If you’ve ever wondered, “Do plumbers deal with gas lines, or is that someone else’s job?” — you’re not alone. Many homeowners think plumbers only work on water systems, drains, and toilets.

Knowing when a plumber can handle your gas lines isn’t just a matter of convenience — it’s a safety necessity. In this guide, you’ll learn exactly when plumbers deal with gas lines, what qualifications they need, the safety rules involved, and how to choose the right professional for your home.

Do Plumbers Deal with Gas Lines? What Every Homeowner Should Know
Yes. Many licensed plumbers are trained and certified to install, repair, and maintain natural gas lines. However, this work requires specific qualifications and strict compliance with local codes.
Key Point: Always confirm your plumber holds the correct gas work license for your area before hiring them.
Why Gas Line Work Falls Under Plumbing
Gas lines might not carry water, but they’re still part of your home’s piping system. In many plumbing codes, gas lines are treated as another branch of piping infrastructure, which is why certified plumbers can work on them.
Core Responsibilities of Gas-Certified Plumbers
Installing new gas lines for appliances like stoves, water heaters, dryers, or fireplaces
Extending or rerouting gas lines during renovations
Repairing leaks and replacing old pipes to meet safety standards
Performing pressure tests to confirm the system’s integrity before use
Local Licensing Note: Not all plumbers can legally work on gas lines. Some states require a separate gas fitter certification. Always check your local regulations.
When You Should Call a Plumber for Gas Lines
You should call a licensed gas-certified plumber for these situations:
1. New Appliance Installations
If you’re adding or replacing a gas-powered appliance, you’ll need a gas line hookup.
Examples:
2. Gas Leak Repairs
Signs of a leak:
Rotten egg smell (due to added odorant)
Hissing or whistling sounds near gas lines
Dead vegetation above buried lines
Action: Shut off your home’s main gas valve immediately and call a qualified professional. If you suspect a large leak, leave the property and contact your gas utility’s emergency line.

3. Upgrades and Code Compliance
Older gas lines may corrode, develop leaks, or fail modern safety codes. If you’re renovating, selling, or buying a home, a plumber can assess and upgrade your lines to pass inspection.
