Homeowners Water Loss with Mold Sub-Limit and Long-Term Seepage
On January 4, a homeowner returns to her Bedford, NH, house after a 12-day vacation and finds water pouring from a second-floor toilet supply line. A plumber determines the braided line failed from corrosion and estimates it had been seeping for several weeks before the full rupture; there is dark staining along the first-floor ceiling. The HO-3 policy has Coverage A $400,000, Coverage C $200,000, loss-of-use limit $80,000, a $2,500 all-perils deductible, and a $10,000 mold remediation sublimit. The adjuster's inspection finds: structural drying and repairs $46,000; mold remediation $18,000; damaged furniture and clothing $11,000; and three weeks of hotel and meals while repairs are made $7,200. The insured also wants $4,000 to replace undamaged hardwood flooring in two rooms to 'match' the repaired area. The policy contains the standard water exclusion for constant or repeated seepage over 14 days. The home is uninhabitable for 21 days.
1. Is the loss covered? Analyze the sudden discharge versus constant seepage issue and the mold sublimit.
Read the worked answer
The HO-3 covers accidental discharge from a plumbing system, but it excludes constant or repeated seepage or leakage over 14 days or more. The plumber's estimate that the line seeped for several weeks creates a genuine coverage issue: staining and saturation that developed gradually may fall within the exclusion, while the final rupture is a sudden discharge. The adjuster should not decide from the plumber's oral estimate alone; an engineer or leak investigator should determine when the staining began and whether the damage is consistent with a long-term leak. The insured bears the burden of proving a sudden loss; the insurer bears the burden of proving an exclusion. Mold resulting from covered water damage is payable only up to the $10,000 sublimit, and mold caused by excluded long-term seepage may not be covered at all. The adjuster should issue a reservation of rights, document the causation evidence, and allocate any covered sudden-rupture damage separately from excluded seepage damage.
2. Calculate the maximum payable under the policy, showing each coverage and limit. Assume the adjuster determines the entire loss resulted from the sudden rupture and mold is covered except for the sublimit.

Coverage A: $46,000 minus the $2,500 deductible equals $43,500. Mold remediation is $18,000, but the sublimit pays no more than $10,000, so $10,000. Coverage C furniture and clothing is $11,000. Loss of use is $7,200, which is within the $80,000 limit. The $4,000 for undamaged hardwood flooring is not payable merely for cosmetic matching because the HO-3 does not promise matching and no matching endorsement or ordinance-or-law coverage is stated. The total is $43,500 + $10,000 + $11,000 + $7,200 = $71,700. The adjuster should confirm that the mold remediation invoice does not include work already paid in the structural repairs, and should document that the deductible was applied once to the covered property loss. If the policy has a separate deductible for Coverage C, the calculation would change, but the stated facts provide one all-perils deductible.
3. What if the investigation shows the line had been dripping for 20 days before rupture? How would that change the analysis and payment?
Read the worked answer
If the line was dripping continuously for 20 days, the loss is no longer simply a sudden rupture. The constant or repeated seepage exclusion applies to water damage from leakage over 14 days or more, so the gradual saturation, staining, and mold would likely be excluded. The insured could still recover for damage caused by a distinct sudden rupture on January 4 if the evidence separates that event from the long-term seepage. The adjuster would need to allocate: pre-rupture seepage damage and mold excluded; sudden-rupture damage covered, subject to the deductible and any mold sublimit for covered mold. If the damage cannot be separated because the same water caused all of it, the exclusion may bar the entire water-damage claim, and the insured would bear the burden of proving a covered sudden event. The adjuster should obtain a detailed causation report, update the reservation of rights, and explain the allocation in writing rather than denying or paying the whole claim without analysis.
