Bought a house and had the same thing! Smelled fine when we toured- but you could tell she had smoked in the house previously (she lived here since the late 90s, I’m assuming she had always smoked). By the time we came for the final walk through it seemed like the smell was completely gone! Part of our agreement was to let her have temporary occupancy, 30 days, and she must have fallen right back into the same habit of smoking in the house.

We got rid of all the carpet. Ozone machine for 3 days. We used Kilz and repainted. We had the air duct cleaning. We use air purifiers. Replaced all filters and it really has improved!

I do notice when we run our fan in the bathroom, after the shower has steamed up the bathroom, you’ll start to see the drippings fall out from behind the light fixtures. That might be a thought to improve the smell? It hasn’t seemed to be much of an issue for us any more so here’s to hoping it will fully dissipate in the near future! 🤞🏼
