Boston's price band
Boston is pricier than 97% of the 195 US metros we price for gas line work.
A short new gas line to one appliance costs $400–$2,000 in Boston, and $860 is typical. Hooking up a range to an existing line is $160–$590, a grill or fire pit line $520–$2,600, and a standby generator line $640–$3,800.
Massachusetts licenses gas fitters separately from plumbers, and gas work needs a permit pulled by a licensed gas fitter. Boston's triple-deckers and brownstones often mean long runs through finished walls.
Installed prices include the pipe, fittings, labor, a shutoff valve and a pressure test. New gas piping is licensed work, and a permit ($60–$410) and inspection are the norm in Boston.

Prices cover the Boston metro. Outlying towns can run 5–10% lower; older buildings in Downtown, South End & Back Bay sit at the top of each range.
Gas line prices across Boston
Where you live in the metro changes the labor, not the pipe. Older homes in Downtown, South End & Back Bay take the longest; jobs in Allston, Brighton & Cambridge tend to come in at or under the city typical.
Downtown, South End & Back Bay
- Per line
- $430–$2,250 per line
- Typical job
- $560–$2,900 / grill or fire pit line
Condos, older houses and mixed-use buildings. New runs often need wall or ceiling openings, and old piping near the meter may need a section replaced to pass the pressure test.
Allston, Brighton & Cambridge
- Per line
- $380–$1,950 per line
- Typical job
- $490–$2,500 / grill or fire pit line
Rentals and older houses. Landlord jobs tend to be quick appliance hookups and short lines, which keeps prices a little under the city average.
Dorchester, Roxbury & Mattapan
- Per line
- $400–$2,000 per line
- Typical job
- $520–$2,600 / grill or fire pit line
Standard pricing for standard work. Easy parking and reachable gas pipe keep labor in line for a range, dryer or water heater line.
Quincy, Lynn & the suburbs
- Per line
- $400–$2,100 per line
- Typical job
- $520–$2,750 / grill or fire pit line
Newer homes, often with CSST already in place, so adding a branch is quick. Yard lines to a grill or generator are the big-ticket jobs.
Real-World Gas Line Costs in Boston
Here's what common gas line jobs cost in Boston in 2026, installed by a licensed pro with fittings and a pressure test.
Range hookup to an existing gas valve — 1–2 hours
Disconnect the old range, fit a new flexible connector, check the shutoff valve, connect, leak-test and light the burners. If there's no gas valve behind the range, it becomes a new-line job at $560–$2,590 with the hookup.
New line to a gas dryer, 15–25 ft — 2–4 hours
A branch off the nearest gas pipe, a shutoff valve, a sediment trap, the hookup and a pressure test. Add $180–$770 if the dryer also needs a new vent to the outside.
Grill or fire pit line across the yard — half a day to a day
Usually buried polyethylene ($25–$64 a foot with trenching), metal risers at each end, a shutoff and a quick-connect at the grill. Concrete or pavers in the way add patching at $130–$520.
Standby generator line — half a day to a day
Generators burn a lot of gas, so the line is usually bigger than a normal branch, and the utility may need to upgrade the meter. Ask whether that fee is in the quote. The permit runs $60–$410.
Gas smell at the range — find and fix the leak
A loose fitting or old connector behind the appliance is the cheap end. A leak inside a wall costs more, and a buried leak with digging costs the most. A service call alone is $95–$350.
How much does gas line installation cost in Boston?
$400–$2,000, with $860 typical. A 10-foot branch off an exposed pipe in a basement or garage is at the low end; a run through finished walls to a kitchen island sits near the top. Quotes above $2,000 usually mean a long run, an outdoor line or a bigger pipe.
If the gas pipe is already behind the appliance, you only need a hookup: $160–$590 for a range and $130–$460 for a dryer. Figures re-checked against 35 sources in November 2026.
Gas line prices in Boston (2026): new lines, hookups and repairs
A short new line to one appliance costs $400–$2,000, a 50+ ft run $1,150–$5,150, and a standby generator line $640–$3,800.
| Line on the quote | Low | Typical | High |
|---|---|---|---|
| New gas line to one appliance (short run) | $400 | $860 | $2,000 |
| Gas range or cooktop hookup (existing line) | $160 | $290 | $590 |
| Gas dryer hookup (existing line) | $130 | $230 | $460 |
| Outdoor grill or fire pit gas line | $520 | $1,150 | $2,600 |

| Gas meter relocation (utility + plumber) | $1,250 | $3,150 | $5,650 |
Black iron vs CSST in Boston: iron runs $19–$44 a foot installed and CSST $14–$31. CSST is cheaper to snake through finished walls; iron is tougher where pipe is exposed. Many jobs use both.
What moves a gas line quote in Boston:
- Distance — every extra foot of black iron adds about $28 installed; CSST about $21.
- Access — open basements and crawlspaces are quick; finished walls, slabs and attics take longer.
- Indoor vs outdoor — buried yard lines run $25–$64 a foot with trenching.
- Gas load — a generator or tankless heater can need bigger pipe and a utility meter check.
- Permit and test — $60–$410 for the permit; the pressure test should be in the price.
Ask every Boston gas plumber for the same five things: the pipe type and length, what's included (valve, hookup, test, permit), any wall or yard patching, the labor warranty, and the start date. Compare those, not the headline price. Get a quote for your gas line work →
Gas Line Cost in Boston by Number of Appliances
One appliance on a short run: $400–$2,000. Two or three appliances: $1,550–$3,850. Gas piping for a whole house with four or more appliances: $2,850–$9,700.
Worked example: a Boston kitchen remodel that moves a gas range 12 feet and adds a gas dryer in the garage is two short runs in one visit. Expect about $1,150 for the new range line and hookup plus $230 for the dryer hookup on a shared branch, plus a $170 permit — about $1,550 all in, not two full jobs.
Adding a standby generator to that job brings in a bigger pipe and often a meter check: about $1,550 for the generator line on top. Doing it in the same visit saves a second service fee and a second permit.
Boston Gas Line Costs by Pipe and Job Type
| Pipe or job type | Cost | Best for |
|---|---|---|
| Black iron pipe | $19–$44/ft installed | Indoor runs in basements and exposed spots, and the main trunk line. Rigid, very durable, more labor to cut and thread. |
| CSST flexible gas pipe | $14–$31/ft installed | Snaking through walls, floors and attics with few fittings. Must be bonded to the home's electrical ground. |
| Copper tubing (where allowed) | $14–$26/ft installed | Some areas and utilities allow it for gas; many don't. Ask your plumber and inspector before choosing it. |
| Underground polyethylene (PE) | $25–$64/ft installed | Buried yard lines to a grill, pool heater, generator or detached garage. Outdoor and underground only, with a tracer wire. |
| Short run to one appliance (10–30 ft) | $400–$2,000 per line | A new range, dryer, water heater or fireplace near existing gas pipe. |
| Long run, 50+ ft | $1,150–$5,150 per line | Across the house, up to an attic furnace or out to a detached garage. |
| Outdoor grill or fire pit line | $520–$2,600 per line | Patios and outdoor kitchens. Often a buried PE run with a riser and shutoff. |
| Standby generator line | $640–$3,800 per line | Whole-home backup power. Needs bigger pipe and sometimes a utility meter upgrade. |
| Flexible appliance connector | $130–$460 per hookup | The last few feet from the shutoff valve to a range, dryer or water heater, fitted as part of the hookup. |
Per-foot price vs what you actually pay — the Boston gas line bill
Black iron costs $19–$44 a foot installed in Boston, but short jobs don't price by the foot. Most plumbers charge a minimum that covers the trip, fittings, a shutoff valve and the pressure test, which is why a 10–30 ft line still lands at $400–$2,000.
Per-foot pricing matters on long runs. A 50+ ft line costs $1,150–$5,150, and a buried yard line $25–$64 a foot with trenching. On top of that, budget $60–$410 for the permit and any patching of walls or concrete.
What's included in a Boston gas line quote (and what costs extra)
A standard installed price covers the new pipe and fittings, a licensed plumber's labor, a shutoff valve at the appliance, a sediment trap where needed, and a pressure and leak test before the gas goes on. The headline price often leaves out:
- Permit and inspection — $60–$410, required for new gas piping in most of the US
- The appliance hookup — $160–$590 for a range, if the quote only covers the line
- Wall, floor or yard patching — drywall repair can add up to $710; a small concrete patch $130–$520
- Meter or utility work — a meter move is $1,250–$5,650; some generator jobs need a utility meter upgrade
Ask whether the pressure test and the permit are in the price; a pro who skips either is cutting a corner that matters.
How far the line runs
Distance is the biggest driver after the minimum charge. A short run is $400–$2,000 in Boston; a 50+ ft run $1,150–$5,150. Putting a new appliance close to existing gas pipe is the easiest saving.
Black iron or CSST
Black iron runs $19–$44 a foot installed and CSST flexible pipe $14–$31. CSST needs fewer fittings through walls but has to be bonded to the electrical ground ($130–$520 if it isn't already).
Basements, crawlspaces and finished walls
An open basement or crawlspace makes a new branch quick. Slab homes, finished ceilings and walls mean drilling, fishing pipe and patching afterward, which adds hours.
Local rules and conditions
Frozen ground in Massachusetts makes winter trenching slow and costly. Buried lines run $25–$64 a foot with trenching; schedule grill and generator lines for the warm months.
Permit and pressure test
New gas piping is pressure-tested before the gas goes on, and most cities inspect it. In Boston budget $60–$410 for the permit; a separate test and inspection visit is $95–$520.
Gas load and pipe size
Every appliance adds to the gas the pipe has to carry. Adding a generator ($640–$3,800) or a tankless water heater can mean bigger pipe from the meter, and sometimes a utility meter upgrade.
Planned vs emergency
A booked job costs $400–$2,000 for a short run; a leak call starts with a $95–$350 service fee, and after-hours work costs more. If you smell gas, leave first and call the utility from outside.
- Bundle the jobs.One visit, one permit and one pressure test can cover a range, a dryer and a grill line. Each extra trip adds a service fee of $95–$350.
- Put appliances near existing pipe.Every foot counts on longer runs: about $28 a foot for black iron and $21 for CSST installed in Boston.
- Ask about CSST for runs through finished walls.Flexible pipe needs fewer openings and fittings than threaded iron. Make sure the quote includes bonding to the electrical ground.
- Get an itemized quote.The permit ($60–$410), the pressure test and any patching should be on the quote, not a surprise on the invoice.
- Dig in the right season.Outdoor lines are cheapest when the ground is dry and unfrozen. Call 811 before anyone digs; it's free and marks buried utility lines.
- Get two quotes.Prices for the same short line in Boston spread from $400 to $2,000. Two written quotes from licensed pros is the easiest way to land near $860.
