How Much Does It Cost to Cap a Gas Line by Type?

You can either cap a gas line in its current location or remove all of the piping material and cap it at the base.

Cost to Cap a Gas Line Without Gas Line Removal

The average cost to cap a gas line without removing the gas line is around $125. Because it only involves putting a cap where the gas line ran to and then a quick seal test, this job only takes around 10 to 20 minutes at most.

Cost to Remove a Gas Line and Then Cap It

Because of the simplicity of this job, there isn’t much related to breaking down the costs.


Labor is pretty much the only fee you’ll need to worry about when it comes to the cost of capping a gas line. When you hire a local plumber, they’ll usually quote you a flat fee for the process once they come out to see how long it’ll take—especially for projects that take less than an hour and require very few materials. 


Speaking of materials, the only one a gas plumber will need is a cap threaded with Teflon tape ($5 to $10) and a few minutes to screw it on. Other required materials include tools like crescent wrenches and possibly a saw to cut a gas line sticking out of the wall too much.


You’ll need to apply for a permit to remove a gas line and cap it completely. Depending on local codes and ordinances, applying for permits will range anywhere from $25 to $100.

Cost to Cap a Gas Line Yourself

8 steps a pro takes to cap a gas line, including cleaning off the pipe threads

Despite sounding easy on paper, dealing with gas is best left to a gas plumber near you. Gas plumbers specialize in the pipes and materials needed to run the fuel source to your home. A standard plumber may not have the necessary skills or experience.

Attempting to cap a gas line yourself is possible (like if you’re going on an extended vacation). Just know, though, that you risk a potential gas leak if the cap is not screwed on correctly. While the cap may appear to be on, there’s a chance you may not thread it correctly, and the gas may continue to come out. The cost to repair a gas leak is around $200.

If capping your gas line will be a permanent solution, we recommend a local and experienced pro do it.

How to Save Money When Capping a Gas Line

One of the easiest ways to save time and money on this process is to give the plumber as much accessibility to the gas line as possible. This may mean decluttering the area, moving appliances, and properly labeling where the gas line is in the garage or basement. It will also help to shut off the gas ahead of time.

Frequently Asked Questions

You may want to remove the gas line if it’s unsightly or if it’s causing a problem with future appliances. The downside is if you decide to go back to gas, you would need to run a new gas line to the area. 

Data from HomeAdvisor says it’ll cost $550 on average to run a new gas line, but the installation can range anywhere from $120 to $1,350.
