Top-Rated Fence Contractor in San Lorenzo CA - Protecting Your Property

San Lorenzo was built primarily between 1945 and 1960 by developer David Bohannon, who put up thousands of small tract homes in a short stretch of time. That means most of the housing stock is now 65 to 80 years old - and a lot of the original concrete, fencing, and flatwork that came with those homes is showing its age. Homeowners throughout the Village are dealing with fences that have been gradually pushed out of plumb by decades of soil movement, cracked posts, and boards that have rotted at the base from years of contact with damp clay soil.

The clay-heavy soil under San Lorenzo is one of the most consistent challenges for fence work in this area. It expands when it absorbs winter rain and shrinks back during the dry summer months, and that cycle slowly moves anything set into the ground. Properties near San Lorenzo Creek face an added challenge: the creek corridor raises the local water table during wet years, which keeps soil moisture elevated and accelerates wood decay. A contractor who has not worked in San Lorenzo before may not account for these conditions when setting posts - leading to fences that start leaning well before they should.

San Lorenzo is an unincorporated community in Alameda County, located between San Leandro to the north and Hayward to the south, along the western edge of the East Bay. The neighborhood was largely developed by builder David Bohannon starting in 1944 as one of the Bay Area's first large-scale planned postwar suburbs. The original development, known as San Lorenzo Village, set the character that most of the community still carries today: modest single-family homes on similar-sized lots, laid out in a regular grid pattern with clear residential streets. According to the community's history, San Lorenzo was one of the first communities in the country to be developed at this scale under one builder.

The community has roughly 26,000 to 28,000 residents packed into about 3.5 square miles, making it one of the denser unincorporated areas in Alameda County. San Lorenzo Creek runs through the western part of the neighborhood before emptying into San Francisco Bay, and properties near the creek corridor carry a higher flood-zone designation that affects drainage planning and sometimes exterior work timelines. The community is well connected by Interstate 880 and has consistent commuter access to Oakland, Hayward, and San Jose. Neighboring San Leandro to the north shares much of the same Bohannon-era housing stock and similar soil and climate conditions.
