Licensing
Do you need a license in Houston?
Licensing for dryer vent cleaning work is set at the state and local level in Texas, and Houston 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 a separately licensed trade in Texas and has a low barrier to entry, though a local business license is commonly required to operate legally. If work extends into modifying or installing vent systems, building or mechanical codes may apply. Always verify current municipal and state requirements for your services. A NISCR certificate is a professional credential, not a government license.
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.
