50% more than outside.
eg £12 outside; so would charge £18 inside would ask for ledges to be cleared, but don't mind pushing some bits side to side on ledge's
was thinking of advertising inside cleans but ony do on days the weather is too bad to work outside, i know some say custy's only want inside done on same day as outside.
But i think i could make it work; as a lot of window cleaners i talk to will not bother with inside work.
If custy is persistant with inside and out together, could flatly say no; only on bad weather days inside or will have to charge double inside.
But even double inside you could still be out of pocket
