Why your neighbors trust Bay Area Underpinning

We've earned 19 five star reviews.

"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!"

Common Causes of your Foundation Problems in Sunnyvale

Water Damage

Excess water from leaks, heavy rains, or floods can weaken the foundation by accumulating around it, leading to cracks and structural issues.

Expansive Soil

Certain types of soil, particularly those rich in clay minerals, are prone to expansion when wet and contraction when dry, exerting pressure on your foundation.

Poor Drainage

Improper drainage systems can lead to water pooling around the foundation, increasing the risk of water damage and soil erosion.

Tree Roots

Roots from nearby trees can grow under the foundation, causing it to shift or crack as they expand.

Plumbing Leaks

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

Climate Conditions

Extreme weather conditions, such as droughts or heavy rains, can cause soil to expand or contract, putting stress on the foundation.

These common causes highlight the importance of regular maintenance and inspections to prevent foundation damage and ensure the longevity of your home.
