re: Buying a smoker’s house

Duct cleaning, light wipe down of walls and ceilings with Simple Green solution, then two or three ozone generators and some time. Seriously, Kilz won't do a damned thing and neither will a few coats of even good latex paint over it, that smell will seep right back through. I've remediated a few rentals that had smokers and it's not something you can mask over.
