How Much Does Gas Line Installation Cost in 2025?

Gas Line Installation Cost Factors

Gas line installation costs depend on several factors, including labor rates and pipe materials.

Pipe Material 

Ranging from $1 to $10 per linear foot, pipe materials include pipes themselves, as well as connectors, fittings, and mounting hardware. Together, these components are one of the biggest influencers on costs. Larger pipe sizes, required for certain appliances or high-pressure systems, typically reflect the higher end of material costs—your contractor can determine the appropriate pipe size for your home to optimize functionality and efficiency. 

Different materials offer varying durability, flexibility, safety features, and installation complexity, which affect upfront cost and long-term performance. For example, both polyvinyl chlorine and high-density polyethylene pipes are affordable, lightweight, and resistant to corrosion and cracks, but they may crack from improper installation. In comparison, black iron carries the highest installation costs, about $15 to $30 per linear foot, but offers airtight fits and high durability.

Line Distance

Certain projects are more extensive than others, and as the length of the gas line increases, so too do material and labor costs. Most gas lines start at your property’s gas meter and end at gas-powered appliances. Adding bends or directional changes to your line adds to its overall length, likewise impacting costs. See these costs for common installations:

• 20 lin. ft.: An existing gas line to the home that requires a branch or extension of tubing for an appliance. This averages $400, ranging from $250 to $500. 

• 20–100 lin. ft.: This distance usually implies the need for a new line to supplement an existing gas supply. These installations cost $200 to $2,000. 

• New line to the street: If the line to your home is already at max capacity or needs replacement, expect to pay $2,000 or more for a new gas line from the main supply to your home, plus costs for interior lines or extensions.

Labor 

Installing or repairing gas lines requires the advanced knowledge and experience of a licensed natural gas plumber. A master plumber costs anywhere between $45 and $200 per hour. Some plumbers use a flat fee pricing structure per job.

Straightforward installations have lower costs, but additional or more complex tasks can drive labor expenses upward. Expect to pay more for installations involving these labor factors:

• Digging trenches for laying gas lines costs $4 to $12 per linear foot.

• Horizontal directional drilling, which requires specialized equipment and labor, may be necessary for gas lines installed under existing structures.

• Navigating difficult terrain or working in tough-to-access spaces.

Additional Gas Line Cost Factors 

Consider these other factors when planning your budget to install or repair a gas line. 

Project Type

The type of project influences the types and amount of materials and the installation complexity. Line extensions are relatively low-cost projects since they generally need a shorter and smaller pipe. Gas line replacements represent the upper end of project costs depending on the extent of damage—in addition to materials and labor installation, replacements also necessitate proper removal and disposal of old materials.

Permits

Most municipalities require homeowners to obtain a permit for installing or modifying gas lines. Permits cost anywhere from $50 to $500. 

Landscaping and Foundation Work

Gas line installation may damage landscaping, foundations, patios, and various other structures on your property. Landscaping services cost $300 to $10,000, depending on the extent of the work. Concrete foundation repairs average $75 per cubic yard or $250 to $20,000 total.

New Gas Meter Installation

Utility companies may cover the cost of a new gas meter—if they don’t, expect to pay between $250 and $500. Because many companies own, install, and maintain the lines and meters, they restrict installation to designated contractors.

• Residential meters: $100–$300. Capable of 250 cubic feet per hour (CFH)*

• Commercial meters: $400–$1,200+. Capable of more than 250 CFH*

• Installation Labor: $150–$400

Cubic feet per hour is a measure of the flow of gas into your home. 1 CFH = 1000 BTUs of natural gas and 2500 BTUs of Propane (LP).

Gas Shut-Off Valve Installation

Gas shut-off valve installation averages $50 to $140 per appliance for materials and labor, with most homeowners paying $300 to $500 for each appliance in their home. Some contractors include valve installation with gas line installation or replacement services. Earthquake shut-off valves feature a safety mechanism that automatically shuts off the flow of gas during a seismic event—labor and materials cost $200 to $600 per appliance.

Gas Line Type

Whether you’re installing new appliances or converting to natural gas, expect to pay $50 to $140 per appliance. Appliances may carry different requirements and restrictions based on type, minimum BTUs, and location.

Kitchen Stove

A kitchen stove gas line costs an average of $20 per linear foot. Most kitchen stove gas lines need about 20 to 30 linear feet of either 1/2-inch or 3/4-inch pipes, which averages $600. Total costs range between $200 to $1,000 or more. Keep in mind that the kitchen layout and installation complexity can more than double the price.

Outdoor Grill or Firepit

Gas-powered grills, firepits, and other outdoor appliances are increasingly popular since they don’t require tank refills. Instead, homeowners pay about $20 to $25 per linear foot to connect gas lines by routing underground, under a deck, or through other areas of your property.

Dryer

Installing a gas line to a dryer costs between $150 and $1,000, or about $20 per linear foot. While gas dryers have higher upfront costs, they’re typically more fuel-efficient than electric dryers.

Water Heater

If you're upgrading from electric to a gas water heater, installation ranges from $750 to $1,400 or $20 per linear foot. Conventional or tankless units may have different piping needs, with high-BTU tankless models sometimes requiring 3/4-inch or 1-inch pipes.

Gas Generator

A standby generator requires a gas line, ranging from $360 to $740. Higher costs generally represent units meant for whole-home power, which may require larger gas lines to accommodate the necessary gas flow and pressure.

Gas Line Repair Costs

Marked by the additive smell of sulfur or rotten eggs, gas leaks pose serious hazards and require immediate professional repair. Gas line repairs vary depending on accessibility, severity, and the type and amount of replacement pipe required. Keep in mind that emergency repairs may come with increased after-hours rates. Review these repair costs:

• A leak at a junction behind a stove is a simple remove-and-replace repair, costing $120 to $250.

• Leaks hidden in walls and crawl spaces take longer to find and can incur additional drywall repair costs, around $300 to $925.

• Buried lines require excavation and landscaping, adding $1,500 to $5,000.

Yearly gas line inspections and preventative checks average $50 to $75. Your plumber or service technician can check the line for rust or leaks, ensure your meter is working correctly, and repair rusted tubing and joints as needed.

Does Installing a Gas Line Increase Home Value?

Installing a gas line doesn’t necessarily translate to a direct increase in home value, but it does offer numerous benefits that appeal to prospective homebuyers. These include:

• Increased energy efficiency

• Lower utility bills

• High-performance appliances

• Flexibility for future gas appliance upgrades

• Reliability during power outages

The value of these benefits may be more pronounced in cases where your existing electric appliances lack efficiency, your electricity rates are relatively high, or gas appliances are generally trending within your local market.

Budgeting for Gas Line Installation

Several strategies can help keep your gas line installation budget-friendly. Try these tips:

• Get several estimates from licensed plumbers or gas technicians to ensure competitive pricing and services.

• Bundle other renovation or plumbing projects together to potentially save on labor costs.

• Consider long-term value—certain materials may cost more upfront, but offer superior durability and longevity.

• Check for utility company offers and rebates for gas line or meter installations.
