Between the mountain ranges of Diablo and the shaded streets of the Iron Horse Trail, Danville houses are constructed to be comfortable and attractive, but still, there is something under the floorboard that usually remains unknown. The steep topography of the area and seasonal precipitation puts crawl spaces at a particularly high risk of floods and moulding, as well as foundation stress. With time the simplest of water issues can result in significant structural issues.
Our company focuses on crawl space repairs and encapsulation to Danville residents. We are aware of the local soil conditions, drainage and weather conditions that affect the stability of foundations. We ensure your home is dry, healthy, and sound; in sealing, waterproofing, and fixing drains, we do it all the way down to the ground.

Long term protection needs to be waterproofed. To prevent the intrusion of moisture, our team employs both drainage enhancements and drainage vapor covers and seals. Each house is different and therefore, we evaluate their soil type, grading, and foundation material and then advise accordingly.
In the case of Danville homes that surround the Sycamore Valley Park or Camino Tassajara, these customized waterproofing systems will avoid both surface and subsurface water damages -this guarantees a full-time protection of the crawl space.
We then determine the cause of the damage before we start repairing. The following are the concerns that we are the most frequent when it comes to Danville properties:
Humidity is sustained through poor ventilation that provides the best conditions of the growth of molds and rotting of wood.
Poor drain or low areas mean that water is going to fill the area under your floors contributing to the weakened structural support.
Soil in the area of Danville contains a lot of clay, which swells and contracts resulting in uneven floors and cracks.
Early removal of these issues will save you the hassle of incurring expensive repairs in the future – and making your crawl space dry and stable all year round.
This comprehensive examination is to make sure that your foundation is covered closely and that you sort out all the problems before they get complicated.

By emphasizing the long-term results and integrity in the work, we have gained the trust of people in Danville who have a home. This is what works in favor of our team:
We do not see any project as our work but as our home since the foundation is your peace of mind.
The effects of flooding can easily cause the deterioration of the foundation and poor indoor air quality under your home. The most prevalent reasons are the improper yard grading, a large amount of rain, and blocked up perimeter drains.
We are installing and maintaining an efficient drainage, vapour barriers and sump pumps to redirect the water off your foundation. Together with regular maintenance, they prevent flooding before it occurs and maintain structural integrity of your home.
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.
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!

I was hesitant about foundation repair costs, but they gave a fair quote and stuck to itno surprise fees. Their crew worked fast, cleaned up perfectly, and even explained how to maintain our foundation. Honest and skilled highly recommend!
