Licensing

Do you need a license in Delaware?

Odor control and deodorization are technical services and are generally not separately licensed in Delaware. A local business license may apply depending on your municipality or county, and odor work tied to fire or water restoration may fall under those broader rules. A NISCR certificate is a professional credential showing your training, not a government license. Always verify any current local business requirements before offering services.

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. Licensing rules change and vary by city and county. Always confirm current requirements with your state licensing board before performing work.

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.
