hi today i've been accused that i charge more than other ''professional'' trades and even more than a doctor.after i finished cleaning his house windows he called me and showed me the frames and said they are still not clean enough,black runs one some corners and sills which they don't come off with the brush.i said they need more than just a normal maintenance clean.more like a restoration,a service i don't offer.he asked if i can do it for him and said i can try but don't know how long it will take and how much to charge so i said i'll charge £20/h as he's and old and reliable customer.he almost had an heart attack and said he doesn't give that much to one of his bricklayers(i believe he owns a building company).after a long chat explaining that it's not that easy to be a window cleaner,that we do have expenses and don't work in heavy weather conditions i managed to '' calm'' him down.although he said he can't afford to pay me that much an hour and said he'll look for some one else to do it(maybe his bricklayer).i'm quite happy he said no as the work that is involved in cleaning every inch of the frame with a sponge/cloth and upvc cleaner it's not worth £20/h
