"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 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

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.

Hearing or feeling vibrations in your house can be unsettling, but there are a few possible causes for a vibrating noise in your wall or floor. Light bulbs and fixtures, circuit breakers, loose pipes, or faulty wiring could all cause vibrations. If you’re not sure what’s causing the vibrations, you can call a contractor to assess your home and narrow down the cause.

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.

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.

Generally, the retrofitting process can take two to four weeks. Your contractor will let you know if staying in your home for the entire project is feasible. However, most people are able to remain at home. If your home is undergoing earthquake rehab, it's more likely that you'll need to leave until work is complete. Your earthquake insurance may cover boarding costs if your home is deemed unsafe.
