Geico Builders specializes in reliable home remodeling backed by accountability, skilled craftsmanship, training and a workmanship warranty you can trust. Our most upstanding quality is excellent service we provide to our customers.

"We hire Geico Builder to handle our home renovation, including updates to the kitchen and bathroom, and the whole experience was fantastic. The team was professional, organized, and easy to communicate with from start to finish. They showed great attention to detail, stayed on schedule, and made sure everything turned out exactly how we envisioned it. Our kitchen looks stunning, the new bathroom layout is so much more functional, and the bedrooms feel brand new. It's rare to find contractors who combine quality work with honesty and reliability, but Geico Builders delivered on all fronts. Highly recommend them for any home remodeling project."

"Michael and team did such an amazing job on our bathroom remodel. They took our tiny, dysfunctional bathroom and turned it into a true master bathroom oasis in a short amount of time during the holiday season. When they had the space down to the studs, Michael sat down with us and discussed in detail the best possible use of the space and we couldn’t be happier with our final decision after going through the options. Michael was great at communicating and we still stay in touch to this day, which we truly appreciate. Great team who does great work and I will absolutely be giving Waters Construction a call for any and all future home renovations. I’ll let the pictures do the rest of the talking. "

"Our goal was to build a structurally safe garage storage loft. Juan and Julian were a great team to work with. They were very professional and organized- they gave us a quote and clearly communicated what the plan would look like from beginning to end. They guided us on the items that we needed to buy prior to starting the work in order to complete the project within the estimated time. They suggested modifications that were minor fixes but made the layout make more sense in terms of placement. Their crew finished a day ahead of schedule. They kept a clean work site and the quality of the results were great. I would gladly work with them on another home project in the future!"

FAQs for addition to existing structure building service projects in Antioch, CA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
