Gas Line Installation Cost: Per Foot & By Project (4 References)

Gas line installation costs $260 to $2,000 for most projects, or $15 to $50 per linear foot.¹²³ Extending an existing line for one appliance runs $350 to $800; a new service line from the street is $2,000 to $10,000+ (HomeGuide).² Thumbtack’s project data shows most people paying around $470.⁴ Prices below are national averages* for 2026.

*National averages, not local quotes. Your price depends on line length, material, trenching vs. boring, and which side of the meter the work is on.

Quick math: check any per-foot quote against the totals: 25 feet at $15 to $25 (simple) = $375 to $625, and Fixr’s $800 average for exactly that job fits once fittings and the shut-off valve are in.²³ Angi’s $15 to $25 per foot and HomeGuide’s $15 to $50+ do not disagree — Angi prices typical underground runs, HomeGuide spans simple ($15 to $25) to complex ($35 to $50+).¹²

Cost by project type

Project	Cost (HomeGuide)	What it covers
Extend existing line	$350 – $800	Tap existing line for one nearby appliance (10–30 ft)
Single appliance from meter	$500 – $2,000	New line, meter to one appliance
Multiple appliances	$1,200 – $3,000	Lines to 2–3 appliances
Whole-house conversion	$2,200 – $7,500	Interior lines for 4+ appliances
New service line from street	$2,000 – $10,000+	Main to meter, plus meter install

Thumbtack splits the same boundary differently: hooking an appliance to an existing line averages $243 to $823, while supplying a new line for appliances runs $431 to $1,609.⁴ Angi’s $260 to $820 typical range describes the smaller jobs; its $120 to $1,350 full range covers most residential work.¹

Cost per linear foot

Line length	Simple ($15 – $25/ft)	Complex ($35 – $50+/ft)
10 ft	$150 – $250	$350 – $500+
20 ft	$300 – $500	$700 – $1,000+
30 ft	$450 – $750	$1,100 – $1,500+
50 ft	$750 – $1,300	$1,800 – $2,500+
100 ft	$1,500 – $2,500	$3,500 – $5,000+

Fixr prices the work type instead: extension $10 to $20 per foot, new install $15 to $25, relocation $15 to $25, replacement $23 to $35 (old line removal included).³ Furnace lines sit at the top of the per-foot band ($20 to $25) because they need larger pipe; water heater lines run $10 to $18.³

Pipe materials

Material	Material cost per ft (HomeGuide)	Notes
HDPE (polyethylene)	$1 – $3	Preferred underground; corrosion-resistant
Copper	$2 – $6	Restricted for gas in some areas
CSST (flexible stainless)	$2 – $10	Easy install; needs bonding/grounding
Galvanized steel	$3 – $9	High-pressure, indoor/outdoor above-ground
Black iron	$5 – $10	Traditional interior choice

Materials are a small slice of the bill — labor dominates, which is why complex routing doubles the per-foot price even on cheap pipe, our judgment from the per-foot tables.¹²

Cost by appliance

Appliance	Thumbtack average range
Outdoor BBQ / grill	$303 – $1,030
Dryer	$318 – $1,081
Furnace	$349 – $1,188
Fireplace	$357 – $1,215
Water heater / boiler	$357 – $1,215
Stove / oven	$376 – $1,278

Grills and dryers are the cheapest connections; anything needing a long run or bigger pipe (stoves, fire pits) lands higher.⁴

Street side vs. your side of the meter

Everything from the main to the meter is the utility company’s job — often free when the meter is within about 100 feet of the street; you pay only for the excess distance and restoring your landscaping (Fixr).³ The meter itself is $250 to $425 when not included.³ From the meter inward, it is your plumber’s work: interior lines for three to four appliances run $1,250 to $1,600, hookups $220 to $350, shut-off valves $210 to $500 (Fixr).³

Trenching vs. directional boring

Open trenching costs $5 to $15+ per linear foot and disrupts landscaping; horizontal directional drilling (HDD) costs $10 to $30 per foot but goes under driveways and established yards without excavation (HomeGuide).² HDD often nets out cheaper once landscape restoration counts, our judgment. Permits run $100 to $300 (Angi).¹

Worked examples

Example 1 — extend a line 15 feet for a dryer. Simple interior run: 15 × $15 to $25 = $225 to $375, our arithmetic; HomeGuide’s extension band ($350 to $800) adds fittings and the shut-off.²³

Example 2 — new 25-ft furnace line. 25 × $20 to $25 = $500 to $625, our arithmetic; Fixr’s $800 national average for exactly this job adds the valve and fittings.³

Example 3 — electric-to-gas kitchen conversion. New line for a stove ($376 to $1,278, Thumbtack) + underground run at complex rates if routed outside.²⁴ Budget $100 to $300 for the permit (Angi).¹

FAQ

Can I install a gas line myself? No. Licensed pros only — a bad connection is a leak-and-explosion risk, and permits plus inspection are required (Angi).¹

Who pays for the line from the street? Usually the utility, up to about 100 feet; beyond that you pay the difference, plus your own landscaping restoration (Fixr).³

Why do some quotes price per foot and others per project? Per-foot suits simple runs; project pricing bundles fittings, valves, and complexity. Convert both to per-foot equivalents before comparing, our advice.

Does CSST save money? Often on labor — it snakes through framing with fewer fittings — but it requires bonding and grounding for lightning protection (HomeGuide).²

How do I know if I have a leak? Smell of rotten eggs, hissing, or dying vegetation over a buried line; leave the house and call the utility first, then a pro (Angi).¹

DIY shopping: gas leak detectors (plain link, no affiliate relationship) — the one purchase every gas home should make; the piping itself is licensed-pro work, no exceptions.
