Licensing
Do you need a license in Massachusetts?
Odor control and deodorization are generally not separately licensed in Massachusetts. If deodorization is performed as part of a larger restoration or reconstruction project, the construction portion may require HIC or CSL credentials. Use of certain chemicals or ozone equipment can carry safety and disclosure considerations. Verify current requirements with the Massachusetts Division of Occupational Licensure and your municipality. A NISCR certificate is a professional credential, not a government 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.

Curriculum
What you’ll learn
- Locate hidden odor sources — subfloor, HVAC, wall cavities, and porous materials — instead of treating the air alone.
- Match the deodorization method to the odor type, distinguishing smoke, pet, decomposition, mold, and chemical odors.
- Operate ozone generators safely, including unoccupied-space protocols, dwell times, and post-treatment clearance.
- Run hydroxyl generators to deodorize occupied spaces where ozone would be unsafe.
- Apply thermal and ULV fogging to drive deodorizing agents into the same pathways the odor traveled.
- Seal residual odors in framing and substrates with the correct primers and encapsulants after source removal.
