I started a remodel about a month ago for an investor. Among the mostly asthetic oriented work I am doing, I have to eliminate a strong pet smell. I have done this several times before by simply removing the carpet and painting. Well, this one will not go away. There is small bathroom that they must have locked the animal up in that seems to be the origin of the smell. I have used peroxide on the walls and floors to no avail. I have crawled into the crawlspace and spread lime all over it. I have torn up and replaced some of the more obviosly stained subfloor. I have torn out drywall and replaced with new drywall. It is still there. Is there anything out there that I can do for this? I know I can tear everything out and replace it, but, that is not economically possible.
