $1,550 |
Most "how to start a pressure washing business" videos are made by guys trying to sell you a $12,000 trailer rig on day one. You don't need it. Year one is a used 4 GPM gas machine, a surface cleaner, and three flyers in your neighborhood.
The surface cleaner attachment ($100 to $200) is the one piece of gear most new washers skip. It's the round disc you push along a driveway instead of using a wand. It turns a 90-minute driveway job into a 20-minute one. Without it, your labor cost per job is so high the margin barely works. With it, a driveway pays for itself in the first pass.
Chemicals are simpler than the YouTube guys make them look. Sodium hypochlorite (pool shock) plus a surfactant covers about 95% of residential jobs — driveway oxidation, house siding, sidewalks. The branded "soft wash" mixes are the same thing at 3x the price. Don't buy them until you're running a high-volume operation.
Test the spigot before you quote. Some houses have weak water pressure that can't keep up with a 4 GPM machine. If you quote a job and can't run at full capacity, you either finish slowly or walk off — neither is good. Check flow rate before you give a number.
The rest — exact machine specs to look for on Craigslist, chemical ratios by job type, pricing tables by city, and the four job types to walk away from — is in the full plan:
