Get matched with top foundation drainage installers and replacers in Walnut Creek, 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!"

"Victor is good on this work. We had him doing entire landscape plan for new construction. I am happy with his work. One thing stands out him from the other is his knowledge about hard scape and flexible to change things. Bravo Victor"

"Responsive, friendly, punctual, and highly competent. It helped that I was overseeing the work because some decisions and improvisation had to be done on the fly with the repair of a sprinkler valve, installation of and two ball-valve cutoffs, and relocation of an adjacent faucet."

"The team was amazing! We had an old deck in our backyard and we hired Palm Construction to replace and extend it and they did a great work! The job was done in less than 2 weeks, Communication was great, they cared about the backyard and plants and we are so happy itâ s all ready just before summer. Highly recommended!!"

"Greg and Brian were friendly, very knowledgeable and very hard-working. They completed my retaining wall job and even added significantly more steel than my engineer called for at no additional cost. There were no unwanted surprises. I would use them again. Good guys."

"My backyard project included installing a new redwood side fence, replacing old redwood fence boards on the back fence, removing the lawn and brick walkway and installing a new concrete patio in those areas, installing a new wood safety guard rail and installing a new ADA compliant handrail to use when walking down the backyard steps to the laundry room. I am so happy and pleased with the results! Babylon Builders transformed my backyard into a beautiful, safe space that I will enjoy for many years to come. It was a pleasure working closely with Ron on my project. Juan and his crew performed excellent, outstanding work and they always cleaned up very well. I feel so blessed and fortunate that I found Babylon Builders. I highly recommend them! Many thanks for a job well done, Babylon Builders!"

"Mike showed up asap, scoped the job requirements, gave a written estimate that was accepted by insurance company, had team out next morning to roll up rug in bedroom, break through concrete floor, locate actual leak (~6" laterally from where professional had estimated it to be) and about 18" beneath floor surface, repaired pipe, pressurized system to check it, however repaired pipe leaked (crimping a fitting onto corroded pipe didn't work), then properly cleaned, sweated new piece of pipe into place, repressurized system, inspected new work to verify success, filled hole with sand, covered and leveled that with freshly mixed concrete. All was completed in 1 day. Kudos. Thanks, Mike! Your timely response was greatly appreciated! Mike's bid was higher than that of the leak detection company; however, Mike's company was far more responsive to our need for hot water and was there the next day. The lower bid came from a company that wanted us to wait 21 days(!) for them to repair it. Since we had an understanding insurance company, they were willing to pay the higher cost for our comfort and convenience. That's right! You read it correctly. An insurance company that looked beyond their bottom line to put our needs first."

They helped me to be able To visualize my kitchen before we even installed it 3D design and samples. I already felt i had it installed. We selected all the materials and doors. Very detail."
