It required thoughtful design, placement of lengthy sewer and water lines, extensive new electrical work, addition of a window, HVAC heat pump system, removal and replacement of new sheetrock, insulation, porcelain flooring, quartz countertops, appliances, fine carpentry including custom shelving, restoration of antique stained glass windows, tiling, and a versatile lighting system with spectrum-adjustable LED illumination.

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!"

"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. Oscar has earned my trust and will be my go-to contractor for any future projects. I highly recommend him to anyone in need of a reliable, skilled, and dedicated professional"

"Our experience is identical to what other reviewers shared. And yes, you should run from this company as fast as you can. Do not buy what Abraham shared that the payment must be made when the inspection is passed. Check the Business and Professions code yourself, the payment only needs to be made when the job is completed. It is very COMMON that the job is not even done or poorly performed even the inspection is passed. Here are the issues that multiple families including us run into with this company:: The project was delayed for over 9 months. No one manages the job. He often employs young men from his own Jewish community. They are enthusiastic but had no prior experience. The worse part is that they don't get paid. Two of them even set up a new construction business knowing Abraham will never pay them. Subcontractors can put your house on lien also. Many reviews you see on Yelp, Google, Angi are NOT genuine. Even the references are fake with hindsight, we were given 2 references. One reference shared the exact same accent as the PM. The other reference was initially happy with their work, but then reached out to us and shared a similar horror story with them like what we experienced. You will lose a lot of $$$ on materials as the subcontractors will somehow leave a thousand dollars worth of quartz at home. Maybe they want to compensate for the money Abraham owed them? Let me tell you, reordering materials is not fun."

"We were looking to remodel our kitchen or bath for a few years. We kept getting estimates from different companies and always felt the price was off or the person was not a good fit. Then, finally, we met Shai with Cal Green Remodeling. What a great guy! He is very upfront and honest about what we can expect in terms of cost and work flow. Because of his honest approach, we hired him. We felt he gave us the good and bad and how to resolve the bad as well. In the end, the process was fairly smooth, and the few hick-ups we had, for example, the city and their permit process, were well explained to us at the beginning, so we were ready. Our kitchen or bath looks amazing, and I plan to work with Cal Green Remodeling again. Thanks Shai!"

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