Gas Line Installation Cost: $272 to $936 (HomeAdvisor 2026)

Gas line installation cost at a glance. Three cost guides, shown side by side and not averaged.

When to call: a gas smell is an emergency, a new line is not

• Call now, from outside: you smell rotten eggs or hear hissing near a line or appliance. The Kansas Corporation Commission says to leave immediately, not to use light switches, phones or garage door openers on the way out, and not to look for the leak or shut valves. Call the gas utility or 911 once you are away from the house. The California PUC adds: leave on foot and do not ring doorbells to warn neighbors.
• This week: you bought a gas appliance and need it hooked up, or a remodel opened the wall where the new line will run.
• Can wait: planning a range swap, an outdoor kitchen or a standby generator. Get two or three written prices and ask each about the permit.

A leak on an existing line is a different job with its own prices; see gas line repair cost and leak signs, and for smells you cannot place, gas smell in the house.

How much to run a gas line for a stove?

The stove is the most common reason people call about a new gas line. HomeAdvisor's June 2026 guide prices a kitchen stove line at about $20 a foot and says a typical run of 20 to 30 feet averages $600. HomeGuide's January 2026 guide puts the whole stove or range hookup at $500 to $1,200, and says a stove usually needs 20 to 30 feet of 1/2-inch or 3/4-inch pipe from the nearest gas source. Fixr's per-foot figure for a stove line is lower, $10 to $15.

What moves a stove line up the range is the route. A kitchen over an open basement is the easy case: the plumber drills up through the floor behind the range. A slab house, a finished basement ceiling or a second-floor kitchen means opening walls or ceilings, and drywall repair is usually a separate bill. If your house has no gas service at all, the stove line is the small part of the job; see the utility section below.

Gas line installation cost per foot by pipe material

Material only, per linear foot. HomeGuide January 2026; HomeAdvisor June 2026. Installed prices run $15 to $30 a foot (HomeAdvisor) or $15 to $50 or more (HomeGuide).

The material is a small share of the price. Labor is most of it: HomeGuide lists plumbers and gas fitters at $50 to $200 an hour and HomeAdvisor lists master plumbers at $45 to $200. HomeGuide says simple, easy-access runs cost $15 to $25 a foot installed. The plumber picks the material by what your local code allows, where the pipe runs and how much gas the appliances need. HomeGuide notes that tankless water heaters may need larger pipe because of their higher BTU demand, which raises cost.

If the plan uses CSST, the yellow-jacketed flexible tubing, HomeGuide says it requires special bonding and grounding to prevent lightning damage. Ask who does the bonding and whether it is in the price.

Gas line cost by appliance: dryer, generator, fireplace, grill and more

National figures for the gas piping only, not the appliance. Not listed means that guide did not price it.

The appliance can cost more than the pipe. HomeGuide says a complete whole-house natural gas generator runs $6,000 to $11,000 or more, against $400 to $1,500 or more for the gas line alone; the rest of that job is on whole house generator cost. For a pool heater, HomeGuide puts the heater and line together at $1,500 to $4,500 or more. Swapping an electric water heater for gas adds the line to the price on water heater replacement cost; HomeAdvisor prices that line at about $20 a foot. Furnace swaps are on furnace replacement cost.

Outdoor gas lines: trenching for grills, fire pits and generators

Lines to a grill, fire pit, pool heater or generator usually run underground. HomeAdvisor puts trenching at $5 to $12 a linear foot, and $20 to $25 a foot for outdoor grill and fire pit lines, which it says are routed underground, under a deck or through other parts of the property. HomeGuide says polyethylene pipe is often preferred underground because it resists corrosion. The ground has to be put back too: HomeAdvisor lists landscape repair at $300 to $10,000 and concrete patching at $75 to $125 a cubic yard.

Before anyone digs, call 811 to have buried utility lines marked; the California PUC directs people to do this before a project. Some areas also want a separate excavation permit, HomeGuide says.

Natural gas or propane: what changes the price

Natural gas comes from the utility main, so there is no tank. Propane needs a storage tank on the property. HomeGuide puts an above-ground propane tank at $300 to $3,000 or more installed and a buried tank at $1,500 to $5,000 or more, and says some propane companies install the tank and basic connection at no charge when you sign up, though you may still pay a plumber for the piping inside. Ask the propane supplier what it sets and connects before you price the indoor work.

No gas service yet? The utility, the meter and the main

A home with no gas service needs a line from the street before anything else. HomeGuide puts a new service line from the street at $2,000 to $10,000 or more, depending on distance and ground, and says some utilities cover running a new line up to a set footage when you start service. Ask your gas utility about that allowance first, since it can change the total more than any choice inside the house.

The meter belongs to the utility in most places. HomeAdvisor says to budget $300 to $600 for a new meter if the utility does not cover it, and that utilities often limit meter work to their approved contractors. HomeGuide prices moving a meter at $1,000 to $4,500. Converting a whole house from oil heat to gas is a bigger project: HomeGuide puts it at $6,000 to $12,000 with an existing gas line and $12,000 to $20,000 or more with a new one.

Gas line permit and pressure test: what happens at inspection

Expect a permit. HomeGuide puts gas line permits at $100 to $300 or more, Fixr at $50 to $300, and HomeAdvisor says most cities require a licensed pro before they issue one. The contractor usually schedules the inspection, HomeGuide says, and it may include a pressure test to check for leaks. HomeGuide prices a standard test at $75 to $150 and extended 12 or 24 hour tests at up to $500. In Dallas, for example, a city inspector witnesses a 3 psig test held for 15 minutes before releasing the service to the utility.

Who can install a gas line? State licensing varies

There is no single national rule. Each state, and often each city, decides who may do gas piping, so check yours before you hire. Two examples show how different the answers are:

• Massachusetts licenses gas fitters separately from plumbers. Its Division of Occupational Licensure says any licensed master or journeyman plumber may do gas fitting work, but a gas fitter may not do plumbing. Journeyman gas fitters must have worked at least two years as apprentices. The state's consumer fact sheet says to verify a license with the Board of State Examiners of Plumbers and Gas Fitters.
• Texas covers gas piping under its plumbing license law: Occupations Code 1301.002 defines plumbing to include piping used to supply or distribute "water, other liquid, or gas". Section 1301.051 says a property owner does not need a license to do plumbing in their own homestead. That is a license exemption only; cities still set permit rules, and Dallas, for one, requires a permit and an inspector-witnessed gas test.

Even where an owner may legally do the work, the cost guides advise against it. HomeGuide says "Never attempt DIY gas line installation!" because mistakes can cause leaks, fires or explosions, and HomeAdvisor says to always hire a licensed natural gas plumber. Ask any company for its license number and check it with your state board.

How long does gas line installation take?

HomeGuide says a simple extension may take 2 to 4 hours, while complex jobs can take 8 to 16 hours or more, sometimes over several days. Add time for the permit and for the inspector's visit before the gas is turned on. If the utility has to set a meter or run a new service line, its schedule usually sets the pace.

Gas appliance safety once the new line is in

A new gas appliance means a new source of carbon monoxide. The CPSC says to install battery-operated CO alarms, or alarms with battery backup, "on every level of the home and outside sleeping areas", and that most appliances should be installed by qualified professionals. It also says never to use gas ranges, ovens or clothes dryers to heat a home, and to keep appliance vents and chimneys clear of tarps and debris during renovations. The CPSC puts deaths from carbon monoxide from non-automotive consumer products at about 170 a year in the U.S. If an alarm sounds, see carbon monoxide alarm going off.

Questions to ask before you book gas line installation

• Is the price per foot or a flat price for the whole run, and does it include opening and patching walls?
• Which pipe will you use, and if it is CSST, is bonding included?
• Does the price include the permit, the pressure test and the inspection visit?
• Who calls the utility to shut off and restore gas, and who relights the other appliances?
• Is the line sized for every gas appliance I might add later, such as a tankless water heater?
• What is your license number, and can you send proof of insurance before work starts?

Calls go to an independent company that serves your area and takes this kind of job; hours vary. How calls work. Other plumbing work and prices are on the plumbing hub.

What to do now: before you call about a new gas line

1. If you smell gas at any point, stop. Leave the house and call the gas utility or 911 from outside.
2. List every gas appliance you want on the line now or later, so the pipe can be sized once.
3. Measure roughly how far each appliance sits from the gas meter or the nearest gas pipe.
4. No gas service yet? Call the gas utility first and ask what it covers for a new service line and meter.
5. For any outdoor run, call 811 to have buried lines marked before digging starts.
6. Ask each company about the permit, the pressure test and its license number, and get the price in writing.
7. Put CO alarms on every level and outside sleeping areas before the new appliance is lit, as the CPSC advises.
