A gas leak is not something to wait on. Even a small leak at a fitting, valve, or old flex connector can build up inside a closet, attic, or crawl space, and it can get your gas shut off with a red tag until it's fixed. Most leaks we find in Los Angeles homes come from corroded black iron pipe, loose unions, worn appliance connectors, old shutoff valves, or lines that were added on without being done to code. We use an electronic gas detector to trace the line and test every fitting, then confirm the exact spot with a leak-detection solution. Once it's repaired, we pressure-test the whole line before turning the gas back on, so you know it's sealed.
Why Gas Leaks Need a Licensed Plumber
What We Do
Gas Leak Detection
Smell gas near an appliance, the meter, or in a room? We trace the line with an electronic gas detector, test every fitting and valve, and pinpoint the exact source instead of guessing.
Gas Line & Fitting Repair
We repair or replace the leaking section, union, valve, or appliance connector with code-approved parts. Corroded pipe gets replaced, not patched. Every repair is pressure-tested before the gas goes back on.
Red Tag & Inspection Repairs
Got red-tagged by SoCalGas or flagged on a home inspection? We fix the problem, bring the work up to code, and test the system so the gas company can turn your service back on.
Code-Approved Parts We Use
We repair gas lines with black iron pipe for exposed and indoor runs, CSST flexible gas piping from Gastite and TracPipe where it fits best, and polyethylene for underground lines. Shutoff valves and appliance connectors come from BrassCraft, Dormont, and Watts. Every part is approved for California gas systems. After the repair, we pressure-test the line, relight your pilots, and check that your water heater, furnace, range, and dryer all fire correctly before we leave.
What To Expect
If you smell gas strongly, leave the home first and call SoCalGas or 911 from outside. For a faint smell or a red tag, we start by checking your meter, your gas lines, and every gas appliance in the home. We use an electronic detector to find the exact leak, show you what we found, and give you a flat-rate price before any work starts. Once you approve, we shut off the gas, make the repair, and pressure-test the line to confirm it holds. Then we turn the gas back on, relight every pilot, and make sure every appliance runs right. Most leak repairs are done the same day in just a few hours.

Frequently Asked Questions
-
If the smell is strong, leave the home right away. Don't flip light switches, use your phone indoors, or light anything. Once outside, call SoCalGas or 911. If it's safe and you know how, you can shut the gas off at the meter. For a faint or occasional smell near an appliance, call us and we'll use electronic leak detection to find the source.
-
A red tag means SoCalGas found an unsafe condition, like a gas leak or an appliance that isn’t working safely, and shut off the gas to it. The tag stays until a licensed plumber fixes the problem. We find and repair the issue, pressure-test the line, and then SoCalGas can come back to turn your service on.
-
Yes, in most cases. Same-day service is available, and most leaks at a fitting, valve, or appliance connector are found and fixed in one visit. Bigger jobs, like replacing a long corroded section of pipe, can take longer, and we’ll tell you up front.
-
The most common causes are corroded black iron pipe, loose or worn unions, old flex connectors behind appliances, worn shutoff valves, and lines that were added on without being done to code. Earthquakes and settling can also loosen fittings over time.
-
We use an electronic gas detector to trace the line and check every fitting, valve, and connector, then confirm with a leak-detection solution at the suspected spot. After any repair or new installation, we pressure-test the system to make sure the whole line holds.
-
Most leak repairs take a few hours, including finding the leak, making the repair, and pressure-testing the line. Replacing a larger section or an underground line can take a full day. You’ll get a clear timeline with your flat-rate price.
