So get rid of window cleaner,
If custy doesn't have ladder buy one and cleaning equipment got to come to arond £100
save £20 then and if your not competant on ladders risk serious injury or death.
great tip or spend £1500 + on wfp small setup to do windows.
I think people like like clean windows will pay for window cleaner.
The only real alternative is leave em.
I know you can wash your own car or mow your own lawn.
But do your own windows, another story.
having said that, i know it's not essential that you have your own windows cleaned.
all you can do is sell your service to those that want it and not worry about those that don't
sorry to hear you lost 11 custy's mate probably like everyone your 3-4 weeks behind, it'l take you til spring to catch up hope you claw some back then or canvass then for more.
