Smoke coming from neighbor
Hello. We recently purchased a twin house in NJ. The neighbor's side of the twin is split into two apartments. One apartment on the first floor and another apartment on the second floor. Our neighbor on the second floor smokes and we smell his cigar/cigarette smoke in our second floor hallway and in our one year old's bed room. We tried using spray foam on some of the holes in the dry wall that we saw. There is a brick firewall behind the drywall. I assume the firewall is complete wihtout any gaps but I have no way of really knowing wthout removing all the drywall in the hallway and hallway ceiling. Anyone have any thoughts or suggestions as to how we cna handle this? We asked our neighbor to crack a window but he refused to comply. HELP!
