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!

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.

Working with BayArea Underpinning was a great experience. Ron Hobbs was professional and so easy to work with. Their crew especially Mike was detailed and on time. Very honest company. They rebated me back money on something that I would have known about but Mike was honest enough to tell me. Very impressed. Call them they did a great job!

Bay Area Underpinning is THE company to use for foundation work. Aaron, and his crew, were incredibly professional from start to finish. The team kept the work space clean and tidy, communicated well, and updated me as timelines were solidified. They were always on time and ready to maximize their output for the day. I would recommend them in a heartbeat.

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.
