Why Antioch homes need these repairs

Antioch is an east Contra Costa city on the Delta with older homes near Rivertown and large 1980s–2000s subdivisions. It holds century-old river water rights, treats river water at two plants and opened a brackish water desalination plant in 2025, and hot summers and slab foundations drive the calls.
