Licensed gas line
service.

If you smell gas right now, leave the house first. From outside, call SoCalGas at 1-800-427-2200 and 911. Once it is safe, call us at (909) 312-4516 for the repair. Your safety comes first, always. For non-urgent gas line work, including installation, appliance hookups, BBQ and fire pit lines, and leak repairs, we are California-licensed and pressure-test every job so you can have complete confidence in it.

Gas leak safety

Active gas leak: what to do right now.

  1. Leave the house. Take everyone, including pets. Don't pack, don't grab anything.
  2. Don't flip switches, use electronics or light a flame: sparks and flames ignite gas. That includes the garage door opener and unplugging phone chargers.
  3. Call from outside: SoCalGas at 1-800-427-2200 and 911. Once it’s safe, call us at (909) 312-4516 for the repair.
  4. Don't go back inside until SoCalGas or the fire department says it's safe.

SoCalGas will check for the leak and shut off the gas if needed. They will not repair leaks on your side of the meter: that's our job once they've made the area safe.

Everyday gas work

What we do on gas lines.

Most of our gas work isn’t an emergency. We run, repair and replace gas lines for homes and businesses across our 24 cities:

  • New appliance lines for gas ranges, dryers, water heaters and tankless units.
  • Outdoor lines for BBQs and fire pits.
  • Gas line repair when a line is leaking, corroded or damaged.
  • Gas line replacement and full gas repiping for older homes.

We look at the line and the appliances it feeds, then give you your options in writing, each with one flat-rate price, before any work begins. When the work is done, we pressure-test and leak-check every line before it goes back in service.
