Three Weeks Away, Two Different Events

Start with the exact wording, because two versions of the exclusion exist. Many forms exclude "constant or repeated seepage or leakage of water over a period of 14 days or more," and some add "even if the insured was not aware of the seepage." Others require the insured's knowledge. The leak detector's three-to-five-week estimate puts this squarely past 14 days.

• Drywall and paint ($8,000). Excluded if the no-knowledge wording applies. If the form requires knowledge, the Rileys have a genuine argument: they were 1,000 miles away and had no way to observe the leak. Read the clause before committing.
• Mold ($26,000). Either way, the $10,000 sublimit caps it. Mold here is not an "ensuing loss" - ensuing loss restores coverage when a separate covered peril follows an excluded one; it does not convert the direct consequence of excluded seepage into a covered loss.
• Vanity ($4,500). Direct physical damage from the same excluded cause, so it follows the drywall's fate.
• Do not forget the deductible - it never gets to that stage if the February damage is excluded.
• Reservation of rights. Issue one now, get the full leak-detection report, and confirm when the shutoff valve was last serviced.

Treat March 2 as a new and separate loss event, and cover the sudden discharge.

• The burst itself. Sudden and accidental discharge of water from a plumbing system is a named peril. It does not matter that the technician was negligent: negligence is not an exclusion, and the "faulty workmanship" exclusion (if the form has one) applies to the cost of correcting the work itself, not to resulting damage to other property. Expect $14,000 to be covered, subject to a fresh $1,000 deductible.
• Re-check the causation chain. If the burst occurred in the same failed supply line, the carrier can argue the second event was the continuation of the same excluded condition. Confirm with the plumber that the March 2 failure was a different fitting and a discrete event.
• The $6,000. Determine physically where the water came from. Water that escaped from the toilet supply and ran across the floor is not a backup; water that entered through the floor drain from the sewer lateral is. If the latter, the $5,000 endorsement limit applies and no deductible is owed on that endorsement under most forms.
• Anti-concurrent causation. If the form has it, do not let the February excluded condition swallow the March covered event; treat them as separate occurrences with separate deductibles and document the reasoning in the file.

Correct them on what a sublimit is. A sublimit is not a bucket of coverage that applies whenever mold appears; it is a cap on what is otherwise a covered loss. Coverage must first exist.

• Explanation to give the insured, in writing. (1) The February moisture is excluded as long-term seepage, so no mold coverage attaches to it. (2) Even if the water damage were covered, the most payable for mold would be $10,000, not $26,000. (3) The backup endorsement pays only for water that backs up through a sewer or drain - it is not a general mold endorsement.
• Show your work. Provide the leak-detection report and the exclusion text with the denial. Insureds accept limits they understand and litigate ones they experience as arbitrary.
• Consider whether any mold remediation is tied to the March 2 covered event. If remediation of the newly wetted area is needed, that mold is a consequence of a covered peril and is payable, subject to the same $10,000 cap - and the cap is a total for the policy period, not per occurrence, in most forms.
• Escalate with alternatives, not refusals. Offer a re-inspection with a certified industrial hygienist if the Rileys dispute the scope of remediation, and note the appraisal provision for valuation disputes while preserving the coverage position.
