I first cleaned windows in 1958 with mop and scrim. I remember doing a hotel in Llandudno watching princess Margaret getting married through the window. We thought squeegies were OK for shop fronts but no good on domestics because most had small panes. WFP has been the game changer, it allows guys who would get dizzy standing on a chair to become window cleaners. I'm 73 in September and often get asked when I'm retiring. There is a guy the same age next door, he goes to the gym 4 days a week.
Now why would you pay to get your exercse when you can get others to pay you while getting it?
I only use ladders to access balconies, and to be honest hate taking them off the trailer. Every thing gets done WFP and I have just bought new SLX 25 AND 18FT poles [Tip, fasten a bit of ordinary garden hose to the bottom section, you can then fold the Gardener pole hose, stick the fold into the piece of garden hose, and you can then stop the flow no matter how high your cleaning]. I only do 3 days a week now days, but I also have a small commercial fishing boat to earn more if I need it. I also have a 5 year old daughter and 37 tear old Mrs to keep me on my toes.
I'm just another old bloke who cleans windows, what they don't know is I am still knocking out £30 an hour. Window cleaning really is a great occupation, no collecting any more, but far too many online payments that you can't hide. Another big game changer.
