Licensing
Do you need a license in Lewiston?
Licensing for dryer vent installation work is set at the state and local level in Maine, and Lewiston 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 installation may fall under mechanical or building codes in Maine, and while there is no statewide general contractor license, installation tied to new construction, renovations, or HVAC equipment can trigger written-contract rules, local building permits, or Maine Fuel Board considerations for fuel-fired appliances. Always verify current state and municipal code and permit requirements before performing installation work.
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.
