I think this guy was just lazy. He probably has a POS blower and it was going to be extra passes to move that snow over to his side vs just throwing it in your yard. Most people dont know the affects of water close to the house rotting your sill plate and would assume this is one of those people. You have to remember that FHC people usually do all types of construction and home maintenance so are much better at understanding the affects of home neglect. I would just be friendly and go over there and ask him not to do it anymore. Bet it will clear it right up.
