Earthquake Retrofitting questions, answered by experts

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.

Ensure proper ventilation, fix leaks, and schedule regular pest inspections to protect your property.

Depending on where you live, your insurance company may require you to have a seismic shut-off valve. It depends on local regulations along with the specific provider. If it’s not a requirement, many providers will offer a discount if you install an earthquake valve, which can save you 5% or more. Contact your provider to learn about potential savings for your plan.

Costs vary as much as timelines. The average earthquake retrofit costs between $3,500 and $8,700. However, homes on hillsides, large homes, and those with rooms over garages can cost up to $12,000 or more. Make sure to get a few estimates to compare the cost and services.

A home with proper earthquake retrofitting can sustain minimal damage in earthquakes of up to 7.0 magnitude, although risks are higher based on how close and deep the earthquake is. A home closer to the earthquake epicenter will sustain greater damage, especially if the earthquake is closer to the surface of the Earth, but retrofitting can help minimize the risk of injuries.
