$275 is a fair price for that house(in my area and my opinion) without ext gutters or wax.How many of these premium price house washes are repeat annual customers??Theres something to be said about customer retention in the continuing success of of a company charging rates like that. I can preach professionalism to the customer all day in my polo shirt,brochures,fancy rig,etc etc.95% of the time it's not got going to matter to the person who lives in a house like the one pictured, especially since they'll be pissed to learn what their neighbors paid.I know I'm close to maxing out my market by evaluating my numbers and by lake side mansion owners telling me that they are shocked with my quote.Just my limited 2 years of experience take on it.Have you ever seen a trailer park,Ken?jk
