I also win bids with higher prices. I have a cold water machine 4gpm 3000 psi and get calls to wash anything from a ranch house to 3 story commercial buildings and even a fleet of 24 RV's. I use cold water more chems than the hot water guys and charge more and still get the work. Quality and salesmanship will get you far. Hot water is in the works for this year. If your sales technique, appearance and quality is all good then people will choose your company over another inspite of price unless you are way off. One point, I am V.P. of a masonry company and we put in a bid on a town house foundation and footers. near 60,000.00, we were 10,000.00 higher than than the next guy on the list, we were the high bid by a long shot. After reviewing the bids, the contractors asked why we were so high we explained all the aspects of the bid. Turns out the lower guys had missed alotof small details that added up in the end. Our reputation and experience along with extreme attention to detail won this bid. I run my pressure washing business the same way. I don't leave a job until its done as if it were my own and I charge accordingly. I agree with the above post I usually charge 55.00 - 60.00 dollars an hr + business costs (all costs in one year averaged into a daily figure per working day).
