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 used Geico Builders for our bathroom remodel. We collected a few quotes, and we felt like the quote for the value was the best. I appreciated the clear scope and payment schedule. We started with a tiny bathroom and had plans to remove a couple of walls to make it larger. Leading up to demo day, our project manager Mila and the team pulled permits and helped us understand which finishes/materials we needed to order. I had a clear idea of our design vision, so I didn't need a lot of assistance there, but I found the 3D rendering helpful to see. Our project took a little over 5 weeks. The foreman David and crew did a great job. I was many specific requests, and I felt like David always did his best to incorporate my requests. We had a few hiccups, as with any project. We ran out of tile, which caused a small delay. The crew also misplaced some of our shower fixtures and we had to reorder them. The team was able to cover the cost of these, which I appreciated. I liked how we had a group to stay on top of updates. There were times when I would have liked more communication regarding the crew's schedule, delays, etc. but overall, I felt like my questions were always answered. Love my new bathroom, thank you."

FAQs for second story addition building service projects in San Francisco, 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.
