Do plumbers need a license in New Jersey?

Yes. Plumbing may only be done by a licensed master plumber, an authorized plumbing contractor, or employees paid on a W-2. The State Board of Examiners of Master Plumbers issues the licenses, and they are renewed every two years.

How can I tell if a plumber is licensed?

Look the plumber up on the New Jersey Division of Consumer Affairs License Verification System at newjersey.mylicense.com. Licensed plumbers also have to show the master plumber's name and the plumbing license number on both sides of their commercial vehicles.

Do I need a permit to replace a water heater?

Yes. Replacing a water heater with a new one of like capacity counts as "minor work" under the state construction code. The work can start once the local construction office has been notified. A permit application follows within five business days, and the work is inspected.

Do these plumbers only serve Monmouth County?

Not always. Several companies also list Ocean County or broader Central Jersey coverage. Check each card and the company's own website.

How are plumbers picked for this list?

We start with owner submissions, our own research and open data (credited on our Data Sources page). We check every pick against the business's own website, and we never copy reviews or ratings from other sites. Sponsored listings are always clearly labeled.

How do I add or claim my plumbing business?

You can add your business on the free Starter plan in a few minutes. If it's already listed, open its page and use the claim link. To compare upgrades, see the pricing page.
