Jonathan is an absolute gem. He is so down to earth, smart, kind, and you can tell he cares about…read morewhat he is doing and about the customers. He has over 19 years of experience, started from one of the first companies to do this well out in the bay and then branched out to his own company, where it's clear he wants to commit to doing a good job for the customers versus just making a large profit. We got a quote from another company who was running a ton of ads and it was very clear after meeting and talking to Jonathan that the other company was in it for the money and the biggest job possible. Jonathan came in, sat down, explained ALL the issues. Drew pictures for us to understand better since it was clear that we were over our heads(esp since we spoke with the other company that made it seem like our house was a danger to be living in) then he continued to explain all of the structural components of our house and how it helps with the safety/etc(NONE of this was done by the other well known/IG ad pushing company). He took his time, went over different options, gave us rough estimates for both. Suggested and gave a list of people he suggested for soil reports(Within less than an hour of meeting us). Broke down costs and said YOU SHOULD NOT HAVE YO PAY MORE THAN THIS and laughed as I added extra for what if's. He was such a lovely person and his quote was WAY less than the other company who only gave us one very expensive option and then didn't even bother to send a full estimate (groundworks) I immediately wanted to work with him right after and plan to. Highly suggest him for any of your foundation needs. Save yourself time, no need to get other quotes from other companies and just go with him:)

From the first inspection to the final walkthrough, their crew was punctual, transparent, and incredibly knowledgeable. They explained every step of the process in plain language, gave a fair and detailed estimate, and delivered exactly what they promised. The quality of their work shows, my home feels solid, level, and secure again. They treated the property with care, cleaned up thoroughly, and made the entire experience stress‑free. In an industry where trust really matters, Golden Gate Foundation Repair absolutely stands out. Highly recommend them to anyone in the Bay Area who needs honest experts and top‑tier craftsmanship. Way better than a "competitor" who came by and all they cared about was upselling, not knowing I have a background in foundation of course. Now, I know who to recommend to family and friends!

Excellent service. I mean excellent…read more Rene (the owner) and his brother Alex were great to work with. They clearly know what they're doing and have a lot of experience. One thing that really stood out is that they noticed our old driveway had the wrong slope and that the approach up to the front porch was too steep. They corrected the driveway so it now has a proper slope toward the road and added a new step for us -- at no additional cost. That was not something we asked for, but something they caught. Everything was done exactly on schedule and exactly at the agreed price. No surprises. They also worked smoothly with another contractor we had on site at the same time. Before they left, the cleanup was immaculate. Several of our neighbors noticed how nice the driveway was looking. We are very happy with this. Competitive pricing, quality work, and easy to work with. I would highly recommend Rene, Alex, and Navarrete Concrete.

We are building a pool in our backyard, and needed a concrete contractor to pour a concrete decking all around the pool. After much deliberation and interviewing 5 different contractors, we hired Sierra's Concrete to do the concrete decking. They were the most responsive, had the best suggestions, and they had a large selection of photos of their previous work online. Their contracted work entailed: 1 - digging an 87 feet long, 6 feet deep French drain around the pool 2 - installing surface drains to collect rain water 3 - forming and pouring a roughly 1500 square feet deck according to our custom design Sierra's Concrete performed the work to perfection, ahead of schedule, and left the place cleaner than how they found it. It was a real pleasure to witness their performance. Their dedication, coordination, attention to detail and work ethic all shone during the 6 days that they spent here. I never witnessed any heated temper or frustration, the entire crew worked in perfect harmony in a relaxed but professional atmosphere. You could tell that they enjoyed working together and took great pride in their work. Cesar had excellent suggestions to improve on my design. I never had to ask him to do anything twice, and he was true to his word until the very end. His team worked relentlessly, barely ever taking breaks, moving from one task to the next without ever getting into each others' way. They left the site immaculate, even taking the time to pressure wash the driveway. They went above and beyond the call of duty at every step of the way. The end result of their combined effort exceeded our expectations. Cesar is a maestro, and he orchestrated everything with talent and brio. He and every member of his team are true artists. I would enthusiastically recommend Sierra's Concrete to anyone looking for quality drainage systems and beautiful concrete work. I could not have asked for anything better.

He and his crew were very talented. They used high quality materials and their craftsmanship was top notch. They took the time to do it right and did not use shortcuts. He was an excellent communicator and willing to answer any questions we might have. He assured us that he was not finished until we were satisfied with the results. He has many years of experience in masonry and it showed. We were constantly adding on as we found new areas that needed improvement. He was flexible and willing to work with us.
