Earthquake Retrofitting questions, answered by experts

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.

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.

It is not advisable to try to retrofit your home without the expertise of a professional. These projects usually require a consultation with a structural engineer and a plumber for any gas-related adjustments. Working with a professional earthquake retrofitting contractor is the best way to ensure that any structural work done to your home will help protect you and your family.

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.

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.
