Why your neighbors trust Groundworks

We've earned 347 five star reviews.

"I recommend Bay Area Underpinning for an important reason: honesty. After careful inspection, their agent, Richard, told me the truth, which was that my crawlspace was fine, that I had no problem with moisture or settling. And then he took the time to show me why. He could have tried to sell me on doing a lot of work, but he didn't. This kind of honesty is impressive! Call Bay Area Underpinning to inspect your crawlspace. You can trust them. If they say it needs work, hire them to do it. I am almost sorry I couldn't!"

Types of Foundation Damage in Mill Valley

Common Causes of your Foundation Problems in Mill Valley

Soil Settlement

Shifting or sinking soil under your foundation causes uneven settling, which can lead to cracks and structural issues.

Moisture Changes

Seasonal soil changes, like expansion during wet periods and shrinking during dry spells, put stress on your foundation, leading to cracks and instability.

Tree Roots

Nearby growing tree roots can shift the soil beneath your foundation, causing cracks and uneven support.

Hydrostatic Pressure

Saturated soil creates hydrostatic pressure, pushing against foundation walls and causing cracks or bowing over time.

Plumbing Leaks

Plumbing leaks near your foundation can saturate the soil, weakening its stability and leading to foundation movement or cracks.

Temperature Changes

Freeze-thaw cycles cause the soil around your home to expand and contract, which can cause for your foundation to shift and cause damage.

Climate Conditions

Heavy rains or drought can cause soil to shift, leading to cracks and instability in your foundation. Foundation repair restores stability, protecting your home from further damage and ensuring long-term safety.
