Yes, most states require a plumber to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations. Check our state licensing tool to review the local plumber guidelines.

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification, which include:

• The owner, principal, or relevant manager passed a criminal background check

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

Local codes often mandate specific fittings, permits, and vent considerations for permitted function and safety, which are enforced by professionals.

Pipefitting is a more specialized profession, and pipefitters work with complex systems and low- and high-pressure pipes, so it can be considered harder than plumbing. Though each profession comes with its challenges, the nature of pipefitting requires working with heavier materials in fast-paced and dangerous environments, which can be more challenging than working on residential and commercial plumbing systems.

The size of a pipe isn’t always the outside or inside diameter. Rather, it’s a nominal diameter that depends on the type of pipe. For male pipes, you’ll need to measure the outside diameter. For female pipes, you’ll need to measure the inside diameter. You’ll then need to use a nominal diameter conversion chart to get the actual pipe size you’d buy in the store.
