So I'm haus shopping. Found a place I dig. Current owner is a smoker, I am not
The place has all hardwood - no carpets. A bit of furniture remains - a sofa, bed, and minimal fabric blinds. The place has all cedar-planked ceilings. I've been there twice and the first time, the odor wasn't too bad, the 2nd time, worse (think the owner must have been there shortly before we were). It's not crazy-strong - not like nicotine stains on the wall or anything, but noticeable.
I've looked a bit into odor removal, and it seems that home restoration companies do this (mainly for house fire recovery), using a combination of wall scrubbing, duct cleaning, odor-sealing primer paint, and ozone gas neutralization.
Anyone have experience with any of this? I am not sure I can make an offer without somehow being guaranteed that the odor can be removed.
