Do any of you do pressure washing for a living or for side work? I am interested in knowing rates. I have been doing some pressure washing and feel I am not charging enough as I usually do with every job I do. How do you charge for vinyl siding house, how do you charge for driveways, decks, how much for patios, etc.? Do you charge by the square foot, linear foot? Do you charge more for different ones? What is the safe psi for wood decks?
