Licensing
Do you need a license in Portland?
Licensing for dryer vent cleaning work is set at the state and local level in Maine, and Portland 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: Dryer vent cleaning is generally not licensed in Maine, and there is no state-issued credential for it, making it a low-barrier trade to enter. A local business license may apply if you operate your own service. Verify any municipal business licensing requirements in your service area before starting.
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.
