Gas Leak Detection & Repair in Southern California
Smell rotten eggs near a stove or water heater? SoCal Plumbing Co's licensed gas technicians use acoustic leak sensors and certified pressure testing to pinpoint and repair gas leaks across LA, Long Beach, Orange County, and the South Bay — 24/7.
What we do
A suspected natural gas leak is a same-hour emergency. Our gas-certified plumbers respond around the clock with calibrated combustible gas detectors, acoustic leak sensors, and code-compliant pressure-test rigs. We isolate the section of pipe that's leaking, document it for SoCalGas, and repair or replace the affected line to current California Plumbing Code standards.
We service gas leaks at meters, flex connectors, water heaters, furnaces, ranges, fireplaces, pool heaters, and yard lines. Whether the leak shows up as a high gas bill, a SoCalGas red-tag, or a hissing connector behind the stove, we have the tools and the license (CSLB C-36) to handle it from diagnosis through reinstatement.
Every gas job ends with a verified pressure test, a printed report, and — when required — coordination with SoCalGas to safely turn service back on and relight pilots. Permits are pulled on every repair that needs one.

Gas Leak Detection & Repair cost & what affects pricing
A documented pressure test and leak isolation typically lands in the low-to-mid hundreds. Spot repairs of an accessible flex connector or appliance shut-off are quick and inexpensive.
Whole-house gas-line repipes, yard-line replacements, and red-tag reinstatements range from the mid four figures to low five figures depending on length, routing, and trenching. Every quote includes permit, inspection, and SoCalGas coordination.
Every quote is flat-rate, written, and approved before any work begins. Call (562) 366-0303 for a same-day estimate.

Frequently Asked Questions
Is a tiny gas smell really an emergency?+
Yes. Natural gas is odorized intentionally so any whiff is detectable — leave the home, don't flip switches, and call SoCalGas plus a licensed plumber from outside.
What should I do if I smell gas?+
Leave the house, do not flip light switches, and call SoCalGas (1-800-427-2200) from outside. Then call us at (562) 366-0303 — we can usually be on-site within 60–90 minutes to find and repair the leak after SoCalGas shuts the meter.
How do you find a gas leak?+
We use calibrated combustible gas detectors, acoustic leak sensors, and a code-compliant pressure test on the line. For buried yard lines we add a tracer-gas method to pinpoint the leak without trenching the whole yard.
Do I need a permit to repair a gas line?+
Yes — most gas line repairs and any new gas piping require a city permit and inspection in Southern California. We pull every permit required and meet the inspector on-site.
Can you remove a SoCalGas red-tag?+
Yes. We repair or replace the line that triggered the red-tag, run a documented pressure test, and coordinate the reinstatement with SoCalGas so service can be safely turned back on.
