Condo Plumbing Leak Claims: Navigate the Complexity of Shared Plumbing Systems

In a condo, a leak in a common-element pipe or building system is typically the HOA's responsibility under the master policy, while a leak inside your unit's plumbing is typically yours under your HO-6. The boundary between common and unit plumbing is one of the most disputed issues on a condo water claim, and carriers use the ambiguity to point each policy at the other. DCS documents the exact source and path of the water and files each portion of the loss under the policy actually responsible for it.

Both HO-6 and master policies cover water damage from a sudden, accidental plumbing failure — a burst supply line, a ruptured fitting — but exclude 'constant or repeated seepage or leakage' over time, and many Texas forms exclude seepage that has continued 14 days or longer. A slow drip inside a shared wall can run for weeks before it shows, so carriers reach for a 'gradual' label. DCS documents the discrete failure event with the failed component, a tight timeline, and moisture mapping to defeat that argument.

Standard policies pay to tear out and replace the part of the building needed to reach the system the water escaped from — opening a wall, ceiling, or floor assembly — even though the pipe repair itself is excluded. In a condo this access cost can cross into common elements or a neighboring unit, and it is one of the most frequently omitted items in a carrier first estimate. DCS scopes the access/tear-out on the correct policy so the right carrier pays to reach the failed line.

Mold or fungi remediation arising from a covered water loss is usually subject to a sublimit — commonly $5,000 to $10,000 — unless a higher mold endorsement was purchased. In a condo, delayed access to a neighboring unit or a common-area shutoff can let mold spread inside shared cavities before drying starts, and the bill blows past the cap quickly. DCS pushes for prompt, documented mitigation and identifies when a higher mold limit applies.

Even where mold itself is excluded or capped, the ensuing-loss doctrine generally extends water-damage coverage to mold that resulted from a covered sudden leak — the covered loss caused wet building materials, which caused the mold. DCS documents that causal chain (covered loss to wet materials to mold growth) so remediation is paid as part of the water claim, subject to any applicable mold sublimit.

When a building-wide water loss exceeds what the master policy pays, or triggers the master deductible, the HOA can assess each unit owner for their share. Most HO-6 policies include Loss Assessment coverage — commonly $1,000 to $50,000 depending on the policy — to reimburse that assessment, though base limits are often far too low for a large master deductible. DCS checks your Loss Assessment limit, documents the assessment, and pursues reimbursement under this coverage.

A backup of sewers, drains, or a sump pump — common in stacked condo buildings where multiple units share a drain stack — is excluded by the base water exclusion and covered only if a Water/Sewer Backup endorsement was added, often with its own separate limit. Many owners assume backups are automatically covered; they are not. DCS checks both the master policy and your HO-6 declarations for this endorsement before the carrier uses the exclusion to deny.

Adjusters frequently limit the scope to the visibly wet area, but water from a condo leak travels through shared wall cavities, under flooring, and into units below. Condo water losses are also often paid first at Actual Cash Value, with 'recoverable depreciation' released only after repairs are completed and invoiced — money many owners never go back to collect. DCS uses calibrated moisture meters and thermal imaging to document the full migration path and tracks the depreciation holdback on each policy through to recovery.
