To live in Martinez is to be enchanted with Alhambra valley, waterfront neighborhoods adjacent to Martinez Marina, the vintage homes around vine hill and the historical nature of downtown around the John Muir House. No matter whether your house is located near the Hidden Lakes Park, the undulating hills of the Reliez Valley or the tree-lined streets around the Rankin Park, our crew is aware of how the clay-rich soil, the terrain of the hills, and seasonal rain-and-dry conditions may affect the foundations of your piers and beams.
Floors may sink, doors may stick, or cracks may be found in all parts of the interior over time by the settlement of the soil, too much moisture in the crawl-space, or rotting wood. Moisture-control strategies, detailed inspections, and precision repairs all contribute to making Martinez homeowners safe, which is why we assist them in preserving their foundations and ensuring long-term stability. Our crew installs local expertise and field experience to bring a sense of safety and strength under your house.

Before discussing the impact of drainage to the pier and beam foundations, it is important to know about drainage. Many of the problems that cause long-term instability are prevented by the proper management of water.
You are insulating the piers and beams, and the entire support system under your Martinez house by making sure that your property is well drained.
The crawl space should be improved in a strategic manner. Three major ways through which our team stabilizes and reinforces failing pier and beam systems will be given below.
When joists or beams start to lose strength, sag or rot, we provide strength back to them by either sistering new timber, replacing damaged parts that are in severe condition or making extra supports to spread the load in the right direction.
The cause of the crawl-space deterioration is often moisture. Vapor barriers, drainage and ventilation upgrades are done to ensure that beams remain dry and are not compromised by long-term weakening.

The movement of a pier and beam foundation is frequently indicated by sticking doors and windows. With soil swelling, shrinking, or moving under the house, the framing may twist or sink unevenly, as an opening that was previously aligned may become distorted.
In Martinez, the clay soil causes significant contribution to the these problems- particularly during wet winters and dry summers. We examine the origin of the issue by checking beam straitness, pier, and crawl-space hydrate. After source identification, we apply leveling, structural reinforcement or moisture management to restore normal and consistent functioning of your home doors and windows.
We trust in openness, completeness and sustainability. The inspection of your crawl space by our team determines every important factor, such as the quality of the beam, the alignment of the piers, the behavior of the soil, the issues of moisture, and the quality of ventilation. We describe our findings in a manner that you are able to know the repairs that must be completed and the reasons.
We do not provide fast solutions but rather do high quality workmanship that will last several decades to secure your home. Our results-oriented approach to structural reinforcement to leveling and moisture control means that your foundation gets the job it rightfully deserves.
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.
