How to check a plumber's license in South Carolina

A quick check before anyone starts work: where to look the license up, what to match on the record, and what a license can't tell you.

Who licenses residential plumbers in SC?

The South Carolina Department of Labor, Licensing and Regulation (SC LLR). Its Residential Builders Commission issues residential plumber licenses and also regulates other residential credentials, such as specialty registrations, which are not the same as a plumbing license. Commercial plumbing work is licensed separately. SC LLR says residential plumbing work above a set dollar amount requires a license, so check before you hire.

1. Check the license in six steps

  1. Ask for the license number and the exact name it's issued under: the person's name, the business name, or both.
  2. Look it up on SC LLR's site. Open SC LLR's residential plumbing page and use its Licensee Lookup link.
  3. Match the name on the record to the name on your written estimate or contract. If they don't match, ask why.
  4. Check the type. Is it a residential plumbing license, or another credential such as a registration or a different trade? Ask whether it covers your job.
  5. Check the status. It should be active and current, not expired, lapsed or suspended. Licenses must be renewed.
  6. Keep a record. Note the license number and the date you checked, and put the number in your written contract.

2. What a license doesn't tell you

  • It isn't insurance. Ask for proof of insurance separately. The FTC suggests considering only licensed and insured contractors.
  • It isn't a quality guarantee. A current license shows the person met the state's requirements. It doesn't rate their work or their prices.
  • It isn't a permit. Permits come from your city or county. See who issues plumbing permits in the Upstate.

3. Red flags to watch for

The FTC lists these warning signs for home repair scams:

  • Pressure to decide right away.
  • Asking you to pay for everything up front, or accepting cash only.
  • No written estimate or contract. A written estimate should describe the work, the materials, the completion date and the price.

When it isn't an emergency, get more than one written estimate, and don't automatically pick the lowest bid. Hold the final payment until the work is done and you're satisfied.

4. If the lookup doesn't work

Online lookups sometimes change or go down. If you can't find the record, contact SC LLR through its official website, and ask the plumber for a copy of their license card or certificate in the meantime. Don't let work start until you're satisfied.
