Gas Line Installation Costs
New gas line installation from the gas supply and throughout the house typically costs $1,300 to $3,500 with most homeowners spending an average of $2,000, or $20 per linear foot. Costs mainly depend on the number of appliances and the distance from the gas supply.
| Range | Average Cost |
|---|---|
| National Average Cost | $2,008 |
| Minimum Cost | $711 |
| Maximum Cost | $9,540 |
| Average Range | $1,273 – $3,416 |
Natural Gas Installation By Appliances
For a small house that doesn't require outdoor pipes, costs are as little as $711, whereas extremely complex projects with high connection fees, long laying distances, and high-end materials costs up to $9,540.
| Appliances | Average Cost |
|---|---|
| 1 Appliance & Water Heater | $1,273 – $1,676 |
| 3 Appliances & Water Heater | $1,469 – $2,546 |
| 5 Appliances & Water Heater | $1,698 – $3,416 |
A gas line will first need to be run from the street to the house, a meter installed, followed by gas lines installed inside the home from the meter to the new appliances. Costs can vary dramatically based on the complexity of the install, and what size pipe and connections each appliance needs.
For example, digging a trench for the pipe in a straight line is more cost-efficient than Horizontal Directional Drilling (HDD) which is required to create a tunnel to add new lines under a driveway, sidewalk, road, or other obstacles.

Labor Cost To Install Gas Line
The average labor cost to install a gas line is $3 to $11 per linear foot depending on the diameter of the pipe and job complexity. Licensed plumbers charge between $45 to $150 per hour, or $100 an hour on average to place new gas lines.
It's recommended to hire a licensed master plumber to install home gas lines. Many states require a licensed professional because of the risks associated with connecting gas to a home. An apprentice plumber will charge much less, but may only be suitable for minor pipe repairs.
Gas Pipe Installation Material Costs
The average cost of materials for installing or repairing gas lines is $1 to $10 per linear foot, or $4 per foot on average which includes piping, connectors, fittings, and mounting hardware. Pricing depends on the type, diameter, number of turns, and location (interior, exterior, underground).
Different types of pipe include flexible corrugated stainless steel tubing (CCST), polyvinyl chloride (PVC), high-density polyethylene (HDPE), galvanized steel, black iron, and copper.
| Material Type | Cost Per Linear Foot | Uses & Drawbacks | |
|---|---|---|---|
| Most Recommended | |||
| Black Iron | $4.89 | Uses: Interior and exterior use. Stronger than plastic pipe, fits together with compound, and airtight. Drawbacks: Can corrode over time. While it's a strong material, it can crack during an earthquake because it's so rigid. Sealant can deteriorate. No national standards. | |
| Galvanized Steel | $2.19 – $9.33 | Uses: Interior and exterior use, energy efficient, durable Drawbacks: Needs to be welded | |
| Flexible Corrugated Stainless-Steel Tubing (CCST) | $2.00 – $4.00 | Uses: Used in tight areas and locations with a high risk of natural disasters. Flexible and easy to install. Drawbacks: It can crack over time. | |
| Limited Use | |||
| Copper* | $1.03 – $2.64 | Uses: Regions without natural gas. Also made in the form of flexible coils. Drawbacks: Some municipalities won't allow it. Can clog pipes with copper sulfites if soldered wrongly. | |
| High-Density Polyethylene (HDPE) | $0.99 | Uses: Underground exterior lines. Nontoxic, flexible, suitable for high PSI. Drawbacks: Sharp rocks and tree roots can buckle it. | |
| Polyvinyl Chloride (PVC) | $0.22 – $1.55 | Uses: Underground exterior lines. Won't develop pinhole leaks, won't corrode. Drawbacks: Can crack or break during installation. | |
*Copper and brass pipe has strict code requirements because it has an expected life of 20 years.
Underground Gas Line Installation Cost Per Foot
The average cost for underground gas line installation is $12 per linear foot, with prices ranging from $10 to $25 per foot which includes trenching, shaping, backfill, labor, and materials. However, more complicated gas line installations can cost as high as $75 per foot.
Costs vary based on how much work is required. Preparing the site, digging, the trench, and filling the trench can be both time consuming and complicated. Underground gas line installation requires piping that meets specific requirements, and this generally costs more than non-underground projects.
| Task | Cost Per Linear Foot |
|---|---|
| Trenching, Shaping, Backfill | $4 – $12 |
| Labor and Materials | $5.76 – $13.73 |
| Total | $9.76 – $25.73 |
Inspections are required in most states to ensure piping is at the required depth. For example, California has strict regulations regarding underground gas line installation because of earthquakes and other natural disasters. Piping should be at least 18 inches below ground for safer areas and 24 inches for locations at higher risk of external damage.
Black Iron and Galvanized Steel Gas Pipe
Installing black iron gas pipe averages $4.89 per linear foot, while installing galvanized steel averages between $2.19 and $9.33 per linear foot. Both are more labor-intensive than PVC and HDPE piping.
- Black iron pipes are durable, making them ideal for the transportation of both natural and propane gas from the street or the tank to a home. Black iron also has a high heat resistance.
- Galvanized steel pipes are ideal for irrigation and water supply lines, but they are typically not used in new constructions today. It is more likely to be found in older homes built before the 1970s.
PVC and HDPE Piping
PVC piping installation averages between $0.22 and $1.55 per linear foot, compared to the average installation cost of HDPE of $0.99 per linear foot. Both are considered a better alternative than metal pipes for low-pressure gas lines.
- PVC piping can be reliable for 50 years once the initial settling occurs in the first two decades.
- HDPE is more durable and can withstand higher temperatures than PVC. HDPE piping can absorb shockwaves; however, HDPE piping must be about 2.5 times thicker to handle the same pressure as PVC.

Return to Top
Cost Factors To Install or Repair Gas Lines
Several key factors affect the cost of a new gas line. First, understand the basics of your existing configuration before you get started—from your current appliances and your home's existing gas lines to adding a new line to the type of gas you use.
Additional Cost Factors
- Required permits tend to range from $50 to $300.
- Annual gas system inspections cost $100 to $150 per inspection on average.
- Trenching costs between $4 and $12 per linear foot depending on the depth. The service provider must get a permit before trenching.
- Complex installations and repairs will increase the amount of time and costs to complete the project.
- Landscaping costs to make repairs from trenching range from $500 to $2,000 or more depending on the landscaping setup you have. Replace sod will be much cheaper than running a line under a patio.
- Typical concrete prices average $125 per cubic yard.
Accounting for Gas Appliances
Go through your home and determine how many gas appliances you have. Pricing changes based on pipe size, which is determined by how many BTUs all of your appliances are using.
- Create a list of all of your gas appliances.
- Read the table or nameplate of each appliance and record the gas input.
- Check the gas meter (natural gas) for the ID size.
Gas Type – Propane or Natural Gas
The cost is roughly the same for installing a propane gas line from the tank to the house as the cost to have natural gas run to the house. Find out which kind of gas your home currently has.
- Propane gas is stored in tanks, usually outside the home.
- Natural gas lines are comparable to power bills in that a local or city utility company provides the service. Instead of a tank, there will be a meter outside your home.
If you are building a new home or do not currently have gas, there are several benefits to each type. Take the time to understand the differences between propane and natural gas so that you can choose the right one for your individual needs.
Gas Line Pipe Size
The amount of piping currently in your home and the size of the tubing is the final determining factor in your total costs. If the existing gas line has the capacity to add a new gas appliance, the prices will be significantly lower than a new install. If a system is already at capacity, a new line will need to be installed to the gas manifold.
Determining gas pipe sizing in your home is a complicated process; it's best to let a professional complete the calculations to ensure the right approach is adopted.
