Does homeowners insurance cover water damage?
Nearly every argument about a water claim turns on the same two questions. Did the water arrive all at once or over months? And did it come from inside the building or in from the ground outside?
Sudden and accidental versus gradual
The wording is usually built around the sudden event: a supply line that lets go, a tank that splits. Slow seepage over a season tends to be classified as upkeep rather than loss, on the argument that a reasonable owner would have noticed it.
Which puts enormous weight on duration. The same failure discovered in week one and discovered in April after running since November produces two very different conversations, even though the pipe broke in exactly the same way.
Flood is a separate thing entirely
Water that arrives across the ground: a creek over its banks, tidal water pushed inland along the Chesapeake, runoff finding a way in at grade, normally sits outside a standard homeowners policy altogether. Where it is covered at all, it is covered by 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
Record it before you touch it. Stills and video of the standing water, the source if you can see it, the contents, and how far it reached up the walls and across the floor. Hold on to the ruined material until somebody has looked at it, where that is practical. And keep every receipt for whatever you spend limiting further damage: most policies require you to make that effort, and many pay it back.

If there is water in the home right now, that changes the priority: start here instead.
No two policies read alike, and the only authorities on yours are the document itself and the company that issued it. Nothing written here interprets any contract.
