The main benefit of starting a pressure washing business is that it tends to have relatively low costs upfront and a fairly high profit margin. According to Grand View Research, the pressure washing industry is expected to grow 3.4% between 2018 and 2025.  Plus, you don’t need an advanced degree or training to provide pressure washing services. In fact, you might be able to learn everything you need to know by watching YouTube videos. If you’re looking to run your own company and be your own boss, pressure washing could be a good business to achieve those goals.
