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

Jonathan Falcone was great to work with. He visited a couple times and walk through multiple options of design to rectify the sloping issues of our house. He was attentive and took multiple calls to help with the review and planning process. I would highly recommend to work with Jonathan! Looking forward to the project kicking off and the sloping foundation to be fixed!

This company gets a 10 out of 10 from me. From my initial consultation with Rick DeSoto to the work performed by foreman Raul, and his team Jonathan and Demareon, this was the best possible experience in working Bay Area Underpinning for the first time. The crew was professional and adjusted the leveling jacks (and even added a couple as was needed) with care and great attention. Pricing was very reasonable too. I'll never trust any other company to do this type of work at my home. 100% satisfied with the work and my interactions with the crew. A+ work performed = A VERY HAPPY CUSTOMER!!!

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.

We just bought a house and literally every single metal pier in the crawlspace was rusted out. Bay Are Underpinning came in and did an awesome job. Their inspector Aaron was super thorough in assessing the damage and explained everything in detail. Then, the repair crew of Eric, Jesus, and Andrew came in and knocked out the entire job in a day — a huge relief considering we had a ton of other work we need to get done before moving in. The work is not cheap, but they offer financing options and stand by their work, so I feel very good about the entire job.

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!

I had my foundation repaired and everyone who came to work was amazing. So helpful, polite and professional and with a great sense of humor. They completed the project a day earlier than expected and really worked with me on creative payments. I would recommend this company to anyone who has the misfortune of a cracked foundation. Super pleased!!!!!!
