Smell Gas? The Safety Steps That Come Before Any Phone Call

Gas leaks are the one plumbing emergency where the checklist starts before the phone call. The steps, in order, and what proper repair looks like.

By the All Systems Pros service team · Updated July 20, 2026

First, the safety sequence

If you smell gas (the rotten-egg odorant) indoors:

  • Don't flip switches, light flames, or unplug anything — any spark is a risk
  • Open doors on your way out; don't stop to open windows
  • Get everyone (pets included) out and away from the building
  • From a safe distance, call your gas utility's emergency line — SoCalGas: 1-800-427-2200
  • Don't re-enter until the utility clears the building

The utility stops the danger; the repair comes next

The utility's job is to make the scene safe — typically by shutting gas off at the meter. Restoring service is the licensed plumber's job: locating the leak, repairing or replacing the failed section, adding code items like shut-off valves and sediment traps where they're missing, and pressure-testing the system before gas flows again.

What quality gas work looks like

Gas work is licensed work for a reason. Every All Systems Pros gas job — leak repair, rusted line replacement, or a new run for a range, dryer, or tankless water heater — ends with a pressure test and leak check, verified safe before we leave. One of our own public reviews describes exactly this job: a rusted gas line found, explained, and replaced at a fair price, quickly.

Slow leaks are still emergencies

A faint intermittent odor near an appliance, a hissing fitting, dead vegetation over a buried line, or a gas bill creeping up without explanation — small signs deserve the same respect. We dispatch 24/7; the check is fast, and the peace of mind is worth every minute.
