Cost to Cap a Gas Line With and Without Removal
You can either cap a gas line in its current location or remove all of the piping material and cap it at the base.
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 a pro around 30 minutes to and hour at most.
Your other option is to remove the gas line completely. Removing the gas line and then capping at the base will cost around $250 to complete and will take a pro less than a couple hours. Though this will depend on how long the gas line is.
Capping a Gas Line Cost Breakdown
Because of the simplicity of this job, there isn’t much related to breaking down the costs.
Labor
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.
If you are capping a gas line as part of a remodel, the total labor may also be combined with the cost to install a new gas line.
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.
Permits
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.
Capping a Gas Line Yourself vs. Hiring a Pro
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 on 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, but your pro can also handle this if you are unsure of how.
