we work 4 weekly ( some 8 weekly ) , so the customer knows when we are coming !
i phone / text very few , my choice .
my feedback over the years is that customers, once they have taken us on , do not have much more interest in the details of how we work. we make a reasonable effort to get to the back when req , however some do become front only ( and charged accordingly ) .
i appreciate if you are just starting out you want to clean every window for whole house price , but it will stop you driving round in circles and customers having you at thier beck and call .
