I get calls from people now and then who have yet to mow their grass or worse they are "I'll call ya when I need ya" people. Now I have doubled or even tripled my price for the initial cleanup for these people but I have a question that I would like some input on. At what point is the grass so high that the price goes up? In my experience the grass is usually up to my knee and there is no question. But there has to be a height somewhere in between under control and out of control that everyone uses in their business practice. Would you say 10 inches? Or how about higher than the the top of your mowers deck? What do you use as a guide?
