"A huge thank you to Jason! Since we moved into our house a year and a half ago, we've been hearing a strange wood-rubbing sound quite frequently. After doing some research online, I suspected there might be an issue with the foundation, so I reached out to Bay Area Underpinning, one of the few foundation companies that offer free on-site estimates. Jason Dye arrived right on time, carefully checked for any cracks, assessed the foundation levels, and measured the moisture level in the crawl space with their tools. He then provided his professional opinions. Jason is really nice, honest, and very knowledgeable. Highly recommend!"

Types of Crawl Space Damage in Cupertino

Common Causes of your Crawl Space Problems in Cupertino

Moisture and Humidity

Excess moisture and high humidity levels in the crawl space can lead to mold growth, wood rot, and structural damage. This often results from poor ventilation or water seepage.

Poor Drainage

Inadequate drainage systems can cause water to accumulate around the foundation, leading to water infiltration and increased moisture levels in the crawl space.

Open Crawl Space Vents

Open vents allow outside air and moisture to enter the crawl space, which can lead to condensation, mold growth, and pest infestations.

Foundation Cracks

Cracks in the foundation can compromise the structural integrity of your home by allowing water infiltration, which can lead to further deterioration and instability.

Plumbing Leaks

Leaks from plumbing systems can saturate the soil around the foundation, leading to erosion and weakening of the structure.

Understanding these common causes can help you take proactive measures to protect your crawl space and maintain the overall health of your home.
