Napa has a larger share of pre-1960 housing than most California cities of its size, and much of that stock is concentrated in the neighborhoods near downtown - the streets around Jefferson, Seminary, Oak, and Randolph where Victorian and craftsman homes from the 1880s through 1930s are still in active use. These homes were built with soft brick and lime-based mortars that cannot accept modern Portland cement repairs without cracking. A contractor who applies the wrong mortar mix to a century-old chimney will cause the brick face to spall within a few seasons, a problem that is far more expensive than the original repair. The 2014 South Napa earthquake compounded these challenges: the magnitude 6.0 event is the strongest to hit the Bay Area since 1989, and it left hidden damage in chimneys, foundations, and masonry walls across the city that is still being uncovered and repaired today.

Napa’s climate creates a second pressure on masonry work that is separate from the seismic risk. Summers regularly push into the 90s with little humidity and intense UV exposure that bakes mortar and cracks sealants. Then November arrives with heavy rain - Napa averages 25 to 30 inches annually, most falling in a concentrated wet season - and that water drives straight into any gap the summer left behind. Tree roots from the large oaks and walnuts common on older Napa lots add a third factor: root pressure under driveways, walkways, and foundation walls causes heaving that looks like soil movement but has a mechanical source. All three of these factors need to be understood before any repair approach is chosen.

Napa is a city of roughly 80,000 people at the southern gateway to the Napa Valley, one of the most recognized wine-producing regions in the world. The city sits along the Napa River, and its downtown is anchored by the walkable stretch of First and Main Streets, with restaurants, boutiques, and the popular Oxbow Public Market on the riverfront. The Historic District preserves Victorian-era commercial buildings alongside more recent development, and the Napa Valley Wine Train depot near downtown is a landmark nearly every Napa resident knows. The surrounding hills and vineyards give the city a character that is distinct from the rest of the Bay Area, and the older residential streets near downtown feel more like a small Northern California town than a suburb.

About half of Napa’s housing units are owner-occupied, and the residential stock spans more than a century of building styles - from the ornate Victorians and craftsman bungalows on streets like Seminary and Jefferson to the postwar ranch homes on larger lots further from the core, and the stucco subdivisions built in the 1980s and 1990s on the eastern edges of the city. Napa is also close to American Canyon to the south, a newer city with its own distinct housing stock that we also serve, and to the wine country communities further up the valley where stone and masonry work is as much about the landscape as the structure.
