The permiting process took a long time, but that's not their fault. The cost was very high but competitive with another contractor.

Last week, my car cut off while exiting the highway in Dixon, and I was stranded in a dangerous spot. Fortunately, your employees who were driving a Bay Area Underpinning truck, Erick Baez, Jesus Vallegomez, and Wesley Almaza stopped to help. They worked hard to try and troubleshoot my car and even pushed it out of the street to a nearby gas station while I waited for AAA. Their professionalism, kindness, and respect were incredible. I'm so grateful for their assistance, especially since I’m a woman who was alone in an unfamiliar area in the evening. Thank you, gentlemen!

We have a long horizontal crack on one side of our external wall. Although I had serious concern there is a foundation issue, Micheal Silva from Bay Area Underpinning came in and did thorough inspection with detail measurements and drawing and concluded that we don't have a foundation issue with great honesty. He also further inspected from the crawspace entrance and the stucco to let me know what's the potential issue outside the foundation concern. His professionalism, diligence, honesty, patience and extra step to help in figuring out the problem are truly appreciated.

Review for Tyler and Luis who came and knocked out the piers and slab leveling in short order. Super professional, clean, accommodating, showed up and left on-time and stayed on task so much so that they were able to shave a day off the assumed schedule. Was a pleasure to work with these guys.

When we had our 1960s home underpinned, the consultant arrived on time to give us a quote. He gave us different options for work to be done and had solutions to cutting cost on things that weren't absolutely necessary. The work was done within a week. All of the workers were professional. Something that stood out the most was the way the workers communicated with each other. They weren't your typical construction crew in this sense. They were very kind to each other and supportive of each other, even when they were in a difficult situation. This isn't common in construction. As for the cost, it was what we had expected and we don't have any complaints. Our house is level now and doesn't feel like we're drunk walking in areas that were previously sagging. There's a reason Bay Area Underpinning is #1 in the area. Would recommend, even if they aren't the cheapest- they get the job done right.

I will sleep much better tonight. I noticed a crack in my foundation and called Bay Area Underpinning. Hunter came out and walked the entire property and went underneath my house. He identified one other issue that I knew about besides the crack and told me they could fix that too. I had no idea you can call structural engineers for chimneys. His quote was fair to me and you can't beat the warranty and financing. Today Jesus Villagomes and Erick Baez came out and fixed the crack, they also looked around underneath and reassured me AGAIN that my house was in good shape. Because I caught it early they were able to fill the crack and then add a carbon fiber exposy seal. They also sealed the crack from the outside, even though they had already filled it in under the house. They were professional, answered all my questions, no matter how many and honestly were just pleasant to work with. They also explained my maintenance plan so I knew what to expect. I would absolutely recommend this entire team, to stay professionally kind in high heat is amazing. The Chimney job is pending and again, I'm ahead of the curve and not waiting for it to get worse.

Had Bay Area Underpinning come out for a free estimate to check my foundation. They verified the appt 2 days before along with day of, I got a link as to where the technician was and he was on time. Ronald was very professional and informative. He was able to answer all my questions in a way I could understand and I got a copy of all the findings. Would definitely recommend for anyone needing an inspection.

We just bought a house, and literally every single metal pier in the crawlspace was rusted out. Bay Are Underpinning came in and did an awesome job. Their inspector Aaron was super thorough in assessing the damage and explained everything in detail. Then, the repair crew of Eric, Jesus, and Andrew came in and knocked out the entire job in a day — a huge relief considering we had a ton of other work we need to get done before moving in. The work is not cheap, but they offer financing options and stand by their work, so I feel very good about the entire job.

Everything looks good after the work was done. I can finally close my bathroom door. I appreciated the fact that the foreman Erick Baez, went over what was done as they were done. I also appreciated that the two installers Manny Erickson and Jesus Villagomez also communicated with me after they were done to reassure that they did a proper job installing the jacks. Very good to know how the process was going. Great job.

Brandon and his crew were wonderful to work with. We had pretty extensive movement in our foundation, and Brandon was knowledgeable and took the time to carefully explain all of our options and how each would look. He and his crew were communicative and professional. Our biggest fear was that our new kitchen granite counters would crack in the lifting, but Brandon and his crew were extremely mindful of the situation, taking extra care and nothing cracked. Thank you, Brandon!

I recommend Bay Area Underpinning because the agent they sent to inspect my crawlspace told me the truth. He could have tried to sell me work I didn't need, but instead, he explained to me why he thought I didn't need it. I wish all contractors were this honest! Call them for an inspection. You can trust them. I only wish I had a job for them! Randy Sonoma

We had a fantastic experience with Bay Area Underpinning, lifting our foundation four and a half inches of our old 1958 Napa house! After careful review of several contractors, we chose Bay Area Underpinning and so glad we did! The entire process was smooth from the sales engineer estimate to the completion of the job, the communication was outstanding all along from day to day and ourblift was a big job with a full week of labor intensive work. I especially want to thank Foreman Cody Summers, Co-Foreman Ken Hamlin, and Installer Nikolas Klein for their outstanding work and customer service! They are the best and ensured that I was happy with the progress and completely satisfied. I also want to thank Superintendent Kevin Gaeden for his outstanding communication! My wife and I are completely satisfied and happy with the outcome! It was a great choice with great value after the job was complete! We would hire Bay Area Underpinning all over again! Thank you very much for a job well done!

I requested a free estimate of how much it would cost to re-level our brick patio that had began settling years ago due to a failed retaining wall. This wall was replaced last year, hence the desire to do the brick/concrete slab leveling using Bay Area Underpinning's Polyrenewal process that can literally raise a slab. The certified field inspector, Chance Danner, was very thorough in his evaluation of what was needed, and the entire presentation was well organized, clearly laid out, professional and the pricing was reasonable. Chance explained how they would do the job in our patio, and backed it up with visuals on their Polyrenewal system. Although we decided to wait to do the job until after we took care of several other major projects, we would definitely recommend Bay Area Underpinning to anyone.

Within a few months of buying our first home, we noticed some troubling signs: bedroom doors swinging open or closed on their own, “bubbles” and creaks in sections of the newly renovated floors, and significant cracks splitting the concrete in our garage. Although two general inspectors assured us that our house was level, we reached out to Bay Area Underpinning (BAU) for a more detailed assessment—and we're so glad we did! Inspector Christopher Murray conducted a meticulous inspection with radar equipment. While technically our house was level, Christopher uncovered that our foundation was sinking by inches in multiple areas, explaining the issues we were experiencing. Though the news and associated repair cost were a bit daunting as new homeowners, Christopher’s knowledge, professionalism, and clear answers to all our questions reassured us that we were in good hands. With confidence, we decided to proceed with BAU for the repair. Fredy Mora and his crew did exceptional work with the demo of the old concrete slabs and the prep for lifting, working quickly and efficiently. Fredy’s positive attitude made the process smooth, and his team was thorough and dedicated from start to finish. A special thank you to our lift project manager, Kevin Gaeden. Kevin was an outstanding communicator, keeping us fully informed and addressing every question promptly. His attentiveness made a huge difference throughout the project, and we felt reassured every step of the way. Esteban Ibarra, a crewmember on the lift team, also did superb work, handling the hands-on details with skill and care. Both Kevin and Esteban even went above and beyond, taking time to fix a jammed bedroom door that had shifted with the house lift. While foundation issues are never easy, we couldn’t have asked for a better team. We’re incredibly grateful to Bay Area Underpinning for their expertise, professionalism, and exceptional service. Thank you, BAU!

Jonathan Falcone was great to work with. He visited a couple times and walk through multiple options of design to rectify the sloping issues of our house. He was attentive and took multiple calls to help with the review and planning process. I would highly recommend to work with Jonathan! Looking forward to the project kicking off and the sloping foundation to be fixed!
