El Cerrito is a neighborhood area between the Berkeley Hills and San Francisco bay which has homes on the hillsides, ocean breezes and wide variety of architecture- mid-century ranch houses and more recent hillside constructions. These conditions, though, which make the city so beautiful, exert their pressure on your crawl space too. Water in the air, moving slopy soil, and the changes in temperatures may cause the foundation to be unstable, result in humidity, and even cause low quality of indoor air.
Our area of concern is to manage the moisture, strengthen structural supports, as well as to enhance the energy performance of your home. You may live close to Arlington Park, Moeser Lane, or Potrero Avenue, but we will bring you the best foundation protection and ensure your home is more convenient and comfortable.

The air leaks and drafts that exist under your home cause your HVAC system to work the hardest. Crawl space encapsulation involves a closed environment through sealing of the vents, laying vapor barriers, and avoiding air flow between the crawl space and the living spaces.
Our group has assisted many homeowners in El Cerrito to enhance the performance of HVAC systems and minimize system pressure. Having fewer temperature changes and reduced humidity intrusion, your heating and cooling system will be more efficient and save you money, as well as increase their life span.
The ventilated spaces may have a direct impact on the air that you inhale in your house. This is what we usually see when we investigate the premises around El Cerrito:
Hot air in your HVAC system combines with cold ground water, resulting in condensation and build up of moisture.
Persistent odors that are released by mold spores and damp wood are carried by way of vents and flooring.
Allergens, bacteria and moisture are distributed across your house by air flowing through floor boards.
Allergens, bacteria and moisture are distributed across your house by air flowing through floor boards.

Our reputation is based on accuracy, quality and on what the customer wants. This is why people who live in El Cerrito have faith in our team:
It is not very complex, our mission is to insure your home at the bottom, make it comfortable at the top and to offer solutions that will withstand the time.
Conservation of energy begins at the grassroots. By covering and insulating the crawl space, your home keeps warm during the winter and will be cooler during the summer. That would make the heating and cooling systems cycle less often, which would translate into observable savings in energy.
Our El Cerrito clients usually record a 1525 percent of their monthly energy bill reduction following repair and encapsulation. These additions will easily recoup themselves and add value to your house in a short amount of time and with reduced utility bills as well.
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!
