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 hire Geico builders for our kitchen remodeling project, and I'm happy to share my experience: Working with Zaya and Geico Builders was a great decision. They were professional, friendly, and easy to work with. From the start, the process was smooth and efficient. The craftmanship of my remodel kitchen and attention to detail were exceptional, and the end result far exceeded my expectations. From the design phase to completion, their communication was excellent, and I felt completely at ease with them working in my home. The design solutions completely transformed my kitchen, making it both functional and beautiful. I highly recommend Geico Builders for anyone looking for a stress-free and satisfying remodeling experience."

HI!, my name is Irving Rodriguez, and I’m a licensed contractor with over 40 years of experience. I specialize in high-quality remodeling and property services designed to enhance the beauty, functionality, and value of your home. Tailored to your vision and needs. Trust and Reliability: Decades of experience with satisfied homeowners.

We can schedule a consultation to review your goals and provide a detailed estimate. Thank you for your time, and I look forward to helping you make your home even better!

"So they’ve constructed many different things in my mother’s home now. From bathrooms to and a series of home improvement projects—most notably a complete bathroom remodel, as well as various upgrades and repairs throughout the house—and the experience exceeded all expectations. From the very beginning, the professionalism and attention to detail stood out. They treated our home as if it were theirs, ensuring that every fixture, tile, and finish was executed with precision and care. The bathroom transformation was truly stunning—sleek, modern, and remarkably functional. What impressed me most was the seamless coordination of multiple trades, and how effortlessly he managed the timeline while maintaining an exceptional standard of quality. Not to mention the very affordable pricing! Beyond the bathroom, he tackled several other improvements—drywall repair, custom carpentry, tiling, and fixture installations—all done flawlessly. He brought creative solutions to the table, respected our vision, and always kept us informed throughout the process. Cleanliness, punctuality, and craftsmanship were consistently top-notch. If you’re looking for a contractor who combines integrity, skill, and artistry, look no further. I wouldn’t trust anyone else with my home. This is a rare find in today’s market, and I can’t recommend them highly enough."

"Oscar truly stands out as a contractor who cares deeply about his clients, and that’s exactly how he made me feel. I reached out to five different contractors to assess my bathroom and offer ideas, but my experiences varied significantly. Some were overly sales-driven, others dismissed my ideas entirely, and one didn’t even follow up with an estimate. Oscar, however, was a breath of fresh air. He arrived on time, listened attentively to my ideas, and offered thoughtful suggestions. He was highly collaborative with the other workers on site, making sure everything was well coordinated. Oscar's expertise in the industry is evident, and he’s exceptionally creative when it comes to problem-solving. When he identified additional challenges during the project, he took the time to offer practical solutions, demonstrating his commitment to delivering the best result.

Second story addition building services FAQs

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.
