Licensing
Do you need a license in Wilmington?
Licensing for odor control work is set at the state and local level in Delaware, and Wilmington 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 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.
