Is mold remediation licensed in Montana?
Montana 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 Montana, the credentials to check are IICRC certification, general contractor licensing where applicable, and insurance.
