Burst Supply Line, Mold, and the Seepage Exclusion
On January 9, a tenant in a Des Moines duplex called the property manager about water dripping from a ceiling light. A plumber found a pinhole failure in a copper supply line above the kitchen ceiling. Water had soaked drywall, cabinets, and insulation. The public adjuster's remediation contractor found mold in the ceiling cavity and behind the cabinets, totaling $28,000 of the $72,000 claim. The tenant said she had noticed a "musty smell" about three weeks earlier but saw no water. The HO-3 policy covers "sudden and accidental discharge or overflow of water or steam from a plumbing system," excludes "constant or repeated seepage or leakage of water over a period of 14 days or more," and limits mold to $10,000. The insurer denied the entire claim, citing the seepage exclusion and mold exclusion. The public adjuster has the failed section of pipe, the plumber's invoice, moisture readings, and photographs.
1. Analyze coverage for the water damage and the mold under the policy language.
Read the worked answer
The claim must be split. The grant of coverage applies to a sudden and accidental discharge from a plumbing system. A pinhole failure in a copper supply line is the classic sudden discharge. The water damage to drywall, cabinets, insulation, and flooring is therefore potentially covered.
The seepage exclusion requires constant or repeated leakage over 14 days or more. A musty smell three weeks earlier is evidence to investigate, but it does not by itself prove a 14-day leak. The insurer must show the leak persisted for the stated period. The plumber's report, pipe failure mode, moisture readings, and absence of prior visible water support a sudden event.
The mold is different. The policy limits mold to $10,000, so the $28,000 mold remediation cannot be recovered in full even if it resulted from covered water damage. The insurer still must pay covered water damage and the covered portion of mold up to the limit. It cannot deny the entire claim simply because mold is present.
2. What evidence should the public adjuster develop to defeat the seepage exclusion?
Read the worked answer
The adjuster should build a timeline. Obtain the tenant's written statement describing when she first noticed the smell, whether there was any prior staining, and when she first saw water. Get the property manager's maintenance records and any prior plumbing invoices. The plumber should document the pinhole's condition and explain whether it was a sudden failure or long-term corrosion with active leakage.
Photographs and moisture mapping should show the affected area and the absence of long-term staining, rot, or repeated repairs. The adjuster should preserve the failed pipe section and ask the plumber to state whether the pipe was wet only at the failure point. If the tenant's musty smell predated the visible leak, the adjuster should have the remediation contractor opine on whether mold can develop within the observed timeframe and whether the smell could have another source.
The adjuster should also demand the insurer's claim file notes and any expert report supporting the 14-day conclusion. If the insurer relied only on the smell, that is a weak factual basis for a broad exclusion.
3. What should the public adjuster demand and advise the insured to do next?
Read the worked answer
Demand an itemized written denial that separates covered water damage from mold and identifies the specific policy language and facts supporting the 14-day seepage conclusion. Submit a supplement that allocates the claim: water damage to structure and cabinets, mold remediation up to the $10,000 limit, and any tear-out costs needed to access the mold. Ask the insurer to confirm whether tear-out is treated as part of the mold limit or as covered water damage.
Advise the insured to mitigate further damage, keep damaged materials available for inspection, and not to discard the failed pipe. Do not let the insured sign a release. If the insurer accepts coverage but disputes the amount, appraisal may help; if it denies coverage, appraisal cannot decide the exclusion. The insured should be advised of the right to consult Iowa counsel and to file a complaint with the Iowa Insurance Division if the insurer refuses to evaluate the claim reasonably. The adjuster should not give legal advice or promise a specific recovery.
