I started window cleaning for a company at the age of 16 35 years ago new window cleaners was called tumblers and was on about £30 a week and it took about 18 months before you was getting the same money as the window cleaners.You had to learn how to move and work on 30 foot ladders.You could tell if someone was a window cleaner just by the way they washed out there tools.If you come down to london and wanted to be a window cleaner in the city you would have to work in a cradle 30 floors up or do abseiling over the side of a building.I could go on and on. Iv have got wfp iv have got gardiner poles and use them when needed.
water fed polers clean houses.window cleaners can clean eveything. anyway good luck but if i was you i would go and work for someone for a year or so and be a real window cleaner.
