Licensing
Do you need a license in Washington?
Dryer vent installation can fall under contractor or mechanical-code requirements in Washington, particularly when the work involves cutting into structures, routing through walls or roofs, or connecting to building systems. Requirements depend on scope and jurisdiction, and contractor registration through the Department of Labor & Industries may apply. Treat this as general guidance and verify current Washington state and local rules before performing paid 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.
