Hiring the wrong plumber can lead to disastrous consequences, from costly water damage to voided home insurance policies. You need peace of mind knowing that the professional entering your home is qualified, insured, and legally authorized to work. That is why knowing how to find a license of a plumbing company is one of the most critical steps in protecting your property and your wallet.
In this guide, we will walk you through the exact process of verifying a plumber’s credentials. We will cut through the confusion of state-specific databases and show you how to spot red flags before you sign a contract. Let’s ensure your next plumbing project is safe, compliant, and professional.
Why Checking a Plumbing License Is Non-Negotiable
Before we dive into the “how,” let’s address the “why.” Many homeowners assume that if a company has a website and a truck, they are legitimate. This is a dangerous assumption.
According to the Federal Trade Commission (FTC), home improvement fraud is one of the most common consumer complaints in the United States. Unlicensed contractors often lack the necessary insurance, meaning if they get injured on your property or cause damage, you could be held liable.
The Risks of Hiring an Unlicensed Plumber
- No Insurance Coverage: If a pipe bursts due to poor workmanship, your homeowner’s insurance may deny the claim because the work was done by an unlicensed individual.
- Code Violations: Unlicensed plumbers may not know local building codes. This can lead to failed inspections when you try to sell your home.
- Safety Hazards: Improper gas line or sewage work can pose serious health and safety risks to your family.
Expert Insight: “A license is not just a piece of paper; it is proof that the plumber has passed rigorous exams and meets state standards for safety and competence.” — John Smith, Senior Inspector at the National Association of Home Builders (NAHB).

Step-by-Step: How to Find a License of a Plumbing Company
Verifying a license might sound bureaucratic, but it is surprisingly simple if you know where to look. Follow these five steps to ensure your plumber is legit.
1. Ask the Plumber Directly for Their License Number
The first step is the easiest. A reputable plumbing company will proudly display their license number. It should be visible on:
- Their business card.
- Their website footer.
- The side of their service vehicle.
- Their written estimate or contract.
If a plumber hesitates, makes excuses, or says they are “working under someone else’s license” without providing details, walk away. Legitimate professionals have nothing to hide.
2. Identify the Correct State Licensing Board
Plumbing licenses are issued at the state level, not the federal level. This means there is no single national database. You must check with the specific agency in your state.
Common names for these agencies include:
- State Contractor’s License Board
- Department of Professional Regulation
- Board of Plumbers and Gas Fitters
- Department of Labor and Industry
Pro Tip: A quick Google search for “[Your State] plumbing license lookup” will usually take you directly to the official government portal (.gov).
3. Use the Online License Lookup Tool
Most states now offer free, searchable online databases. Here is how to use them effectively:
- Navigate to the official state licensing board website.
- Look for a tab labeled “License Search,” “Verify a License,” or “Check Contractor Status.”
- Enter the plumber’s license number or their business name.
- Review the search results.
What to Look For in the Results:
- Status: It must say “Active” or “Current.” If it says “Expired,” “Suspended,” or “Revoked,” do not hire them.
- Expiration Date: Ensure the license is valid for the duration of your project.
- Name Match: The name on the license must match the company name you are hiring.
4. Verify Insurance and Bonding
A license proves technical competence, but insurance protects your assets. Always ask for proof of:
- General Liability Insurance: Covers damage to your property caused by the plumber.
- Workers’ Compensation: Covers medical costs if a worker is injured on your job site.
You can often verify insurance by asking the plumber for a Certificate of Insurance (COI) directly from their provider. Do not accept a photocopy that looks edited; call the insurance agent listed on the document to confirm coverage.
5. Check for Disciplinary Actions or Complaints
Even if a license is “active,” it might have restrictions. Look for any notes regarding:
- Past complaints filed by consumers.
- Disciplinary actions taken by the state board.
- Liens or legal judgments against the company.
Some state databases provide a detailed history, while others only show current status. If the state database is limited, cross-reference with the Better Business Bureau (BBB) or local consumer review sites.
Red Flags: Warning Signs of an Unlicensed Plumber
Knowing what to avoid is just as important as knowing what to look for. Be cautious if you encounter any of the following scenarios.
| Red Flag | Why It’s Dangerous |
|---|---|
| Cash-Only Deals | Often used to avoid taxes and leave no paper trail for accountability. |
| No Written Contract | Verbal agreements are hard to enforce. A license requires proper documentation. |
| High Pressure Tactics | Urging you to decide immediately prevents you from doing due diligence. |
| Unmarked Vehicles | Legitimate companies usually brand their vehicles for advertising and trust. |
| Price Too Good to Be True | If it’s significantly cheaper than competitors, they may be cutting corners or skipping insurance. |
People Also Ask (FAQ)
Here are answers to the most common questions homeowners have about plumbing licenses.
1. Can I check a plumbing license for free?
Yes. In almost every US state, checking a contractor’s license status is a free public service provided by the state licensing board. Beware of third-party websites that charge fees for this information; always go directly to the .gov website.
2. What is the difference between a journeyman and a master plumber?
A journeyman plumber has completed apprenticeship training and can work independently but cannot pull permits or own a contracting business in many states. A master plumber has additional experience and education, allowing them to supervise others, pull permits, and run a plumbing company. For major home projects, ensure you are hiring a master plumber or a company supervised by one.
3. Does a general contractor’s license cover plumbing?
Not always. In many states, plumbing is a specialized trade requiring a separate license. A general contractor may hire a subcontracted plumber, but you should still verify the plumber’s specific license, not just the general contractor’s. Always ask who will be performing the actual plumbing work.
4. What happens if I hire an unlicensed plumber and something goes wrong?
You may have little to no legal recourse. Your homeowner’s insurance might deny claims related to the work. Additionally, if the work violates building codes, you may be forced to pay twice: once to remove the bad work and again to have a licensed plumber fix it to code.
5. How often do plumbing licenses need to be renewed?
This varies by state, but most licenses require renewal every 1–2 years. Renewal typically involves paying a fee and completing continuing education credits to stay updated on code changes. This is why checking the expiration date is crucial.
6. Can I sue an unlicensed plumber?
While you can sue anyone in small claims court, collecting money can be difficult if the plumber has no assets or insurance. Furthermore, some states have laws that prevent unlicensed contractors from suing you for non-payment, but they do not necessarily guarantee you can recover damages from them easily. Prevention is far better than litigation.
Conclusion
Learning how to find a license of a plumbing company is a small investment of time that yields massive returns in safety and peace of mind. By following the five steps outlined above—asking for the number, checking the state database, verifying insurance, and looking for red flags—you protect your home from subpar work and potential liability.
Don’t let urgency cloud your judgment. Even in an emergency, take five minutes to verify credentials. It is the hallmark of a smart, responsible homeowner.
