How do you check a plumbing license in Maine?

Use Maine’s individual license search for plumbing, under the Plumbers' Examining Board. Search by name or license number, then use the plumbing profession options to narrow your search. The board’s scope is people performing plumbing; Maine’s statutory definitions distinguish journeyman work from the master plumber’s business role.

Key facts

How can you look up a plumbing license in Maine?

Open the individual search for Maine’s Plumbers' Examining Board and use the name or license-number fields. The empty form labels them Last Name, First Name and License Number; its additional Profession choices include Journeyman, Master and Trainee. These are search-form options, rather than a description of any person’s record.

The state’s Licensee Search guide, read 5 November 2026, says: “You may search for a licensee (individual or company) by name or license number.” For its search sequence, the guide gives these instructions:

What plumbing license rule applies in Maine?

Maine’s individual-license rule is in Title 32, section 3302(1): “A license is required for any individual who is engaged in plumbing or performing plumbing installations. A license is not required for any activity for which a permit is not required under Title 30‑A, section 4215.” Read the complete applicability section, read 5 November 2026, for its listed exceptions.

Source: Maine Legislature, Title 32 section 3302 applicability, read 5 November 2026.

The individual wording is useful when deciding what to enter in the public search: the person’s name is distinct from a business name. Keep the statutory question and the search task separate; this page offers a route to the public source rather than a conclusion about a particular person or job.

Source: Maine Legislature, Title 32 section 3302 applicability, read 5 November 2026.

If you consult Maine’s individual plumbing rule, keep that optional research alongside the work description you prepare for a written request on InstaBids.

Can a homeowner do their own plumbing in Maine?

The personal-abode provision appears in section 3302(1)(C), within the section’s list of activities to which it does not apply: “Plumbing by a person in a single-family residence occupied or to be occupied by that person as that person's bona fide personal abode as long as the installation conforms with board laws and rules; and”. The quotation retains the ending that connects it to the following provision in the complete Maine statute, read 5 November 2026.

Source: Maine Legislature, Title 32 section 3302 applicability, read 5 November 2026.

Read that clause in its full context rather than treating a homeowner’s work and hired plumbing as interchangeable. The source speaks specifically about the person’s residence and conformity with board laws and rules. It does not answer every question about a proposed installation.

Source: Maine Legislature, Title 32 section 3302 applicability, read 5 November 2026.

When planning your scope on InstaBids, Maine’s personal-abode clause can inform your optional reading about which plumbing work you intend to describe.

What is a journeyman plumber in Maine?

Maine defines journeyman work in section 3301(3): “"Journeyman plumber" means any person who customarily performs the work of installing plumbing and drainage under the employment and direction of a master plumber or, not being a master plumber, does plumbing repair work as a regular part-time occupation.” The Maine definitions section, read 5 November 2026, supplies the exact scope.

Source: Maine Legislature, Title 32 section 3301 definitions, read 5 November 2026.

For comparison, section 3301(5) states: “"Master plumber" means any individual qualified under this chapter engaging in or about to engage in the business of installing plumbing or plumbing systems. The license must specify the name of the individual to whom the license is issued.” These are statutory definitions, rather than promises about a search result or the work a particular person will perform. Source: section 3301, read 5 November 2026.

The journeyman and master definitions in Maine give you vocabulary for describing the plumbing responsibilities in your own written request on InstaBids.

How can I file a complaint against a Plumber?

Use the Office of Professional and Occupational Regulation’s File a Complaint page, which is the destination linked by the plumbing board’s consumer FAQ. Its instruction is: “Please follow this link to complete an online complaint submission: Office of Professional and Occupational Regulation Online Complaint Form.” Open the agency complaint page, read 5 November 2026, and follow its submission link.

Source: Maine Office of Professional and Occupational Regulation complaint submission, read 5 November 2026.

The complaint destination is separate from the individual search. This guide provides the agency’s filing route; it does not report complaint counts, describe a disciplinary result or make a judgment about any plumber.
