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!
Residency in Moraga implies the serene beauty of such neighborhoods as Rheem, Campolinda, and the hilly terrain around landmarks like the Mulholland Ridge Open Space Preserve, Saint Mary’s College, and Moraga Commons Park.

Pressure-treated lumber, steel-reinforced beams, or engineered options (resistant to rot and moisture) are some of the lumber products that we recommend in the Moraga climate. To ensure our team checks the existing crawl space condition to identify the material that will give the longest life and provide most support to your home.
