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.

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!!

We recently purchased a home in San Jose. In the report it stated that our home was fine and no foundation issues were noted. Upon moving in my wife noticed some cracks started to appear on the walls around the house. We contacted Bay Area underpinning to have them come and inspect our house. A couple of days before our appointment, Jim Rivera gave us a call to confirm the day and time of the appointment. This was the first positive experience we had with Jim and BAU. On the day of the appointment Jim called to let us know that he was 30 minutes away and showed up right on time. Once he arrived he listened to the issues we were noticing and then he went to work. He brought in some hi-tek tools and explained to us what the readings meant. Jim was extremely thorough and personable. He clearly has a lot of knowledge and showed us a bunch of photos that he took while he was in our crawlspace as well as photos of some exterior things that he noticed. Overall he said our home was in great condition with only minimal issues that we should address. He was very patient in answering all of our questions and provided us with a quote when he was finished. We were pleasantly surprised that the cost was very reasonable and comes with a lifetime warranty. We will be giving our business to Jim and Bay Area Underpinning. As a new home owner we were terrified of what the cost could be to fix our home. Jim really helped us understand what was going on and we would suggest that anyone who is having similar foundation issues like ours, we highly recommend that you should call Jim Rivera and Bay Area Underpinning.

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.

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.

I can’t praise Bay Area Underpinning enough! Everything from their support team, to their customer service, and the quality of their work has surpassed my expectations. I’ve used other foundations companies in the past and they weren’t great for many reasons – Bay Area Underpinning has none of the challenges I’ve experienced elsewhere, and massive positive upsides! Would highly recommend!

Several months ago, I noticed that doors in my house were no longer closing and latching. Specifically, my front door no longer locked completely. Once I got it fully locked I could no longer open my front door anymore, so I knew I had foundation issues. I called Bay Area Underpinning to come look at my foundation and do some measurements. We discovered that my front living room was sinking approximately one and a half to 2 inches. The crew, Lance Sladek, Jake Hall, and Eddie Shaw, crawled under my house and dug 30 to 40 foot holes in the ground to install piers that would lift my foundation. These gentlemen worked in very cramped dirty conditions in 90-100° weather. I was extremely happy with their work and their dedication to doing the job correctly. My after the foundation lift, my front door as well as several other doors in my home were able to close and latch again.

Foreman Andrew is incredible and a leader. We hired BAU to perform a whole house underpinning job from December 2022-March 2023. Our recently purchased 1950's home sat on expansive clay soil and had been settling for decades. The project was a big job and complicated by the winter rains that occurred throughout many days of the project. Andrew was extremely professional, knowledgeable about every aspect of the job and managed the entire project class and skill.He communicates very effectively and is transparent to assuage any concerns that we had on the project. He also shows up earlier than anyone, and works the entire day, rain or shine, in the mud and trenches with his team. This leadership was impressive. Since the completion of our project, he has remained available and came out to make some minor adjustments promptly and free of charge. Without any hesitation, I would entrust BAU to do my foundation work with the demand that Andrew lead the project. Thank you Andrew and your crew for a job well done.

I recommend Bay Area Underpinning for an important reason: honesty. After careful inspection, their agent, Richard, told me the truth, which was that my crawlspace was fine, that I had no problem with moisture or settling. And then he took the time to show me why. He could have tried to sell me on doing a lot of work, but he didn't. This kind of honesty is impressive! Call Bay Area Underpinning to inspect your crawlspace. You can trust them. If they say it needs work, hire them to do it. I am almost sorry I couldn't!

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.
