Insulation licensing in Missouri.
Missouri issues no state general or insulation contractor license, and the Division of Professional Registration regulates electrical contractors but no building trades. Local licensing exists but does not reach insulation: Kansas City licenses demolition, electrical, elevator, fire protection, gas appliance, mechanical, operating engineer, plumbing, residential building and sign contractors, while St. Louis requires a Construction Industry Contractor graduated business license with no trade competency examination. The genuine personnel credential for insulation is asbestos certification from Missouri DNR, which certifies abatement workers, supervisors, inspectors, management planners, project designers and air sampling professionals, each requiring a Missouri-accredited AHERA course plus the Missouri asbestos examination at 70 percent or better. Ask for DNR certification cards for named workers and supervisors. The same state rules apply in Kansas City, so candidates licensed there can work in St. Louis without re-qualifying. The St. Louis metro crosses a state line, so check the rules in the neighboring state too for crews that work on both sides.
Licensing authority: No state contractor license; licensing is municipal. Missouri Department of Natural Resources Air Pollution Control Program certifies asbestos occupations. Confirm current rules with the agency.
