Cost to Run a Gas Line by Project

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

Project	Average Price per Linear Foot (Labor Included)
Extension	$11 – $22
New Installation	$11 – $28
Relocation	$16 – $28
Replacement	$25 – $38

Gas Line Extension Cost

If you already have gas piping in your house and want to install new small appliances, you may extend an existing gas line. You can expect to pay for this work between $11 and $22 per linear foot for materials and labor when having your gas line extended. Extensions cost less than a new gas installation because the overall size of the pipe will be smaller in length. A smaller appliance will not need a large line connecting to it. Therefore, a smaller gas pipe means less in materials and installation costs.

New Gas Line Installation Cost

It will cost anywhere from $11 to $28 to have a new line installed when you include the cost of materials and labor. Whether you need to pay on the high or the low end depends on the size of the appliance the new line is being installed for and how much fuel will need to be delivered to it. The most expensive projects and the largest ones for new pipe installation are furnaces, which require a significant amount of delivery. These gas lines run from $22 to $28 per linear foot. Projects like water heaters will be less expensive as a smaller line is needed for operation and can run between $11 and $20 per linear foot.

Cost to Move a Gas Line

Moving a gas pipe is a project that will run homeowners between $16 to $28 a linear foot, including the costs of gas line installation. This is most commonly done during house remodeling projects. If during the redesign process one or more appliances need to be moved, the gas line supplying them may need to be moved as well. You also may find the need to move a line when changing from electric to gas appliances. For example, if you previously had a gas stove and changed to an electric one, the gas pipe may need to be moved so that the sliding safety feature on new electric models can be engaged. Often with stoves, the lines were behind the stove, which gets in the way when a gas line installing an electric one.

Gas Line Replacement Cost

You may also run into a situation where you need a gas pipe replaced. This project will cost you anywhere between $25 and $38 per linear foot. The primary reason for the higher cost is that the old line requires removal and disposal. There are a few reasons you may want to have your line replaced. One reason is gas leaking. A leaking pipe can be extremely dangerous and should be replaced immediately. Another reason is the pipe may be found in poor condition when you attempt to have it moved. In this case, a replacement would be needed.

Gas Line Installation Cost Breakdown

There are many components to running a gas line in a house beyond installing the gas pipe. If you are going from the street in a new gas pipe installation, several different steps and components need to happen, each with its own price. Remember that anything up to meter¹ 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 gas pipe installation. Below you can see the average prices for connecting an extra 50 feet of line to the main gas line and installing three to four appliances, with new gas lines in three rooms in a 2,000 sq. ft. home.

Project	Average Range (Installed)
Run Line From Main to House	$0 – $1,200
Hook Up to Main	$0 – $400
Install Meter	$0 – $600
Run Lines in House	$1,300 – $1,700
Hook Up Appliances	$300 – $450
Shut-Off Valves	$250 – $600

Cost to Run a Gas Line to a House

The line that carries the fuel from the main to your house is your service line. If your gas line project requires an extra 50 feet to connect the house to the main, you can pay $950 to $1,200 on average for the project. It is not installed by your plumber but by your utility company. If you run a gas pipe from the street to the house and the meter is 100 linear feet or less from the street, this gas installation is free. However, 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.

Cost of Connecting to a Gas Main

When running a gas pipe from the street to the house, the main will need to be hooked up. For the above project, you need to pay anywhere from $250 to $400 on average.

Your utility company also does the main hook up, in some cases, may do it free of charge, depending on the area you live in and the service company providing natural gas. Speak to your utility company about which fees may apply. The fee to connect the line to the main almost always includes the price of the inspection, which is critical to ensure safety.

Gas Meter Installation Cost

Your utility company also installs the gas meter, which may be provided for free. However, it will range an average of $300 to $600 if the utility company you use does not include the service. When the utility company comes to install the gas meter, they start by finding the ideal location. A gas meter cannot be by gas outlets or fireplace valves for safety reasons and must have an area at least three feet in front of it that is clear. If the area around your house has trees or a brush, you may need to do some trimming before the meter can be installed.

Cost to Hook Up Appliances

If you need to have three to four appliances hooked up to your project, you need to pay around $300 to $450 for the gas installation project. The most common gas appliances installed in houses are furnaces and water heaters. Homeowners often choose a dryer or stove that runs on this fuel too. Your plumber also connects the appliances. This cost depends on your appliance. Some appliances are easier to install, while others are in locations that make accessing them more difficult for your plumber.

Cost to Install Gas Lines in a House

You need to pay between $1,300 and $1,700 to run the lines in your house to three rooms and approximately three to four appliances. Most often, gas lines will be run to laundry areas, kitchens, and utility rooms, since these are the most common areas where appliances can be found. When it comes time for this part of the project, the gas installations will be handed off to a plumber. The plumber is responsible for anything going from your meter to your appliances. This includes the gas lines you run inside your home or through your yard to outdoor appliances.

Gas Shut-Off Valve Installation Cost

Each appliance that uses gas in your kitchen needs a shut-off valve. For shut-offs for three to four appliances in your home, you need to pay an average of $250 to $600 for the complete gas installation project. Safety valves are very important with any gas installation. You need to pull these if you ever smell like fuel or detect a leak. When shut-off valves are installed, an inspection will be included in the price to ensure everything is operating safely before the plumber leaves.

Gas Line Installation Cost by Number of Appliances

When you run a new gas line for your house, it is typically for more than a single new kitchen appliance. While you can run a short extension off of an existing gas line to fuel a new stove or fireplace, in many instances, you will have a few appliances to warrant an entirely new gas line.

The most common combinations include 1 to 5 gas appliances combined with a water heater. This can be an oven and water heater, an oven with a separate stovetop, a water heater and a fireplace, or any other combination of appliances. The more gas appliances and the farther away they are spaced from one another and the main line, the higher your total costs of the project. For example, having your water heater directly off the kitchen where the oven is installed will be a cheaper installation than having the water heater and the oven on separate floors of the home.

Below are the average costs for installing a new gas line by the number of appliances.

Appliances	Average Cost (Installed)
1 Appliance & Water Heater	$1,350 – $1,800
3 Appliances & Water Heater	$1,600 – $2,700
5 Appliances & Water Heater	$1,750 – $3,700

Gas Pipe Costs by Material

The material that makes up your gas line installation can be many things. Many plumbers work specifically with certain gas pipe materials, while others have a range of different gas pipes that they utilize for projects. Not all pipes that gas plumber works with will be suitable for gas lines. For example, PVC is inexpensive and good for carrying water, but it will not work for gas.

There are essentially five types of gas pipe material that may be used. Some like high-density polyethylene² are inexpensive and very common. Others like copper and black iron were once used extensively, but they have fallen out of favor due to high costs and availability.

Generally, the gas pipe type used plays a role in the project cost, how long it lasts, and how it performs. Below are the average costs per linear foot for the most common gas pipe materials.

Material	Average Cost per Linear Foot (Materials Only)	Average Cost per Linear Foot (Installed)
High-Density Polyethylene	$3 – $5	$12 – $18
CSST	$3 – $6	$13 – $23
Copper	$4 – $8	$12 – $23
Galvanized Steel	$3 – $11	$13 – $26
Black Iron	$7 – $13	$17 – $33

High-Density Polyethylene Pipes Cost

One of the most popular options for outdoor gas piping is high-density polyethylene pipes which will cost an average of $3 to $5 per linear foot for materials only. For outdoor gas piping, this material is considered the gold standard by many gas plumbers. It does not corrode and resists punctures and cracks. It also is designed to withstand higher levels of PSI. It is suitable for backyards and can be used in most areas. The main drawbacks are that it can buckle when it encounters sharp rocks or tree roots. This material can also be used for indoor gas piping.

Copper Pipes Costs

A rare material used for this type of gas installation project is copper. The material cost of the copper lines is between $4 and $8 on average. Copper is very rarely used with this type of fuel and is illegal to use in many areas, primarily because the gas material is soft and can become easily damaged, leading to safety issues. 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 line. Copper lines can be rigid or flexible. Before having a copper gas pipe installed, you need to check with the municipality before starting the job. Though copper is rarely used, it once was popular for indoor and outdoor gas installation.

CSST Piping

CSST gas piping, also known as flexible corrugated stainless steel tubing, is another popular option that will cost anywhere from $3 to $6 per linear foot on average. There are many brands of CSST, with each having slightly different attributes and costs. Your gas plumber may have a brand preference. This is a good material for interior installation because it is faster to install than traditional gas pipes. It can also be used in tighter spaces and installed in areas with higher instances of natural disasters. The main drawback of this type of material is that it can crack over time. CSST piping is great for both indoor and outdoor use, even in areas with seismic activity.

Black Iron Gas Pipe

One of the most expensive and predominantly used gas materials in past years is black iron. The materials for a black iron gas pipe run from $7 to $13 per linear foot. Even though its popularity is slightly declining, many plumbers still prefer this material for new installs and replacement lines. It is extremely strong and durable and is fastened together with a compound that produces an airtight fit. While it can be used for interior and exterior applications, it is not recommended for outdoor use because it corrodes over time, and the sealant wears down when underground.

Gas Line Installation Cost by Location

There are several locations in the house where you may need to have a gas line run. Different rooms in the house likely require different appliances. For example, the cost is the most common kitchen appliance that uses a gas line. In the bathroom, it tends to be the dryer. For bedrooms and living rooms, the most common reason to need a gas line installed is for a fireplace. Garages often have water heaters and generators, but they may also have dryers if there is no dedicated laundry room and the appliances are not located in the bathroom.

The size and BTU of each appliance can impact the cost of the gas pipe being run. For this reason, it is not necessarily the location that is the biggest driving factor behind the costs, but rather what is installed in each location. Below you will see the rooms where you most likely need a line run and how much per linear foot you can expect to pay, including materials and labor.

Location	Average Price per Linear Foot (Installed)
Kitchen	$12 – $18
Bathroom	$12 – $23
Bedroom	$13 – $22
Living Room	$12 – $24
Garage	$12 – $28

Cost to Extend a Gas Line by Appliance

When running a gas line installation inside the house, you are essentially installing it by appliance or extending it from the meter to the appliance. The project cost is generally dictated by what that appliance is, how many BTUs it requires, and where it is located. Access and gas material preferences by gas plumbers also play a role, but ultimately, it is the appliance itself that will have the biggest part in your final costs. Therefore, most appliances have a wide range of prices. There is a lot of overlap in the cost ranges between appliances. If you have two lines running, you may even get different costs for each line for the above reasons.

Appliance	Average Price per Linear Foot (Installed)
Stove	$12 – $18
Water Heater	$13 – $18
Dryer	$13 – $23
Fireplace	$12 – $23
Grill	$12 – $23
Fire Pit	$13 – $28
Pool Heater	$22 – $28
Generator	$22 – $28
