How plumbing licenses work in Maine
Maine licenses plumbers through the Plumbers' Examining Board, part of the Office of Professional and Occupational Regulation. State law (32 M.R.S. §3302) requires a license for anyone engaged in plumbing, and cities and towns can't require their own separate plumbing license. License levels include master, journeyman, journeyman-in-training and trainee. The one exception is a person doing plumbing in a single-family home they live in or will live in, as long as the work meets the board's rules.
Oil burner and propane and natural gas work is licensed separately by the Maine Fuel Board, which offers free license verification online. For a boiler or a gas water heater, ask about both licenses.
Permits are a good sign
Under Maine law (30-A M.R.S. §4215), installing plumbing in a building requires a permit from the local plumbing inspector, and a town can't issue one unless the applicant complies with the state's licensing law. A plumber who brings up the permit on their own is usually one who does things properly. One who suggests skipping it on a job that needs one is a red flag.
Where to check a plumber's reputation
- Online reviews: read the recent ones, look for details about jobs like yours and see how the company responds to complaints.
- The Better Business Bureau: check for complaints and how they were resolved.
- People you know: neighbors, landlords and property managers hire plumbers often.
- The license itself: confirm it's current with the state.
Red flags
- no license number, or a vague answer when you ask for one
- a price that's only given after the work is done
- pressure to decide on a big replacement on the spot
- cash only, with no written invoice
- a suggestion to skip a permit the job needs
Questions to ask before you hire
- What's your Maine license number, and who will do the work?
- How do you charge: flat rate or hourly, and is there a service call fee?
- Does this job need a permit, and will you pull it?
- What warranty covers the parts and the labor?
