Evergreen Seismic, LLC is the Puget Sound's most trustworthy residential earthquake retrofit contractor. Our mission is to provide the highest quality of service, along with the most affordable prices. We take great pride in our work, and customer safety and satisfaction is our number one goal. Our clients demand and deserve excellence and we are committed to meet these expectations each and every time. We offer the experience of hundreds of retrofit installations, along with the highest quality products, valuable design and engineering, and stellar results.

"Matt and the Evergreen Seismic team were communicative, honest, and collaborative throughout our retrofit. When I reached out initially, he helped me learn about the retrofit process, and even encouraged me to consider doing it myself. I really appreciated that — it'd be so easy for a professional in his position to scare a client into getting the work done, but he did the opposite. He also gave us a competitive quote, and offered to match any other we got elsewhere. I ultimately decided to hire him, and was glad I did. He and his team got the work done in a timely and orderly fashion. Our foundation turned out to be a little unusual, which took more time than anticipated, but he walked us through what they were doing to accommodate the difference, and did not ask for an additional fee for the extra time spent. They handled all the city permitting and mailed us the paperwork to keep on file."

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.

First, you can expect the project to be loud. If you have pets, you might want to take them to a friend's house during the day so they are not disturbed by any of the loud noises. In addition, you’ll need to provide the retrofit team access to areas of the house that will need to be worked on, meaning you’ll need to relocate personal items, clear clutter, and make pathways for the crew. Once the project is complete, a local building inspector will conduct a final inspection to ensure that the retrofitting is up to code.

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.

According to the Earthquake Country Alliance—a public and private alliance in California that works to improve earthquake and tsunami readiness—reports that unreinforced masonry, such as stone, bricks, and hollow clay tiles, is more susceptible to earthquake damage. The mortar between bricks isn’t as stable as other building materials and methods.

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.
