Home Safety

What To Do If You Smell Gas in Your Home

Smell rotten eggs? Get everyone out first. Don't flip switches, unplug anything, or start a car in an attached garage. From outside, call SoCalGas's 24-hour line (1-800-427-2200) or 911. Repairs begin only after the utility makes it safe.

If this is happening right now: leave the house first, call 911 or SoCalGas from outside.

This page is the full explanation for calmer moments. The step-by-step first-minutes playbook is on Emergency Help: What To Do First . Call Power Pro after you're safe: (833) 212-2124 .

What matters most

  • Natural gas is odorized with mercaptan — the rotten-egg smell IS the warning system. Never ignore it or try to air it out and wait.
  • Leave first. Any spark — a light switch, a phone call made inside, a garage door opener — can ignite gas that has reached the right concentration.
  • Call SoCalGas's 24-hour line (1-800-427-2200) or 911 from outside the home. SoCalGas says it will send an employee to investigate any leak indications.
  • After the utility makes the scene safe, a licensed plumber repairs or replaces the leaking line — gas piping is plumbing work that requires a permit.

What is the safe order of operations?

A suspected gas leak has exactly one correct sequence, and it starts with your feet, not your phone.

  • Get everyone — including pets — out of the house immediately.
  • Leave doors open behind you if it's on your way out; don't stop to open windows.
  • Do NOT operate anything electrical on the way out: no switches, no thermostat, no garage door opener.
  • From outside, call SoCalGas's 24-hour emergency line or 911.
  • Don't re-enter until the utility tells you it's safe.

Why shouldn't you search for the leak yourself?

Gas concentrates invisibly, and the ignition energy needed is tiny — static from clothing can be enough at the wrong concentration. Utility responders carry combustible-gas detectors and know how to make a scene safe. Your job is distance; theirs is detection. There is no version of 'just checking the water heater closet' that's worth it.

What happens after the utility clears the home?

The utility's job ends at making the situation safe — often by shutting off the meter or the affected appliance. SoCalGas notes that property owners are responsible for the gas lines on their side of the meter, so getting your appliances back means finding and fixing the actual leak: a failed fitting, a corroded line under the house, a flex connector past its life, or an appliance valve. In Los Angeles, installing gas piping requires a plumbing permit (beyond a short appliance connection), and the California Plumbing Code (§1213.3) requires new gas piping to pass a pressure test at inspection to prove it holds.

How do you prevent the next gas leak?

In our experience, residential gas leaks usually come down to age and vibration, not drama: decades-old black iron rusting in a damp crawl space, appliance connectors that were never replaced when the appliance was, and fittings loosened by years of small earthquakes. SoCalGas advises having customer-owned lines periodically inspected for corrosion and leaks — easy to fold into any plumbing visit — and a seismic shutoff valve at the meter closes the line automatically in a significant quake.

Common questions

I smell gas only faintly, and only sometimes. Is that still an emergency?

Treat any gas odor as real until proven otherwise. Intermittent faint odors are classic early-stage leaks — a fitting that weeps when the line pressure or temperature changes. Call SoCalGas's 24-hour line to have it checked — SoCalGas says it will send an employee to investigate any leak indications — and if a leak is confirmed, have the line repaired by a licensed plumber.

Does SoCalGas fix the leak?

The utility makes the situation safe — investigating the leak and shutting off the meter or the affected appliance as needed. SoCalGas states that property owners are responsible for maintaining the gas lines on their side of the meter, so repairing the house side is the homeowner's job, done by a licensed plumber with a permit and a pressure test.

Can Power Pro come out the same day the utility shuts off my gas?

Yes — a home with the gas shut off has no hot water and possibly no heat, so we treat post-shutoff repairs with emergency priority. Real people answer our phones 24/7, and we handle the repair, the permit, and the inspection and pressure test that come before service is restored.
