"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!"

"Enriquez and his crew actually went above and beyond the original scope of work. Although he decided to replace more of the sidewalk concrete than quoted, he held the original price. Quality of the finishing was excellent as was the communication. Many positive comments from neighbors. I'd hire them in a wink if I needed more work."

"I cannot say enough about how good this experience with John Mountain/Mountain Engineering has been. They said it would be 3 weeks; anti was. The work was painstakingly done, including a French drain behind the wall. And they replaced the plants that were destroyed during the process, which was an unexpected bonus."

"Bob is great to work with. He communicates clearly, sets expectations for timing and costs and regularly exceeds those expectations. He is a joy to work with. I picked deck installation which he did, but he also replaced doors and windows, repaired cinderblocks, got us a new roof, and did landscaping work and other jobs at our house in Dillon Beach. I highly recommend Bob and Precedent Construction."

Foundation Repair questions, answered by experts

Underpinning is a specific type of foundation repair where a specialist installs deep piers under a foundation to provide additional support. This method is often used when the soil beneath the foundation can no longer evenly support the structure. Foundation repair is an umbrella term that includes many methods. Besides underpinning, other common repairs include foundation crack repair, waterproofing, cosmetic repairs, and concrete block wall stabilization. Often, underpinning is accompanied by other work to address the root cause of the foundation issue, such as regrading the yard to ensure water drains away from the house.

Most single-story homes don't have foundations strong enough to support a second story, but they can be reinforced for an addition. A structural engineer can assess your foundation and what needs to be done to get it ready. They'll look at any cracks or unevenness in your current foundation and consider any special framing or beams your home needs, especially if it’s in a high-wind or hurricane area.

“To support a second story, many structural engineers will require that you install additional concrete piers in the crawlspace,” says Tschudi. “This involves hand excavating, pouring a large concrete footing—usually with specially coated rebar—and then building concrete piers right up to the girders.”

You can buy a home with foundation issues, but understanding the extent of the problem and what solution you need is critical. If you learn that a home you’re trying to buy has a foundation problem, it’s not necessarily a deal breaker, but you should have a professional assess the issue to see how severe it is and know when to walk away from a foundation problem. Foundation issues can necessitate simple and affordable solutions or complex work that costs thousands. 

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.
