Is mold remediation licensed in Wisconsin?
Wisconsin does not run a mold-specific licensing program. Only five US jurisdictions do (Texas, Florida, New York, Louisiana and the District of Columbia; Illinois has enacted a program that is not yet in force). In Wisconsin, the credentials to check are IICRC certification, general contractor licensing where applicable, and insurance.
What certifications do Wisconsin mold remediation firms actually hold?

Certification describes verified training rather than the services a firm chooses to advertise.
