My tenant who spent the last 12 years occupying my rental finally moved out along with her 2 small dogs. Well I knew the floor was going to be bad after the horrible urine smell that was left in the unit. Removing the old carpet and padding was pretty horrible due to the smell. Once we got the padding up I saw how bad the wood was and tried cleaning it with bleach and a mop to get the smell out. I'm debating if I should just remove the subfloor and replace it with new wood. It's something I really don't want to do but will if I have to. I do have one small area that will have to be cut out and replaced. Yesterday I put down some Natures Miracle Urine Destroyer and waiting for it to dry to see if it helps with the smell. If it does I can apply some Zinsser BIN to seal it and install new flooring. What do you guys recommend? The floor looks pretty bad with stains. I've never seen one this bad but I don't have much experience with rental properties. Snapped a quick pic of the floor. This was after about 48 hours of applying lots of bleach and a mop with the windows open. I know have a fan in there helping to dry the floor.
