How residue manifests over time
Month 1-3
- Initial remediation completed
- Surface odor may be managed
- Painted walls sealed
- HVAC cleaned
Month 3-6
- Odor returning in high humidity
- Off-gassing from insulation
- Contents still off-gassing
- HVAC re-contamination possible
Month 6-12
- Paint discoloration on sealed surfaces
- Persistent odor in certain rooms
- Material degradation (carpets, fabrics)
- Health complaints (respiratory, headaches)
Month 12-18
- Supplemental claim window still open (18 months)
- Long-term material failures
- Additional scope emerges
What to do about long-tail residue
- Document as it emerges: photos, odor notes, IH testing
- IH re-assessment if significant
- File supplemental claim within 18 months
- Scope the additional work: replacement rather than recleaning
- Cite the original loss: these effects trace back to the fire
Common long-term scope items
- Drywall replacement where sealing failed
- Carpet replacement where odor returned
- Additional HVAC remediation
- Insulation replacement
- Contents final replacement (after cleaning attempts failed)
