Common Licensed Plumber Scenarios

Frequently Asked Questions
How do I verify a plumber's license in MD?
In MD, you can verify plumber licenses through the state licensing board website. All plumbers listed on our site are licensed. Plumbers below with the BBB badge have additional third-party accreditation and a public complaint record.
Why does BBB accreditation matter?
BBB accreditation means the plumber has agreed to resolve complaints, maintain honest advertising, and meet trust standards. It's not a guarantee of quality, but it adds accountability — the BBB tracks complaints and resolution rates publicly.
Are all plumbers in Dundalk licensed?
By law, plumbers performing work in Baltimore County must be licensed. However, some unlicensed handymen advertise plumbing services illegally. Hiring an unlicensed plumber voids insurance claims and can create permit issues when selling your home.
What's the difference between a journeyman and master plumber?
A journeyman plumber has completed an apprenticeship and passed the licensing exam. A master plumber has additional years of experience and can pull permits, supervise journeymen, and run a plumbing business. Both are qualified for residential work.
