Absolutely. Encapsulation is financially and structurally rewarding to a majority of the homeowners in Castro Valley. It averts incurring damages that might end up costing thousands of dollars in repairs in future- particular in areas near Lake Chabot and Palomares Hills which are more likely to have moisture.
Also, most homeowners gain significantly reduced energy bill and enhanced comfort in their homes. Encapsulation is among the cleverest investments you can make on your home when it comes to constant maintenance, and possible damage to the foundation.
Poor drainage or saturation of the soil leads to pooling of the soil under the houses. The space is dry by installing a sump pump and perimeter drain.
Due to high humidity, there is the possibility of mold growth, which is dangerous to air quality. A dehumidifier and a vapor barrier is used to prevent growth and to get rid of odor.
The hills surrounding the houses in Castro Valley may cause movements of the soil that may lead to instability of the foundation. Sealing and structural repair strengthens the long term stability.
so that the system can work over decades – and under your roof you can have a dry and clean and insecure world.
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.
