Louisiana Plumbers

Louisiana might be a state that is known more for Bourbon Street and Mardi Gras than their plumbing requirements, but that doesn't mean that there isn't a set of standards that is in place. All licenses are governed by the state's licensure board, so to become a licensed plumber in Louisiana, you must be able to provide the following information:

  • To become a journeyman plumber, you must provide 8,000 work hours of apprenticeship experience that is verifiable in some way. If you do not have 8,000 total training hours, if you can provide five years of on the job training experience, this can substitute for the total hours. Plumbers who are moving into the state can show a valid plumbing license to become a journeyman plumber as well. You must also pass a specific journeyman licensure exam.
  • To become a master plumber in the state, you must have passed the journeyman license. The master's license can be taken in the same year, and this exam encompasses everything from tax law to drainage systems to best installation practices.

A plumbing license issued in the state expires the year it was issued, so any license issued in December must be immediately renewed for January the following year. A failure to renew a license requires a plumber to restart at the journeyman level and take the exams again.
