if it says no canvassing then don't knock, card or leaflet the property and you will still pick the odd job up

Sorry but I ignore all stickers of this kind. In fact, when I have asked whether they minded me knocking because of the sign they have mostly said that they don't include window cleaning under their definition of 'cold calling'.
Round here the council went on a binge of delivering the stickers to every house for free so they are on virtually every house window or door - if I did take notice I wouldn't be able to canvass 85% of the houses.
If they do answer the door and mention the sign just say 'sorry, I only saw the sign after I had knocked and I thought it would be rude to then walk away before you answered the door'.
Crack on is the best way - most are relieved you're not selling Gas, Electric or PPI for a change.
Cheers, Tom
