Mold licensing in Wisconsin

Wisconsin does not have a state license or certification requirement for mold inspection, testing or removal. The Wisconsin Department of Health Services says neither the state nor the federal government certifies mold consultants or contractors, so be wary of anyone advertising as state certified. Ask any mold company what training it has, such as voluntary IICRC certification, and get a written scope of work and proof of insurance. Check Wisconsin Department of Health Services (DHS)'s site for current information.

Radon licensing in Wisconsin

Wisconsin does not have a state license or certification requirement for radon testing or mitigation. The Wisconsin Department of Health Services says contractors are not required to hold a state license or national certification, but recommends choosing one with NRPP or NRSB certification. Many radon companies hold voluntary national credentials from NRPP or NRSB, so ask for proof of certification, and ask about any contractor licenses that apply to the work, such as electrical work. Check DHS's site for current information.
