They came out for a foundation repair, before the repair they came for an inspection that was free. This is infact an excellent company to work with. The work was done on time and our foundation is now solid and I would highly recommend.
We had an unpermitted sunroom that was improperly supported. Darren was very professional, knowledgeable, and responsive. Ignacio did the work for the project, and he is extremely good at what he does and a very hard worker. I am very happy that at least one of our walls is properly supported by a concrete foundation and our sunroom is properly supported from below.
We got multiple estimates for foundation repair, and this company stood out because they actually took time to educate us on the problem. No pressure, no scare tactics, just straightforward advice and quality work. The repairs were completed faster than expected.
I was nervous buying an older home because of potential foundation issues. Their inspection was incredibly thorough; they used a laser level to document everything and provided a detailed, honest report with no pressure to upsell. It confirmed the house was solid and made me a confident homeowner.
I contacted them for a second opinion after another contractor gave me an extremely expensive estimate. They performed a full foundation inspection and recommended a much more reasonable solution. I’m very happy with both the service and the results.

We hired them for foundation repair after noticing cracks running across our interior walls. The crew arrived on time every day and kept the work area organized. The cracks have stopped spreading and the floors feel level again.
Had these guys over at my mom's for a crawl space repair. Cordination was top notch and they mad sure to excute and complete the job as agreed.
They repaired cracks in my foundation quickly and ensured everything was stable and secure before leaving. The staff was friendly, punctual, and very detail-oriented. I would definitely use their services again.
The wide range of geography found in Richmond, both the waterfront neighborhoods close to the Marina Bay and the hillside neighborhoods that overlook the Wildcat Canyon, makes foundation conditions to be dramatically different on a street-to-street basis. Houses on Macdonald Street, Roosevelt Street, and Barrett Street tend to impermeable soil, which is subject to compressions over a long period and variation of moisture. In the meantime, real estate at the point of Richmond, the valley of El Sobrante and Carriage Hills face the problem of heavy clay soils and movement of hillsides, which may push or pull the slab foundations over the year.
Even the slightest indicators such as cracks in floor that start to grow slowly, doors that shift off center, or depression created in the center of a room can be the signs of soil instability under the slab. Since Richmond has a combination of older houses, restored buildings and new construction, every house will require a repair plan that takes into consideration the soil type, the elevation and the age. Our team is offering slab repair service that would stabilize and support the homes in all areas of the city.
There are some slabs problems, which come as a result of the initial construction of the home. The foundation support in some of the older areas of Richmond might not have been built to meet current soil conditions. In more modern developments, inappropriate compaction or shallow footing may lead to settlement not being even.
We examine the means of construction of the slab, where the design defects lead to movement, and implement repair measures that resume the right support. Through alleviating these causal problems, we cushion the house against subsequent displacing or structural strains.
The shrinkage of the soil occurs during the warmer seasons of Richmond and mainly in soils that are clay based. This part describes the shrinking of soil, which causes voids below the slab resulting in cracks, sinking and internal misalignment. We repair it by ensuring that the soil is strong, the weak areas are strengthened, and the level is restored.
We reinforce areas under the slab whereby there is pulling off of the soil because it has been dry.
Our techniques restore what is structurally damaged and do not allow it to go further.
Our use of moisture patterns and strengthening of deeper layers of soil stabilizes the home.
Homeowners have confidence in us since we are not interested in sealing the symptoms of the damage to the slab but the actual cause. Before deciding on the appropriate way to repair it, we utilize highly sophisticated diagnostic devices to assess the behavior and drainage patterns, as well as the structural performance of soil.
Symptoms of slab repair may include:
We determine the supporting parts of the slab that are losing their support and support them to make them long term stable.
The foundation support of the homes in Richmond is frequently weakened by the long-term soil erosion, multiple moisture cycles, or by construction aging. We buttress them, keep the sinking areas in place, and make the slab stronger to resist the soil movements in the future. Cracks, sloping floors and structural strain will not reoccur since we will have restored even load distribution.
We’re here to help! Swiftly addressing these concerns is key. Our experts will promptly inspect and repair your foundation, ensuring the lasting strength and safety of your home. Reach out without hesitation for reliable assistance.

For minor cracks or settling, you might spend a few hundred dollars on epoxy injections or simple patching. However, major structural repairs, such as installing steel piers or helical piles to stabilize a sinking foundation, can range from $5,000 to $15,000 or more. In areas like Walnut Creek and Contra Costa County, soil conditions often play a significant role in pricing.

Yes, slab foundations can be repaired. The specific method depends on the type and severity of the damage. Common issues like minor cracks or settling are often addressed with slab jacking (also known as mudjacking or polyurethane injection), which lifts the concrete back into position. For more significant structural problems caused by soil movement or poor compaction, piering (using steel or concrete piers) is a standard solution to transfer the load to stable soil. At Golden Bay Foundation Builders, we always recommend a thorough inspection first to determine the root cause. For damage related to freeze-thaw cycles, our internal article titled Can Frost Action Damage Be Repaired? provides specific guidance on repair techniques. Professional evaluation ensures the repair is durable and addresses underlying issues.
The best time for foundation repair in Walnut Creek and Contra Costa County is typically during the dry summer and early fall months. This period offers stable soil conditions, which are crucial for a successful repair. Dry ground allows for proper excavation, concrete curing, and ensures that the foundation materials set correctly without the interference of rain or excessive moisture. Attempting repairs during the rainy winter season can lead to complications, such as soil shifting or prolonged curing times. For a detailed breakdown of seasonal considerations, you can refer to our internal article What Is The Best Time Of Year For Foundation Repair?. At Golden Bay Foundation Builders, we always recommend scheduling a professional evaluation to determine the optimal timing for your specific project.
In most standard homeowner insurance policies, foundation repair is not covered unless the damage is caused by a specific, named peril, such as a sudden plumbing burst, fire, or a vehicle collision. Typical exclusions include damage from earth movement (earthquake, landslide, settlement), soil expansion, or gradual water seepage, which are common causes of foundation issues in Walnut Creek and Contra Costa County. For a clear understanding of your coverage and legal rights regarding foundation repairs, we recommend reviewing our internal article titled Foundation Repair Warranties And California Homeowner Legal Rights. At Golden Bay Foundation Builders, we always advise homeowners to carefully read their policy declarations and consult their agent before assuming coverage, as many policies specifically exclude "settling" or "cracking" of the foundation.
