Why This Page Exists Before Any Other
In this region, the difference between a recoverable loss and a mortgage-on-the-basement one is usually three decisions made in the first day: whether the water's source was documented before anything moved, whether the insurer was notified before anything was torn out, and whether the work was priced on paper with readings to back it. Those are not cleaning questions; they are claim-shape questions. Yet most water damage content in Ontario skips them entirely, which is why homeowners learn this material from an adjuster at the worst possible time.
Windsor-Essex raises the stakes. This is one of the most flood-documented corners of the province, with a storm history that has tested the city's drainage repeatedly, and insurance products have adapted around that reality: overland flood and sewer backup endorsements carry visible weight here, and insurers price them against the region's record. A guide that never mentions endorsements would be quietly useless in this market.
So this is the honest boundary: we clean up and dry out, we document professionally, and we do not interpret policies or decide claims. Everything below is general education about how the picture typically looks. Your policy's wordings and your insurer's answers override every line on this page.
