How Pennsylvania licenses plumbers
There is no statewide plumber license; cities or counties license plumbers.
Businesses: Contractors who perform at least $5,000 of home improvement work per year must register with the Pennsylvania Attorney General's Office under the Home Improvement Consumer Protection Act.
Local rules: Plumbers are licensed locally, for example by the City of Philadelphia Department of Licenses and Inspections and the Allegheny County Health Department (master, journeyman and apprentice plumbers).
Ask your municipality whether it licenses plumbers, confirm the local license where required, and verify the contractor's home improvement registration with the Attorney General's Office (hotline 1-888-520-6680).
We could not confirm every detail from Pennsylvania’s own sources, so treat this as a starting point and check with the agency.

Before you hire
Ask for the license number and check it on the official lookup where one exists. Ask for proof of insurance and a written, itemized estimate, and ask who pulls the permit if the job needs one – water heaters, repiping and sewer lines often do.
