"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!"

"The Cortez Brothers did an exceptional job. They viewed the property right away. Provided an estimate within adequate time. Went over my preferences. Rebuilt a fence and addition. Were very polite. Kept me in the loop with emails and phone calls. Their work turned out absolutely beautiful. I highly recommend them. I will be hiring them for painting various patio areas. With the many contractors I've worked with in the past I've felt very lucky to have found them."

He was patient, walking me through each step of the process, especially when I changed my mind and had new ideas. When I had a problem with my gate due to weather conditions, Alex made the repair with no hesitation. His team was thorough and courteous as well. I am so pleased with the quality and beauty of my retaining wall. Thank you for a job well done, Alex."

Foundation Repair FAQs, answered by experts

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.

Whether your homeowners insurance covers slab leak repairs depends on your specific policy and the cause of the leak. Many policies cover slab leaks resulting from a covered peril, such as a natural disaster, a falling tree, or pipes freezing and bursting within the slab. However, damage caused by invading tree roots, corrosion, or leaks from appliances may not be covered by a standard policy. It's a good idea to also check your home warranty plan for potential coverage if an appliance is the source. Contact your insurance provider for a full explanation of what your policy covers.

If your concrete steps have crumbled or chipped, you can fix them by removing any chips or flakes, cleaning and wetting the affected area, applying a concrete bonding agent, and finally applying new concrete, usually in the form of Portland cement. For widespread damage, you can consider concrete resurfacing instead. For fixing concrete spalling that has led to deep damage, you might need to remove damaged material, add structural supports, and pour new concrete into a mold.

No, hairline cracks in concrete are generally not a problem as they do not impact the strength and longevity of the concrete. Generally, cracks less than 0.3 millimeter wide don’t impact the structure. Hairline cracks can grow over time and weaken the structure, such as in a home foundation. Some hairline cracks can also cause leaks in a foundation. It’s important to watch the cracks to see if they grow. Contact a concrete contractor if you notice cracks exceeding 0.3 millimeter wide.

You can use epoxy-based concrete fillers to repair small cracks and dents in the floor. For larger damages, remove any debris, then patch the cracks or holes with concrete repair products or resurface the entire floor. We recommend using fast-curing products that cure in four hours. You can also buy a pre-mixed concrete patch and leveler if you are only repairing parts of your floor.
