How Much Does Gas Line Installation Cost in 2025?

This article was updated using automation technology and thoroughly reviewed for accuracy by HomeAdvisor Editor Ryan Noonan.

Expect to pay an average of $598 to install a natural‑gas line, with most projects averaging between $271 and $937. Some jobs can cost as little as $120 or climb to $2,000. Your final price hinges on the installation method, pipe material, the appliance you’re hooking up, and local labor rates.

Set your budget early—labor rates, materials, and pipe length swing widely by region. Bringing in a licensed natural gas pro keeps the work safe and code‑compliant.

Gas Line Installation Cost Factors

Gas line installation costs depend on a variety of factors, including labor rates and pipe materials.

Pipe Material

Ranging from $1 to $9 per linear foot, pipe materials include pipes themselves, as well as connectors, fittings, and mounting hardware. Together, these components are among the biggest influencers of costs. Larger pipe sizes, required for certain appliances or high-pressure systems, reflect the higher end of material costs—your natural gas contractor can determine the appropriate pipe size for your home to optimize functionality and efficiency.

Each pipe material offers its own mix of durability, flexibility, and installation demands, all of which influence upfront and long‑term costs. For instance, PVC and HDPE are light, affordable, and corrosion‑resistant, but they can still crack if they’re not installed correctly.

Labor

Always hire a licensed natural‑gas plumber for installation or repairs. Master plumbers charge $45 to $200 per hour, though some pros quote a flat project fee.

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 $5 to $12 per linear foot.

• Your plumber might need horizontal directional drilling—a specialized method that snakes lines beneath existing structures—which adds equipment and labor costs.

• Working around tough terrain or cramped spaces takes extra time and raises the overall price.

Project Type

Line extensions sit at the lower end of the price range because they require a short run of smaller pipe. Full replacements land at the upper end: beyond new materials and labor, the crew must safely remove and dispose of the old line.

Permits

Plan for $100 to $300 in permit fees, depending on the regulations where you live. Your gas line installer can advise you and assist with the permitting process.

Landscaping and Foundation Work

Trenching can disturb your landscaping, patio, or foundation. Expect to spend $300 to $10,000 on landscape repairs and $75 to $125 per cubic yard to patch concrete.

New Gas Meter Installation

Your utility company may pick up the tab for a new gas meter. If not, budget $300 to $600. Because most utilities own and service the meter, they often limit installation to their approved contractors.

Gas Line Type

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 20 to 30 linear feet of either 1/2-inch or 3/4-inch pipes, which averages $600. 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 between $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 $20 per linear foot. While gas dryers have higher upfront costs, they’re often more fuel-efficient than electric dryers.

Water Heater

If you're upgrading from an electric to a gas water heater, installing the gas line costs $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.

Furnace

If you’re installing a gas line to your furnace, expect to pay costs of $20 per linear foot.

Gas Line Repair Costs

A sulfur or rotten‑egg smell often signals a leak—call a pro right away. 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. Here are some repair costs to consider:

• 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 are more difficult to find and can cost between $270 and $760.

• 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.

Budgeting for Gas Line Installation

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

• Collect multiple bids from licensed plumbers to compare pricing and scope.

• Bundle other renovation or plumbing work with your gas line project to shave 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.
