Does Home Insurance Cover Water Damage?
Sudden damage, like a burst pipe, is usually covered. Gradual leaks, sewer backup and flooding usually aren't unless you added that coverage.

Sudden vs. gradual leak
A pipe that bursts overnight is sudden and accidental, the kind of loss a standard policy pays for. A pipe that's been dripping behind a wall for months is gradual, and insurers treat that as a maintenance failure the homeowner should have caught, so it's excluded.
Sewer backup is separate
Water or sewage backing up through a drain or sewer line isn't covered by a standard policy at all. It's usually sold as an endorsement you add for an extra amount. Check your declarations page to see if you already carry it, and for what limit.
Flood needs its own policy
Rising water from outside the house, like a storm surge or an overflowing river, is flood damage, and no standard homeowners policy covers it. Flood insurance is a separate policy entirely, through the National Flood Insurance Program or a private flood insurer.
Mold follows the cause
Whether mold is covered usually depends on what caused it. Mold from a sudden pipe burst you reported quickly is often covered, sometimes with a lower limit. Mold from a slow leak left unaddressed is typically treated as a maintenance issue and denied.
Sewer backup and flood aren't automatic
If your policy doesn't already carry sewer backup coverage, or you're in a flood zone without flood insurance, water damage from those causes falls entirely on you. Compare quotes to see what adding them costs.
What to do in the first hours after you find water
Stop the source if you can. Shut off the water main for a burst pipe, shut off the appliance, or shut off the water heater. Every hour water keeps flowing is more damage, and it's also harder to argue the loss was sudden if you let it run.
Photograph everything before you move or dry anything. The water itself, the wet flooring and drywall, the source of the leak, and any damaged belongings. If you can show a pipe fitting that failed or a water heater that split open, that photo is often what separates a paid claim from a denied one. Keep damaged items instead of throwing them out until the adjuster has seen them or told you it's fine to dispose of them.
Call your insurer or start the claim as soon as the water is stopped, not after you've dried out the house and patched the wall. A gap of weeks between finding water and reporting it gives the insurer room to argue you let a sudden loss turn into a maintenance problem. Most policies also require you to prevent further damage, which usually means drying the area, running fans or a dehumidifier, and not waiting on repairs that stop more water from spreading.
Get a plumber or contractor to document the cause in writing, especially for anything behind a wall or under a floor where the source isn't obvious. An adjuster deciding between a sudden pipe failure and a slow, long-term leak often relies on what the repair person found when they opened the wall. If the damage involves a finished basement, flooring, or anything electrical that got wet, a written estimate for each separately makes the claim easier to settle and harder to shortchange.
What a standard policy actually pays for once a claim is approved
Coverage for water damage splits into pieces, and it helps to know which one applies before the adjuster shows up. Dwelling coverage pays to repair the structure itself. That includes the drywall, flooring, cabinets, and framing that got wet. Personal property coverage pays to replace or repair belongings the water ruined, like furniture, rugs, and anything stored on a basement floor. These are two separate limits on your policy, and a bad water loss can hit both at once.
What a lot of homeowners miss is that fixing the water damage and fixing the thing that caused it are treated differently. If a pipe bursts, your policy typically pays to tear out and replace the soaked flooring and drywall around it. It usually does not pay to replace the pipe itself, since that's considered normal upkeep rather than damage from a covered loss. The same split applies to a water heater that fails. The flood it caused is covered, but the water heater itself often isn't, unless you've added equipment breakdown coverage.
Your deductible applies here the same way it does to any other claim, as a flat dollar amount you pay before the insurer covers the rest. Some policies also carry a separate, higher deductible specifically for water or sewer backup claims, so check your declarations page rather than assuming your standard deductible applies. On a moderate water loss, a higher water-specific deductible can mean the claim barely clears it, which is worth knowing before you file.
Additional living expenses coverage is the piece people forget until they need it. If the water damage makes part of the house unlivable, like a bathroom demo that also knocks out your only working plumbing, this pays for a hotel or short-term rental while repairs happen. It's usually a percentage of your dwelling coverage, not a flat amount, and it has limits on both the dollar total and how long it lasts. If you're displaced for more than a few days, ask the adjuster directly what this piece of your policy covers, since it isn't always volunteered.
Before you need it
Find your declarations page and look for sewer backup coverage. Check what deductible applies to water claims too. If either one is missing or lower than you'd like, see what adding it costs.
