Insurance Leak Detection & Cause-and-Origin Reports

Cause-and-origin assignments vary. Depending on the loss, the work may include visual assessment, moisture mapping, thermal imaging, acoustic testing, tracer gas, pressure testing, or subsurface mapping. We select methods based on the question being investigated and explain what the evidence can—and cannot—establish.

Assignment Scope and Records

Before the site visit, we identify the specific technical question, affected areas, relevant systems, known timeline, and who is authorizing the work. Available photographs, water-use records, repair invoices, plumbing reports, mitigation documentation, building plans, weather information, and prior claim materials can help establish context. Records supplied by others are identified as such; they are not treated as independently verified unless the assignment includes that verification.

Field Examination and Testing

The field work documents observed conditions and selects tests that are relevant to the suspected source. A plumbing loss may call for isolation, pressure observations, acoustic testing, tracer gas, or line locating. A water-intrusion investigation may instead emphasize moisture distribution, weather exposure, flashing, penetrations, and controlled testing. Methods are not used simply because they are available; they are chosen when they can answer the assignment question without unnecessary disturbance.

Analysis and Report Method

The report distinguishes observations, measurements, information provided by others, and professional interpretation. It explains the source or failure mode most consistent with the available evidence, discusses reasonable alternatives when they remain possible, and records material limitations such as inaccessible assemblies, altered conditions, completed repairs, intermittent symptoms, or testing that could not be performed.

Important Limitations

A cause-and-origin report is technical documentation, not a coverage opinion, legal conclusion, repair estimate, engineering design, or guarantee of claim payment. The insurer interprets the policy and makes the coverage decision. When concealed conditions, structural questions, code issues, microbial growth, or specialized repair design fall outside the assignment, evaluation by the appropriate licensed or qualified professional may still be required.
