We recently had foundation work completed. The crew was on time every day and worked hard to keep a very dirty job and their traffic through the house to a minimum. The crew chief, Robert Busch, was amazing. Telling us what was planned for the day, any unforeseen problems, and giving us a recap of what was completed daily. We could not have had a better experience with his communication and hard work. Everyone was respectful and friendly. I also thought that the evaluation and estimate experience was positive. Jim communicated clearly and we never felt that work being suggested was unnecessary. He explained clearly and showed us pictures of what was going on under the house.Hope we never need them again, but would use them in a flash.

BAU did a great job on my ADU that had a serious moisture problem that was causing the building to deteriorate. I couldn't remove the tile without replacing it all at a large expense so they did the whole job in a very cramped crawl space. The guys they sent out were great and finished with everything in one day!!!

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. 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 call structural engineers for chimneys. His quote was fair to me and you can't beat the warranty. 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.

We had an amazing service experience from David and Rico of Bay Area Underpinning. David and Rico were very professional, super nice, and worked hard on leveling my floor. They arrived on time after giving me a call earlier to let me know they are on the way. They put on shoe covers to make sure my floor is protected. They patiently listened to my inputs and addressed my concerns with competence and great care. And they would not leave until all the uneven floor areas are fixed to my satisfaction. This team deserves my 5 star rating.

Had BAU take care of a chimney that was leaning away from my home, fix my front door which would jam at times of the year and relevel my floors. This was my second time working with BAU who installed screw jacks and leveled my floors several years ago. This time, Juan took a look at the problem areas, took measurements, made recommendations that fit my needs and budget and answered all my questions. Gonzalo and team came to work on my property. They worked quickly to install piers under the chimney and in the crawl space. They put tarp down to keep the house clean in the areas they needed access and cleaned up after themselves each day on the job. They answered my questions and throughly explained the problems and solutions they would implement to level the floor. Overall, I'm pleased with their work, being on time each day, and communication skills and would recommend.

This company just finished installing 5 piers for my house. They did an outstanding job!! Jacob was in charge of the project and he informed me on every step of the project. The team was very professional and courteous. They cleaned everything up to perfection. If you need foundation work, this is the company. The cost was reasonable as well. Highly recommend!!! Thank you Jacob, job well done!!

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!

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.

We had Daniel come out to take a look at our foundation to see if there were any issues that needed to be fixed under our home (a second opinion). After our first inspection we were told there were numerous issues that needed to be fixed that surely would have cost us thousands. We were considering the Earthquake Brace and Bolt program so the first inspection was a recommended foundation company through the EBB program. Daniel came out and took his time measuring the house on the exterior and interior. He was super meticulous and took settling measurements and also went under our home and took photos of the foundation. He sat with us after and explained everything to us. Turns out our foundation is stable and not needing any work. Daniel was super professional and knows his trade very very well. He was very honest. I now have a company I would call back in a heart beat if I needed to have any foundational work done. I will also recommend them to any neighbors that need this kind of company. The estimate was free as well and Daniel also had no hesitation crawling under the house on a 101 degree day to check things out. 5 star company here. Do not hesitate and call them! -Nicole San Ramon

I recently scheduled an inspection after concerns around my foundation and worked with Jim Rivera on my home. Jim was super helpful and knowledgeable in assessing the severity of my foundation issues, while also assessing other parts of the home that might be contributing to potential damage in the future. I was surprised how helpful he was in helping me understand different scenarios, planning for near-term/long term fixes, and putting my mind at ease over the foundation issues. I'd definitely recommend working with Jim and his team!

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.

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
