Gas line repair cost by type
| Repair | Installed price | Good to know |
|---|---|---|
| Minor repair (fitting, joint or valve) | $150–$650 | Fittings, joints and valves |
| Gas leak repair | $200–$1,000 | Priced by severity and location |
| Replace a section of pipe | $400–$1,000 | Cuts out and replaces damaged pipe |
| Replace the whole gas line (meter to appliances) | $3,000–$10,000 | Replaces the line from the meter to the appliances |
Gas line repair prices vary with how accessible the pipe is and how much of it needs replacing. Two national averages cited by cost guides are $400 and $598 for a typical repair, which sit inside the ranges above.
Replacing pipe by the foot
When a stretch of pipe has to be replaced, guides put the cost at roughly $15 to $35 per linear foot installed, including removing the old line. Older black iron or galvanized steel pipe costs more to repair or replace. If the pipe is underground, digging trenches costs about $5 to $12 per linear foot, and one guide puts the high end for an underground leak needing extensive excavation at $2,300.
Pressure test, permit and other extras
| Item | Typical cost | Why |
|---|---|---|
| Pressure test | $75–$200 | Confirms the line is leak-free before gas is restored |
| Leak detection | $75–$300 | Finds the source when it isn't obvious |
| Permit | $50–$300 | Required for gas work beyond routine appliance connection in most places |
| Emergency callout | $150–$400 | After-hours surcharge on top of the repair |
A hydrostatic test, which uses water pressure and is sometimes used on buried or older lines, costs about $150 to $500 and takes 12 to 24 hours. Licensed plumbers and gas fitters commonly charge about $45 to $150 per hour.
