Why Do Plumbers Need a License in Most States?

Plumbing is an essential part of your day-to-day life. When you hire a plumber to clean your drains, service your water heater or install a water softener, you want the assurance of a job well done. While reading reviews and learning more about the company’s years of experience can help, the number one thing to look for is a plumbing license. 

Only six states — Kansas, Missouri, Nebraska, New York, Pennsylvania and Wyoming — don’t issue plumbing licenses at the state level. Instead, they count on city and county governments to provide oversight and licensing. While the exact requirements to earn a plumbing license vary by region, you can be certain that hiring a licensed specialist is the best way to minimize the chance of poor workmanship, fraud and health problems. 

Educational Requirements for Plumbers 

Here’s what it takes to become a licensed plumber: 

  • Education: Many vocational schools and community colleges offer plumbing certificates or degrees. Usually this training covers all the necessary skills plumbers use on a regular basis. 
  • Apprenticeship: Both union and non-union organizations offer apprenticeship courses that combine classroom learning with hands-on experience. These programs typically last four to five years, and apprentices receive wages throughout their training. 
  • Licensing exam: Each state offers its own plumbing exam, which candidates must pass to receive a license. The topics covered include plumbing fixtures, drainage systems, vents and venting, fabrication, pipe maintenance, administrative procedures and more. Qualifications to take the exam vary by state and licensing level. 

Types of Plumbing Licenses and Certifications 

Plumbers can receive different licenses and certifications based on their knowledge and experience. These vary by location, and not all are offered in every state, but the most typical plumbing licenses and certifications include: 

  • Plumbing certificate: Some states only require plumbers to have a certificate to work on residential jobs with a limited scope of work. This is ultimately an apprentice-level plumber working with supervision. 
  • Journeyman plumber: In most states, plumbers can take the journeyman’s licensing exam after completing an apprenticeship and having four years of practical experience. 
  • Master plumber: The requirements to take the master plumber’s licensing exam vary significantly by location. Some states only require one or two years working as a journeyman plumber, while others call for four or five years of journeyman experience. 
  • ACE certification: Progressing to an Advanced Certified Expert demonstrates the maximum level of professionalism and experience. Earning ACE certification is more stringent than most plumber licensing and requires yearly recertification to keep technicians up-to-date with the most recent industry standards. 

Benefits of Hiring a Licensed Plumber 

Choosing an unlicensed plumber for the job could save you a few dollars up front, but that’s where the benefits end. Don’t risk it — only hire a licensed pro, no matter the job, to ensure all the perks of professional experience: 

  • Excellent workmanship: Plumbing is not an easy field. Performing even the most straightforward projects, like snaking a drain, requires specialized equipment and years of experience. Given the amount of training needed to achieve their certifications, you can rest assured that a licensed plumber has what it takes for a job well done. 
  • Liability insurance: Most states require plumbers to show proof of liability insurance as part of the licensing process. This prevents you, the homeowner, from being held liable for property damage or medical bills if a plumber has an accident while performing services in your home. 
  • Legal and code-compliant: Major plumbing jobs often require permits to ensure safety and legality. Unlicensed plumbers are typically denied the required permits. If they go ahead with the job, you could face code violations and fines later on. Similarly, you could face legal consequences if an unlicensed plumber damages the local waterways. Remove these risks by only hiring a licensed professional. 
  • Preserved health and safety: A qualified plumber understands the proper techniques for working on water supply lines, sewer pipes and gas lines. Years of hands-on experience are necessary to reduce the risk of water contamination, sewer backups and gas leaks. 
  • Legitimate services: Some plumbers don’t have your best interest at heart. But a fully licensed team is much less likely to attempt to scam you than an unlicensed company. After all, homeowners can make a formal complaint with the state licensing board if they suspect fraud, leaving the plumber with a steep fine or even causing them to lose their license. Knowing this provides extra peace of mind when hiring a plumber for the first time.
