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.
Whether one speaks of rolling hills of Orinda and Lafayette or the coastal fringes of Richmond and Martinez, the terrain of the Contra Costa County is as diversified as beautiful — and that diversity causes its own drainage problems, from the busy areas near Broadway Plaza to the residential zones around Heather Farm Park. Intensive downpours on steep slopes occur during heavy rains whereas the flat valley districts have a way of trapping the water which leaks out in lawns, basements as well as crawl spaces.
We combine engineering accuracy and harmony with the landscape that keeps your property functional and attractive. Running off hillside, flooding the yard or the basement, we shape each system to the terrain and type of soil of your property- developing a clear cut solution that blends with the surrounding natural environment.
Professional drainage installation is not only a question of resolving the existing problems, but also of avoiding the new ones. A well-constructed system will secure the foundation of your home, save you on maintaining a house, and add to the overall value of the property.
High-quality materials, accurate mapping of the elevation and tested methods are used in our installations to make them reliable in the long-term. Your system will be in place and will silently guard your home through all the storm seasons decades later.
The terrain of Contra Costa County is a combination of coastal, hilly, and valley lands that require drainage systems that can fit the terrain. These are specific regional issues to which our custom solutions provide an answer that is narrowly focused and attentive.
Our drainage systems are designed in layers, which regulate water runoffs, stabilize the soil as well as safeguard the retaining walls.
In case of lower-lying areas, we will use surface drains in combination with underground piping to remove standing water and avoid stress on the foundations.
Our design forward practices ensure that your outdoor areas are functional, appealing and free of floods.
Even an ideal drainage system can use seasonal inspection even in an area with changing soil and seasonal rainfall such as the Contra Costa County. Your system is maintained by our programs that ensure that it is clean, efficient, and storm ready.

The four main types of drainage systems used in residential construction are surface drainage, subsurface drainage, slope drainage, and downspout drainage. Surface drainage removes excess water from the ground surface using shallow ditches or swales. Subsurface drainage, often involving French drains or perforated pipes, captures groundwater before it saturates the soil around your foundation. Slope drainage relies on grading the land away from the structure to direct water flow. Downspout drainage channels rainwater from gutters away from the base of the home. Properly integrating these systems is critical for preventing soil erosion and hydrostatic pressure. For a deeper understanding of how these methods protect your home, we recommend reviewing our internal article titled The Role Of Drainage Systems In Protecting Your Foundation Class.
Yes, many professional landscapers are equipped to address drainage problems, but the scope of their work varies. For surface-level issues like grading, French drains, or dry wells, a skilled landscaper can be an excellent choice. However, if the drainage issue is directly impacting your home's foundation, such as causing soil erosion or hydrostatic pressure, you should consult a specialized contractor. Golden Bay Foundation Builders recommends that any drainage work near your foundation be carefully coordinated with foundation repair experts to ensure long-term stability.

For homeowners in Walnut Creek and Contra Costa County, the most affordable drainage solution is typically a simple surface-level swale or a properly graded yard. A swale, which is a shallow, gently sloping ditch, redirects rainwater away from the foundation using gravity without expensive pumps or piping. This method requires minimal materials and can often be done with basic landscaping tools. However, the cheapest option is not always the most effective for severe water issues. Golden Bay Foundation Builders recommends assessing your specific soil type and water flow before committing to any method. While a swale is budget-friendly, a more permanent solution like a French drain may be necessary for persistent problems to avoid costly foundation damage later.
The cost of a backyard drainage system varies widely based on the scope of work, property size, and soil conditions in Walnut Creek and Contra Costa County. A simple French drain installation typically ranges from $2,500 to $6,000, while more complex systems involving multiple catch basins or dry wells can cost between $8,000 and $15,000. Factors like clay-heavy soil, which is common in our area, often require deeper trenching and additional grading, increasing labor expenses. For a thorough understanding of how these systems protect your home, we recommend reviewing our internal article titled The Role Of Drainage Systems In Protecting Your Foundation Class.
