Wind, Surge, and Mold After a Named Storm
Hurricane Elena makes landfall near Biloxi. A homeowner policy provides dwelling coverage of $450,000, a 2% hurricane deductible, a $10,000 mold sublimit, a water damage exclusion with an ensuing-loss exception, and replacement cost coverage. Separate NFIP flood coverage provides $250,000 building coverage. After the storm, the adjuster finds roof shingles lifted by wind over the kitchen; rain entered for two days; drywall is saturated; mold is visible in 400 square feet; and the first floor flooded with 18 inches of surge. The insured's contractor says the mold resulted from wind-driven rain, but the flood adjuster says the surge wet the same drywall. The insured submitted a $180,000 estimate that includes $40,000 of mold remediation. The adjuster has not inspected the attic or obtained a meteorological report. The insured demands payment within 10 days and threatens appraisal.
1. How should the adjuster separate wind and flood damage, and what investigation is needed before payment?
Read the worked answer
The policy covers wind damage and excludes flood; the NFIP policy covers the surge. The adjuster should not rely on the contractor's or flood adjuster's conclusion alone. Inspect the attic, roof decking, and wall cavities; map moisture and mold; photograph shingle uplift and water lines; obtain a meteorological report on wind speed, rainfall, and surge timing; and get an engineer's causation report. Separate the loss by cause: wind-created roof openings and rain intrusion are potentially covered; surge that entered the first floor is flood. If the policy has anti-concurrent-causation language, excluded flood that contributed to the same damage may defeat coverage for that part. The adjuster should allocate mold remediation by cause and document each item. Pay only undisputed covered wind damage promptly and explain the flood referral. Do not use the flood adjuster's scope as the property adjuster's scope.
2. How do the 2% hurricane deductible and $10,000 mold sublimit apply to the estimate?
Read the worked answer
The hurricane deductible is 2% of the dwelling limit: 0.02 x $450,000 = $9,000. It applies to the hurricane-caused loss under the homeowners policy, not to the separate flood policy, which has its own deductible. The mold sublimit is $10,000, so even if $40,000 of mold remediation is otherwise covered, the homeowners policy pays no more than $10,000 for mold, subject to the cause analysis. The deductible applies before or after the sublimit according to the policy's order; typically the sublimit caps the covered loss and the deductible applies to the total covered loss. The adjuster should show a build-up: covered wind damage, covered mold capped at $10,000, then the $9,000 hurricane deductible. If the mold is caused by excluded flood, it is not covered at all under the property policy. The insured may have limited NFIP coverage for flood-related mold; explain that separately.
3. The insured demands payment in 10 days and threatens appraisal. What is the proper response?
Read the worked answer
Acknowledge the demand in writing, explain that the cause-of-loss investigation is active, and identify the information needed. Pay any undisputed covered wind damage within the applicable time frame rather than withholding everything. Do not use the 10-day demand as a reason to pay an unverified $180,000 estimate. Appraisal resolves the amount of loss when coverage is accepted; it does not decide causation or coverage. If the dispute is only about the amount of covered wind damage, the insurer can invoke appraisal or agree to it. If coverage is disputed because of flood, appraisal is not the right forum for that issue. Document the investigation, the meteorology, the engineer's report, and all communications. Avoid threats and keep the insured informed. Refer the flood portion to the NFIP adjuster and coordinate so the insured does not receive duplicate payment.
