If you want to become a plumber in Delaware, the first thing to know is that you'll need proper training before you can get licensed. In Delaware, there's no shortcut. You need to complete either a formal apprenticeship or approved trade school program to qualify for your journeyman plumber license. Choosing the right training program now can save you time, money, and frustration later.

Below, we'll cover the best plumbing schools in Delaware, explain the state licensing process, and help you figure out your next step.


Understanding Delaware's Plumbing License Requirements

Delaware regulates plumbers through the Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners, which is part of the Division of Professional Regulation. The licensing process has clear requirements:

In Delaware, to become a licensed journeyman plumber you need at least seven years of verified experience or a combination of an approved apprenticeship and work experience that equals seven years.

There are two main paths:

  2. Trade or technical school training combined with work experience.

After your training and experience are complete, you must pass the state plumbing exam.

Steps to Get Your Plumbing License in Delaware

If you're starting from scratch, here's the general process you'll follow:

  1. Meet eligibility requirements
    Be at least 18 years old and have a high school diploma or GED.

  2. Enroll in an apprenticeship or trade program
    Choose a path that suits your schedule and financial situation.

  3. Log your work hours and training
    Delaware requires proof of training and experience before approving you for the exam.

  4. Apply for your journeyman plumber license exam
    Submit your application to the Delaware Division of Professional Regulation.

  5. Pass the exam
    You'll need to show your knowledge of plumbing codes, safety, and installation practices.

Additional Training and Certifications

Some plumbers in Delaware go beyond the basic journeyman requirements. You can add specialties like:

  • Backflow prevention certification
  • Gas fitting endorsement
  • EPA Section 608 for refrigerant handling (if you work in HVAC)

Adding extra credentials can make you more competitive for certain jobs.


Choosing the Right Program

When comparing plumbing schools or apprenticeships in Delaware:

  • Check if the program is state-recognized.
  • Ask about hands-on training hours.
  • Look at graduate job placement rates.
  • Compare costs and schedule options.

A common mistake is picking a program based on price alone. Quality training pays off in the long run because it gets you licensed faster and better prepares you for the exam.
