Licensing
Do you need a license in Saint Louis?
Licensing for mold remediation work is set at the state and local level in Missouri, and Saint Louis may add its own business-license or registration requirements on top. Always confirm current city and county rules before bidding work. For the statewide picture: Mold remediation is one of the few trades where licensing genuinely matters: several states (including Florida, Texas, and Louisiana) require a state mold license, and rules differ sharply by location. Missouri does not currently mandate a statewide mold remediation license, but this can change and local requirements may apply, so you must verify current Missouri and municipal regulations before working. A NISCR certificate is a professional credential and is never a substitute for any government license your jurisdiction requires.
A NISCR Certificate of Completion confirms completion of NISCR training and examination. It is a professional credential, not a government license. Where local law requires a license to perform a service, the technician is responsible for obtaining it.
