Licensing
Do you need a license in Lexington?
Licensing for dryer vent installation work is set at the state and local level in Kentucky, and Lexington 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 can be more regulated than cleaning, because routing vents through walls, roofs, or mechanical systems may fall under contractor or mechanical code requirements in Kentucky. Because installation rules and permits vary by jurisdiction and can change, verify current Kentucky state and local code and licensing 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.
