High-Quality Excavation Services in San Francisco, CA
Working in San Francisco requires a level of precision, planning, and technical expertise that few excavation companies can deliver. Lassiter Excavating is proud to serve San Francisco with specialized excavation, drilling, and site-preparation services tailored to the city’s dense neighborhoods, steep grades, and uniquely complex soil conditions. With decades of experience across the Bay Area, we help residential and commercial clients navigate the challenges of building in one of the most demanding environments in California.
Specialized Site Prep for Urban Builds
Space is limited in San Francisco, which makes proper site preparation essential. Our team performs efficient clearing and grading in tight-access areas while maintaining strict compliance with city regulations. We understand the importance of drainage, compaction, and stability on sloped or narrow lots, and we prepare your site so contractors can move forward without delays.
Precision Excavation for Remodels & New Construction
From foundations for major renovations in classic SF homes to excavation for modern infill construction, Lassiter Excavating brings accuracy and safety to every project. We are experienced in working around neighboring structures, retaining existing features, and operating equipment in confined spaces. Whether you’re digging out a basement, preparing a building pad, or opening trenches for utilities, our crews deliver clean, dependable results.
Pier Drilling for Hillside & Structural Support
San Francisco’s hills and seismic requirements make deep foundation work essential. We provide professional pier drilling for homes, additions, decks, retaining walls, and commercial projects requiring engineered support. Our operators work closely with geotechnical engineers to ensure each pier meets strict load-bearing and depth specifications.
Retaining Walls & Slope Stabilization
For properties built on inclines or with shifting soil, we install retaining walls that provide both structural stability and visual appeal. Our solutions help control erosion, protect foundations, and support hillside construction throughout the city.
Safety & Utility Awareness
Urban excavation demands careful planning. We prioritize utility locating, traffic coordination, and safe operation to protect neighboring properties and ensure a smooth project timeline. To inquire about our work, contact us here.
