Help! Pet odor in the basement - can't move in to my new home.
I purchased a home in which the seller's kept two large dogs and 2 cats, confined to an unfinished room in the basement. The odor was overwhelming! I have bleached the floor in this room, used a commercial fan, and cried. The remainder of the basement (1800 sf), is covered with an indoor/outdoor carpet. I have shampooed this carpet, as well. This has resulted in decreasing the odor, but it is still there. In fact, as soon as I turn the fan off, it gets strong again. This is not a urine smell. Rather, it is a "wet dog" smell.
I would appreciate any advice you may provide.
