Why Ontario homes need gas leak detection

Ontario's historic Euclid Avenue district carries gas infrastructure from the city's founding era, with SoCalGas serving the region for coordination on any confirmed leak.

Gas service in Ontario is provided by SoCalGas, and any leak confirmed on the utility side of the meter gets reported and coordinated directly with them as part of the repair process.

What gas leak detection involves

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

Ontario customers on 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.”
