What Are the Signs of Water Damage Under a Kitchen Sink?

Visible Leaks and Dampness

The most obvious clue is a visible leak. You might see water dripping from pipe connections or the base of your faucet. Even small drips can cause significant damage over time. Feel around the pipes and under the sink basin. If you notice any persistent dampness, it’s a red flag.

Unpleasant Odors

A persistent musty or moldy smell emanating from under the sink is a strong indicator of hidden moisture. This smell often means that mold or mildew has started to grow. These growths thrive in dark, damp environments. Don’t mask the smell; investigate the source.

Cabinet Floor Issues

Peeling Paint and Damaged Finishes

Damage to Surrounding Areas
