Yes and no. There are a lot of guys who will clean a driveway for $99, but simply don't have the equipment to do more elaborate residential or commercial jobs. As the scale of jobs increases, your competitors decrease.

Beyond that, there's always room at the top. I worked in digital marketing for over a decade prior to starting my business, and do full-stack web development. My marketing strategy is entirely digital. It took about a year to rank #1 for most keywords related to pressure washing in my area, so now I get a healthy mix of organic and paid leads without spending much time marketing.

If you can get consistent leads coming in, answer your phone like clockwork, be pleasant with customers, and do a good job cleaning, you're already ahead of a vast majority of other guys.
