The soils of Hercules, whether it is the homes on the waterfront of San Pablo Bay, or the hillside homes of Refugio Valley, are based on seasonal moisture, slope movement, and natural settling. Most foundations laid long ago were not constructed to accommodate current soil swellings and drainage systems resulting in cracks along a wall, walls, floor that sags, or cracks along the windows and doors. These symptoms are increasing in severity, so one can start to think of them as temporary solutions as opposed to long-term solutions, and the total replacement of the foundations is the way towards structural safety.
Our staff also offers foundation replacement services that are developed to match the geological conditions and types of architecture of Hercules. Regardless of whether your house is a Bay-view or a place in a hillside subdivision, we apply engineered systems, state-of-the-art equipment, and hardy materials to reinstate a foundation which will be able to withstand decades of movement of soil and environmental pressure.

Homeowners should be made to know the degree of commitment that they can get before trusting a team with their foundation.
Our personal approach provides homeowners with the sense of support, informed consideration, and certainty during the whole project.
Homeowners ought to know the duration of different foundation systems before deciding on which one to choose in terms of building back.
The slab foundation when designed well can serve 70-100 years when the supporting soil is stable and the foundation is well drained.
Pier and beam structures are generally expected to last between 50 and 75 years in case of proper construction materials and ventilation and shielding of the crawl area against moisture.
The current engineered foundations, which are constructed with steel reinforcement, moisture barriers, and soil specific design, are providing the longest lifespan and most of them are extending past 100 years.
With this knowledge of such lifespans, homeowners can choose the correct foundation to ensure structure durability.

One of the most crucial stages of a foundation replacement project is stabilization of the structure. Advanced hydraulic lifting systems and temporary aids are employed by our team to lift the home safely and evenly and do not impose any extra stress on framing or interior finishes. Cautious observation is taken to make the home lie level during the process.
After the house has been provided with proper support, the weak foundation is cut away in small parts and new designed ones are used in its place. This is a managed method of protecting plumbing, electrical cables as well as structural fixings that ensures that a home is stable at the point of origin until the end.
The landscape decision is significant to the long term stability of a foundation. Plants planted too near the building may create soil displacement when roots expand and also large shrubs may help in retention of moisture around the building walls. Inequality in the assessment or ornamentation, which contains water, may result in expansion of the soil, soil erosion, and structural pressure in the long run.
Homeowners can significantly increase the life of the foundation by ensuring that they have adequate grading, select the right locations to place the plants and that the water drains are not directed near the home. In the course of a foundation replacement, we assess the surrounding landscape in order to find out ways to enhance it in such a way that they save the new building in the long-term.
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.
