About this listing
It means we located this company’s license in the source named in the table above and read it on the date shown. It is not an endorsement, an inspection of the company’s work, or a guarantee of anything.
The company name, phone number, city, and license details come from the Illinois Emergency Management Agency and Office of Homeland Security’s published license records, as published on November 1, 2026. We have not added anything the state record does not say.
We list Illinois companies that hold a current mold assessment or mold remediation license from the Illinois Emergency Management Agency and Office of Homeland Security. A licensed company that is missing appears after our next update from the state’s records. Nobody pays to be listed.
