Foundation Repair

San Anselmo’s picturesque setting, surrounded by hills and creeks, presents specific foundation challenges for homeowners. The area’s hilly terrain and expansive clay soils can cause foundation settling, leading to cracks in walls, uneven floors, and other structural issues. Properties built on slopes are particularly vulnerable to soil erosion and hillside movement, which can put additional stress on foundations.

Flooding is also a concern in San Anselmo, particularly in low-lying areas near creeks that are prone to overflowing during heavy rains. This can lead to significant water intrusion and foundation damage if proper drainage systems are not in place. Homeowners often require French drains, sump pumps, and improved grading to manage water flow and protect foundations from hydrostatic pressure.

Seismic risks in San Anselmo stem from its proximity to the San Andreas Fault and other active fault lines in the region. Older homes that lack modern seismic reinforcements are especially vulnerable during earthquakes. Seismic retrofitting—such as foundation bolting, cripple wall bracing, and the installation of shear walls—can help safeguard homes and improve their resilience against seismic events.
