Water damage
Appliance leak damage in Castle Rock, Colorado
Most appliance leaks are small until they are not. A cracked hose on a washer can empty into a laundry room for as long as nobody is home.
Calling early helps.

Shut off the supply to that appliance
Washers, dishwashers and icemakers have their own shutoff valves. Closing the one behind the appliance stops the leak without cutting water to the whole house.
If you cannot find it, close the house shutoff near the meter. The Town of Castle Rock says that is the valve to use, not the one at the street.
Slow leaks hide
A leak behind a dishwasher or under a water heater may run for weeks. The floor can feel solid while the subfloor underneath is wet. Soft flooring, a musty smell or a stain on the ceiling below are the usual signs.
Sudden or gradual matters to insurers
Homeowners policies often cover water damage that is sudden and accidental and exclude damage from long-term seepage or a lack of maintenance. Wording varies by policy. The Colorado Division of Insurance publishes plain-language guidance on what policies do and do not cover.
Water is spreading. Call now.
The call goes to an independent restoration contractor who serves Douglas County. Calling early matters because wet drywall and subfloor start to break down quickly.
