This is exactly why I am so opposed to the sort of posts that invite people to say how much they can earn from window cleaning.
There was one a while ago that was constructed like a survey. Some of the posts contained more than a whiff of Bulls**t and the trouble is people believe them.
I know I could, indeed should, be charging more than I do. My wife tells me so all the time. However, prices are going to be more competitive in the future because new window cleaners are starting up all the time. They are being displaced from other trades and professions by a massive influx of cheap labour from Eastern Europe. Its only just starting to happen but its going to get worse.
I was talking to a bloke this week who for the past few years has had a thriving business doing wood flooring. His work has all but disappeared because every way he turns he is being undercut by Polish "gangmasters" who don't do the work themselves but just act as a middle man employing thier own people.
They have got it all very well sewn up, not just flooring, they do everything, painting, decorating gardening,general building etc while their wives and girlfriends do cleaning jobs and work in nursing homes and shops.
The effect on the local trades people round here hasn't really started to become evident yet but there are a lot of men out there who are struggling in silence. However, they can't stay silent for ever. They have bills to pay and most of them own a set of ladders. You can work the rest out for yourself.
