Im new to this site, Id appreciate any suggestions I can get here. My ex husband and I started building a home 10 years ago, he got as far as "liveable" that was good enough for him. Long story short, my hallway never had any flooring other than the plywood subfloor. Since I keep my dogs in the hall/kitchen when Im at work in the winter, of course, now the hall has a pet urine odor. Im going to lay some sort of flooring on it soon, but I dont want to lay it over this. Is there a way to get the odor out of the subfloor? Replacing it isnt an option for me, I have neither the skill to do it myself or the ability to pay someone to do it.
