Its no secret that you can talk your customers into keeping you on even if you use a system that they would rather you didnt! As window cleaners we have the rare position in business of having a personal relationship with our customers and that is why we retain them. The truth is they would rather not have their house soaked with water, their plants damaged by your hoses and their windows covered in tiny spots but they don't want to hurt your feelings!!!! So they hand over there cash and stay loyal and thats one of the many reasons ats such a unique business! What you reckon?
