I work with my missis and she's very good. She's only five foot one, so permenantly carries round a set of six foot A-Frames and we have our own little systems going which make for quicker cleaning.
I've been window cleaning for about a year and around here, I earn around £13 to £18 quid an hour (on days I don't have a trillion drive-betweens). It is quite a prosperous area mind. With Helen it increases to £20 to £25 quid an hour.
So I can't complain apart from... she always wants the bloody toilet, although she will pee behind sheds if she's sure no-one is watching.
Oh, and there was the time we were arguing and she dropped her belt kit, threw her A-Frames at me and told me to "stick my job up my arse"!
We've found that if she works three days a week - we get on fine. Any more than that, we get on each others nipple ends.
