Why licensing matters here
Anyone can call themselves a handyman; gas work legally requires a licensed contractor — and doing it wrong risks your family’s safety and your insurance coverage. We’re licensed CA #1067555 (verify at cslb.ca.gov); we pull permits, and every gas job is pressure-tested and inspected. That’s not a formality — it’s how you know it’s safe.
LA’s earthquake gas shut-off valve rule
The City of Los Angeles requires a seismic gas shut-off valve in several situations: buildings first permitted on or after September 1, 1995; alterations or additions worth more than $10,000 (for homes, permits issued on or after January 10, 1998); any time a gas meter is altered or replaced; and before a property is sold, prior to the close of escrow.
A seismic valve shuts your gas off automatically in a strong earthquake, when broken lines and appliances are most likely to leak. We install and permit them across LA and the cities around it. See earthquake gas shut-off valve installation.
Your side of the meter, and CSST
SoCalGas maintains the system up to the meter. Everything after it is the property owner’s responsibility: the piping to your appliances, and any buried lines to a pool or spa heater, BBQ, or fire pit. SoCalGas recommends having buried metal lines inspected periodically for corrosion and leaks.
If your home has standard yellow CSST, the flexible gas tubing, it has to be bonded to the electrical grounding system with at least a 6 AWG copper conductor. Newer black, arc-resistant CSST follows its manufacturer’s installation rules. If you’re not sure yours is done right, we’ll check it.
