"Updating our home was a dream we have had for years. But finding a good contractor in Bay Area was so difficult, that we almost gave up. We were introduced to United C Construction by our architect(who we also love!) It was exhausting trying to find someone trustworthy and not overpriced. We had luck of working with Osmar which during the project we had clear communication, expectation of setting, professionalism and superior craftsmanship. He walked us through every step of the way, and helped problem solve tough permitting and structural issues in Berkeley!"

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 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.

Projects will vary based on size and scope, but an average earthquake retrofit takes between two weeks and two months. This includes the initial evaluation and plan, bidding and contract paperwork, permitting and approval process, actual work, and final inspection. Your contractor should give you a more accurate time estimate for your specific project, and they may be able to estimate how long the permitting process will take for your area.

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.

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.

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.
