In the case where dog urine or cat urine has soaked into or through the carpet padding, it’s tougher to eliminate the pet urine odor completely. The issue is that the odors are lurking underneath the surface, in the carpet padding and/or the floorboards. In extreme cases as we’ve seen, you may need to replace your carpet, carpet padding and/or some floorboards. The trick is to catch the pet urine ASAP and treat it before it soaks through. Sometimes it’s too late, however. We’ll do our best to eliminate or neutralize pet odor, but there are extreme cases where 100% neutralization of pet urine odor is not feasible.
