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!"

"Ben and his team completed work on my condo and I could not be more pleased with the results.

Ben, Marcus, and Pete were prompt, professional, and very considerate of my time and space. Of note is Ben's candor when it came to design ideas, and expense.

FAQs for second story addition building service projects in Napa, CA

For many homeowners, building up is worth the expense because it provides the extra bedrooms or living areas that can’t be accommodated within the existing footprint. A larger, updated home often commands a higher resale price, recouping a sizable share of the project cost while allowing you to stay in the neighborhood you love. Run the numbers with a real estate agent and contractor to ensure the expected return and day-to-day benefits align with your goals.

Whether it makes more sense to build up or out depends on your lot, budget, and local code. Building up preserves yard space and involves less foundation work, but you may need to vacate the home during construction. Building out avoids staircases and can proceed while you stay put; however, it encroaches on the yard and may face setback limits. Compare both options with your contractor before making a decision.

A structural engineer will first inspect the existing foundation for cracks, footings, and load capacity. Depending on the findings, the crew may pour new concrete footings, install steel or concrete piers, add reinforced beams, or tie additional rebar into the slab. These upgrades redistribute the weight of the new floor and bring the structure up to code. Your contractor will outline the specific reinforcement plan and timeline once the engineering report is complete.
