lee if your getting quite a lot of customers saying "keep the change" it indicates that you could be charging more.

chris what do you mean "average" house?3 bed semi on estates with say 7 or 8 windows?if your cleaning the frames and doors,ledges etc then you will only clean 4 an hour trad IF they are all very compact next door to each other. so on your price of £4-£5 per house youll be making £16-£20 an hour but less than that if you have to drive between jobs as youll probably only clean 3 houses at a push.are you happy with this pricing?
i never ever let a customer choose what method of cleaning to use whether wfp or trad.could you imagine a joiner coming round to do some work and asking you what tools you want him to use?

i do trad some ground floor windows on some properties where its awkward to get the hose and pole and where its just as quick to use the mop and squeegee but i never ever use ladders on upper windows if i can reach them with the pole.
i find lots of customers are very happy with the pole system and even comment on how good the finish is plus all them awkward windows,conny roofs,fascias,soffits and solar panels can be cleaned to a good standard if they so wish.
as for inspiration stories i was once a hopeless penniless alcoholic who slept in my car or on peoples sofas many years ago.im doing alright for myself these days after years of struggling to get out of debt etc,etc.

best wishes to you all
