When you are in Pleasant Hill with all its quiet, tree-lined neighborhoods (Poets Corner and Sherman Acres) and landmarks (Pleasant Hill Park and the Contra Costa Centre Transit Village, etc.) around, you realize how proud people are of their houses.
The same feeling of pride and protection is evident in our team. That is why we are specialized in seismic and earthquake retrofitting – so that whatever is under Pleasant Hill begins to go, your home or building would remain safe.
Pleasant Hill is located in the center of the East Bay which is an area of the active seismic activity, such as the faults of Hayward and Calaveras. Even a moderate earthquake may lead to the cracks on the foundation, walls separation or structural movement. In our opinion, each household and enterprise should be secure, stable and prepared to face the unforeseen.
In the process of retrofit, we fortify the base and other key points of your building and minimize the chances of significant damages in the case of a seismic event. It is either the 1950s ranch-style house in the area of Gregory Gardens or the modern mixed-use building in the locality of Crescent Plaza, and all we want is to ensure that your structure is not falling down.
Our crew starts by conducting a thorough on-site inspection of your foundation, frame work and existing hardware. We seek weaknesses that are specific to your type of structure and location
We then create a retrofit plan which follows the layout of your home, be it around Boyd Road, Paso Nogal Park or the downtown area. Our field records, engineering software and local building code are combined to make sure that there is precision.
The retrofit is performed by our appropriately trained crew with the help of code-compliant materials and methods. All the bolts, braces and plates are fitted in accordance with both city and state seismic standards.
After doing so, we issue certification papers and before and after photographs, which gives you the comfort and assurance of the requirement.
We integrate engineering knowledge with local knowledge to design each retrofit to the building type and soil conditions of Pleasant Hill. This is what our service entails in totality:
Our team will inspect and sign off each detail to the seismic standards of California because of initial inspection up to final inspection.
Being a locally based group, we are conversant with the diversity of architecture in Pleasant Hill: mid-century ranch houses in College Park as well as contemporary infill developments along Oak Park Boulevard. We have designed buildings with the California Modernism, post-war suburban design and transitional craftsman plans.
We also have the added advantage of having local experience in our permitting processes of the city, soil differences in Pleasant Hill, and the surrounding areas of Concord or Walnut Creek, and the reaction of the local infrastructure in the event of a seismic activity in the region. That is the difference of collaboration with retrofit team which understands your area, your architecture and your requirements.

After noticing doors sticking and cracks in our drywall here in Warm Springs, we called for a foundation inspection. The team was incredibly thorough, using laser levels to measure settling and explaining everything in plain terms.
Nisan was very helpful on guiding me via the permit process for earthquake retrofit. Work was executed quickly. Thanks
We were very happy with the results of our inspection with Ryan! He explained the settling in homes and what things we should look for, and was very professional, friendly, and efficient. 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.

The cost of seismic retrofitting a home varies significantly based on the property's size, location, construction type, and the specific work required. For a typical single-family home in a high-risk area, basic foundation bolting and cripple wall bracing can range from $3,000 to $7,000. More comprehensive retrofits, including soft-story corrections or hillside foundation upgrades, can cost $10,000 to $30,000 or more. It is crucial to obtain multiple detailed quotes from licensed, experienced contractors who specialize in this work. The investment is substantial but critical for safety and structural integrity, especially in seismically active regions. For a deeper understanding of the necessity behind this work, we recommend reading our internal article, Why Bay Area Homes Need Earthquake Retrofitting.
A seismic retrofit is a significant investment, but it is often worth it for the substantial protection and peace of mind it provides. The primary value lies in safeguarding lives and preventing catastrophic property damage during an earthquake. For older buildings, retrofitting brings them up to modern safety codes, which can also reduce insurance premiums and increase property value. It is a proactive measure that can prevent far greater financial loss from repair costs and business interruption after a seismic event. For a detailed analysis of the process and benefits, we recommend reading our internal article, Seismic Retrofitting and Earthquake Retrofitting. The decision ultimately depends on your building's location, age, and construction type, but for most properties in seismic zones, the long-term benefits strongly justify the cost.
Yes, there are several grants and financial assistance programs available for earthquake retrofitting in California. The most prominent state-run initiative is the Earthquake Brace + Bolt (EBB) program, which provides grants to help homeowners cover the cost of seismic upgrades for older houses built before 1980. This program specifically funds the bracing of cripple walls and bolting houses to their foundations. For detailed information on eligibility and the application process, you should review our internal article on the Earthquake Brace and Bolt Program. Beyond EBB, some local city and county programs offer additional rebates or low-interest loans. It is crucial to consult with a licensed structural engineer or qualified contractor to determine the necessary retrofitting work for your specific property before applying for any financial assistance.
The duration of a seismic retrofit project varies significantly based on the building's size, construction type, and the extent of work required. For a typical single-family home, a basic retrofit focusing on cripple wall bracing and foundation bolting might take a professional crew one to three weeks. Larger commercial buildings or complex retrofits involving shear walls, moment frames, or soft-story modifications can take several months to over a year. Key factors include engineering design time, permit acquisition, and potential unforeseen structural issues discovered during construction. Proper planning with a qualified structural engineer is crucial for an accurate timeline.
