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.

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.

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.

I called in Bay Area Underpinning for foundation work. They were wonderful answering my many concerns, I received prompt return calls, the work was completed within an appropriate time frame, and the best thing he stayed with the estimate to the dollar. I loved the engineer, time frame, and minimal damage repair. I didn't know how my house was going to respond and even the marble and windows handled well. Unfortunately I didn't get the exact lift I wanted in the office even though they tried their hardest. My advice — call them when the problem first arises and the outcome and the house will lift with ease. I definitely recommend BAU. Because I live on a hill one pillar had to be covered – done. I also had a French drain installed to divert the water which was recommended. Thank you
