From coastal vacation properties and historic downtown buildings to new residential subdivisions and commercial complexes, licensed plumbers are needed everywhere in the state. This guide covers what Maine plumbers earn at every career stage, the factors that drive pay differences, how to get licensed, and what the future holds for the trade.

Maine Plumber Salary Overview

However, experienced journeypersons and master plumbers in high-demand areas can earn well above $75,000 per year, and those who move into contracting or business ownership can earn six figures.

The plumbing trade in Maine encompasses a wide range of work: residential service and repair, new construction rough-in and trim, commercial plumbing, medical gas piping, fire suppression systems, and industrial process piping. Each specialty carries its own pay scale, with industrial and commercial work generally commanding a premium over residential service calls.

• Pre-Apprentice / Helper: $16 to $20 per hour. Individuals working alongside licensed plumbers before or during apprenticeship enrollment.
• Apprentice Plumber (Years 1-2): $19 to $24 per hour. Apprentices begin formal training and earn increasing wages as they advance through the program.
• Apprentice Plumber (Years 3-5): $24 to $32 per hour. Upper-year apprentices take on more complex tasks and receive higher compensation.

Key Factors That Affect Plumber Salaries in Maine

License Level

Maine's Department of Professional and Financial Regulation oversees plumber licensing. Moving up the license ladder, from apprentice to journeyperson to master plumber, directly increases earning power. Master plumbers who also hold a contractor license can bid and manage jobs, multiplying their income potential.

Industry Sector

Residential plumbing is the most common sector but tends to pay somewhat less than commercial or industrial work. Plumbers who specialize in medical gas systems, process piping for manufacturing facilities, or large-scale commercial HVAC hydronic systems can command significantly higher wages. The hospitality industry, which is large in Maine given its tourism economy, also generates steady demand for skilled commercial plumbers.

Union vs. Non-Union

The United Association of Plumbers and Pipefitters (UA) represents union plumbers in Maine, primarily through Local 788 and neighboring locals. Union plumbers benefit from collectively bargained wages that typically exceed non-union scales, along with health insurance, pension plans, and paid continuing education. Non-union plumbers may have more flexibility but must independently manage their own benefits and training.

Geographic Location

Portland and the greater Cumberland County area tend to offer the highest wages due to the volume of commercial and residential construction. Kennebec, Knox, and Androscoggin counties also show solid demand. Rural northern and eastern counties may offer lower base wages but can compensate with overtime, travel pay, and the relative ease of building a loyal customer base with limited competition.

Seasonal and Overtime Factors

Maine's construction season peaks in warmer months. Plumbers willing to work overtime during busy periods or respond to emergency service calls year-round can substantially increase their annual earnings. Service plumbers who handle emergency calls, frozen pipe repairs, and water heater failures during Maine winters are particularly valued and can charge premium rates for after-hours work.

How to Get Your Plumber License in Maine

Maine regulates plumbers through the Maine State Plumbing Board. The licensing pathway requires:

• Apprentice Plumber: Register with the Maine State Plumbing Board and work under a licensed journeyperson or master plumber. Apprentices must complete a state-approved training program combining 8,000 hours of supervised work experience with classroom instruction.
• Journeyperson Plumber: After completing the apprenticeship requirements, pass the state journeyperson exam. Journeypersons may work independently on plumbing installations and repairs.
• Master Plumber: After working as a licensed journeyperson for a minimum period (typically two years and 4,000 hours), pass the master plumber exam. Masters may pull permits and supervise apprentices.
• Plumbing Contractor: Business entities offering plumbing services must obtain a contractor license, which typically requires at least one licensed master plumber of record.

Apprenticeship Programs for Maine Plumbers

Formal apprenticeship is the primary route into the plumbing trade in Maine. Programs are typically five years long and combine paid work experience with 246+ hours of classroom training per year. Key providers include:

• UA Joint Apprenticeship and Training Committee (JATC): The union-affiliated apprenticeship program provides rigorous training across residential, commercial, and industrial plumbing. Graduates earn full journeyperson wages and are highly competitive in the job market.
• National Center for Construction Education and Research (NCCER): NCCER-certified programs are offered through some Maine vocational schools and contractors. These programs provide nationally recognized credentials alongside state license preparation.
• Employer-Sponsored Programs: Some larger plumbing contractors run state-approved apprenticeship programs. Quality varies, but reputable employers offer structured training that prepares apprentices for licensing exams.

Maine also has vocational programs at several high schools and adult education centers that introduce plumbing fundamentals, helping students decide whether the trade is right for them before committing to a full apprenticeship.

Plumbing Job Outlook in Maine

The Bureau of Labor Statistics projects that employment of plumbers, pipefitters, and steamfitters will grow by about 6 percent over the next decade, faster than the average for all occupations. Maine-specific drivers of demand include:

• Replacement of aging water and sewer infrastructure in older cities such as Portland, Lewiston, and Bangor.
• Residential construction in coastal and lake communities driven by remote-work migration.
• Expansion of healthcare facilities, which require specialized medical gas and process piping.
• Commercial development including hotels, restaurants, and retail in tourism-heavy regions.
• Growing adoption of high-efficiency water heating systems, including heat pump water heaters and tankless units.
• Increasing demand for gas line installation as natural gas and propane distribution expands in some areas.

Comparing Maine Plumber Salaries to Other New England States

Maine's plumber wages are competitive within the region, though not the highest:

• Massachusetts: Plumbers in Boston and eastern Massachusetts earn among the highest wages in the country, often 20 to 30 percent above Maine rates. Cost of living is correspondingly high.
• New Hampshire: Similar to Maine statewide, with a premium in the southern tier near the Massachusetts border.
• Vermont: Comparable wages to Maine. The market is smaller, limiting the number of large commercial projects.
• Connecticut: Higher wages than Maine, particularly in Fairfield County, but offset by higher living costs.
• Rhode Island: Higher median wages, reflecting the concentration of commercial work in and around Providence.

Tips for Increasing Your Plumber Income in Maine

Earn Your Master License

The single most impactful credential you can earn is a master plumber license. It opens doors to permit pulling, supervision roles, and independent contracting. Many master plumbers in Maine operate small businesses that generate substantially more than employee wages.

Develop a Commercial or Industrial Specialty

Medical gas certification (ASSE 6010 or equivalent), backflow preventer certification, and industrial process piping experience all command above-average pay. Healthcare facilities, breweries, food processing plants, and manufacturing operations are willing to pay premium rates for plumbers with specialized credentials.

Get Comfortable with Service Work

Service plumbers who handle residential and light commercial service and repair calls develop broad diagnostic skills and build client relationships. Over time, a loyal customer base can sustain a solo contractor or small shop with minimal marketing costs.

Stay Current with Code Changes

Maine adopts updated plumbing codes periodically. Plumbers who stay current with the Maine Plumbing Code and are familiar with energy-efficiency provisions, water conservation standards, and accessibility requirements are more valuable to employers and clients alike.
