Licensed Plumber in Tennessee: How to Verify Before You Hire

Plumbing work in Tennessee is regulated by a dedicated state licensing board with jurisdiction over all plumbing installations, repairs, and alterations statewide. Whether you're replacing a water heater, repiping a bathroom, or connecting a new fixture, the contractor performing that work must hold a valid Tennessee plumbing license. Here's how to verify one before you hire.

Does Tennessee require plumbers to be licensed?

Yes. Tennessee requires all plumbers to be licensed by the Tennessee Board of Plumbing Examiners under the Department of Commerce & Insurance at tn.gov/commerce. This requirement applies to all plumbing work statewide, regardless of project size or cost. There is no dollar threshold below which plumbing work can legally be performed without a license.

The Tennessee Board of Plumbing Examiners sets examination requirements, oversees license renewals, and handles disciplinary actions. It issues licenses to both individual plumbers and plumbing contracting businesses, and you can verify either through the state's online lookup.

What types of plumbing licenses does Tennessee issue?

Tennessee issues two primary plumbing license categories: Journeyman Plumber and Master Plumber. A Journeyman Plumber can perform plumbing work under the supervision of a licensed master plumber. A Master Plumber has the highest individual certification, can work independently, supervise journeymen, and operate a plumbing contracting business.

When hiring a plumbing company, the business must employ a licensed Master Plumber responsible for all work performed. When you verify credentials, confirm that the master plumber of record for your specific job holds an active license — not just that someone in the company does.

How do you verify a plumber's license in Tennessee?

Tennessee plumber licenses can be verified through the Department of Commerce & Insurance license lookup at tn.gov/commerce. Search by the plumber's or company's name or license number. The result will show the license type, current status, expiration date, and any formal disciplinary actions on record.

Verify on the day you hire. Licenses expire if renewal requirements are not met, and can be suspended or revoked for disciplinary reasons. A license that appeared valid at the time of your estimate may have changed status before the job starts.

Tennessee plumbers are required to include their license number on contracts and advertising. Ask for the license number at the beginning of your conversation with any plumbing contractor. A reluctance to provide it is worth investigating before you commit.

What bond and insurance should a Tennessee plumber carry?

Tennessee requires licensed plumbing contractors to post a $10,000 surety bond as a condition of licensing. The bond provides limited financial recourse if a contractor fails to complete work or causes unremedied damage. For larger plumbing jobs, you should also require general liability insurance beyond the bond.

Ask for a certificate of insurance showing active general liability coverage and workers' compensation insurance before work begins. Call the insurer to confirm both policies are currently in force. Workers' comp coverage is essential — a plumber injured in your home while working for an uninsured contractor could expose you to significant legal and financial liability.

What are the risks of hiring an unlicensed plumber in Tennessee?

The consequences of unlicensed plumbing work extend well beyond a bad repair. Faulty plumbing installations can contaminate drinking water, create sewer gas leaks that pose health hazards, and cause water damage leading to mold. Water damage is the second most common homeowner insurance claim in the United States, and improperly installed plumbing is a frequent cause.

Unlicensed plumbing work in Tennessee is unpermitted. Unpermitted work will fail required inspections and may need to be completely removed and reinstalled at your cost. Homeowner's insurance may not cover damage caused by unlicensed work, and lenders may require all plumbing work to be permitted before approving a mortgage on a home sale.

Recovering money from an unlicensed plumber is extremely difficult. Without a state license, there is no bond, no insurance requirement, and no regulatory body that can compel the contractor to make things right. Your best protection is verifying credentials before work begins.

What else should you confirm before hiring?

Beyond the license, check the Tennessee Board of Plumbing Examiners database for any disciplinary history. The board publishes formal enforcement actions and complaints publicly. An active license combined with a history of prior sanctions is still a risk worth weighing before you commit.

Confirm that your plumber will obtain the required plumbing permit from your local building or inspection department and schedule the post-installation inspection. Licensed master plumbers handle permit management as standard practice. If a contractor suggests skipping permits to save time or money, walk away.
