Can anyone recommend any decent canvassing companies please ?
Better doing it yourself if you can, you will get the prices U want, as i reckon a canvasser will just want to "get the job in" for the sale/ %, and overlook things like: Bad access, Dangerous extension roofs, Building work, Locked gates/phone call, Parking, Dog mess etc. This will affect the price of the job, and whether or not, you would take it on.
