there is no answer really, price a job with what ur happy with, most custy will say they have a window cleaners, but u will get the odd one who will ask a price then say i got one but ur cheaper or they are cheaper, i jad one the other week, knocked an estate and got a few of them, then started knocking bunglows and had a few of them say how much then that is ok, but can you started next month so i can get rid of the wc i have got, as he has just done them, some custy aint worth having they will always go with the cheaper price,
what i find a lot of it no thank you i have got a window cleaner, then when you are doing next door, they ask you to do theres, and make up so crap about there window cleaners leaving
