The Weeping Supply Line

Andre and Lisa own a 1998 home in Houston insured on a Texas HO-3: Coverage A $300,000, mold remediation sublimited at $10,000, additional living expense at 30% of Coverage A, ordinance or law at 10% of Coverage A, and a $2,500 deductible. A copper supply line behind the master-bath wall had been weeping for months; Lisa noticed a stain in January and did nothing. On March 12 the line ruptured and flooded about 900 square feet of flooring. Opening the wall revealed heavy mold in the framing - $34,000 to remediate - and $46,000 to repair the flooring and drywall. The family rented an apartment for three months at $2,900 per month while continuing to pay their $2,700 monthly mortgage payment. The city then required the entire branch line to be replaced with PEX, $14,000 total, of which $4,000 was the ruptured section.

1. How much of the mold remediation and the tear-out should the carrier pay?

Read the worked answer

Separate the loss into two causes and apply the exclusions in sequence.

1. The seepage damage is excluded. The policy excludes constant or repeated seepage or leakage over 14 days or more. Lisa's January stain establishes months of weeping, so deterioration from that slow leak is not covered.

2. The March 12 rupture is a sudden discharge - covered. The water that escaped when the line burst is a sudden and accidental discharge, and ensuing damage from it is payable. The doctrine of ensuing loss means the exclusion for the seepage does not swallow the burst.

3. Mold sits under a dollar sublimit, not an exclusion. Mold resulting from a covered peril is payable only up to the $10,000 sublimit and only for mold attributable to the covered rupture. Mold attributable to the excluded months of weeping is not payable at all. Realistically the remediation invoice must be apportioned by cause; if it cannot be, the file supports paying the sublimit and no more.

4. Tear-out is separately covered. The cost to tear out and replace building materials necessary to access the failed plumbing is covered (often as "reasonable repairs" and access coverage), but the cost to repair or replace the plumbing system itself is not.

Conclusion: pay $10,000 of mold remediation and the covered access/tear-out costs; deny the plumbing repair and the seepage-related deterioration.

2. What is the maximum additional living expense payable, and how should the $2,900 monthly rent be measured?

Read the worked answer

Three gates must all open before ALE pays: the loss must be covered, the home must be unfit to live in because of it, and the expenses must be necessary and reasonable.

  • Covered/ unfit: the flooded flooring and mold make the home uninhabitable during repair. Gate open.
  • Limit: 30% × $300,000 = $90,000. The $8,700 claimed is nowhere near the cap, so the cap does not decide anything.
  • Measure: ALE pays the increase in living costs over normal expenses, not the rent itself. Because the mortgage payment continues unchanged and is not a duplicated expense, the full $2,900 rent is generally the increase - unless the family saved on utilities, lawn care, or other costs they no longer incur, which should be netted out.

Duration: limited to the reasonable time needed to repair or permanently relocate. Three months for 900 square feet of flooring plus mold remediation is defensible; if the contractor's schedule says six weeks, the adjuster can cap at six weeks unless the insured can show why the delay was unavoidable.

Settlement: roughly $8,700 less any demonstrated savings. Do not pay the mortgage principal or escrow as ALE - those are not living expenses, and paying them converts a first-party benefit into a debt service subsidy.

3. The city requires the full branch line replaced with PEX at a cost of $14,000, of which $4,000 is the ruptured section. What is covered?

Read the worked answer

Ordinance or law coverage is triggered by the code requirement, but it is limited in two ways: by scope and by sublimit.

  • Sublimit: 10% × $300,000 = $30,000. The entire $14,000 fits comfortably.
  • Scope - the real issue: the coverage applies to the increased cost of repairing the damaged portion of the property to comply with code. It does not fund a voluntary upgrade of undamaged components.

Apply that:

  • $4,000 ruptured section: this is the damaged property being rebuilt to code. Covered, subject to the deductible/limits.
  • $10,000 undamaged remainder of the line: the city is forcing a system-wide upgrade that the insured benefits from permanently. This is not the increased cost of repairing damaged property; it is an uninsured improvement.

Practical note: the plumbing itself was never covered (repair of the system is excluded), so the answer depends on whether the $4,000 was already allocated to the access/repair of the damaged wall area. Allocate the invoice by line item before paying - a single "replace branch line" invoice is the classic way this coverage gets overpaid. Document that the ordinance or law attachment exists on the declarations page; many HO-3s carry it, but it must be confirmed, not assumed.
