How category 3 water damage works in Rancho Bernardo
In Rancho Bernardo, category 3 water damage is a specialized restoration scenario, not a generic service page. Rancho Bernardo water damage scope is shaped by the community's phased master-plan build-out from the 1960s through the 1990s. That local housing mix shapes where we look first for this scenario.
Why category 3 water damage shows up in Rancho Bernardo
Category 3 work around Escondido, San Marcos, Vista, and Poway includes sewage and outdoor water tied to appliance failures and slab leaks. In 1970s-90s tract homes on slab, porous disposal volume rises quickly, and lower ambient RH that still cannot save undried cavities stretches the dry-out after sanitizing.

- Housing stock: 1970s-90s tract homes on slab
