Can i start my own plumbing business without a masters or journeymen license?

I have been doing plumbing for about 7 years and want to start doing work for myself.I want to know what options do i have.I want to put out business cards for myself.I completed the apprenticeship program for plumbing.I received a certificate from the state of Florida certifying me as a plumber.It also gave me an id number.I want to know if this certificate is enough or do i need more to start,operate and run my own business.If anyone knows please help.

You'd better check with your state licensing board. States differ in their requirements.

 

As quoted above, you need to check what are the basics needed for your jurisdictions. Many plumbers need a certification for domestic water and waste systems. Many plumbers also need a gas certification before they can even touch a gas line! I wouldn't doubt you need to take a test from the State of Florida to become a licensed contractor.
