East delta heat with winter tule fog drifting off the San Joaquin. 1990s–2000s stucco tracts; window-flashing vintages and HVAC condensate lines account for a large share of casework.
Where the work starts in Antioch
- Fog-side and north-facing elevations for chronic condensation loading

Why does local building knowledge matter in Antioch?
East delta heat with winter tule fog drifting off the San Joaquin. 1990s–2000s stucco tracts; window-flashing vintages and HVAC condensate lines account for a large share of casework. Providers who work these exact failure modes find sources faster and scope work more accurately than generalists applying a national template.
