Orinda, located in the rolling hills between Lafayette and Berkeley, has a reputation of beautiful hillside houses, tree-shaded streets, and quiet suburban living. The fertile land and favorable climate which render it desirable, also bring with them the undesirable elements, rodents, insects and other pests that breed well in damp unsealed crawl spaces.
We are specializing in closing up the holes, enhancing drainage, and designing barriers that stop pests and enable your foundation to remain dry and your home air to maintain its purity. You can live near Orinda Country Club, Sleepy Hollow or downtown and our service we will help you protect your home against moisture and pests all throughout each year.

We take pride in the fact that we are the reliable crawl space professionals to the homeowners of the Lamorinda and the surrounding Orinda. This is what our team boasts about:
Our vision is to provide the peace of mind that is long-lasting, clean, dry, and free of pests.
The slightest of openings can act as an invitation to pests. The following are the most common points of entry by them into crawl spaces in Orinda houses:
Openings in foundation wall or vents which are tiny provide easy access to rodents and insects.
The electrical penetrations and plumbing are usually ignored on building and serve the ideal routes of entry.
Vent screens become loose or corroded with time to allow free entry of pests and moisture.
Through our encapsulation process, we close all these weaknesses and have a tightly sealed crawl space that is well encased.

Rodents are opportunistic, they can squeeze between the opening as small as a quarter-inch and get inside your crawl space. When they are there, they chew insulation, drop droppings and cause serious health and odor problems.
We start our rodent-proofing process by performing a complete inspection in order to find and close all of the entry points. We tie down the heavy-duty wire mesh, replace the broken insulation, and strengthen weak spots to make sure that the pests will remain outside forever. We seal, clean up and preventively maintain your crawl space to keep it healthy and rodent-free.
Not only does encapsulation help in keeping moisture out but also it is one of the best methods of preventing pests into your crawl space. When we seal off the vents, use vapor barriers and regulate the humidity, we have created a place where the rodents cannot survive and neither can the insect.
The systems that we have created of encapsulation are reinforced barriers, and accurate sealing techniques that will destroy food sources and habitats. What comes out is a clean, dry and pest resistant foundation that will protect your whole house.
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!

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!
