What are the visual signs of water damage?

Discoloration may also occur in the corners where the walls meet the ceilings and floors.

The paint along the ceilings can reveal when water damage has occurred. Painted ceilings with water damage show cracks, bubbling, or flaking. Peeling paint is another visual warning sign of water damage. When drywall is affected by water damage, it produces the same symptoms.

Homeowners may discover a pool of water under a pipe. If the puddle of water returns after cleaning, it is a clear indication of a pipe leak. Similarly, pools of water elsewhere in the home that keep returning are signs of a leak and should be promptly repaired.

A home may produce all sorts of sounds. One sound that homeowners should not expect to hear is running water. Hearing a dripping sound or the sound of rushing or running water suggests water damage. However, these sounds can occur within a functional system; so, check for changes in sound.
