Licensing
Do you need a license in Columbia?
Licensing for dryer vent installation work is set at the state and local level in South Carolina, and Columbia 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: in South Carolina, new vent runs may fall under mechanical or building codes and, depending on scope, contractor or mechanical licensing, particularly within new construction or remodels. A local business license generally applies. A NISCR certificate is a professional credential, not a government license, so verify current South Carolina building/mechanical code and licensing requirements before installing vents.
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.
