Licensing
Do you need a license in Texas?
Texas does not require a statewide license specifically for garage door repair, but installation and structural or electrical work can fall under contractor, electrical, or local building-permit requirements, particularly for new installs and opener wiring. Requirements vary by municipality. Always verify current local building-code and licensing rules before performing installation work. 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.
