Antioch grew rapidly in two waves - the 1980s and again in the late 1990s through the mid-2000s - producing large subdivisions of single-family homes across the eastern and hillside parts of the city. That means a significant portion of Antioch's driveways and parking surfaces are now 20 or more years old, which is precisely when original pavement begins showing the accumulated damage from years of seasonal soil movement. Antioch's clay-heavy soils expand every wet winter and contract every dry summer, and that repeated cycle stresses pavement from below whether it shows on the surface yet or not.

The climate adds a second pressure. Antioch is far enough inland that summer temperatures regularly hit the high 90s and sometimes cross 100 degrees Fahrenheit. That sustained heat oxidizes asphalt binder faster than in coastal cities, turning surfaces from flexible to brittle within a few seasons if they are not protected with regular sealcoating. A contractor who works primarily on the coast and then takes jobs in Antioch may not appreciate how quickly the combination of heat and clay soils can destroy an under-built surface - and you will not see the shortcuts until two or three summers later, when the cracking starts.

Antioch is the largest city in eastern Contra Costa County, with a population well over 100,000. It sits on the south bank of the San Joaquin River at the edge of the Sacramento-San Joaquin Delta, which gives the city its identity as a gateway to Delta boating and recreation. The housing stock spans two distinct eras: older neighborhoods near the historic Rivertown waterfront district with wood-frame homes from the early 1900s through the 1960s, and large newer subdivisions covering the eastern hills built during the 1990s and 2000s growth wave. Those two eras have different maintenance profiles, and contractors who work here regularly know the difference.

The eBART station near the eastern edge of the city, which opened in 2018, has made Antioch a more prominent transit node in the East Bay. Major commercial corridors run along Lone Tree Way and Somersville Road, where shopping centers and big-box retailers serve the broader eastern county population. We serve all of Antioch, including the east-side neighborhoods near Prewett Family Park, and we also cover neighboring Brentwood to the south - a city with its own mix of newer residential development and farmland-adjacent properties that present different paving conditions.
