With homes fronted by the waters in Alameda all the way to the hillside streets in Orinda and walnut creek, the East bay homes are exposed to a combination of climatic conditions, such as cold marine air, winter and dry summers. The states of the crawl spaces render them particularly susceptible to humidity, drafts and heat loss. In the long run, that does not only erode your foundation, but also increases your energy bills.
Our crew offers full crawl space repair and encapsulation to the homes in the East Bay to ensure they stay comfortable, energy-saving and structurally sound. Sealing, insulating, and vapor barriers are some of the services that we specialize in to avoid the entry of moisture, enhance temperature control and lowering heating and cooling expenses throughout the year.

Our reputation consists of providing stable, efficient and sustainable crawl space solutions throughout the East Bay. This is the reason why homeowners trust our team:
By hiring us, you are not only buying a contractor, but a team that is interested in the comfort and performance of your home.
Most of the homeowners are unaware of the amount of energy they lose through their crawl space. The following are the most typical problems that we identify during the inspections across the East Bay:
Leaks in the air enable the conditioned air to escape and adding more use of HVAC and energy expenses.
Floored or poorly installed insulation permits the exchange of heat between floors and air on crawl space.
Spores of air that gets in through the ground cool the floors and increase humidity in the house.
We get to find the solutions to these issues at their initial stages, and this way we enable the homeowners to reclaim their indoor comfort and minimize unnecessary energy expenses.

A well-insulated crawl space is able to produce a more stable interior climate. Without insulation or insulated areas, cold air finds its way through the floor and heating becomes ineffective as well as the room temperatures become unevenly distributed across your house.
Our insulations are moisture-resistant and of high quality, which are designed specifically to insulate crawl spaces. Our insulation techniques are in concert with encapsulation systems to ensure that your floors are warm, limit drafts and prevent your foundation to be damaged due to condensation.
Floors tend to be drafty, which is usually caused by the fact that your crawl space is not sealed correctly. There are holes, fractures, and open vents that can support free movement of outside air under your house making your HVAC to strain more.
In sealing, we use professional grade materials and insulation barriers to seal each opening in our sealing procedure. No matter whether you live in Oakland, Fremont, or Walnut Creek you can find our team which will make sure that your crawl space is airtight, efficient in energy use and comfortable throughout the whole year.
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!

A quick inspection by the crew revealed minor cracks that could’ve turned into big problems. They fixed them affordably and even gave tips to prevent future issues. So glad we called them before things got worse proactive and professional!
I was hesitant about foundation repair costs, but they gave a fair quote and stuck to itno surprise fees. Their crew worked fast, cleaned up perfectly, and even explained how to maintain our foundation. Honest and skilled highly recommend!
