Priya's Shower Wall: Seepage, Mold, and Code Upgrades
Priya's 1978 split-level in Chesterfield is insured on an HO-3 (10 00 edition) with Coverage A of $350,000 and a $2,500 deductible. In March the tile on her hall bathroom wall popped loose and the drywall crumbled. A plumber traced the water to a corroded copper fitting on the shower supply line and wrote on his invoice that the fitting 'failed suddenly on March 3.' Priya told the adjuster she first noticed a soft spot 'around September' and put a rug over it. The contractor's estimate breaks down as $18,000 to repair drywall, subfloor, vanity and flooring; $2,000 to tear out and replace the wall to reach the fitting; $14,000 for mold remediation; and $5,000 for the wider door, GFCI outlets and arc-fault breakers the county now requires in a rebuilt bathroom.
1. Determine coverage for each of the four cost buckets. Explain the reasoning you would put in the denial or payment letter.
Read the worked answer
All four buckets are excluded, on the present facts.
Why. The HO-3 water damage exclusion bars loss caused by 'constant or repeated seepage or leakage of water over a period of 14 days or more' from within a plumbing system. The evidence establishes far more than 14 days: Priya's own statement that the soft spot appeared 'around September,' plus the staining pattern and the corrosion on the fitting. The plumber's 'failed suddenly on March 3' line describes the moment the fitting finally let go; it says nothing about when water began escaping. An adjuster takes the insured's recorded statement over a plumber's conclusory invoice note.
Bucket by bucket.
- $18,000 drywall/subfloor/vanity/flooring - excluded. The form uses anti-concurrent-causation wording, so the excluded seepage also takes the resulting rot and staining; there is no ensuing-loss carve-back for this peril.
- $2,000 tear-out to reach the fitting - excluded. Tear-out coverage is additional coverage triggered only by a covered water loss, and the plumbing system itself is never covered. No covered loss, no tear-out payment.
- $14,000 mold - excluded twice over: the seepage exclusion, and the mold/fungus exclusion, which is subject to a $10,000 per-occurrence sub-limit only when the underlying loss is covered.
- $5,000 code upgrades - not payable. Ordinance or law coverage in the 10 00 form is limited to 10% of Coverage A ($35,000 here) but it pays increased cost of construction on a covered loss. With no covered loss there is nothing for it to attach to.
Note for the file. The 10% ordinance-or-law amount is part of, not in addition to, the Coverage A limit, and the mold sub-limit likewise sits inside Coverage A.
2. Assume instead that the evidence had shown the fitting truly let go on March 3 with no prior leakage. Calculate what the insurer pays.

Covered loss: accidental discharge of water from a plumbing system.
| Item | Amount | Treatment |
|---|---|---|
| Drywall, subfloor, vanity, flooring | $18,000 | Covered in full |
| Tear-out to access the fitting | $2,000 | Covered - tear-out is payable where the water damage is covered |
| Mold remediation | $14,000 billed | Capped at the $10,000 mold sub-limit |
| Code upgrades | $5,000 | Covered under ordinance or law; available room is 10% × $350,000 = $35,000 |
Subtotal before deductible: $18,000 + $2,000 + $10,000 + $5,000 = $35,000. Less the $2,500 deductible = $32,500 payable.
Judgment points a grader will look for:
- The mold cap is a sub-limit, not an extra $10,000 stacked on top of Coverage A. The $4,000 of mold above the cap is uninsured.
- Ordinance or law is not discretionary - the HO-3 pays it automatically, and $5,000 is well inside the $35,000 available.
- The deductible applies once to the occurrence, not once per coverage bucket.
- The damaged vanity and the fitting itself are not covered; only the resulting water damage to the structure is.
3. How would the outcome differ if the property were insured on a DP-1 dwelling fire policy on an actual cash value basis with no ordinance-or-law endorsement?
Read the worked answer
The claim would almost certainly pay nothing.
Perils. A DP-1 is a named-peril form: fire, lightning, internal explosion, and whatever extended coverage perils are added. Accidental discharge of water from a plumbing system is not a DP-1 peril. There is no coverage for the water damage, the tear-out, or the mold, regardless of whether the leak was sudden.
Valuation. Even if a covered peril were involved, ACV settlement means deducting depreciation. A 1978 bathroom's 47-year-old subfloor, vanity and flooring would depreciate to a fraction of the $18,000 replacement estimate, so the insured would absorb most of the loss personally - the opposite of the HO-3 replacement-cost result.
Ordinance or law. There is no ordinance-or-law coverage at all on the DP-1 without an endorsement, so the $5,000 of code upgrades is uninsured in every scenario.
Mold. No mold sub-limit applies because it is not a covered peril in the first place.
Takeaway for the insured. The HO-3's broad-form water peril and replacement cost are worth real money on a 1978 house with original plumbing. If Priya had been on a DP-1, the correct advice is to upgrade the form and add water backup and ordinance-or-law endorsements - but that advice cannot resurrect a loss that has already happened.
