Alot of my yards are patchy and sandy! Which of course is terrible for the blades, deck, air filter, eyes, lungs ect. . Thing is, when doing estimates for them they think they shouldnt have to pay as much because there isnt much grass when actually they should pay more! Should I just charge more from now on and possibly loose some new acounts (due to high price) or try to explain why they are getting charged more than normal?
