Natural gas lines running to Compton's postwar tract homes are the same age as the copper water pipe we trace for pinhole and slab leaks — often 60 to 80 years in the ground or crawling along a foundation wall. Steel gas pipe corrodes on its own timeline, joints and flare fittings loosen with decades of the same seismic micro-movement from the Newport-Inglewood Fault Zone that stresses water lines, and appliance connectors left unreplaced through a few water heater swaps eventually fail. A gas leak rarely announces itself as clearly as a water leak does. There is no puddle, no warm patch on the floor, no climbing water bill. Usually it is a faint rotten-egg smell near a meter, stove, or water heater, a hissing sound, or dead vegetation over a buried line — and by the time any of those are obvious, the leak has often been active for a while.
What to do first if you smell gas
Do not flip light switches, do not use a phone inside the house, and do not try to find the leak yourself with a lighter or match. Get everyone out, and if you can safely reach it without lingering, shut the gas off at the meter valve using a wrench — a quarter turn so the valve is perpendicular to the pipe. Call SoCalGas from outside the home, then call us at (424) 544-0235. We coordinate with the utility rather than working around them, since only SoCalGas can restore service to the meter after a repair.
How we locate a gas leak
Once the utility has confirmed it is safe to proceed, we pressure-test the line in sections and use a combustible gas detector to sniff along every joint, union, and appliance connection rather than guessing based on smell alone, which is unreliable outdoors and can be misleading indoors near multiple appliances. Buried yard lines get traced the same way we trace buried water lines — acoustic and tracer-gas methods that mark the failure point without trenching the whole run blind.
Common failure points in Compton homes
- Flexible appliance connectors. The corrugated line running to a stove, dryer, or water heater has a service life; if a fixture has been replaced but the old connector reused, that is a common failure point.
- Meter set and regulator. Older meter sets on 1940s–60s tract homes sometimes have deteriorated pipe dope or thread sealant that was never rated for the pressure now running through it.
- Buried steel service lines. Uncoated or poorly coated steel pipe corrodes in Compton's alluvial soil the same way it does anywhere else, and a leak here shows up as a smell in the yard or, in bad cases, dead grass in a straight line.
Repairs are permitted work through the City of Compton's Building and Safety division when they involve anything beyond an appliance connector swap, and we pull those permits so the fix is documented and inspected.

Is it safe to stay in the house if I smell a little gas?
No. Leave immediately and call from outside. A faint smell can escalate quickly in an enclosed space, and there is no way to judge concentration by nose alone.
Will SoCalGas find the leak for me?
SoCalGas responds to reported leaks and will shut off service if needed, but locating the exact failure point and completing the repair is licensed plumbing work, which is where we come in.
How much does gas leak repair cost?
It depends entirely on where the leak is — an appliance connector swap is a same-visit fix, while a buried service line replacement is a larger job. We quote in writing after locating the leak, before any repair starts.
Can a gas leak happen without a smell?
Rarely, since mercaptan is added specifically to make leaks noticeable, but a very slow leak outdoors can disperse before it is noticeable. Dead patches of grass over a buried line or an unexplained rise in your gas bill are both worth a call.
