"The employees were great. A couple of days there was only 1 man on the job due to illness. The company did not replace him, so the 1 man had to work alone, slowing down the completion of the project. Art and Johnny were great to work with. Communication with the office was a little lacking, but overall we are happy with the work."

Earthquake Retrofitting questions, answered by experts

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.

An earthquake retrofit is essential for safety in an earthquake-prone area. Without proper retrofitting, your home is at risk of sliding off the foundation, shifting, or collapsing.

You may also require a retrofit if your home was built before 1980 when building codes began requiring reinforcing, bracing, and bolting for new construction. You may not be eligible for insurance to help pay for earthquake-related damages without a retrofit.

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.

Hearing or feeling vibrations in your house can be unsettling, but there are a few possible causes for a vibrating noise in your wall or floor. Light bulbs and fixtures, circuit breakers, loose pipes, or faulty wiring could all cause vibrations. If you’re not sure what’s causing the vibrations, you can call a contractor to assess your home and narrow down the cause.
