How to Verify a Licensed Plumber in Vermont

Vermont requires plumbers to hold a Master Plumber license through the Vermont Office of Professional Regulation (sec.state.vt.us/professional-regulation) before supervising or contracting plumbing work. A $10,000 surety bond is required. Verifying a plumber's credentials at sec.state.vt.us takes two minutes and confirms you are hiring someone authorized to work in Vermont.

This guide covers Vermont's plumber licensing requirements, license tiers, how to verify credentials, and what else to confirm before signing a contract.

Does Vermont require plumbers to be licensed?

Yes. Vermont requires plumbers to hold a valid license through the Vermont Office of Professional Regulation (OPR) at sec.state.vt.us/professional-regulation. Vermont issues Master Plumber, Journeyman Plumber, and Apprentice Plumber licenses. Plumbing contracting businesses must also hold applicable registrations. Performing plumbing work without the required license in Vermont is a violation of state law and can result in fines and stop-work orders.

Vermont's plumbing licensing program ensures that plumbers have passed required exams and demonstrated the competency to perform safe, code-compliant plumbing work. The OPR maintains a public license database at sec.state.vt.us where consumers can verify any plumber's credentials for free.

Vermont's rural character means many homes rely on private well and septic systems. According to the Vermont Department of Environmental Conservation, improper well and septic connections are among the leading causes of waterborne illness risks in the state. Licensed plumbers are trained to make these connections correctly and in compliance with Vermont's environmental regulations.

What plumber license types does Vermont issue?

Vermont's OPR issues Master Plumber, Journeyman Plumber, and Apprentice Plumber licenses. A Master Plumber holds the highest individual license — authorized to supervise others, pull permits, and serve as the qualifying plumber for a licensed plumbing and heating contracting business. Journeyman Plumbers perform most field work under master oversight. Apprentices work under supervision in a training program.

Vermont plumbing license tiers:

• Master Plumber— Full authorization to supervise, design, and permit plumbing work. Required as the qualifier for plumbing contracting businesses in Vermont.
• Journeyman Plumber— Licensed to perform most plumbing work under master oversight.
• Apprentice Plumber— In a supervised training program. Cannot work independently.

Vermont's plumbing and heating licensing covers both plumbing and heating systems, recognizing the integration between these trades in Vermont's climate. Confirm the plumber's license covers heating work if your project includes hydronic heating or boiler systems.

What bond does a Vermont plumbing contractor need?

Vermont plumbing contractors must carry a $10,000 surety bond as a condition of their OPR license and Home Improvement Contractor registration. The bond protects consumers if the contractor fails to complete work or violates code requirements. Beyond the bond, verify active general liability insurance (at least $300,000 for residential projects) and workers' compensation. Confirm coverage is active by calling the insurer before any work begins.

How do I verify a plumber's license in Vermont?

Visit sec.state.vt.us/professional-regulation and use the OPR's public license lookup. Search under plumbing licenses by the plumber's name, business name, or license number. Confirm the license type (Master or Journeyman Plumber), the status is active, and the expiration date has not passed. Vermont plumbing licenses require periodic renewal — an expired license means the individual is not currently authorized.

What to verify in the search results:

• License type— Master for supervisors; Journeyman for field work.
• Status— Active. Expired or suspended means not authorized.
• Expiration date— Must be current.
• Business registration— Confirm the company also holds required HIC registration.
• Complaint history— Review any prior OPR disciplinary actions.

What permits are required for plumbing work in Vermont?

Most plumbing work in Vermont requires a permit from the local municipality or state plumbing inspection authority. For projects involving private wells or septic systems, additional permits from the Vermont DEC Wastewater and Potable Water Program may also be required. Your licensed plumber should obtain all required permits before starting work. Unpermitted plumbing can fail home sale inspections and void insurance coverage for related damage.
