UC Union City Fences has served San Lorenzo fence jobs since 2017, installing wood privacy fences, chain link, and vinyl on the postwar homes throughout the community. We respond within one business day and provide written quotes at no charge.

San Lorenzo's clay-heavy soils expand and contract with every rainy season, working fence posts loose and pushing panels out of alignment. Our fence repair service addresses leaning posts, broken boards, and gate hardware failure before a small problem becomes a full replacement.
Most of San Lorenzo's postwar tract homes sit on modest lots where a wood privacy fence is the most natural fit for both style and budget. We install cedar and redwood fencing suited to the neighborhood's residential character and the humid East Bay air that can cause untreated wood to warp faster than expected.
Many San Lorenzo homeowners with side yards, rear lots, or properties near San Lorenzo Creek use chain link because it holds up in wet conditions and does not rot or swell with moisture. It is also a practical choice for landlords managing rental properties where low maintenance matters as much as durability.
Vinyl is a smart choice for San Lorenzo homeowners who want a clean look without committing to repainting every few years. It shrugs off the moisture that comes with East Bay winters and the marine air from the Bay without cracking or fading the way painted wood does over time.
San Lorenzo's dense residential streets mean dogs need a secure yard rather than a long leash. We install pet-safe fencing with no gaps at ground level and gate closures that hold up to daily use, so your dog stays in and neighborhood foot traffic stays out.
Homes built in San Lorenzo during the Bohannon era are now 70 to 80 years old, and many have original or near-original fences that have simply run out of useful life. We handle full tear-out and replacement, including post removal, grading, and disposal, so you start clean with a fence built to current code.
San Lorenzo sits on clay-heavy East Bay soils that behave differently from sandy or loamy ground. Every winter, rain causes the clay to expand. Every summer, it dries out and shrinks. That repeated movement exerts pressure on fence posts from every direction, and after a few decades it loosens even posts that were set correctly. Add in the fact that most homes here were built between 1945 and 1960, and you have a neighborhood full of fences that have been cycling through that stress for half a century or more.
Properties near San Lorenzo Creek face an additional layer of challenge. The creek corridor affects drainage patterns across a wide band of the neighborhood, and homes closer to the water can have softer, wetter soil for much of the year. Fence posts set in saturated soil heave and settle faster than those in drier ground. Alameda County also maintains flood control responsibilities in this area, so any fence work near the creek corridor may involve setback requirements enforced at the county level rather than a local city hall. Knowing these local details before showing up on a job makes a real difference in the final result.
Our crew works throughout San Lorenzo regularly, and we understand the local conditions that affect fence contractor work here. Because San Lorenzo is an unincorporated community, permits come from the Alameda County Planning and Building Department rather than a city office. Our team is familiar with that process and pulls permits on your behalf so no step gets missed.
San Lorenzo Village, the original Bohannon-built neighborhood at the community's core, has residential streets where lots are close together and shared fence lines between neighbors are common. We handle neighbor coordination, property line questions, and shared post agreements as part of nearly every job in this area. The streets running off Hesperian Boulevard and East 14th Street are ones our crews know well.
We also regularly handle projects in Castro Valley to the east, where hillside lots and clay soil create a similar set of fence challenges. If your home sits anywhere near the Hayward border or close to Hayward, we cover that entire stretch of the East Bay flatlands.
Reach us by phone or through the contact form and we will respond within one business day. We will ask a few questions about your property and what you need so we can come prepared.
We visit your San Lorenzo property and walk the fence line with you. The written quote covers materials, labor, permit fees, and debris removal so there are no hidden costs after the work starts.
If a permit is required through Alameda County, we file the paperwork and schedule your installation once it is approved. You do not need to visit any county office or manage any forms yourself.
Most San Lorenzo fence jobs are completed in one to two days. We haul away all old materials and leave the site clean, so your yard looks better on day one, not just when the fence ages in.

San Lorenzo is an unincorporated community in Alameda County with roughly 26,000 to 28,000 residents packed into about 3.5 square miles. It sits between San Leandro and Hayward along the west side of the county, close to Interstate 880. The community grew almost entirely during the late 1940s and early 1950s when developer David Bohannon built thousands of small tract homes in rapid succession. That history gives San Lorenzo a remarkably consistent character, where block after block of one-story homes share similar floor plans, lot sizes, and original building materials. The housing stock is now 70 to 80 years old, and the neighborhood has the maintenance needs that come with age.
San Lorenzo Creek cuts through the community before emptying into San Francisco Bay, and the creek corridor is a defining geographic feature that affects drainage across a wide band of properties. The community is mostly residential with a modest commercial strip, and homeownership rates hover around 50 percent, which means about half the homes are owner-occupied and half are rentals. Neighbors in San Leandro to the north and Hayward to the south have similar housing stocks and many of the same fence service needs.
