Okay, so I got this random idea today to expand my landscape services a little and include pressure washing. There really arent many people at all that provide this service in my area. I know you guys have probably heard these questions before but I am gonna ask again anyways. I was just going to do siding, decks, patios, and drives. Nothing too major. I have a Karcher 2000 psi with an 8hp Honda engine and a few different tips to go with. It also has the tube to put detergents in too. So, I was wondering.....Do you charge a flat rate for this or hourly? What kind of cleaning stuff do I need to watch out for that is no good, etc? And the final question, do people care if you hook up to their water or do you have to bring your own?? Thanks for any help or anything extra anyone wants to add!!
