Residency in Moraga implies the serene beauty of such neighborhoods as Rheem, Campolinda, and the hilly terrain in the area of the Mulholland Ridge Open Space Preserve. The combination of older home in the hills and traditional California ranch-style houses makes the area particularly attractive, however, the pier and beam foundation is highly exposed to soil movement, moisture and natural ageing. We are aware of such local conditions and shape our approach to repair based on the terrain and architectural styles of Moraga.
Homeowners in Moraga trust our team to provide accurate services of pier and beam foundation repair whenever they have to deal with an issue of sagging floors, damp crawl spaces, or unstable support beams. We carry with us the years of experience in dealing with the clay-based Lafayette Valley soils and the higher home designs prevalent in the areas surrounding Saint Mary’s College, thus making sure that each repair is structurally sound, and long lasting and tailored to the localities.

We do an extensive crawl-space inspection before making any repair recommendation. This will make sure that we find out not only the obvious problems but the concealed problems that may pose a danger to the structure of your house.
Our meticulous inspection process makes it so that, with all these inspections, our crew makes sure that each Moraga home gets exactly the correct repairs it requires and not an extra bit of it.
We also work with homeowners on a regular basis and in many instances there were temporary DIY solutions that were implemented only to find out that the issues were not just getting worse. Whereas short term fixes can provide a momentary reprieve, the Moraga soil movement and the levels of humidity need trained personnel who have the equipment and the structural knowledge to provide long term stability.
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.
The houses surrounding woodland are particularly vulnerable to termite attacks such as Rancho Laguna Park. We assist homeowners to check on soft wood, hollow sounding beam, visible tunnels and sagging floor areas- symptoms of possible broken and compromised foundation system which requires your immediate consideration.
Learning about them puts the owners of Moraga in a clear position of making the right decisions regarding the security of their houses and the safety of their structure over a long span of time.

By the title We Fix Sagging Floors, Weak Piers and Structural Damage our team provides detailed repair solutions bringing the floors and piers back to the correct height and level. Our high leveling and bracing systems are specially made of pier and beam structures which are present in this area.
A lot of Moraga houses are also built on sloping lots exerting pressure on some points of the foundations.

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.
