Gas leak repairs FAQs

Yes, most states require a plumber to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations. Check our state licensing tool to review the local plumber guidelines.

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification, which include:

The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

Fixing a gas leak costs about $45 to $150 per hour for a plumber or gas line specialist. The job’s overall cost will vary depending on the location of the leak. A leaky junction or connection behind the stove or dryer will likely cost about $120 to $170. But for a leak that requires a gas fitter or plumber to excavate a pipe in the yard, the cost could rise to $1,500 to $5,000. Keep in mind that gas leaks are very serious issues, so don’t hesitate to contact a plumber or gas line specialist immediately.

Fixing a gas leak can take anywhere from one to 24 hours, depending on the location and magnitude of the problem. A gas line specialist or gas plumber should be able to give you an estimated time to completion once they evaluate the situation. If your city’s utility company works to fix a gas leak, it will likely have information available about the anticipated time for gas service to be restored.

The cost of repairing a gas leak depends on the type of leak, its severity, and how difficult it is for the repair technician to reach it. Some of the most common gas line repair costs, on average, include:

Cap a gas line: $75–$150
Gas system inspection: $150
Pressure test: $75–$500
Damaged or corroded pipe: $6–$7 per linear foot
Repair gas leak: $120–$5,000

A local natural gas plumber, gas fitter, or gas line specialist should fix gas leaks. Installing gas lines and connections improperly can lead to dangerous gas leaks and explosions. Only a certified plumber or gas line specialist should run gas lines. This is not a job to try out DIY skills, so hire a professional gas plumber or gas line specialist immediately to find the cause of the leak and fix it quickly.
