Danville has two distinct housing eras that create two very different sets of paving needs. The older ranch-style homes near the historic downtown core, built mostly in the 1960s and 1970s, have driveways that have been in service for 50 to 60 years - long enough that the original asphalt has oxidized, cracked, and often been patched multiple times. The clay soils underlying most of the San Ramon Valley have been moving under those driveways every winter and summer for decades. At this point, many of those surfaces need honest evaluation rather than another round of patching - and a contractor who can tell you when a surface has reached end-of-life is more valuable than one who will sealcoat anything just to close a sale.

The newer executive homes on the hillside edges of Danville, built from the 1980s through the 2000s, come with a different challenge: larger driveways, more hardscape, and more complex lot grading that puts more demands on both the drainage system and the pavement structure. Sloped driveways on clay-heavy soil are particularly vulnerable to base erosion because winter runoff concentrates on the surface and moves quickly toward the low end of the property. Any pavement on a sloped Danville lot that was not installed with proper drainage provisions will fail faster than the same surface on a flat lot - the slope amplifies every weakness in the base and drainage design.

Danville is a town of around 43,000 people in the San Ramon Valley, roughly 30 miles east of San Francisco in Contra Costa County. Incorporated in 1982 but with roots going back to the mid-1800s, it has a historic downtown core centered on Hartz Avenue with shops, restaurants, and preserved buildings that give the town a distinct character compared to its newer suburban neighbors. Interstate 680 runs north-south through town, connecting Danville to Walnut Creek to the north and San Jose to the south, with Sycamore Valley Road and Diablo Road serving as the main local cross streets. The town is home to the Eugene O'Neill National Historic Site at Tao House, managed by the National Park Service, which tells you something about how seriously this community values its history and its built environment.

The housing stock is a mix of 1960s and 1970s ranch-style homes near the older parts of town and larger executive properties in the planned neighborhoods and hillside subdivisions closer to Mount Diablo State Park. Lots throughout Danville tend to be generous by Bay Area standards, which translates to longer driveways, more hardscape, and more surface area that needs periodic maintenance. We serve Walnut Creek and Pleasant Hill throughout the valley as well, and the same crew and knowledge base that handles those communities extends to every neighborhood in Danville.
