"It was a pleasure to work with Eric, we hired him for a complete backyard renovation which included tree removal, leveling the surface and place pavers and a deck on top. Also built a retaining wall. The work came out very nice in part because of the great design ideas that Eric gave us. The project ran into some unexpected issues that Eric was able to overcome nicely. We were impressed how Eric handled the project and met all the deliverables, also his team was extremely polite an professional. Our backyard now looks like the ones advertised in magazines. All this led us to start a new project with him to replace the cracked driveway with nice new pavers."

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.

"We recently had our kitchen and bathroom completely renovated by Geico Builders, and the transformation is beyond what we imagined! After with several other contractors, we decided to go with them and it was the best decision we mage. Mila, our project manager, was fantastic from day one. As first-time remodelers, we had a lot of questions, but Mila guide through every stage with patience and professionalism. The communication was consistent, and any concern we had was handled right away. The team even helped us refine our design ideas and brought them to life with a stunning 3D preview before construction began. Everyone we worked was friendly, organized, and clearly passionate about what they do. The finished kitchen and bathroom are both beautiful and functional exactly what we were hoping for. We couldn't be happier and highly recommend Geico Builders to anyone planning a home remodel!"

Earthquake Retrofitting questions, answered by experts

Ensure proper ventilation, fix leaks, and schedule regular pest inspections to protect your property.

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.

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.

Many homeowners want to know whether earthquake retrofitting is tax deductible. Because it’s often considered a capital improvement, you usually can’t deduct it. In some cases and locations, you may qualify for tax incentives, but you’ll need to talk to a tax professional or the Internal Revenue Service (IRS) about your specific circumstances. You may also be able to find grant money for seismic upgrades, which can lower the cost of your insurance premiums and save money over time.

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.
