Bay Area Underpinning
We used Bay Area Underpinning after getting a couple of different quotes for foundation settling. They ended up installing 31 piers around the perimeter of our house, including 4 in the crawlspace to minimize tearing out hard to reach areas.
Everyone that we dealt was excellent - very professional, friendly, knowledgeable and helpful. From Trevor who did the original estimate (who did not feel salesman-y whatsoever. in fact the first estimate he did, he recommended we don't do work and keep an eye on how it progresses). Hannah in the office was amazing and on top of everything and responsive. Jim did the engineering walk through and was very knowledgeable and hilarious. Our crew of Esteban, Luis and Rob who worked on our house was the best -- always on time, professional, courteous and left the worksite very clean at the end of each day. They even went out of their way to make sure our dogs had access to the backyard each evening. They kept us updated every step of the project, which lasted for 3 weeks.
I cannot recommend this company and this crew enough. It's a large, scary project but they put us at ease each step of the way. Now we have the peace of mind that our home will be forever stabilized.
