A structure fire in Daly City, CA creates three distinct damage zones: the fire zone (thermal and structural damage), the smoke migration zone (smoke and soot deposits extending beyond the fire zone), and the suppression water zone (structural saturation from firefighting water). Bundling these three zones into a single fire damage scope is the most common documentation error in fire claims — and it produces under-documented scopes that delay settlement. DryZone Recovery is IICRC FSRT certified to document all three zones separately from the first assessment. Call (833) 652-9398 now.
Smoke migration zones in structure fires regularly extend 3-5 rooms beyond the fire zone — smoke travels through HVAC systems, wall penetrations, and door gaps under the pressure differential that develops during firefighting operations. The smoke migration zone has its own restoration scope (surface cleaning, HVAC treatment, possible cavity decontamination for properties where smoke entered wall cavities through electrical penetrations) that is distinct from the fire zone scope. When smoke damage is bundled into the fire zone scope rather than mapped as its own zone, the extent of smoke deposit is frequently under-represented and the HVAC component is often omitted entirely.
The suppression water zone is similarly under-represented when it isn't mapped independently. A residential structure fire response typically deploys 500-1,500 gallons of water — enough to saturate building assemblies throughout the structure, not just the fire zone. The suppression water zone requires the same Category 3 classification, structural drying scope, and IICRC ASD documentation as any other Category 3 water event. DryZone Recovery produces the suppression water zone documentation as a separate scope item within the fire claim — the format your CA adjuster needs to process all three damage types correctly.
Thermal damage extent, structural compromise assessment, and char/burn scope — documented per IICRC FSRT standards. Fire zone boundaries are established separately from smoke and water zones on the zone map.
Soot deposit mapping using controlled wipe samples extends the smoke zone boundary to the confirmed soot deposit perimeter. HVAC inspection within the smoke migration zone identifies duct penetration of soot — a scope item that requires dedicated HVAC cleaning documentation separate from surface restoration scope.
Moisture meter mapping of the suppression water zone establishes the Category 3 structural saturation boundary. IICRC ASD structural drying protocol applies to the suppression water zone — daily moisture monitoring, equipment log, and dry standard confirmation at zone close — formatted as a supplement to the fire zone scope for your CA carrier.
