Choose a Marietta plumber who holds an active Georgia plumbing license, carries liability insurance, pulls the required permit and gives a written price before work starts. Verify the license number on the Georgia Secretary of State website before hiring.

A licensed plumber is a tradesperson who has met Georgia’s experience and exam requirements and holds an active license from the state licensing board. The license confirms training in the Georgia plumbing code. Our licensed Marietta plumbing company lists its license number on every estimate.
Why Does a Plumbing License Matter in Georgia?
A Georgia plumbing license matters because it confirms the plumber passed a state exam, met experience requirements and works under the state plumbing code. Licensed work passes permit inspections and protects the home’s insurance coverage.
Georgia licenses plumbers through the State Construction Industry Licensing Board, Division of Master Plumbers and Journeyman Plumbers. Unlicensed work risks failed inspections, code violations and repairs that must be redone.
What Are the Georgia Plumbing License Types?
Georgia issues 3 plumbing license types: Journeyman Plumber, Master Plumber Class I (restricted) and Master Plumber Class II (non-restricted).

| License | Scope | Experience required |
|---|---|---|
| Journeyman Plumber | Plumbing work under the state code | At least 1 year |
| Master Plumber Class I | Restricted license for limited types of work | At least 5 years, 2 as a licensed plumber |
| Master Plumber Class II | Non-restricted, including commercial and industrial work | At least 5 years, 2 as a licensed plumber |

- What is your Georgia license number?
- Do you carry liability insurance?
- Who pulls the permit for this job?
- What does the written price include?
- What warranty covers parts and labor?
- Who does the work: a licensed plumber or a helper under supervision?
What Are the Red Flags When Hiring a Plumber?
The 6 red flags are no license number, no written price, cash-only payment, pressure tactics, a large deposit and an offer to skip the permit.
- No license number. A licensed plumber shares it.
- No written price. Verbal quotes change after the work.
- Cash only. No payment record and no recourse.
- Pressure tactics. “Today only” pricing on non-emergency work.
- Large deposit. A big upfront payment on a small repair.
- Skipping the permit. Unpermitted water heater, gas or sewer work fails home sale inspections.
How Do You Hire a Plumber in an Emergency?
Hire an emergency plumber by first shutting off the water, then calling a licensed company with 24/7 service and asking for the after-hours rate before dispatch. Emergency rates run higher than business-hours rates.
