"I hired Secure Seismic to do a retrofit of my single story ranch built in the 1970s. Though I'm in the southern Willamette Valley and a ways from Portland, Daryl came down to give me a free estimate. Secure Seismic came in below their competitors and Daryl discusssd the plan with me in depth. Based upon the quality of the reviews, I hired Secure Seismic. They scheduled out within a couple of weeks. Johny the foreman kept me on the loop while they were at my house. They completed the job within a day and left the site clean. Pieces of drywall cut for access in the garage were thoughtfully replaced and will take little effort to clean up. Thanks for great work! I already sleep a little better knowing that my house will likely be okay when the big one hits."

Earthquake Retrofitting questions, answered by experts

Some cities or states may require you to have an earthquake gas shut-off valve. Your insurance provider may also have requirements for installing this valve. Even if you don’t have to have one by law, it’s wise to have a natural gas plumber install one anyway. These devices can be lifesaving and prevent fires or explosions in the event of a gas leak.

Earthquake gas shut-off valves, or seismic gas shut-off valves, are safety devices that attach to your natural gas line. When an earthquake hits, the valve automatically turns off the flow of gas. Earthquake gas shut-off valves can prevent gas leaks, which are especially dangerous after a quake due to the risk of fire and explosion.

Even if you invested in the cost of a gas shut-off valve for your oven and other appliances, it’s a good idea to add a seismic shut-off valve as an extra safety measure. 

Gas shut-off valves for appliances are manual, meaning someone has to cut off the flow of gas. This leaves room for error, as you might not be home or might be too distracted to think about gas lines during an earthquake. An earthquake valve is automatic and will protect your home from gas-related disasters in the event of an earthquake.

Grounding is a great first step to prevent electrical shock, but you can take it further with GFCI outlets and AFCIs (arc fault circuit interrupters). In particular, AFCIs help protect against the type of electrical arcs that cause fires, like if a mouse chews on a wire or your laptop starts overheating at the wall. These are required in some areas of your home.

Almost all new buildings in California need an earthquake shut-off valve. The requirements for an earthquake gas shut-off valve (and who can install it) depend on where you live. For example, according to the Los Angeles Municipal Code, you’re required to hire a licensed contractor to install one whenever you build, sell, or renovate a home. Check with your local building department for your city’s laws on installing, permitting, and inspecting earthquake shut-off valves.
