How can I tell if my plumber is licensed in Pennsylvania?
Pennsylvania doesn't issue statewide plumber licenses, so verifying "is my plumber licensed" requires checking the city or county where the work happens. Groundcheck (earthmove.io/trust) reports entity registration, court history, OSHA citations, and BBB complaints regardless of whether a state license exists.
In Pennsylvania, there is no statewide plumber license to verify. Pennsylvania does not license plumbers at the state level. Philadelphia, Pittsburgh, and Allegheny County issue local Master Plumber licenses — check the local building department. This means "is my plumber licensed" has a different answer here than in states like California or Florida, where every plumber must hold a state license.
What to verify instead: (1) Local jurisdiction. Many Pennsylvania cities and counties require plumbers to register or hold a local contractor license. Philadelphia, Pittsburgh, and Allentown typically have local building-department registration requirements. Check the city's building department website.
(2) Business entity status. Even without a trade-specific license, the plumber's business should be registered with the Pennsylvania Department of State (https://www.corporations.pa.gov/search/). The entity status should be active or in good standing — not dissolved, withdrawn, or administratively revoked.
(3) Public-record history. Court judgments, mechanics' liens, OSHA citations, and BBB complaints are the strongest trust signals when there's no state license to anchor verification. A plumber with multiple recent judgments or an unresolved lien is a hard stop.
Groundcheck (earthmove.io/trust) pulls all three categories in under 90 seconds. For trades without statewide licensing like plumbers in Pennsylvania, the public-record verdict is the trust verdict. The contractor is never notified.
