As a homeowner, it’s not advisable to make gas line installation a do-it-yourself project, as it requires the proper procedures (and credentials) to ensure that no highly flammable gas leaks occur. You could estimate the cost to install or run a gas line by taking factors like the permit fee for your specific location, whether you’ll be supplying your own gas pipe material and local plumbing rates into account.

Alternatively, a plumber or natural gas specialist can estimate installation costs based on factors such as the type of service line, the length of the gas line, the appliance type, job complexity, whether or not it’s a new gas line and if the old piping needs removing and replacing.

Install gas line for stove cost

You can expect to pay at least $90 to install a gas line for a stove. Some of the cost factors that could affect this price are the amount of piping needed per linear foot, how deep the gas line needs to be buried, the difficulty attached to the project and your local economy. 

Cost to install natural gas line for grill

You can expect to shell out at least $100 to install a natural gas line for a grill. You’d have to include factors such as the cost of the extra line per linear foot, the complexity of the installation and whether you’ve chosen a quick-connect gas line. 

And remember: you cannot use just any grill for a natural gas line, so if your grill cannot run on natural gas, you will need to buy one that does.

Water heater or boiler gas line installation cost

Expect to pay approximately $200 for water heater gas line installation. For a tankless water heater promoting energy efficiency, you’ll need to take factors like the size of the water heater and yearly fuel or operational costs into account.

Cost to add gas line for dryer

You can expect to pay roughly $200 to install a pipe line for your gas dryer. Some cost factors here include whether the lines need to be dug in difficult-to-reach spots and whether the gas line needs indoor or outdoor installing and material.

Fireplace gas line installation cost

You can expect to pay at least $700 to install a fireplace or furnace gas line. Cost factors for this project include the type of gas fireplace you have, the technology used and the size of the fireplace. 

Another factor is whether it’s an existing wood-burning fireplace that needs to be converted via a gas fireplace insert. Installing the insert would cost you more.

Gas line installation cost factors

When a professional estimates the cost to install gas lines in your home, they’ll analyze several factors. Some of the most common factors include:

Gas pipe material 

A homeowner will need to take the various costs of different types of pipe material into account. Materials used are largely dependent on the installation codes for your local jurisdiction and whether it's for indoor or outdoor installation. 

Some of the most common pipes professionals use are corrugated stainless steel (CSST), copper and black iron pipe. 

Gas line location

Homeowners report paying the following for indoor and outdoor gas line installation projects:


Average cost

Supply new gas line to appliance (outdoors)


Supply new gas line to appliance (within the home)


However, minimum costs are low at $120-$150 for some installations.

The type of appliance(s)

Some appliances may need more piping per linear foot and would therefore be more expensive to install. 

Installation difficulty levels may also differ. Gas plumbers and natural gas specialists might charge more for an appliance that requires additional work. For instance, if it's a gas line for a new stove, local contractors may have to remove the kitchen cabinet to run your gas pipe inside the wall. This would make installation more expensive, as it involves extra labor. 

If you’re supplying the materials

Your plumber may charge you more if they have to supply the materials. If you’re knowledgeable on where to source the cheapest material without compromising on the quality, then you may save here. 

Local labor rates 

Local labor rates are primarily dependent on the size of the job and how long it will take to complete the project. Your location also plays a major role in rate differences, as rates vary per state. One of the reasons for this is that material costs may also vary per state. 

Removing and replacing an existing gas line

If a homeowner has an existing line that needs to be removed and replaced with a new gas installation line, they can expect to pay more. The reason being is that this requires more work and an additional disposal cost. Alternatively, installing a new line for a heating appliance requires less labor and would therefore cost less. 

Permits and inspections

Most cities require homeowners to file a permit for a new gas line, and the service provider must get clearance to dig beforehand. Permit fees vary according to location, so research costs in your city.

Reasons you might need to install gas lines

As a homeowner, you may need to install a new gas or natural gas line for several reasons, including:

  • When you’re erecting a new construction or home.
  • You’re working on a home renovation project.
  • You’re removing and replacing corroded, damaged or old gas lines.
  • You’re upgrading your property with gas appliances.

Homeowners may also opt for natural gas line installations because natural gas has energy-efficient qualities compared to coal or petroleum products, according to the U.S. Energy Information Administration.
