I have a tenant who's complained of a mildew smell in her apartment. She says that the smell is coming from the carpet, and that the odor becomes very strong whenever it rains. She also says that the mildew smell is strong in one of the closets. I checked her apartment, and there is a mildew smell in the closet she identified, however, I don't smell anything coming from the carpet. Also, I just replaced the carpet in her apartment less than 1 year ago.
Is it possible that the carpet could be causing this smell? Could it be the padding under the carpet? Could the padding underneath the carpet be causing this smell(I didn't replace it when I replaced the carpet last year)? If necessary I'll replace it, but I'd hate to spend money replacing the carpet or padding is that's not the cause. Is there anyway to pinpoint the source? Or are there any services out there that I could contact? I want to resolve this issue for my tenant, but I don't want to just throw money at the problem. Any help would be greatly appreciated.
