Smoke and nicotine stains

[Chris McDaniel]

Hi all, Okay, so I just took position of a property and the previous owners smoked inside for years. Everything is yellow. I’ve gutted the house and painted two coats of kilz, the house still smells really bad. It’s been airing out for two weeks and I can’t seem to get the smell out. Any thoughts, suggestions or ideas? A friend recommended an ozone machine but I don’t know anything about them. There is literally nothing left in the house that can be taken out, except all the Sheetrock. Anyone have any thoughts?
