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.

Thank you Bay Area Underpinning for saving the day! I was in a challenging and prolonged situation since going into contract with EagleLift for the stabilization/lift for my house. After a long permit process and continuously delayed start dates, I was informed that EagleLift had been acquired by Groundworks and I’d have to wait a few more month before any progress could happen. It was a deeply frustrating process but the EagleLift team was able to connect us with Bay Area Underpinning (another Groundworks company) who were able to take over and expedite the project. To my surprise, James T. from BAU reached out quickly and assigned a team to come to my house within a week! The team that ended up working on the house, specifically Ish, John and Abel were exceptional. They were diligent, knowledgable, friendly and deeply considerate. They are truly pros who knocked the project out in no time which was reassuring since I was nervous that this project was gonna stretch into the rainy season. My house feels so stable now (minimal cracks too) and the considerable slope is now practically nonexistent! Thanks a lot James T., Ish, John, Abel and the BAU team for taking really great care of us.

It turns out I have had Bay Area Underpinning out twice in 5 years to look at my foundation and unlike the other guys, Bay Area Underpinning told me my options and that I was still within industry standards and that I did not need the service. He went on to give me concrete examples as to when I would need to call him back out to do the job.

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.

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!

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.

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

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.

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.

1. Call Center ***** – they took the call after 6:00 PM and were extremely professional. Guy on the phone (sorry I didn't write is name down), was so kind and emailed confirmation immediately. 2. Pre-Visit Confirmation ***** – Email, text and phone calls to confirm the time and prep me for the visit. Incredible. Nobody is doing this right these days and BAU absolutely has it nailed down. 3. Estimator ***** – I wish I could offer more than 5 stars. Joe Le Bel is the most professional tradesman I've met in a long time. Others are good too, but Joe is the gold standard. He sat with me to ask what I was concerned about and what was important to my family. Who does that???? Oh yeah, Joe did. So comforting. Joe was professional and respectful of our space. Was careful to be conscientious about where he placed his gear, tools and instruments. Super clean going under the house without tracking dirt and debris back into the house. (The inspectors from HomeGuard could definitely take notes on this!) Then, once Joe finished, he sat down with us and talked us through all the different aspects off his inspection. What an extremely positive interaction. I would 100% recommend BAU and Joe. Can't get any better than this. Thanks BAU for a great culture of excellence. Thanks Joe for being such a good human and professional!

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.

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

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.

I had Joe inspect the crawlspace of my home, and I couldn't be more satisfied with the experience. First off, he did the inspection for free, which is rare these days! Joe was professional, punctual, and thorough in his inspection, explaining everything he found in a way that was easy to understand. He took the time to ensure I knew what was going on beneath my home and didn't push any unnecessary services. I highly recommend him for anyone in need of an honest and detailed inspection. Definitely a 5-star experience!"

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!!
