If you currently or plan to use natural gas to run your household appliances or heat your home, you need a functional gas line. The gas line starts at the meter outside your home and connects to each appliance that requires gas. A service line extends out to the street from the meter where the main gas line brings the natural gas to your home.

Some small appliances share a gas line, but many larger appliances need their own. Gas lines have varying costs depending on diameter, length, and material. The national average cost ranges from $500 to $2,000, with most homeowners paying around $800 for a 25-foot gas line to a furnace. Costs can be as low as $200 for a 10-foot gas line extension of an existing line. But prices can go as high as $5,000 if your service line needs extending by several hundred feet and requires a new interior line.

Cost to Run a Gas Line

There are many different costs associated with plumbing your home for gas. These are dictated by the area, appliance, length of the line, and installing it. While plumbers run a gas line from your meter to your appliances, the utility company installs the line from the street to your home. These two professionals charge different rates and need to coordinate with one another for the best installation. Even within the home, there are still many different installation types that impact the project.

Gas Line ProjectAverage Cost per Linear Foot
Gas line extension$10 - $20/linear foot
New gas line$15 - $25/ linear foot
Moving gas line$15 - $25/linear foot
Replacing gas line$23 - $35/linear foot
New service line$35 - $60/linear foot


Gas Line Extension Cost

If you have a gas line already in your home and are installing a new small appliance that runs on gas, you may extend an existing line. This is a smaller project than a new line, and because the smaller appliances require less gas, the size of the pipe can be smaller and less costly. That makes the cost of a gas line extension between $10 and $20 a linear foot on average.

New Gas Line Installation Cost

Costs for a new gas line vary depending on the amount of gas the appliance needs to run. For example, a furnace needs more than a hot water heater, so the cost per linear foot is often higher. The material also influences the total cost per linear foot, with $15 to $25 being the average.

Underground Gas Line Installation Cost per Foot

If the new line is being run through your yard to a fire pit or hot tub, you may have additional costs. Some areas have strict regulations on how and where a gas line can run underground, which increases costs. Many of these need to be inspected as well, which may have additional costs. In all cases, trenching needs to happen to open up the ground to lay the pipe. This has a range of costs depending on what it is going under, with $4 to $12 a linear foot being average. The cost to install the line is $20 to $25 a linear foot, and you will have landscaping costs afterward, making the total project range between $25 and $30 a linear foot.

Cost to Move a Gas Line

Sometimes during a renovation or installing a new appliance, you may need to move the appliance and gas line supplying it. This may mean simply replacing the line if it was old, but most of the time, it means disassembling and moving it, which costs between $15 and $25 a linear foot on average.

Gas Line Replacement Cost

If you need to have a line replaced, either because the appliance is moving and the line is too old to move or your current line is leaking or in poor condition, this is usually done for a cost of between $23 and $35 a linear foot. This covers the removal of the old line and installation of the new.

Cost to Run a Gas Line from Street to House

The line that carries gas from the main to your home is your gas service line. It is not installed by your plumber but by your utility company. If your gas meter is 100 linear feet or less from the street, this installation costs nothing, although you are responsible for fixing the landscaping once it is dug up.

If the line is further than 100 feet, then you are responsible for the difference. This costs between $35 and $60 a linear foot on average with the associated trenching and inspections.

Gas Pipe Prices by Type

The plumber who installs your line may have a specific gas pipe that he or she recommends. Other times, you may be able to ask for a specific pipe. Different pipes have varying costs, so if all other things are equal, sometimes opting for a less expensive pipe lowers your project’s cost.

Keep in mind that not all pipe materials are suitable for gas lines. So, while polyvinyl chloride piping is very inexpensive, you do not always have the ultimate pipe choice for this project.

Gas Pipe Prices Chart


Pipe MaterialCost per Linear Foot
High-density polyethylene$1 - $3/linear foot
CSST$2 - $4/linear foot
Copper$2 - $6/linear foot
Galvanized steel$2 - $9/linear foot
Black iron$5 - $10/linear foot


High-Density Polyethylene Piping

For outdoor piping, this material is considered the gold standard by many plumbers. It does not corrode, and it resists punctures and cracks. It is suitable for backyards and can be used in most areas. It costs between $1 and $3 a linear foot on average.

CSST Piping

CSST or flexible corrugated stainless steel tubing, is another very popular material with plumbers. There are many brands of CSST, with each having slightly different attributes and costs. Your plumber may have a brand preference. This is a good material for interior installation because it is faster to install than traditional pipes. It costs $2 - $4 a linear foot on average.

Copper Pipes Cost

Copper is very rarely used with gas and is illegal to use in many areas. Some plumbers refuse to install it for several reasons. Copper is a conductor and, therefore, not always safe to use inside a home with gas. Copper also creates sulfites that clog your gas line. If it is used, it costs between $2 and $6 a linear foot.

Galvanized Steel Piping

Galvanized steel is not as common as the other materials, but it is used for many gas lines. It does not corrode like iron and is not as reactive as copper. It is more expensive at around $2 to $9 a linear foot on average.

Black Iron Piping

This material was used nearly exclusively for gas pipes for many years, and many plumbers still use and install it. It is heavy and durable and does well in a variety of indoor applications. It should not be used below ground due to the risk of corrosion over time. It costs $5 to $10 a linear foot on average.

Total Cost to Run a Gas Line to a House

There are many components to running a gas line to a home, beyond installing the pipe. If you are going from the street in a new installation, several different steps and components need to happen, each with its own cost. Remember that anything up to the meter from the street is the utility company’s responsibility to install. Anything from the meter into the house is the responsibility of your plumber to install. You need to coordinate them both to have a successful installation.

Install meter$0 - $600
Run lines in house$15 - $25/linear foot
Hook up appliances$40 - $100/appliance
Shutoff valves$40 - $100/valve


Run Service Line to House

Your utility company is responsible for running your line from the main to the house. If the distance is 100 feet or less, this costs nothing, but you are responsible for any landscaping afterward. If your home is more than 100 feet from the main, you pay between $35 and $60 a linear foot.

Hook Up to Main

Your utility company also does the main hook up. This is often at no cost, but some companies have fees up to $400. Speak to your utility company about which fees may apply. These fees usually include inspections to ensure the safety of the line.

Install the Meter

Your utility company also installs the meter, which may be provided at no cost. However, depending on the meter and your utility company, labor costs up to $600 to install.

Run Lines in House

At this point, your utility company hands the job off to your plumber. Your plumber is responsible for anything going from your meter to your appliances. This includes the lines you run inside your home or through your yard to outdoor appliances. This costs between $15 and $25 a linear foot per line installed.

Hook up Appliances

Your plumber also connects the appliances. This cost depends on your appliance. Some are easier to install, while others are in locations that make accessing them more difficult for your plumber. There is a cost of between $40 and $100 per appliance for hook up.

Shutoff Valve Installation

Safety valves are very important with any gas installation. You have at least one main shutoff that turns off the gas to every part of your home. Pull this if you ever smell gas or detect a leak. You may also want to have valves installed at all major appliances, such as your furnace and hot water heater. Each valve costs between $40 and $100 to install.

Cost to Run a Gas Line by Appliance

Ultimately, the cost to run a gas line to any appliance in your home is dictated by several factors. This includes the BTUs the appliance requires, location, including how far it is from the meter and how easy it is to access, and the material your plumber uses. Therefore, most appliances have a wide range of costs, and there is a lot of overlap in the cost ranges between appliances. If you have two lines run, you may even get different costs for each line for the above reasons.

Cost to Run a Gas Line

Cost to Run a Gas Line


Appliance LineAverage Cost per Linear Foot
Stove$10 - $15/linear foot
Water heater$10 - $15/linear foot
Dryer$10 - $20/linear foot
Fireplace$10 - $20/linear foot
Garage$10 - $20/linear foot
Grill$10 - $20/linear foot
Fire pit$15 - $25/linear foot
Pool heater$20 - $25/linear foot
Generator$20 - $25/linear foot

Cost to Install a Gas Stove Line

If you have a gas stove in your kitchen, this is one of the easiest lines to run in your home. It is also one of the least expensive because it is easily accessible, does not have a big diameter, and has an easy hook up. It costs $10 - $15 a linear foot.

Water Heater Gas Line Installation

Water heaters use a small but consistent amount of gas all the time. So they may need a slightly bigger line, but not as big as you may need for a fireplace. For this reason, the cost to install a water heater gas line is usually between $10 and $18 a linear foot.

Cost to Run a Gas Line to a Dryer

Your dryer uses more gas at once, but it uses it less frequently than a water heater or HVAC unit. Therefore, it has slightly higher costs to accommodate the thicker diameter pipe. This has a cost of $10 to $20 a linear foot.

Cost to Run Gas Line to a Fireplace

Fireplaces need a more consistent supply and have varying BTU ranges, so they have a wide range of needs regarding the gas line supply size. Expect ranges between $10 and $20 a linear foot for the installation.

Cost to Run a Gas Line to a Garage

It is very common to keep appliances in the garage. It is not the garage that impacts your project’s costs, but the appliances you intend to have installed there. For this reason, this project has a wide range of costs from $10 to $20 a linear foot.

Cost to Install a Natural Gas Line for a Grill

If you grill frequently, it is safer and less expensive to install a line than to keep purchasing and storing small amounts of fuel. This project involves digging, so while the grill does not use much gas, the project’s costs are higher at $15 to $20 a linear foot.

Natural Gas Line for a Fire Pit

Fire pits are also more effective and safer to run if you have a gas line. They use varying amounts of gas depending on their size, which impacts the project’s cost. They are installed below ground, and the cost range is usually between $15 and $25 a linear foot.

Cost to Run a Gas Line to a Pool Heater

Running a line to a pool heater is slightly more complex, so while the heater uses little gas, your overall costs may be higher. This is mostly due to the pool’s proximity and that you need to go beneath the pool deck. Costs are between $20 and $25 a linear foot.

Generator Gas Line Installation

If you have a generator installed, you need to contract with a plumber to run a gas line to the unit at the installation time. This project is not always below ground, but it depends on the generator. It requires specific materials that make costs between $20 and $25 a linear foot.

Cost Factors to Install a Gas Line

Many factors impact the cost of your gas line installation. Whether the line is inside or outside your home affects the material used and the cost. Digging or trenching increases the cost of installation as well as installing lines in hard-to-reach areas.

On the other hand, extending an existing line costs less than installing a new one. So if you have a small appliance, you may be able to T off your existing line to supply it. Specialty plumbers or gas plumbers install gas lines. Plumbers have a wide range of labor rates from $45 to $200 an hour. Depending on your area and the plumber you contract with, this also impacts the project’s cost.​

Gas Line Repair Cost

If your gas line is older, corroding, or having other issues, it is sometimes repairable. This is much cheaper than having a new line installed. The damaged portion is removed for $6 to $7 a linear foot to fix a line. A new line is then installed at the going rate of $10 to $25 a linear foot, depending on location and size. But because repairs are usually done to smaller sections, the project’s overall cost is usually lower than an entirely new line.

Connecting a Propane Line from Tank to House

Propane lines are identical to gas lines, but your plumber handles the entire job in most cases. Sometimes, the utility company that supplies your propane runs the line for you at no cost. If you choose to run the line yourself or the utility company does it, it has the same cost range of $15 - $25 a foot as any other outdoor line.​

Enhancements and Improvement Costs

Gas Line Inspection Cost

Your gas line is usually inspected as part of the installation process. It is usually recommended that you also have it inspected annually to make sure it is working properly. The cost of this is usually between $50 to $75.

Gas Line Pressure Test Cost

If your gas line is leaking, it may not be getting the pressure to do its job. One way to determine this is to have the pressure tested. This has a cost of $75 to $100 on average.

Cost to Cap a Gas Line

If you are disconnecting an appliance from a gas line, it is cheaper to cap the line for potential future use than to remove it. The cost to cap a gas line is around $75 to $150, depending on location and material.

Gas Line Sediment Trap Cost

A sediment trap keeps your line from clogging. They cost around $100 to $150 to have installed.

Landscaping

If you have a service line installed or are installing a gas line in your yard to a fire pit or grill, you have additional landscaping costs. Landscapers charge around $50 to $100 an hour. Your costs are dependent on what you have done.

Gas Stove Installation Cost

If you are switching to gas for the first time, you may want to install a gas stove. This has an installed cost of between $600 and $1,000 on average, depending on the model.

Additional Considerations and Costs

  • Installing a gas line should not be done DIY. Gas is flammable, and if there are loose couplings or the wrong type of pipes used, it could be hazardous. Always use a specialized gas plumber or your utility company to do your installations.
  • You need a permit to install a new gas line. Speak to your town or city hall for more information.
  • Your plumber or the utility company is responsible for calling the 811 “Call Before You Dig” number for clearance. It is best if they get this information first hand, rather than having you relay it to them.
