re: Anyone do pressure washing as a side business?

It's what I do for a living. What do you want to know? There was a time when it was my "side business" like you're describing and then one thing lead to another and I went full time. I originally started right out of high school and did it all through college. Hung it up when I graduated, did the corporate thing and drifted back in.

It has become an extremely saturated industry. There's yard guys/handyman, the Craigslist clowns, the painters and then there's full blown services. All are very different.

There's a lot more to pressure washing than just going out there and blasting away.
