"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."

Geico Builders specializes in meeting your expectations before, during, and after the project is complete. Our most upstanding quality is our accountability--you can expect us to own the work we complete for your home. Of course, we know accountability means nothing without proof, which is why we are happy to offer a 2-year workmanship warranty to all of our clients. This is a rare quality for this industry, but we wanted to prove to you that we stand by our craftsmanship through our home remodeling construction services. Every Crew at Geico Builders has been professionally trained and will treat your home with integrity and respect.

"We used Geico Builders for our bathroom remodel. We collected a few quotes, and we felt like the quote for the value was the best. I appreciated the clear scope and payment schedule. We started with a tiny bathroom and had plans to remove a couple of walls to make it larger. Leading up to demo day, our project manager Mila and the team pulled permits and helped us understand which finishes/materials we needed to order. I had a clear idea of our design vision, so I didn't need a lot of assistance there, but I found the 3D rendering helpful to see. Our project took a little over 5 weeks. The foreman David and crew did a great job. I was many specific requests, and I felt like David always did his best to incorporate my requests. We had a few hiccups, as with any project. We ran out of tile, which caused a small delay. The crew also misplaced some of our shower fixtures and we had to reorder them. The team was able to cover the cost of these, which I appreciated. I liked how we had a group to stay on top of updates. There were times when I would have liked more communication regarding the crew's schedule, delays, etc. but overall, I felt like my questions were always answered. Love my new bathroom, thank you."

Earthquake Retrofitting questions, answered by experts

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.

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.

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.

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.

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.
