Pricing is always a touchy subject. There are some on these boards that feel that they are not making money if they are not making $100.00 a man hour. Others are satisifed to make $50.00 a man hour. So it all depends. I will let you in on a few secrets.
1. Homeowners are not willing to pay more than around $50.00 an hour, in general. Everyonce in a while they will pay more, especially if it is something that htye feel that they have to have, such as a car repair, Plumbing repair, etc. But for power washing it is not considered in the same realm of importance. So they are not willing to pay the price.
2. You are financially better off working 35 hours a week at $50.00 an hour than you are working 15 hours a week at $100.00 an hour. The more hours that you work also helps you build a larger, more stable customer base for the slow times. However, you can stay home and go broke, so din't underprice yourself.
3. There are a few guys in small markets that can succeed by doing everything, Decks, Hoods, Fleets, Flatwork, etc. But for themost part the large contractors specialize in one area. You seem to specialize or target the residential markets. That is okay, if your services are used in your area. I would advise against going out of your realm and trying something else, unless you are totally committed to it.
4. Equipment is important. If you use Junk you will have more breakdowns, and the customer will be more likely to be disappointed in your work. Quality equipment to a lot of people means a quality job. Your equipment can be old, but it must have a good appearance.
These are just a few thoughts. Of course, there will probably be people that disagree with me, but, that is the way I think.
