Licensing
Do you need a license in Nashua?
Licensing for odor control work is set at the state and local level in New Hampshire, and Nashua 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: Odor control and deodorization are generally not separately licensed in New Hampshire. When performed as part of a larger fire, water, or mold restoration project, the broader job may carry contractor or local registration requirements, and a municipal business license may apply to your operation. Always verify current state and local rules for your specific services. A NISCR certificate reflects professional training and is not a government-issued 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.
