Since power washing uses heated water, it requires more expensive equipment, meaning you'll pay more for power washing. However, you get what you pay for in this case—especially if you have tough dirt and stains you want to quickly remove from concrete surfaces or other durable materials.

This could be a lucrative side gig or a full-time operation. Consider that the average pressure washing costs between $192 and $401 per job. If you did two jobs a day at $250 each, you'd make $130,000 a year working 260 days per year. That's good money and a lot of time off to enjoy it.

Commercial and Heavy-Duty Applications Pressure washers with a PSI of 2500 to 4000 are considered more suitable for these heavy-duty cleaning jobs, offering the power needed to tackle stubborn dirt and grime.

Promote your services to businesses and homeowners in your community by delivering pressure washing flyers or door hangers. Or, create your own tearaway flyers to place on community bulletin boards in local libraries, grocery stores, gyms, or community centers—just make sure to ask for permission first.
