Gas Line Installation Cost in 2026: Stove, Dryer & More

For nine days last winter, a brand new gas range sat in the middle of our dining room with the plastic still on the knobs. We ate takeout around it. The delivery guys had taken one look at the wall behind the old electric stove and said, politely, “No gas here, ma’am.” They were right. I had bought the stove before I bought the pipe.

That’s the most expensive order to do things in.

The gas line installation cost in 2026, short version: running a new line to one appliance usually costs about $300 to $1,500 when there’s already gas in the house and the run is short. Longer runs, a generator outside or a line to a detached garage often land between $1,500 and $4,000. Plumbers I talked to priced the pipe itself at roughly $15 to $30 per foot installed, before permits and extras.

Below: prices by foot and by appliance, my three written quotes for the kitchen line, the permit and pressure test nobody mentioned up front, and why this is one job I won’t touch myself.

Gas line installation cost in 2026

A gas line quote has a few moving parts, and the pipe is the smallest one. You’re paying for a licensed plumber or gas fitter’s time, a permit, a pressure test, a shutoff valve at the appliance, and the connector that runs from that valve to the appliance itself.

The ranges below come from my three quotes, a fourth quote a neighbor got for her generator, and what the plumbers told me when I asked them to walk me through their numbers:

Short run (under 20 feet) from an existing line to a stove or dryer: about $300 to $900.
Medium run (20 to 50 feet) through a basement or crawl space: about $700 to $2,000.
Line to an outdoor appliance, generator or detached building: about $1,500 to $4,000 or more, mostly because of trenching.
Bringing new gas service from the street to a house that has none: that’s usually the utility’s job and their price, often $0 to $3,000 depending on the company and distance.

What moved my price most was the distance to the nearest gas pipe. Ours was 26 feet away, at the furnace and water heater in the basement. If your kitchen sits right above the basement manifold, you’re looking at the low end. If the plumber has to cross the whole house or open finished ceilings, it climbs fast.

Gas line installation cost per foot: black iron, CSST or poly

The pipe type changes the labor more than the material. What I heard from three plumbers, and what I could check on the shelf:

Black iron (steel) pipe: the old standard. Cheap material, slow labor because every piece is cut, threaded and fitted. Installed runs priced at roughly $20 to $30 per foot in my quotes.
CSST, the yellow-coated flexible tubing: pricier material, much faster to run through joists, so it often comes out cheaper overall, roughly $15 to $25 per foot installed. It has to be bonded to the home’s electrical grounding according to the manufacturer’s instructions, which matters in lightning-prone areas.
Polyethylene (yellow plastic) pipe: for underground runs only, buried at the depth your local code requires, with a riser where it comes above ground. The pipe is cheap. The trench is not.

Quote one wanted black iron for the whole run and charged for it. Quote three used CSST through the joists and black iron at the exposed sections near the furnace. Both are normal choices. What I cared about was the bonding, and only one of the CSST quotes mentioned it without me asking.

Gas line installation cost by appliance

Every appliance needs a different amount of gas, measured in BTUs. A plumber adds up everything on the line (furnace, water heater, range, dryer) to size the pipe so nothing starves when it all runs at once. That math is why a “simple” new line sometimes means upsizing an old one.

Rough installed ranges per appliance, assuming gas is already in the house:

Gas range or cooktop: about $300 to $1,500. Don’t forget the outlet. Gas ranges still need a regular 120-volt plug for the igniter and clock. Our old electric range used a 240-volt outlet, so an electrician changed it for $180.
Gas dryer: about $250 to $1,000, usually on the low end if the laundry is near the water heater.
Gas fireplace or insert: about $300 to $1,500 for the line, separate from the unit and venting. If you’re converting a wood fireplace, the chimney may need work first. My guide to chimney liner costs covers that part.
Standby generator: about $500 to $3,000 for the gas line alone, sometimes more if the meter needs upgrading. The full project is in my breakdown of whole-house generator installation cost.
Furnace, boiler or water heater swapped from electric or oil to gas: the line is often folded into the bigger quote. See what a furnace replacement costs for how that bundle usually looks.
Outdoor grill, fire pit or patio heater: about $500 to $2,500, almost all of it trench.

What gas line installation cost me: three quotes for one stove

The job: a new line from the basement manifold near the furnace, 26 feet through the joists, up through the floor behind the stove, ending at a shutoff valve and a flexible connector. Permit and inspection included or not, depending on who you ask.

Quote one, $1,450. A big plumbing company. Black iron the whole way, permit included, but the quote said “connector by others.” When I asked who “others” were, he said the appliance store. The appliance store had already told me they don’t do gas connections in our county.

Quote two, $780. A handyman my coworker swore by. CSST, done in an afternoon. No permit (“it’s just a stove”) and no mention of bonding or a pressure test. He wasn’t licensed for gas, which in our state means he shouldn’t have been doing it at all. That price got a lot less exciting once I looked that up.

Quote three, $1,150. A licensed plumber, small shop. CSST with bonding, black iron at the manifold, new shutoff valve behind the range, new connector, permit pulled by him, pressure test before the inspector came, and he hooked up the range once it passed. Written, line by line, with the permit fee ($95) listed separately.

I took quote three. Add the $180 outlet swap and the total for a gas stove I’d already paid for came to $1,330. If I’d checked the wall before I clicked “buy,” I would have budgeted for it instead of eating takeout next to a crated range for nine days.

Permits and hidden gas line installation costs

The extras that showed up, or should have:

Permit: in my area $95. I’ve heard $50 to $300 elsewhere. Most towns require one for any new gas piping, and the inspector checks the pressure test.
Pressure test: usually included by a licensed plumber, sometimes listed at $75 to $200. If a quote doesn’t mention it, ask.
Drywall and ceiling repair: if the run crosses a finished ceiling, someone has to open it and close it. Our basement ceiling is open joists, so nothing there. In a finished basement, budget a few hundred dollars for patching.
Meter or regulator upgrade: adding a big appliance like a generator or tankless water heater can push you past what the meter handles. The utility decides, and the price is theirs.
Electrical: the 120-volt outlet for a gas range, or a separate circuit for some appliances.

One more. If the plumber finds an old leak or corroded fitting elsewhere on the system while testing, it has to be fixed before the new line passes. Our test came back clean. My neighbor’s didn’t, and her generator line grew by $340 for a rusty union near the meter.

Outdoor and underground gas line installation

Underground runs cost more because someone has to dig. Trenching for gas often prices at roughly $10 to $25 per foot on top of the pipe, more for rocky soil, tree roots or cutting through a patio.

Before anyone digs, the utility lines have to be marked. The national 811 before-you-dig guide says to call 811 a few business days ahead and points out that some lines sit only a few inches deep. A good contractor makes that call. Ask whether yours did.

My neighbor’s generator line ran 38 feet from the meter, mostly under lawn. Her quote: $2,600 including trench, poly pipe, riser, permit and test, plus the $340 fitting surprise. The generator itself was a different, much bigger number.

Why gas line installation isn’t a DIY job for me

I’ll paint, tile, patch drywall and swap a faucet. Gas lines are where I stop. A tiny leak at a fitting you tightened yourself can fill a room, and a bad connection on an appliance can feed carbon monoxide into the house. In many states, homeowners aren’t allowed to do gas work without a permit and inspection anyway, and insurance companies care a lot about who did it.

The CPSC’s carbon monoxide information center says more than 200 people in the U.S. die each year from accidental non-fire CO poisoning linked to consumer products, and recommends battery or battery-backup CO alarms on every level of the home and outside sleeping areas. When the range went in, I bought a second alarm for the hallway outside the bedrooms. It was $32.

What you can do yourself: pick the appliance after you know where the gas is, clear the path for the plumber, call to get the permit question answered, and handle the outlet with an electrician. For how a gas stove fits into a bigger kitchen project, my kitchen remodel cost guide has the rest.

If you ever smell gas, leave the house first and call the gas company from outside. Don’t flip switches on the way out.

Ask every plumber these before you sign. Are you licensed for gas work in this state. Black iron, CSST or both, and if CSST, is bonding included. Is the shutoff valve and the appliance connector included, and will you hook up the appliance. Who pulls the permit and what does it cost. Is a pressure test included. Did you check that the existing pipe and meter can handle the new load. Will you open any finished walls or ceilings, and who repairs them. If it’s underground, who calls 811. What is the warranty on the labor. Get every answer in writing.

Gas line installation cost by job

I built this from my quotes, my neighbor’s generator quote and what three plumbers told me. Use it to check a quote against. Your local prices will be different.

Gas line job	Typical run	Installed cost (2026 estimate)	What pushes it higher
Hook up a new appliance to an existing stub	0 – 3 ft	$150 – $400	New shutoff valve, old connector
Gas range or cooktop, new line	10 – 30 ft	$300 – $1,500	Finished ceilings, outlet change
Gas dryer, new line	5 – 25 ft	$250 – $1,000	Laundry far from the manifold
Gas fireplace or insert line	15 – 40 ft	$300 – $1,500	Chimney or venting work
Outdoor grill or fire pit, underground	15 – 50 ft	$500 – $2,500	Trenching under patio or roots
Standby generator line	10 – 60 ft	$500 – $3,000+	Meter upgrade, long trench
Detached garage or workshop heater	40 – 150 ft	$1,500 – $4,000+	Long trench, larger pipe size
New gas service from the street	varies	$0 – $3,000+ (utility)	Distance, road crossing

Estimated 2026 ranges for licensed installation including pipe, valve, connector and pressure test. Permits, trenching and meter work vary by region and utility.

What blows the gas line budget

Buying the appliance before checking the gas. My range sat crated for nine days and I paid for an outlet change I hadn’t planned. Ask a plumber where your nearest pipe is first.
A cheap quote with no permit, no test and no license. $370 less than my final pick, and the risk was all mine: a failed inspection later, an insurance question, or a leak.
Undersized old pipe or meter. Adding a generator or tankless water heater can mean upsizing pipe or a meter swap. My neighbor’s $340 fitting was the small version of this.

For how a gas line fits next to bigger projects, our overview of home renovation costs has the rest of the numbers.

The inspector came on a Tuesday, read the gauge, signed the tag and left in eleven minutes. The plumber hooked up the range that afternoon. The first thing I cooked on it was grilled cheese, because after nine days of takeout that’s what everyone voted for. The plastic is off the knobs now.

Frequently Asked Questions

How much does it cost to run a gas line for a stove?
If gas is already in the house, running a new line to a stove usually costs about $300 to $1,500 in 2026, including the shutoff valve, connector and pressure test. Long runs or finished ceilings push it higher, and you may also need a 120-volt outlet for the range. These are estimates and vary by region.

How much does gas line installation cost per foot?
Roughly $15 to $30 per foot installed inside the house, depending on whether the plumber uses CSST or black iron pipe. Underground runs add trenching, often $10 to $25 per foot. Permits, testing and the appliance hookup are usually extra lines.

Can I install a gas line myself?
Many states and towns require a licensed professional and a permit for new gas piping, and a leak can cause a fire or carbon monoxide problem. I hire this out every time. What you can do is plan the appliance location, get the permit question answered, and install CO alarms on every level.

All prices here are 2026 estimates from my own written quotes and what plumbers told me, and they vary by region, pipe type, run length, utility and local code. Tessa is a hands-on homeowner, not a licensed plumber or gas fitter. Gas piping should be installed and tested by a licensed professional with the permits your area requires.
