Gas leaks are a serious issue that should be handled immediately, so contact a professional as soon as possible. The following guide covers the cost factors involved in gas line repair.
Gas Line Repair Cost Factors
Gas line repair costs range depending on the extent of the damage and the complexity of the repair. Here’s a breakdown of the various issues that can impact natural gas lines and the cost of having them repaired by a pro.
| Project Type | Average Cost Range |
|---|---|
| Repair gas leak | $120–$5,000 |
| Pressure test | $75–$500 |
| Damaged or corroded pipe | $6–$7 per linear foot |
| Cap a gas line | $75–$150 |
| Gas system inspection | $150 |
Cost to Repair a Gas Leak
Gas leaks can be a serious health issue. Fixing a standard gas pipe leak will
cost $120 to $250, though you should plan for financial surprises. For example, if drywall is covering up a leaky gas pipe, you will have to hire a drywall contractor to replace the areas knocked out by the plumber. This will set you back $270 to $760.
If soil is covering the leak, a contractor will need to excavate the ground, and landscaping will be necessary after the job. This will cost $1,500 to $5,000.
If you suspect you have a gas leak, please do not hesitate to contact local authorities. Gas leaks can be hazardous and even fatal.
Cost to Conduct a Pressure Test
If you suspect a gas leak, a plumber will first conduct a pressure test. This is a relatively simple process that should cost $75 to $150 and take around 30 minutes to complete. However, some parts of the country will require a lengthier gas line pressure test that will take more than 24 hours and cost up to $500.
Damaged or Corroded Gas Pipe
Gas pipes corrode over time or become damaged due to an earthquake. If this happens, you may have to have these pipes replaced. In some extreme cases, you may have to replace the entire system. A plumber will charge you the standard gas line installation price plus $6 to $7 per linear foot to remove the damaged piping.
Cost to Cap a Gas Line
Capping a gas line can be necessary if you are ending your gas service and switching to electric or if you want to cap off an unused section of piping to avoid leaks. This process should only take around 30 minutes and should cost you $75 to $150, though certain urban areas will see higher prices.
Cost of a Gas System Inspection
It’s a good idea to have your natural gas system professionally inspected every year. A pro will use this inspection to spot potential problems before they arise. For example, pipes can become weak over time, leading to eventual gas leaks. These plumbing inspections average $150.
Type of Pipe
Gas-powered appliances are popular due to their overall efficiency and quality. If you’ve ever waited impatiently for an electric stove to boil water, you know what we mean.
To experience the benefits of a gas-powered stove or related appliance, you may need to hire a natural gas plumber to run a line from the street to your home. There are multiple types of gas pipes to consider, each with its own use cases and cost per linear foot.
| Type of Pipe | Average Cost Range (Per Linear Foot) |
|---|---|
| Flexible corrugated stainless-steel tubing (CCST) | $2–$4 |
| Polyvinyl chloride (PVC) | $0.50–$1.50 |
| Galvanized steel | $3–$8 |
| Copper or brass | $1–$3 |
Flexible Corrugated Stainless-Steel Tubing (CCST): CCST runs throughout the home from the rigid piping source directly to the appliance. CCST piping costs $2–$4 per linear foot.
Polyvinyl Chloride (PVC) and High-Density Polyethylene (HDPE): PVC and HDPE tend to be found running underground from the street to the home and are great for low-pressure lines. This rigid piping is certainly on the budget-friendly side, at $0.50–$1.50 per linear foot.
Galvanized Steel and Black Iron: High-grade, multipurpose pipes found throughout the exterior and the interior of the home. They perform well for gas pressures of over 500 PSI. Installation tends to be labor-intensive, so count on spending $3–$8 per linear foot.
Copper and Brass: These pipes have long been used for plumbing and related tasks but have fallen out of favor in recent years due to increased regulations regarding their use for transporting gas. Your pro can help you decide what’s best. Copper and brass pipes cost $1–$3 per linear foot.
Repair Method
The repair method your contractor chooses will depend on the type and extent of the damage to the gas line. If the line is rusted, for instance, the contractor may use various methods, like sanding or a rust removal product. Other issues call for welding or pipe replacement. The method will directly impact the cost of gas line repair.
Labor
If you already have a gas line installed and run into an issue, you may need to hire a contractor to conduct repairs. The labor to install or repair gas lines costs between $45 and $200 per hour. Some licensed plumbers charge a set callout fee between $50 and $100. If the contractor charges per hour, the longer the job takes, the more you’ll pay in labor.
Permits and Inspections
Your city or municipality will likely require a permit to start work on a gas line and then an inspection to ensure the work was completed correctly. Permit costs depend on where you live and your area’s requirements, but they average between $50 and $300. You can contact your permitting and inspection department to get an exact cost.
Location
The cost to install or replace a gas line varies with where you live, so talk to a local contractor to get an accurate quote. Installing or repairing a gas line will be more expensive in urban areas due to population density and increased difficulty in excavating piping. Material availability, landscaping needs, and other factors also impact the overall cost. Here are some price estimates for several locations throughout the U.S.
| Location | Cost Range | Average Cost |
|---|---|---|
| Los Angeles, CA | $150–$3,000 | $975 |
| Portland, OR | $175–$1,200 | $625 |
| Minneapolis, MN | $100–$1,150 | $340 |
| Hartford, CT | $150–$1,200 | $475 |
| Chicago, IL | $125–$1,000 | $400 |
| San Francisco, CA | $200–$3,500 | $1,030 |
Additional Repairs or Services
Additional repairs or services can add to the total cost of gas line repair. Here are a few potential repairs or services and their associated costs.
| Repair or Service | Average Cost |
|---|---|
| Install a new gas meter | $300–$600 |
| Gas shut-off valve | $300–$600 |
| Emergency repair | $200–$300 |
Gas Line Repair vs. Replacement
The best way to determine whether to repair or replace a gas line is to consult with your local natural gas plumber as this is not a DIY job. The contractor will be able to assess the damage to the gas line and recommend whether it makes sense to replace or repair it. You can ask for a cost estimate for both scenarios to help you make the final decision. In some cases—if the gas line is old or severely damaged—you may not have a choice and need to replace the line. For minor gas leaks, repairs might be the best and most cost-effective option.
DIY Gas Line Repair vs. Hiring a Pro
Only hire an experienced, licensed, and insured professional to tackle gas line installation, modification, or repairs. This is absolutely not a DIY project. Incorrectly installed gas lines or badly patched leaks are incredibly dangerous and can result in fires, explosions, and even carbon monoxide poisoning.
It's also important to note that most insurance companies won't cover gas-line issues on a self-installed line. Let a local natural gas plumber tackle this project so insurance can cover future repairs or maintenance.
Working with gas can be very dangerous and even harmful to your health. Only attempt gas projects yourself if you have the experience and credentials to do so safely. Otherwise, let the professionals handle these jobs.

Frequently Asked Questions
No, fixing or patching a hole in a gas line may not seal it completely. A patch should be a temporary solution because the damaged area will be weaker than the rest of the pipe, increasing the likelihood of future leaks. Therefore, if a gas line incurs damage, call a licensed plumber and have it replaced right away.
If you suspect a broken gas line in your home, turn the gas off at the mains and call a nearby emergency plumber. Don't attempt to fix it yourself, and don't use anything that could cause a flame or a spark. Your pro has the tools and experience to safely repair the gas line.
It's not hard to replace a gas line, but it requires a pro’s knowledge and expertise. Replacing a gas line becomes more time-consuming and costly if you need to excavate the area to access a gas line underground.
A simple fix or replacing a short run of the gas line inside the home that's easy to access takes an hour or two. However, a more complex repair or one that requires excavation can take several days. Your pro will assess the situation and estimate how long it will take to fix it.
Installing a gas line can be extremely time-consuming and dangerous, so you will want to hire a seasoned professional. Perform a thorough search ahead of time to find a reputable and reliable plumber. Pay special attention to licensing and insurance as you go about choosing the best contractor for your needs.
When hiring a plumber to install or repair gas pipes, consider asking them the following questions:
