The cost to repair a gas leak is $120 to $250 on average, but it could be as costly as $5,000, depending on the leak location and severity.

For example, if you have drywall covering the source of the leak, you'll need to hire a contractor to replace the removed drywall. In addition, if the leak is underground, you'll need a contractor to excavate the ground to reach the gas line.

Question 2

What kind of tape do you use for gas lines?

Accepted Answer

•

Only yellow Teflon tape is approved for use on gas lines. Also called yellow PTFE tape, it is thicker and specifically rated for use on natural gas and propane connections. Standard white Teflon tape is not safe for gas applications. If you have questions about sealing gas line connections, contact a pro like a gas line contractor or plumber who installs or runs gas lines.

Question 3

Can you use galvanized pipe for propane and natural gas?

Accepted Answer

•

While some building codes allow galvanized pipe for natural gas, it shouldn’t be used for propane. Propane can cause the pipe to wear down, leading to dangerous leaks. Instead of galvanized piping for propane, you should consider coated copper, black iron, or corrugated stainless steel tubing (CSST). For underground propane line installation, you can use polyethylene (PE).

Question 4

What tubing should I pick for my new natural gas line?

Accepted Answer

•

If you're connecting your gas line to appliances, the pro doing the work may recommend flexible corrugated stainless-steel tubing (CCST). Polyvinyl chloride (PVC) with high-density polyethylene (HDPE) is another relatively inexpensive material commonly used for residential pipes. Ultimately, you'll need to find out what is permitted based on the code requirements in your area.

Question 5

Who should fix a gas leak?

Accepted Answer

•

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.
