"I will sleep much better tonight. I noticed a crack in my foundation and called Bay Area Underpinning. Hunter came out and walked the entire property and went underneath my house. He identified one other issue that I knew about besides the crack and told me they could fix that too. I had no idea you can call structural engineers for chimneys. His quote was fair to me and you can't beat the warranty and financing. Today Jesus Villagomes and Erick Baez came out and fixed the crack, they also looked around underneath and reassured me AGAIN that my house was in good shape. Because I caught it early they were able to fill the crack and then add a carbon fiber exposy seal. They also sealed the crack from the outside, even though they had already filled it in under the house. They were professional, answered all my questions, no matter how many and honestly were just pleasant to work with. They also explained my maintenance plan so I knew what to expect. I would absolutely recommend this entire team, to stay professionally kind in high heat is amazing. The Chimney job is pending and again, I'm ahead of the curve and not waiting for it to get worse."

Common Causes of your Foundation Problems in San Rafael

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.
