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.

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.

Bay Area Underpinning is THE company to use for foundation work. Aaron, and his crew, were incredibly professional from start to finish. The team kept the work space clean and tidy, communicated well, and updated me as timelines were solidified. They were always on time and ready to maximize their output for the day. I would recommend them in a heartbeat.

I recently hired Bay Area Underpinning to underpin my home and my experience from start to finish was seamless.Jordan Christle, the lead foreman and his team were exceptional. They were communicative, polite and professional at all times. They were happy to answer any questions that I had prior to and during the process of underpinning my home and were quick to provide clarification and explanations to any of my concerns that I had during the job. Jordan provided extensive quality checks at all phases with his crew to ensure the best outcome for the home owner.The team’s knowledge base about their field was remarkable as they were able to come up with quality solutions that we could visibly see.I recommend Bay Area Underpinning without reservation and will continue to recommend them to anyone who should need their services.

The team I worked with at BAU was great. I hired them to repair some minor vertical and horizontal foundation cracks that were found in a recent general home inspection. Everyone who came out was upbeat, professional, punctual, thorough, and highly detailed. Hunter came out first to check the entire foundation and give a free estimate. They then split the work up into two dates, and each crew was great. Michael and James came out first for the initial round, and then Alexander and Gabe came out to wrap up the last few areas. The guys were always on time, which is greatly appreciated. Both repair teams also did their own additional checks of the surrounding areas, also greatly appreciated. They were also able to provide before and after pictures, and were respectful of the property.

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.

Our house is 85 years old and has some cracking on the stucco, so I called for a free inspection to see if the problems were something we need to be concerned about. Daniel, our inspector, was prompt and friendly and explained everything he was doing and seeing as he took measurements and inspected the foundations. He said that while there are things we can do for earthquake retrofitting (and he did recommend a separate company for that if we wanted to do it) our problems were mostly cosmetic and nothing to worry about. He also took his measurements to be scanned in at his office and kept on file so that we can have him back out for another inspection in the future to compare, again, purely at our discretion. He was respectful, friendly, and straightforward and answered all of my questions. I'd definitely recommend them.

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.

I had my foundation repaired and everyone who came to work was amazing. So helpful, polite and professional and with a great sense of humor. They completed the project a day earlier than expected and really worked with me on creative payments. I would recommend this company to anyone who has the misfortune of a cracked foundation. Super pleased!!!!!!
