Hiring the wrong plumber or gasfitter can lead to costly repairs, safety hazards, or even legal trouble. If you’re in Maryland and need plumbing or gas work done, knowing how to verify a journeyman plumber and gasfitter in Maryland isn’t just smart—it’s essential. Whether you’re a homeowner, property manager, or business owner, this guide walks you through every step to confirm credentials fast and confidently.
Why Verifying a Journeyman Plumber & Gasfitter Matters
In Maryland, plumbing and gasfitting are highly regulated trades. According to the Maryland Home Improvement Commission (MHIC), unlicensed contractors account for nearly 20% of consumer complaints annually—many involving substandard work or outright fraud.
A licensed journeyman plumber and gasfitter has:
Completed 4+ years of apprenticeship training
Passed rigorous state exams
Met continuing education requirements
Carried liability insurance (in most cases)
Verifying their license ensures they meet these standards—and protects you from fines, unsafe installations, or voided insurance claims.
💡 Fun fact: In 2023, the Maryland Board of Plumbing issued over 1,200 enforcement actions against unlicensed individuals—a 15% increase from 2022 (source: Maryland Department of Labor).
Step-by-Step: How to Verify a Journeyman Plumber and Gasfitter in Maryland
Follow these 5 precise steps to confirm someone is legally authorized to perform plumbing and gas work in Maryland:
1. Ask for Their License Number
Before doing anything else, request their Maryland Master or Journeyman Plumber/Gasfitter license number. Legitimate professionals will provide this willingly—it’s usually printed on business cards, trucks, or invoices.
🔍 Tip: A journeyman license number in Maryland typically starts with “P” (for plumber) or “G” (for gasfitter), followed by digits (e.g., P123456).
📉 Stat: Between 2021–2025, 68% of revoked plumbing licenses in MD were due to unpermitted gas line installations—a serious fire risk.
5. Verify Insurance & MHIC Registration (For Home Projects)
If the job involves home improvement (e.g., bathroom remodel, new water heater), the contractor must also be registered with the Maryland Home Improvement Commission (MHIC).
Confirm their MHIC license is active and in good standing
✅ Note: Journeyman-level workers often work under a master plumber’s MHIC license—but always confirm who is legally responsible for the project.
Common Mistakes Homeowners Make When Hiring Plumbers
Avoid these pitfalls that could cost you time, money, or safety:
Mistake
Risk
How to Avoid
Assuming “licensed” = “insured”
No coverage if they damage your pipes
Ask for proof of liability insurance
Hiring based on online ads alone
Fake reviews or unlicensed operators
Always verify via state portal
Skipping permit checks
Fines up to $1,000 + forced rework
Confirm permits are pulled by the contractor
Confusing apprentice with journeyman
Inexperienced worker doing complex jobs
Check license level explicitly
🧠 Pro insight: According to the National Association of Home Builders, homes with unpermitted plumbing work sell for 7–12% less—and buyers often demand full system replacements.
What’s the Difference Between a Journeyman and a Master Plumber in Maryland?
Understanding license tiers helps you hire the right person:
Apprentice: In training (must work under supervision)
Journeyman Plumber/Gasfitter: Can work independently but cannot pull permits or run a business
Master Plumber/Gasfitter: Can supervise, pull permits, own a company, and design systems
🛠️ Real-world example: If you’re replacing a water heater, a journeyman can do the install—but only a master can file the permit with your county.
Q1: Can I verify a plumber’s license over the phone?
A: Yes—but it’s slower and less reliable. Call the Maryland Board of Plumbing at (410) 230-6350. However, the online portal is faster, free, and available 24/7.
Q2: What if the license is “Inactive”?
A: An inactive license means the holder hasn’t renewed it or met continuing education requirements. They cannot legally work until reactivated. Do not hire them.
Q3: Are out-of-state plumbers allowed to work in Maryland?
A: Generally, no. Maryland does not have reciprocity with most states. Even licensed plumbers from Virginia or DC must obtain a Maryland-specific license.
Q4: How often do journeyman licenses expire?
A: Every 2 years. Renewal requires 8 hours of continuing education, including code updates and safety training.
Q5: What should I do if I find an unlicensed plumber?
A: Report them to the Maryland Department of Labor via their online complaint form. You may also file a report with your local county code enforcement office.
Q6: Is a journeyman plumber allowed to work alone?
A: Yes—for repairs, installations, and maintenance. But they cannot operate a plumbing business or pull permits without a master plumber overseeing the job.
Conclusion: Protect Your Home with One Quick Check
Knowing how to verify a journeyman plumber and gasfitter in Maryland takes less than 2 minutes—but can save you thousands in damages, legal fees, or safety risks. Always use the official state portal, confirm gasfitting credentials separately, and never skip the MHIC check for home projects.
Your peace of mind is worth it.
