Locally, Privately Owned & Operated Response within 24 Hours!!

"This man stole thousands of dollars from us. We fired him 6 months in to what was supposed to be a 4-6 week job after only doing a fraction of the work...all done out of order with constant delays. The owner Mr Borman, is a dishonest and incompetent con who won’t return our money. He has devalued our property and brought great hardship."

Earthquake Retrofitting questions, answered by experts

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.

Earthquake retrofitting can increase your home value, making it a great return on investment. This feature is especially valuable in areas prone to earthquakes. Besides the increased safety value (not only for your family but for the next family who moves in), earthquake retrofitting also helps lower homeowners insurance rates. In addition, having your home earthquake retrofitted can make it easier to get a home loan since they are considered lower risk.

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.

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.
