Foundation Repair Services in Mill Valley

- 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

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 recently hired Bay Area Underpinning to underpin my home and my experience from start to finish was seamless.Jordan Christle, the lead foreman and his team were exceptional. They were communicative, polite and professional at all times. They were happy to answer any questions that I had prior to and during the process of underpinning my home and were quick to provide clarification and explanations to any of my concerns that I had during the job. Jordan provided extensive quality checks at all phases with his crew to ensure the best outcome for the home owner.The team’s knowledge base about their field was remarkable as they were able to come up with quality solutions that we could visibly see.I recommend Bay Area Underpinning without reservation and will continue to recommend them to anyone who should need their services.

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.

Bay Area Underpinning is OUTSTANDING!! Cody, Andrew, Francisco, David and their underpinning and concrete teams did exceptional work installing underpinnings to stabilize our house, then replacing the concrete patio that had to be removed to do the stabilization. Everyone on the teams were efficient, courteous, highly skilled, and thorough. I cannot recommend Bay Area Underpinning highly enough- through each step of the process, from the initial assessment and work quote, to the work and follow-up itself, the staff and crews of Bay Area Underpinning ensured that I was informed, reassured, and we’ll take care of. They were thoughtful about doing their work efficiently and cleaning up after the work was completed. I cannot recommend them highly enough!

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.

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.

I can’t praise Bay Area Underpinning enough! Everything from their support team, to their customer service, and the quality of their work has surpassed my expectations. I’ve used other foundations companies in the past and they weren’t great for many reasons – Bay Area Underpinning has none of the challenges I’ve experienced elsewhere, and massive positive upsides! Would highly recommend!

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