Water that comes into contact with sparks or electrical wires can instantly ignite flammable materials. Additionally, any type of exposure to water can cause wires and other electrical components within your home to corrode. When assessing categories of water damage, it's important to know that even a small amount of moisture near wiring could cause sparks that lead to a fire.
