  • Concrete Lifting – Uneven sidewalks, patios, driveways, and other concrete surfaces are a trip hazard. The good news is most uneven concrete slabs don’t require removal and replacement. We can easily raise them in just a few hours using polyurethane foam injection.
  • Drilled Concrete Piers – Drilled concrete piers are a common repair solution for homes built on hillsides that are experiencing lateral movement due to soil creep.
  • Helical Piers – Lightweight foundations that are settling can be raised and stabilized using helical piers. Helical piers are excellent for supporting foundations built on problematic soil.
  • Crawl Space Repair – A sinking crawl space can often be repaired using screw jacks. In most cases, the existing pier blocks are in great shape. So, we just remove and replace the posts or the damaged screw jacks. At that point, the floor can be lifted.
  • Foundation Repair – Bay Area Underpinning offers foundation repair using push piers, helical piers, slab piers, and more. Contact us today for a free foundation evaluation

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.

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.

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

Foreman Andrew is incredible and a leader. We hired BAU to perform a whole house underpinning job from December 2022-March 2023. Our recently purchased 1950's home sat on expansive clay soil and had been settling for decades. The project was a big job and complicated by the winter rains that occurred throughout many days of the project. Andrew was extremely professional, knowledgeable about every aspect of the job and managed the entire project class and skill.He communicates very effectively and is transparent to assuage any concerns that we had on the project. He also shows up earlier than anyone, and works the entire day, rain or shine, in the mud and trenches with his team. This leadership was impressive. Since the completion of our project, he has remained available and came out to make some minor adjustments promptly and free of charge. Without any hesitation, I would entrust BAU to do my foundation work with the demand that Andrew lead the project. Thank you Andrew and your crew for a job well done.
