The path of a plumber in Maine has 4 stages:

  • Journeyman-in-training license
  • Journeyman plumber
  • Master plumber

Becoming a Plumber Trainee

In Maine, plumber trainees are actually the apprentices who seek to become licensed plumbers.

They learn the trade while working under a journeyman or master plumber who teaches them how to perform various tasks.

Some of the tasks might be performed by these trainees while not being supervised.

They will need a license as well.

To obtain it, you’ll need to provide proof of working with a journeyman or master plumber as a trainee.

Additionally, you’ll also need the following documents:

  • A filled-out application
  • Paying the application fee – $25
  • Paying for the license – $200
  • Passing the criminal background check
  • Paying for the background check – $21

Becoming a Journeyman-in-Training

Those who want to pursue a career in plumbing and enroll in a vocational school can apply for this license.

This license is only valid for 4 years and cannot be renewed.

These individuals will be allowed to work with a master plumber after:

  • Completing 2 semesters of classroom education
  • Passing the journeyman exam

The exam costs $75.

The minimum score accepted for this exam is 70%.

The exam is organized through Prov Inc, and this institution can offer more details regarding the exam itself.

The exam can be taken at any location across the nation and the results are learned on the spot, at the end of the examination.

Obtaining the Journeyman Plumber License

After completing either one of the previous steps, you’re eligible to become a journeyman plumber.

Plumber trainees need to complete 4,000 hours in 2 years, while the journeymen-in-training need to complete at least 2,000 hours of experience.

They need to accumulate this many hours within 4 years of obtaining the journeyman-in-training license.

In Maine, these professionals need to be supervised by a master plumber while performing plumbing installations.

The requirements to obtain the license are very similar to those for the journeyman-in-training license.

These are:
