Cost Snapshot
$260 – $820
Gas line installation or repair typically costs between $260 and $820, based on Angi's 2026 cost data. Angi did not publish a national average in the text we reviewed, so the $540 shown is the midpoint of that typical range, not an Angi average. Underground runs are priced at $15 to $25 per linear foot, so a long run costs much more: our calculation from that rate gives $375 to $625 for 25 feet, $750 to $1,250 for 50 feet and $1,275 to $2,125 for 85 feet. Trenching ($4 to $12 per foot), a new meter ($300 to $600), permits, and pressure testing are additional line items.
Typical planning range based on the published references reviewed for this guide. Use it to prepare questions and compare written, itemized contractor proposals. Actual costs vary with project scope, materials, access, permits, and local conditions.
Parts vs. Labor Breakdown
| Component | Typical range | What it covers |
|---|---|---|
| Materials / equipment | $25 – $225 | Pipe and fittings. Angi lists materials at about $1 to $9 per linear foot depending on material; the range shown is for a 25 ft run. As a retail reference, Home Depot listed a HOME-FLEX 1/2 inch by 25 ft CSST gas pipe (model 11-00525) at $56.85, about $2.27 per foot, on 2026-10-09; pipe only, without connectors. |
| Labor | $68 – $600 | Licensed plumber or gas fitter labor. Angi reports $45 to $200 per hour. The 1.5 to 3 hours is a planning assumption for a short run. Benchmark: BLS reports a May 2025 national median wage of $30.67 per hour for plumbers and pipefitters. |
| Permits | $100 – $300 | Gas permit, which Angi lists at $100 to $300. Inspection is quoted separately at $50 to $75, and some regions charge up to $300. |
| supplies additional | $75 – $150 | Pressure test, which Angi lists at $75 to $150. Some local codes require a longer test that can reach $500. |
Cost by Size & Scope
| Size / scope | Typical coverage | Estimated installed cost | Average |
|---|---|---|---|
| Short underground run (25 ft) | Calculated at $15 to $25 per ft; not an Angi table row | $375 – $625 | $500 |
| Medium underground run (50 ft) | Calculated at $15 to $25 per ft; not an Angi table row | $750 – $1,250 | $1,000 |
| Long underground run (85 ft) | Calculated at $15 to $25 per ft; not an Angi table row | $1,275 – $2,125 | $1,700 |
Cost by Equipment & Installation Method
| Type | Spec | Typical cost | Details |
|---|---|---|---|
| Black Iron Pipe | Material only, per linear ft | $5 – $9 per ft | Rigid threaded steel pipe, a long-standing choice for interior gas piping. |
| Stainless Steel (CSST) | Material only, per linear ft | $2 – $5 per ft | Flexible corrugated stainless tubing that is quick to route. Home Depot listed a 25 ft roll of 1/2 inch HOME-FLEX at $56.85 on 2026-10-09, about $2.27 per ft. |
| Galvanized Steel | Material only, per linear ft | $2 – $9 per ft | Zinc-coated steel pipe; acceptance for gas varies by local code. |
| HDPE (Underground) | Material only, per linear ft | $1 – $2 per ft | Polyethylene pipe used for buried gas service lines. |
| Copper | Material only, per linear ft | $1 – $3 per ft | Copper tubing; many jurisdictions restrict or prohibit it for gas, so check your local code first. |
Additional Line Items Often Needed
| Item | Typical cost | Necessity | Notes |
|---|---|---|---|
| Trenching | $4 – $12 per ft | As Needed | Angi lists trenching as a separate item from the per-foot installation price. |
| New Gas Meter | $300 – $600 | As Needed | Only when the project needs a new or relocated meter. |
| Permit | $100 – $300 | Required | Fees and rules vary by city. |
| Pressure Test | $75 – $150 | Required | Some local codes require a longer test that can reach $500. |
| Inspection | $50 – $75 | Required | Some regions charge up to $300. |
Frequently Asked Questions
How much does it cost to install a gas line?
Most gas line projects cost between $260 and $820 according to Angi's 2026 data. Cost rises quickly with run length: underground lines are priced at $15 to $25 per linear foot, so a 50 ft run is roughly $750 to $1,250.
How much is gas line installation per foot?
Angi prices underground installation at $15 to $25 per linear foot. Material alone is $1 to $9 per foot depending on the pipe, and trenching adds $4 to $12 per foot. These are separate bases, so do not add them blindly.
How much does it cost to run a gas line 50 feet?
At Angi's underground rate of $15 to $25 per foot, a 50 ft run comes to about $750 to $1,250. This is our calculation from the per-foot rate, not an Angi table value, and it does not automatically include a meter, permits, or pressure testing.
Which gas line pipe materials cost the least?
Per linear foot and without labor, Angi lists HDPE at $1 to $2, copper at $1 to $3, stainless steel at $2 to $5, galvanized at $2 to $9, and black iron at $5 to $9. Not every material is allowed for gas in every location, so the installer and local code decide.
What extra costs come with a gas line?
Expect a permit ($100 to $300), a pressure test ($75 to $150, sometimes up to $500), an inspection ($50 to $75), trenching ($4 to $12 per foot), and a new meter ($300 to $600) if the job needs one.
Why does this guide not show a national average from Angi?
The Angi text we reviewed gave a typical range of $260 to $820 but no national average. Instead of inventing one, we show the midpoint of the range where a number is required and label it as such.
