if that's the case . I just wonder why most sole window cleaners always canvass now and then lol
i dont generally.my round is self generating but if i get a new job in a nice posh area i will leaflet/canvass houses either side of new job!
also customers drop out for other reasons.moving and death being the main ones followed by losing jobs/cant afford a window cleaner.
all our rounds are like shifting sand.constantly evolving and changing over time no matter how well established we are.
