What happens if my plumbing license expires?
The first thing you should do if you think your Indiana plumbing license has expired is to stop providing services and check your license status at the licensing agency’s online portal.
Working with an expired license is one of many forms of professional misconduct which may result in probation, suspension, and even the revocation of your plumbing license.
For licenses that have been expired for less than 3 years, all you need to do is renew online. If your license has expired for more than 3 years, you’ll need to apply for reinstatement, provide a letter of work history, and pay the associated fees. The fees you need to pay change depending on the current license you hold:
- Plumbing apprentice license reinstatement: $20
- Journeyman plumber license reinstatement: $60
- Plumbing contractor license reinstatement: $150
