Licensing
Do you need a license in Missouri?
Dryer vent installation can be more regulated than cleaning: in Missouri, venting that ties into building or mechanical systems may fall under local contractor or mechanical-code rules, even though no statewide contractor license exists. Requirements vary by city and county, so verify current local and state rules before installing. A NISCR certificate is a professional credential, not a contractor or mechanical license.
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.
