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

We were told about moisture under our home so we decided to schedule a foundation inspection and our inspector was Chris Murray was incredible! Called to confirm the day before, and the morning of communicated his ETA. He came in and was extremely nice and professional. He explained everything he found afterwards and was honest about our solutions and cost. We have an extremely small crawl space so he was unable to book us for something within his company but he continued to look into other options for us. It is refreshing to have someone come out and be very truthful about our options!

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!

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.

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.

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

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!

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 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!

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.

We had Jonathan Falcone assess the foundation and sloping issues of our home, and he's been incredibly accommodating throughout the process. He thoroughly explained the necessary work and has been attentive and helpful with the quoting and planning stages. We're very satisfied with the experience so far and we are eager for the foundation and underpinning work to begin soon.

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.
