What are the Types of Plumbing Licenses in Missouri?

Usually, plumbing licenses are divided into four stages where you have to move from one to the next as you get eligible.

1. Apprentice

This is where it all begins. An apprenticeship license allows you to provide plumbing services under the supervision of a journeyman or master plumber.

2. Journeyman

As a licensed journeyman plumber, you can provide plumber services on your own while working for a plumbing business.

3. Master

A master plumbing license gives you the power to plan and supervise plumbing services, in addition to executing them yourself.

Remember that, in some regions, master and contractor are the same. Thus, a master plumber also allows you to take plumbing contracts and start your plumbing business.

4. Contractor

If you want to start your plumbing business, you will need to be licensed as a contractor. However, you don’t need to be a master to get licensed as one. You just need a master plumber on your team to represent your business.

Now, let’s take on various regions of Missouri and start your plumbing journey.
