Mold Behind the Shower Wall: Ensuing Loss, Sublimit, and Code Upgrade
A homeowners policy on a $400,000 dwelling has replacement cost coverage, a $2,500 deductible, a $10,000 mold sublimit, and ordinance-or-law coverage equal to 10% of the dwelling limit. Water damage from plumbing is covered; flood is excluded. A supply line behind a shower fails, water soaks the wall cavity, and mold is found across 80 square feet. The town inspector requires the contractor to remove the wall to the studs and install mold-resistant drywall and a new exhaust fan to meet current code. The contractor's estimate is $62,000: $35,000 for tear-out and rebuild of the bathroom, $18,000 for mold remediation, and $9,000 for code-required drywall and fan. The carrier paid $14,000 for emergency drying and tear-out and denied the rest, citing the mold exclusion and the ordinance-or-law exclusion. The insured wants the public adjuster to demand the full $62,000, arguing the mold is an ensuing loss and the bathroom will not match without a full rebuild.
1. Analyze coverage for the mold remediation and the code upgrades. What is payable to the insured under the policy?
Read the worked answer
Start with causation. A failed supply line is a covered plumbing water loss; the mold is not a separate cause but an ensuing result of water that was already covered. The mold exclusion should not erase the whole claim, but the $10,000 mold sublimit caps mold remediation, testing, and similar costs. The ordinance-or-law coverage is a separate grant, up to 10% of $400,000 = $40,000, but it applies only to code-required work, not general upgrades. The $9,000 drywall and fan item must be tied to a written inspector citation showing current code requires it. The $35,000 tear-out and rebuild must be separated into direct water damage, access needed for remediation, and elective remodeling. Matching may require reasonable matching of undamaged materials, but it does not automatically convert a bathroom repair into a full $62,000 rebuild.
2. Compute a reasonable maximum payment and explain how the deductible and sublimit apply. Is the carrier's denial of everything beyond $14,000 defensible?
Read the worked answer
A defensible maximum, assuming the $35,000 is direct covered water damage and access and the $9,000 is truly code-required, is $35,000 + $10,000 mold sublimit + $9,000 code = $54,000, less the $2,500 deductible = $51,500. If the policy's mold sublimit includes mold-related tear-out, or if the $35,000 includes mold remediation, the payment is lower. The carrier's $14,000 emergency payment should be credited so it does not pay twice. The denial of the entire remainder is too broad: the mold sublimit is not an exclusion, and the ordinance coverage may apply. The PA should submit a line-item reconciliation and demand a written coverage position, not simply the full $62,000.
3. What documentation and claim-handling steps should the public adjuster take?
Read the worked answer
Get a written mold protocol and causation letter from an industrial hygienist; photograph moisture readings and the failed line; obtain the inspector's code citation; separate the estimate into covered water damage, mold remediation, code upgrades, and noncovered improvements. Send a proof-of-loss supplement with the breakdown and a coverage argument. Request the policy's mold and ordinance endorsements. Preserve samples and records. If the carrier maintains the denial, invoke appraisal if the dispute is only the amount of loss; if it is coverage, request a written denial and evaluate regulatory or bad-faith options. Do not let the contractor begin elective upgrades before coverage is confirmed.
