Get matched with top foundation repair specialists in Mill Valley, CA

"Within a few months of buying our first home, we noticed some troubling signs: bedroom doors swinging open or closed on their own, “bubbles” and creaks in sections of the newly renovated floors, and significant cracks splitting the concrete in our garage. Although two general inspectors assured us that our house was level, we reached out to Bay Area Underpinning (BAU) for a more detailed assessment—and we're so glad we did! Inspector Christopher Murray conducted a meticulous inspection with radar equipment. While technically our house was level, Christopher uncovered that our foundation was sinking by inches in multiple areas, explaining the issues we were experiencing. Though the news and associated repair cost were a bit daunting as new homeowners, Christopher’s knowledge, professionalism, and clear answers to all our questions reassured us that we were in good hands. With confidence, we decided to proceed with BAU for the repair. Fredy Mora and his crew did exceptional work with the demo of the old concrete slabs and the prep for lifting, working quickly and efficiently. Fredy’s positive attitude made the process smooth, and his team was thorough and dedicated from start to finish. A special thank you to our lift project manager, Kevin Gaeden. Kevin was an outstanding communicator, keeping us fully informed and addressing every question promptly. His attentiveness made a huge difference throughout the project, and we felt reassured every step of the way. Esteban Ibarra, a crewmember on the lift team, also did superb work, handling the hands-on details with skill and care. Both Kevin and Esteban even went above and beyond, taking time to fix a jammed bedroom door that had shifted with the house lift. While foundation issues are never easy, we couldn’t have asked for a better team. We’re incredibly grateful to Bay Area Underpinning for their expertise, professionalism, and exceptional service. Thank you, BAU!"

"We were in need to Remodel our Bathroom due to leak from the pipe in between two Bathrooms and change out the plumbing of our house from galvanized steel to copper, upgrade drain to ABS pipes. Geico Builders crew had an immediate availability to solve our issues. Mila was assigned to our project as a project manger. The communication of the project manager was outstanding as well as guidance on what has to be purchased for completing our beautiful Bathroom. Once the water leak was discovered and the subfloor damage was assessed. A repair plan was quickly in place for the leak. Plus a plan to restructure and build a stronger subfloor. Overall, Mila and Supervisor Ruiz and their team were very excellent at staying on schedule and completing the project with quality workmanship. Overall we are very happy with our beautiful new bathroom. Our renovation project was completed on time and the new look absolutely met our expectations. Our main expectations/requirements were a regular shower pan, the shower walls and the flooring, all done with quality porcelain tile. Adding a shampoo niche and 2 safety grab bars in the shower area. Plus the bench which I am so happy with. All of these items were installed with attention to detail and with quality workmanship. Thank you Geico Builders for your professionalism and hard work we are truly Happy with everything you had done to our house and looking forward to work with you for our new project which is going to be Kitchen Remodeling by next year."

"I recently hired Just Stamping Concrete for a landscaping project, and I must say that I was blown away by their work. Their team is highly skilled and knowledgeable, and they truly transformed my outdoor space into a beautiful oasis."

"Excellent service by Cortez Bros. They came and repaired a slope issue and fix my patio. Created new trench, and finish the whole thing just the way I wanted. Highly recommend their service."

"Excellent work. Very responsive with the original job estimate that was a very fair price. They know what they are doing. Showed up on time and finished early. the job was beautiful."

"We found this company through Home Advisors when we needed extensive repair work on our very large front deck that included removal of several layers of the old Deck 70 coating and decayed plywood, rebuilding the substructure, and eventually applying a waterproof membrane over it before installing a new topcoat. To do this, portions of the stuccoed facade of our house and the deck railing had to be removed to make room for new flashing all around. After we came to an agreement with Dan Betyordekom of I Construction to do the work, we braced ourselves for the disruptions and turmoil such a project typically inflicts on an active household (this was not our first such rodeo), dreading the inevitable delays that seem to be part of any construction work. Today, merely 10 days after we signed the contract, we look out on our splendid new deck, which, even according to the building inspector, reflects excellent work. Don's tireless crew showed up on time every day, worked meticulously and professionally, took no shortcuts, cleaned up thoroughly at the end of each day, and went beyond our expectations in every aspect. When they replaced the portions of the stucco and deck railing they had removed, they didn't just paint the replaced portions-they painted the whole house wall and railing... Throughout the work, Dan was in constant contact with us to ensure that our normal routines were not affected by the work, and even made sure that the deck would be finished and usable for a baby shower we had scheduled for our son and his expecting wife. The deck was finished in time, and the party was a blast!"

"Oak called 2nd but came next day/ UN-prepared to do either repair or water test (requested on phone) or even replace with ready new ADA toilet that the lying receptionist booker said they have “some in stock and if not he will show a catalog of choices”. Guy came punctually with Nzo tools or appliances Or knowledge of what I asked for as an “URGENT repair/replace”. See ABC review same call. Not quite as bad as them doing same since we also still have broken HVAC too, both said they would fix ( I bought gasket already, they could have put in) or replace if they brought new toilet. Problem is not in water pipes except they need testing for lead - both said they would do this too - when I asked oak re taking a sample, how long sitting in pipes? He wiped off his soda water bottle and asked “which pipes?” !!"

"Leo was very helpful and quick to respond. We’re happy with how our 2 bathrooms turned out. Project was completed within the time promised. Our only complaint is that the workers did not clean up very well. But overall, we’re satisfied and we’ll use them again."

"Jose kept in contact with me throughout the entire process making sure that what he was doing was aligned with what I wanted. He was very professional and made sure that I was completely satisfied. I would hire them again if the need arises.."

"Went great. Good company to work with, awesome communication. They jump right on it and knock the work out quickly and cleanly. Very knowledgeable and professional."
