The neighborhoods of San Leandro, starting with the eastern parts (Broadmoor and Washington Manor) and up to the Estudillo Estates, are characterized by a combination of old houses, houses on hills, and old foundations that had been moved by soil over the years. The soil in the region is of clay, which is stretched when it is raining and contracted when it is dry, creating pressure on the aged concrete structures that were not designed to experience such a degree of movement. With time, this movement brings about cracks, sagging floors, moisture intrusion and structural separation. When these problems start to develop, the most secure and sure long term strategy is usually the replacement of foundations.
Our team operates in the whole of San Leandro, where olden houses, rainy seasons, and the different soils demand robust, contemporary foundation structures. Your home can be safe, stable and long-lasting by a decade or more through a reconstruction based on new engineering and materials designed to meet the local soil behavior.

Homeowners need to know the circumstances where complete repair is required or not before deciding on which one to undertake between repair and replacement.
Such indicator signs depict massive failure in which repairs fail to work any more and replacement is the safest option.
Homeowners should learn to appreciate how contemporary practices limit the effects of foundation replacement on the environment before initiating a foundation replacement project.
The current replacement practices have focused on recycling and reuse of materials. Concrete wastes can be recycled and re-used to minimize the effect of landfills.
Modern equipment and installation processes use less energy as compared to the old ones. Our crew operates with effective equipment and reduced emission procedures in order to reduce the pressure on the environment.
The upgrades of the drainage systems, moisture and soil stabilization are made possible with the help of a new foundation and minimize the runoff and safeguard the landscape in the coming decades.
These green practices assist homeowners in making foundation replacement that does not hamper the structural health but one that does not affect the environment as much.

San Leandro is also full of older houses, some of which were constructed as far as the early 1900s, and which were built using construction materials and methods no longer applicable to the modern structural requirements. Such historic buildings are not properly reinforced, and their foundations age more quickly since they do not have enough moisture protection, soil movement, and age. The replacement of such foundations provides these homes with a safe and modern foundation and retains the initial look and architectural nature.
Our crew is cautious of historic buildings. We consider the available resources and reinforce weak places and develop foundation solutions that reinforce the home without interfering with its distinguishing characteristics. Through proper planning, foundation replacement safeguards the structure and the history that it contains.
A combination of years of practical experience working with the different home styles, soil conditions and aging foundations in San Leandro has provided our team with the knowledge of the area. We also know the effect of local weather patterns, moisture and soil movement on structural performance over the long term. It is based on this knowledge that we are able to design foundation solutions that are designed to support the conditions that your property is going to be exposed to.
Our priorities are on communication, accuracy and good workmanship in both sense of the first assessment to the last inspection. Homeowners would opt to hire our service especially due to the fact that we provide reliable, engineered foundation replacement that is supported by professionalism, expertise and stability over the long-run.
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!

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!
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!
