I don't do my own, haven't got time, too busy trying to make money. So I get the local lads to do them each month, they're ridiculously cheap, 5 windows and the sills for £2.50, . I told him he's working for nowt but he says he's too scared to increase his prices for fear of losing work. I started giving him £3 now , even if it was a fiver I'd still pay it cos it saves me doing it, although I do clean my conservatory a few times a year!!
