Bay Area Underpinning Napa, CA – Other Services Offered

Foundation Movement Repair

For homes located on a hillside, one of the most common issues faced is foundation movement. This is usually indicated by signs like sloping floors, problems opening doors and windows, drywall cracks, etc.

Drilled concrete piers are an excellent solution to repair foundation movement and settling foundations. They are also suitable for building a deep foundation system for new construction projects.

Uneven Concrete Repair

Uneven concrete surfaces around your home can create trip hazards that can cause serious injuries to both residents and visitors. If someone gets hurt, you could find yourself facing an expensive lawsuit.

Polyurethane foam injection is perfect for lifting sunken or uneven concrete. Dime-sized holes are drilled into the affected concrete and then the foam is injected underneath the slab. The foam rapidly expands to fill the void, thereby raising the slab. This is a minimally-invasive procedure and your concrete surface will be ready to use within minutes.

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.

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.

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!!!
