Customer Success Story · Gas Leak Detection

When The Nguyen Family in Platinum Triangle, Anaheim called about higher than usual gas bills with no added usage, a technician got out the same week. We combine handheld electronic sniffers with pressure-decay testing on the line to confirm both the presence of a leak and its approximate location, then coordinate next steps with your utility or a licensed repair contractor. The technician's on-site explanation meant there were no surprises once the repair crew arrived.

What is gas leak detection?

Gas leaks are a safety priority, not a wait-and-see issue. Our technicians use electronic gas detection equipment and line pressure testing to trace leaks along buried and exposed gas lines, at meter connections, and at appliance shutoff valves. If you smell gas or hear a hiss near a gas line or appliance, treat it as an emergency: leave the area, avoid switches or open flame, and call your gas utility's emergency line before anything else.

We combine handheld electronic sniffers with pressure-decay testing on the line to confirm both the presence of a leak and its approximate location, then coordinate next steps with your utility or a licensed repair contractor.

Signs you may need gas leak detection

  • A rotten-egg or sulfur smell near appliances, meters, or the yard
  • A hissing sound near a gas line, meter, or appliance connection
  • Dead or discolored patches of vegetation in an otherwise healthy lawn
  • Higher than usual gas bills with no added usage
  • Pilot lights that won't stay lit
  • Physical damage or corrosion visible on exposed gas piping

How gas leak detection works

  1. Schedule your inspection

    Call or request an appointment online. Same-day slots are available across California for active leaks.

  2. On-site diagnostic

    A technician arrives with acoustic listening equipment, thermal imaging, and pressure or camera tools matched to your specific leak type.

  3. Pinpoint & confirm

    The leak's exact location is marked and explained to you in plain terms, so nothing gets opened up on a guess.

  4. Clear next steps

    You receive a written diagnostic report you can hand to your plumber, restoration team, or insurance company, with repair or fix options discussed on the spot.

What California homeowners say about gas leak detection

★★★★★

“The floor in our hallway had a warm spot for weeks. They found the slab leak in under an hour with the listening equipment and marked a tiny area instead of tearing up the whole hallway. Huge relief.”

MTMarcus T. · Los Angeles, CA
★★★★★

“Our water bill jumped for two months straight and we couldn't find why. Turned out it was a slow leak behind the water heater. Professional, on time, and explained everything on the spot.”

PRPriya R. · Los Angeles, CA
★★★★★

“Salt air had corroded a fitting outside near the meter box. They traced it with the acoustic equipment without digging up my whole side yard first. Appreciated the straightforward report.”

DKDaniel K. · San Diego, CA
★★★★☆

“Good experience overall, technician was knowledgeable and thorough. Took a little longer than expected but they were clearly being careful about pinpointing the exact spot before marking it.”

AMAngela M. · San Diego, CA
★★★★★

“Old Victorian with plaster walls everywhere, so I was dreading this. They used thermal imaging and found the leak behind one wall panel instead of opening up the whole room. Saved us a big repair bill.”

CBChris B. · San Francisco, CA
★★★★★

“Ground near our garage had been soft for a while. Turned out to be the main line. They marked the exact dig spot and our plumber only had to open a two-foot section instead of the whole path.”

WLWei L. · San Francisco, CA

Gas Leak Detection FAQs

What should I do if I smell gas right now?Toggle answer
Leave the building immediately, avoid using light switches, phones, or anything that could spark, and call 911 or your gas utility's emergency line from a safe distance before contacting anyone else. Do not attempt to locate the leak yourself.
Can you find a leak in an underground gas line?Toggle answer
Yes, underground gas line leaks can often be traced using surface gas detection surveys and pressure testing, similar to how we approach underground water line leaks, without excavating the entire run.
Do you also repair gas leaks or only locate them?Toggle answer
We locate and confirm gas leaks and can coordinate repair or replacement work. Because gas work has specific code and utility requirements, we'll walk you through the safest and most compliant path forward for your specific situation.
