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 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!"

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 my house. 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 can call structural engineers for chimneys. His quote was fair to me and you can't beat the warranty and financing. 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. The Chimney job is pending and again, I'm ahead of the curve and not waiting for it to get worse.

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.

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.

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.

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.

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!

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.

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.

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 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!

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
