Common fragmentation patterns
Water + Mold split
- Water damage scope capped separately
- Mold remediation under sublimit
- Rebuild scope contested between the two
Fire + Water split
- Firefighting water characterized separately
- Separate deductibles applied
- Scope boundary artificial
Wind + Flood split
- Hurricane damage partitioned between HO-3 and flood policy
- Interior water contested as wind-driven vs. flood
- Double submission + double deductibles
Structural + Cosmetic split
- Structural work in one scope
- Cosmetic/finish in separate supplemental
- Extended timelines
Why it favors carriers
- Sublimits apply to individual components
- Multiple deductibles
- Each component re-scrutinized
- Extended timelines and complexity
How to counter
- Characterize as single loss from covered peril
- Invoke ensuing-loss and resulting-damage doctrines
- Cite specific policy language supporting unified treatment
- Avoid lumping everything into the capped category (e.g., mold sublimit)
Documentation strategy
- Single loss narrative
- Clear causation chain
- Scope attribution that supports unified coverage where favorable
