All my work from day 1, 14yrs ago, were set on monthly cleans. No 2weekly or 8wkly. Didnt give any options and when asked I simply tell them that they can, but it will be nearly double charge for the 2mnths of grime on windows. Funny no one went 8wkly. Now on wfp, have I gone 8wkly....must be joking. To maintain this fabulous clean windows for longer, they need regular maintaining with this modern technology. Therefore my schedhle is simple, each week has a round of work for full wk and then move onto next. So when get messers I can drop them (it peeves me off cause of the principle, just say I have no money n dont want em doing,,,,) as im always taking on new as you guys experience the same....so I dont take note.
