Foundation Repair

Are the floors in your home uneven? If so, you need to have your foundation inspected by Bay Area Underpinning, the foundation repair experts in Vacaville, CA.

One of the most popular methods we use to repair a sinking foundation is foundation underpinning. In most cases, only a portion of the foundation is likely to have settled, which means it is sufficient to only work on the problem area. Resistance or helical piers will be installed along the foundation by making small excavations. The foundation will then be lifted with the help of a synchronized hydraulic lifting system.

Concrete Lifting

Concrete slabs settle for various reasons, including poor drainage, poor compaction, and invasive tree roots. In Northern California, concrete slabs often settle due to clay-rich soil that expands and shrinks due to moisture. Fortunately, your sunken concrete slabs can be liftedbusing polyurethane foam injection – a simple, minimally-invasive procedure.

Small holes are drilled in the affected concrete, and then polyurethane foam is injected under the concrete slab via ports placed inside the drilled holes. The foam starts reacting, filling the void beneath the concrete and lifting the slab.

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.

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 had a great experience with Bay Area Underpinning. They fixed my foundation, which was a substantial job, in a matter days, and did all of the engineering and permitting at a very fair price. I cannot say enough good things about Tyler, Angelo, and Louise, who did all the hard work. They were on time each day, very diligent, and patiently answered all of my questions. Then, when the job was finished, they cleaned the work area and left it in a better condition than they found it. That was awesome, and tells you what you need to know about these guys and the company. I couldn't be happier.

Within a few months of buying our first home, we noticed some troubling signs: bedroom doors swinging open or closed on their own, “bubbles” and creaks in sections of the newly renovated floors, and significant cracks splitting the concrete in our garage. Although two general inspectors assured us that our house was level, we reached out to Bay Area Underpinning (BAU) for a more detailed assessment—and we're so glad we did! Inspector Christopher Murray conducted a meticulous inspection with radar equipment. While technically our house was level, Christopher uncovered that our foundation was sinking by inches in multiple areas, explaining the issues we were experiencing. Though the news and associated repair cost were a bit daunting as new homeowners, Christopher’s knowledge, professionalism, and clear answers to all our questions reassured us that we were in good hands. With confidence, we decided to proceed with BAU for the repair. Fredy Mora and his crew did exceptional work with the demo of the old concrete slabs and the prep for lifting, working quickly and efficiently. Fredy’s positive attitude made the process smooth, and his team was thorough and dedicated from start to finish. A special thank you to our lift project manager, Kevin Gaeden. Kevin was an outstanding communicator, keeping us fully informed and addressing every question promptly. His attentiveness made a huge difference throughout the project, and we felt reassured every step of the way. Esteban Ibarra, a crewmember on the lift team, also did superb work, handling the hands-on details with skill and care. Both Kevin and Esteban even went above and beyond, taking time to fix a jammed bedroom door that had shifted with the house lift. While foundation issues are never easy, we couldn’t have asked for a better team. We’re incredibly grateful to Bay Area Underpinning for their expertise, professionalism, and exceptional service. Thank you, BAU!

I would recommend them in a heartbeat.

We used BAU to install piers and screw jacks to level our home. Really pleased with the entire process. The communication was stellar and the foreman made sure we understood each step as it was happening. The whole crew was professional, polite, punctual, and very neat. Each day they left the job site nice and tidy. The overall result is amazing. Our floors are level and the house looks great. Would highly recommend for any foundation/leveling needs.

BAU did a great job on my ADU that had a serious moisture problem that was causing the building to deteriorate. I couldn't remove the tile without replacing it all at a large expense so they did the whole job in a very cramped crawl space. The guys they sent out were great and finished with everything in one day!!!

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

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 hired BAU to underpin our foundation. After extensive research I learned that BAU does the best work and at reasonable prices. Jordan lead the crew that did the work on our house, and he was a joy to work with and we really trusted him and his team to take care of us. I am really glad we hired BAU, and we are happy to have our hillside home properly secured for the future!

I recently scheduled an inspection after concerns around my foundation and worked with Jim Rivera on my home. Jim was super helpful and knowledgeable in assessing the severity of my foundation issues, while also assessing other parts of the home that might be contributing to potential damage in the future. I was surprised how helpful he was in helping me understand different scenarios, planning for near-term/long term fixes, and putting my mind at ease over the foundation issues. I'd definitely recommend working with Jim and his team!

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

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.
