First off, i did try to do a search, but it kept telling me that there was an error, so I read through as many posts as I could; however I was left wanting. I am interested in adding pressure washing to my business offerings, but I have some basic and not so basic questions. I have garnered that for a professional set-up, volume is more desirable then pressure. It seems that CAT brand is also a good pump manufacturer. What other benefits do higher volume pumps have? Is it that they are less likely to strip paint off, and/or damage things? What other brands of pumps are acceptable? or is this like a ford v. Chevy thing? When adding chemicals to the mix (no pun intended) what kind of safety issues does one have to look out for? Are most cleaning agents simply bleach or a detergent? What about add-on's? I saw something about a surface cleaner, what is that? Why is insurance so much more expensive then mowing, apparently? If that is accurate, what would be an acceptable first year premium. (PM me if your so inclined) Also, what are the marketing challenges with this type of business versus a landscaping operation. Thanks in advance!
