Categories of water damage

Water damage gets sorted into three numbered categories. That number gets read three different ways: by the crew handling it, by the adjuster reviewing it, and by you, the person living with it.

The three categories, briefly

Category 1 is clean water, straight from a supply line or a fresh appliance failure. Category 2 has picked up some contamination along the way. Category 3 is the most contaminated tier, the kind tied to sewage or outside floodwater. Time works against the number, not for it. Water that started clean can climb to category 2, sometimes even category 3, if it sits untreated long enough.

What the crew reads into the number

The category decides what gear the crew wears. Category 1 needs basic care and standard precautions. Category 2 and 3 call for more protection, since the water itself carries more risk to anyone handling it directly.

What the adjuster reads into the number

The category shapes how a claim gets scoped. A higher category usually means more material comes out entirely, not just gets dried in place. That changes the estimate an adjuster reviews and, often, what it costs to settle.

What it means for what’s salvageable

For you, the number decides what stays and what goes. Clean water gives soft materials a real chance at drying out fully. Contaminated water usually doesn’t, even when a piece still looks fine on the surface.

Where this shows up elsewhere

Sewage backups sit at the very top of this scale, and the sewage cleanup page deciphers what that top tier actually changes about a job. Water that arrived from outside your house carries its own contamination question too, one the flood cleanup page previews in more depth. How long any of this actually takes to dry, the subject of the drying time guide, depends partly on this same number.

You describe it, the category gets confirmed on site

You describe what happened when you call: what leaked, how it looked, roughly how long it sat. The category itself gets confirmed once someone’s actually looking at the water in person, not guessed at over the phone beforehand.

What the number decides for everyone in the room

The category is one measurement, but it drives three different decisions at once: how the crew works, how the adjuster scopes the claim, and what you can reasonably expect to keep. Get the number right early, and those three decisions line up together instead of colliding later.
