Mold Behind the Wall in a Winter-Vacated Building

The water damage from the burst supply line is a covered direct physical loss unless the policy contains a specific plumbing exclusion that applies. The mold exclusion bars mold itself, but the ensuing-loss exception may restore coverage for mold that ensues from a covered peril. The key factual question is causation and scope: mold that grew because water from the covered pipe break was not dried is arguably ensuing loss, while mold from long-term seepage or repeated leakage may be excluded. Even without the exception, remediation required to gain access to covered building damage or to prevent mold from interfering with covered repairs is often treated as part of the covered repair, but the insured must separate those costs from discretionary mold abatement. The public adjuster should obtain an industrial hygienist's protocol, a causation report, and a line-item estimate separating water damage, mold remediation, and tear-out. The insurer's blanket denial is weak if it did not analyze the exception. The insured should not sue before preserving the appraisal and documentation rights.

Probably not on these facts. Property forms commonly suspend coverage for building damage when the building has been vacant beyond a stated period, and some forms define vacant as not occupied or not used for its customary purpose. A rented apartment building that is temporarily empty for winter break is unoccupied, not vacant in the ordinary property-insurance sense, especially where tenants are under lease and the building remains furnished and used for rental operations. The public adjuster should prove the rental status with leases, rent rolls, utility records, and the superintendent's schedule. Business income coverage requires a suspension of operations caused by covered physical damage and a period of restoration. The insured must show lost rents or extra expenses during the reasonable time to repair, with due diligence. The insurer may still dispute the period of restoration or the amount, so the adjuster should build a month-by-month rental loss schedule and document efforts to rehouse tenants.

The adjuster should first secure the claim file and the policy, then send a written demand that identifies the covered pipe break, the mold causation evidence, the rental records, and the disputed amounts. The demand should ask the insurer to reconsider the mold denial under the ensuing-loss exception and to explain in writing why it believes the building was vacant. The adjuster should retain a hygienist and a contractor to separate covered repair costs from excluded mold abatement, and should photograph and sample affected areas before further demolition. If the policy has an appraisal clause, the adjuster should evaluate appraisal for the amount of loss while preserving coverage arguments. Suit should be a last step because of cost, the policy's suit-limitation period, and the risk of waiving appraisal. The adjuster should also advise the insured to consult coverage counsel, since the adjuster cannot give legal advice or determine bad faith.
