The City of Los Angeles requires the installation of a seismic gas shutoff valve before the close of escrow. The valves automatically shut off the gas supply to the home when there is a 5.0 earthquake or higher. If you’re a home owner and you don’t have a seismic gas shutoff valve installed why wait until you’re ready to sell your home? Take the necessary steps to protect your own family now. We’ll install and maintain the valve for you.
