As with other skilled trades, most states require training and professional licensing before you can legally install, repair, and maintain plumbing systems. While the plumbing trade has been around since the 1800s, today’s plumbers need a wide range of skills to work in residential and commercial settings. Depending on the nature of the job, plumbers often work alongside electricians, HVAC techs, general contractors and other professionals in the construction industry.

Learning the art of plumbing takes years, but once you complete the necessary training, your skills will be in high demand across New Mexico and beyond.
