If you are asking who installs gas lines, the answer is a licensed plumber. These pros install lines and gas valves, maintain licensing and insurance per local laws, and pull permits before work begins. Natural gas is highly flammable, so mishandling can cause explosions or carbon monoxide leaks.

Get at least three quotes before you decide who to hire. Plumbers can install natural gas or propane lines—just specify your fuel type during the hiring process. You can also schedule annual inspections with a plumber or your local gas company to catch hidden issues and prevent early replacement.

Benefits of Hiring a Plumber to Install Gas Lines

Installing gas lines is best left to a licensed plumber who follows permit and safety protocols. Pros plan routing, choose appropriate materials, and complete inspections to minimize risk. Professional installation supports safe appliance operation and long service life.

When hiring a local plumber, you can expect them to:

• Shut off the supply and ensure proper ventilation during work

• Determine safe routing and select the correct materials

• Dig and backfill trenches for underground gas runs

• Connect lines and verify system integrity with inspections

• Check appliance and home connections for safe operation

• Install propane gas lines when specified and carry insurance

If you’re unsure about handling gas line work yourself or want to ensure everything is up to code, consider hiring a local plumber to guarantee the job is done safely and professionally.

Can I Hire a Local Gas Company for Gas Line Installation?

Local gas companies can inspect your gas lines annually to detect leaks or other hazards. These safety checks help detect hidden issues and offer peace of mind. 

For installation and permitting, you still need a licensed plumber who handles permits and complies with local laws. Use the gas company for routine inspections and a plumber for the actual installation to keep responsibilities clear and safety prioritized.
