Golden Bay Foundation Builders has been excellent throughout my entire foundation repair and retrofit process. Our home required a few horizontal cracks patched, and a section of the foundation replaced. We also did a complete retrofit in the process. Darren the project manager has been very communicative throughout and just an overall joy to work with. Special mention to Kyndell who assisted with the inspection process to make sure everything passed. I would definitely recommend this company to any one looking for foundation work!
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.

A soft story retrofit is a structural reinforcement process applied to buildings, typically multi-story apartments or condos, that have a weak first floor. This weak level, often used for parking or retail with large openings, is prone to collapse during an earthquake. The retrofit involves adding steel frames, plywood shear walls, or moment frames to strengthen the ground floor, preventing the building from tilting or pancaking. In Walnut Creek and Contra Costa County, many older buildings require this upgrade to meet modern seismic codes. For more details on local requirements, you can refer to our internal article titled 'Top Seismic Retrofit Solutions in San Francisco | Golden Bay Foundation Builders', available at Top Seismic Retrofit Solutions in San Francisco | Golden Bay Foundation Builders. Golden Bay Foundation Builders specializes in these essential safety improvements.
The cost of a soft story earthquake retrofit varies significantly based on your specific property in Walnut Creek or Contra Costa County. Factors include the building's size, number of units, soil conditions, and the extent of structural deficiencies. A typical single-family home retrofit might range from $5,000 to $15,000, while multi-unit apartment buildings can cost $30,000 to $100,000 or more. These figures cover engineering, permits, and foundation bolting or cripple wall bracing.

Yes, a seismic retrofit is absolutely worth it for homes in earthquake-prone regions like Walnut Creek and Contra Costa County. The investment significantly reduces the risk of structural damage during a seismic event, protecting your property and family. For many older homes, particularly those built before modern building codes, a retrofit can prevent costly foundation shifts or collapses.

The most common structural failure associated with soft story collapse is a sudden buckling or shearing of the first floor's load-bearing columns or walls. This occurs when a building has a lower level with large openings for parking or retail, making it significantly weaker and more flexible than the floors above. During seismic shaking, the upper floors remain rigid while the soft story sways uncontrollably, leading to a pancake-style collapse. To protect your property in Walnut Creek and Contra Costa County, it is critical to have a professional evaluation. For further guidance on post-earthquake safety, please review our internal article titled What To Check In House After An Earthquake?. Golden Bay Foundation Builders specializes in retrofitting vulnerable structures to prevent this type of failure.
