A BIG thanks to Ryan and his crew for doing an excellent job doing the Earthquake Brace & Boldt at my parent's house. Easy to work with from the beginning to the end and completed in a timely manner. Also, Ryan answered all my questions even on his days off (Thanks again Ryan!).
These guys came highly recommended and didn’t disappoint, professional, fast, and very communicative throughout the process. Now I feel a lot safer knowing the structure is reinforced.
David was a lifesaver when it came to fixing our foundation issues. He thoroughly explained the problem areas and worked efficiently. We felt confident in the repairs and appreciated his attention to detail.
Nisan was very helpful on guiding me via the permit process for earthquake retrofit. Work was executed quickly. Thanks
Had a great experience working with Kyndell from Golden Bay Foundation Builders. I recently purchased the home and was looking for help with earthquake retrofitting options. He inspected my foundation carefully and determined that past bolting was likely adequate. He had suggestions about monitoring the foundation. He was very thoughtful and detailed in his approach, and worked to determine what was best for the home. In this case, that meant no need for additional work now. But if I need any additional assistance in the future, will be calling him again.
We needed crawl space repairs due to pests and moisture damage. They sealed it up, reinforced the beams, and added vapor barriersnow it’s dry and structurally sound. Excellent service from start to finish!
Our home needed retrofitting, and they did an amazing job reinforcing the foundation. They preserved the home’s character while making it structurally sound. If you need an expert who respects older homes, these are your guys.
We had a terrible experience with another contractor before finding these guys. They corrected the shoddy work, fixed our foundation properly, and treated us with respect. Finally, a business that stands by their word and does quality work.
We had a sinking foundation that caused doors to stick, but they fixed it with piers and proper leveling. Their team was professional, answered all our questions, and even followed up afterward. No more sticking doorsjust a solid, stable home.
A quick inspection by the crew revealed minor cracks that could’ve turned into big problems. They fixed them affordably and even gave tips to prevent future issues. So glad we called them before things got worse proactive and professional!
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.

Foundation repair costs vary widely based on the severity of the issue, the size of your home, and the type of repair needed. 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. For a detailed breakdown of expenses and what to expect for your specific situation, we recommend reviewing our internal article titled FAQ: Foundation Repairs – Golden Bay Foundation Builders. Golden Bay Foundation Builders always provides a thorough inspection before offering a precise estimate.
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.
