How category 3 water damage works in Casa de Oro

That local housing mix shapes where we look first for this scenario.
Why category 3 water damage shows up in Casa de Oro
Category 3 work around El Cajon, Santee, and Lakeside includes sewage and outdoor water tied to slab leaks year-round and roof or runoff events in wet weeks. In slab-on-grade tracts and canyon-adjacent homes, porous disposal volume rises quickly, and dry air that helps drying once the source is stopped stretches the dry-out after sanitizing.
