Give em the rain guarantee talk,ive never understood the mentality of doing them only when its dry,its always gonna rain again.
We all need to start working in the light to medium rain [wfp] to get rid of this stupid idea that you cant clean windows in the rain,if they protest to me i explain why it still works,most are ok with it ,if theyre not i just move on to the next one.You have to get out and earn a living.
They all got quoted a once a month price,not a when it suits them price.
I know its easier to say all this when you got enough custies [i have] but to be honest in 6 years i only had one cancel and that was because i did them just before it rained,what a waster better off without some of them.
