What Gas Line Repair Covers (and What It Does Not)
We work on gas piping after the meter: black iron, CSST and approved flexible connectors that feed your water heater, furnace, range, dryer, grill and fire features.
CPS Energy owns the meter and the utility side. If CPS shut your gas off, a licensed plumber fixes the customer-side piping, then CPS restores service. This is the most common point of confusion in San Antonio threads, so we explain it up front.
| Situation | Who handles it |
|---|---|
| Smell of gas, hiss, evacuation | 911 and CPS Energy first |
| Leak at or before the meter | CPS Energy |
| Leak in house or yard piping after the meter | Licensed plumber (Stark) |
| New appliance line, replacement, extension | Licensed plumber (Stark) |
| Restoring gas after repair | CPS Energy, after repairs pass |

Gas Line Repair, Replacement and Installation
Leaking joint or fitting
Cut out the failed section and replace it with proper fittings. Patching a threaded joint with tape or sealant is not a repair.
Corroded or damaged pipe
Old black iron can corrode, and soil or moisture can attack buried pipe. Replacement is often safer than repeated repairs.
Appliance hookups
New range, dryer, tankless heater or outdoor kitchen with a shut-off valve at each appliance.
Outdoor gas lines
Grills, fire pits and pool heaters need buried or protected piping, correct depth and a locate before digging.
Gas Pressure Testing and Inspection
After any repair or new run, the piping should be pressure tested and checked at every joint. A test is how we prove the work holds, not an upsell. When a permit or inspection applies, we coordinate it.
What Affects Gas Line Repair Cost
Cost depends on access, pipe length, pipe material, trenching or slab work, number of appliances and permits. Any price you see online without a visit is a general range, not a quote.
| Factor | Why it matters |
|---|---|
| Access | Attic, crawl space, slab or yard digging changes labor |
| Length and size | Longer or larger lines cost more pipe and time |
| Material | Black iron, CSST or buried pipe each need different methods |
| Permits and testing | Required for many jobs and included in a written estimate |
Two quotes that look different often leave out different things. Ask whether testing, permits, shut-off valves and restoration of drywall or soil are included.
Why Gas Lines Fail Here
San Antonio has many older homes with decades-old black iron, shifting clay soil and caliche that can stress buried piping, and a lot of outdoor living with grills and fire features added after the original build. Appliance swaps are a common trigger: a new range or water heater exposes an old connector or undersized line.
Seasonal Gas Safety in San Antonio
Spring
Check outdoor grill and fire pit connections before cookout season.
Summer
Inspect pool heater and outdoor kitchen lines. Heat and sun age flexible connectors.
Fall
Before heating season, have furnace and water heater gas connections inspected.
Winter
Cold snaps raise gas demand. Know where your shut-off is and keep vents clear.
