Why Is It Important to Hire a Licensed and Insured Plumber?
What Risks Do Unlicensed or Uninsured Plumbers Pose?
Unlicensed work can fail inspection, void a permit, or create code violations that become the homeowner’s problem to fix later. Without insurance, homeowners have little recourse if a plumber damages their property or gets injured while working in their home.
How Does Licensing and Insurance Protect Homeowners?
A license means the plumber has demonstrated the required training and passed the state’s testing standards, giving you some baseline assurance of competence. Insurance shifts the financial risk away from the homeowner – if something goes wrong, the plumber’s coverage is what pays for it, not your homeowner’s policy.
What Are Plumbing Licenses and How Can I Verify Them?
What Types of Plumbing Licenses Should I Look For?
In Delaware, plumbing licenses generally fall into three tiers: Apprentice, Journeyman, and Master Plumber. A Master Plumber license Delaware issues is the one that allows a contractor to pull permits and operate a plumbing business independently, so it’s the credential worth confirming for any company you hire.
How Do I Check a Plumber’s License Online or via State Boards?
The Delaware Division of Professional Regulation plumber licensing lookup offers a free online license verification tool through its Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners at dpr.delaware.gov. You can search by name or license number to confirm a plumber’s license is current and see whether any disciplinary actions are on file.
How Do I Confirm a Plumber Is Properly Insured?
What Insurance Types Are Essential for Plumbers?
General liability insurance, which covers property damage or injury caused during a job, is the baseline coverage to look for. Workers’ compensation insurance is also important if the company has employees, since it protects you from liability if a worker is injured on your property.
How Can I Request and Verify a Certificate of Insurance (COI)?

A Certificate of Insurance plumber companies provide is a standard document that lists a contractor’s coverage types, limits, and expiration dates – any legitimate plumbing company should be able to provide one without hesitation. If you want extra assurance, you can call the insurance carrier listed on the COI directly to confirm the policy is active.
What Additional Steps Should I Take Beyond License and Insurance Checks?
How Can Reviews and Reputation Help Confirm a Plumber’s Credibility?
Online reviews, Better Business Bureau listings, and referrals from neighbors can help round out the picture beyond license and insurance alone. A consistent pattern of positive feedback – or consistent complaints – tells you something a license number by itself won’t.
What Red Flags Indicate an Unlicensed or Uninsured Plumber?
- Reluctance or refusal to share license or insurance information
- Only accepting cash and avoiding a written estimate or contract
- No permanent business address or verifiable phone number
- Pressure to start work immediately without a permit, when one is required
How Do Local and State Requirements Affect Plumber Licensing and Insurance?
Do Plumbers Need City or County Business Licenses?
In addition to a state plumbing license, many municipalities require a separate local business license or registration to legally operate within city or county limits. It’s worth confirming both are current, since a valid state license doesn’t automatically mean local requirements are met.
How Do Local Permits Impact Plumbing Verification?
Certain plumbing jobs – like sewer line replacement or water heater installation – require a permit pulled by a licensed contractor before work begins. If a plumber is willing to skip the permit process entirely, that’s often a sign they aren’t operating with a valid license in the first place.
What Are the Best Practices for Verifying a Plumber’s Credentials Efficiently?
What Is the Step-by-Step Process to Verify a Licensed and Insured Plumber?

- Verify the license status through Delaware’s Division of Professional Regulation online lookup
- Request a Certificate of Insurance and confirm it’s current
- Check reviews and any complaints filed with the Better Business Bureau

Where Can I Find Reliable Online Verification Tools and Resources?
Delaware’s Division of Professional Regulation (dpr.delaware.gov) is the official source for verifying a plumber’s license status and disciplinary history. The Better Business Bureau is a useful secondary resource for checking a company’s complaint history and overall reputation.
