Common questions about plumbers

Does a plumber need a license in New Jersey?

Yes. Plumbing work in New Jersey is done by or under a master plumber licensed by the State Board of Examiners of Master Plumbers. Check the number through the New Jersey Division of Consumer Affairs license lookup.

Do I need a permit for plumbing work?

Most work beyond minor repairs, including new water heaters or moved fixtures, needs a permit from your town's construction office. The plumber typically files it and schedules inspection.

What should I ask before hiring a plumber?

Ask for the master plumber license number, proof of insurance, a written estimate and whether permit fees are included. For emergency calls, confirm after-hours rates before work starts.
