Licensing
Do you need a license in New Hampshire?
Unlike simple vent cleaning, dryer vent installation in New Hampshire can fall under contractor or mechanical codes, particularly when venting passes through walls, roofs, or interacts with gas appliances. Permits and a local business registration may also apply. You should verify current New Hampshire building, mechanical, and municipal requirements before performing installation work. A NISCR certificate documents professional training and does not replace any required contractor or mechanical 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.
