Does homeowners insurance cover water damage?
Most of the disagreement between homeowners and insurers about water comes down to two distinctions: whether the water was sudden, and whether it came from outside the house.
Sudden and accidental versus gradual
Policies are generally written around water that arrives suddenly — a supply line that lets go, a tank that fails. Water that seeped slowly over months is commonly treated as a maintenance issue rather than a covered loss, on the reasoning that it was foreseeable.
This is why the length of time a leak ran matters so much, and why a leak found early is a different conversation than the same leak found in the spring after running all winter.
Flood is a separate thing entirely
Rising surface water — a river out of its banks, storm surge, water coming across the ground and into the house — is generally excluded from a standard homeowners policy and covered, if at all, under separate flood insurance.
That distinction is not academic in this part of Maryland. Homes along the Patapsco through Ellicott City, the Gwynns Falls below Catonsville, and the tidal edges of Dundalk and Essex have taken water from outside more than once.
Document before anything moves
Photograph and video everything while it is still wet and still where it is — the water, the source if visible, the contents, the extent on walls and floors. Keep damaged material where practical until it has been seen. Keep receipts for anything spent to stop further damage, which most policies expect you to do and many will reimburse.

Policies differ and only your own policy and your insurer can tell you what is covered in your situation. Nothing on this page interprets any policy.
