Which of the following is not a sign of water issues in basements?

The situation regarding window wells is important to understand in the context of basement water issues. Typically, window wells are designed to direct water away from basement windows, preventing water from entering and causing damage. If the window wells are sloped properly and extend above the level of the window, they assist in safely draining water away from the structure.

When window wells extend below the windows, they can create a risk by allowing water to collect around the windows, leading to potential leaks and water intrusion into the basement. However, simply having window wells that are below the windows isn't inherently indicative of existing water issues unless there's evidence of water pooling or leakage. Therefore, among the options provided, this situation does not directly indicate a current or ongoing water problem, whereas the other signs—like rust at steel columns, loose floor tiles, and the need to keep storage off the floor—are clear indicators of past or present water damage or water intrusion.
