Jacksonville averages 77 percent relative humidity year-round. Coastal proximity and the St. Johns River create microclimates where indoor humidity spikes during summer months. Even without water intrusion, homes in Riverside, Ortega, and San Marco experience condensation inside wall cavities. Insurance adjusters use this against you. They argue the mold resulted from ambient humidity, not a covered event. We counter this with hygrometer data showing your indoor humidity was normal before the water intrusion. We also reference ASHRAE standards proving that mold does not colonize in 24 hours from humidity alone. It requires standing water or saturation, which only happens during a covered event like a pipe failure.
Jacksonville sits in FEMA flood zones that require separate flood insurance. Many homeowners in Arlington and Northside assume their standard policy covers hurricane-related mold. It does not. If storm surge or rain intrusion caused the mold, your HO-3 policy excludes it. Only a flood policy through NFIP or a private carrier covers that scenario. We verify your coverage before you file and prevent the confusion that leads to denied claims. Local expertise matters because adjusters from out of state do not always understand Jacksonville's flood dynamics. We do. We have worked claims after every major storm since Irma. We know how to separate wind damage, which is covered, from flood damage, which requires separate coverage.
