  • 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

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.

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.

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.
