How Window Well Leaks Cause Basement Flooding

The window well refers to the area outside of the basement window, which keeps the surrounding dirt from entering the home and drains rainwater away. When any portion of a basement window is below grade, window wells are required. If the window well drain gets clogged, the basement window well can fill up with water and leak in through the window causing a flooded basement. Here are some common problems that may be the reason your window well is leaking water into your basement.
Window Well Leaks Cause Basement Flooding


Common Problems with Window Wells

How does a window well leak happen? Homeowners can damage their basement by making changes to the windows in the basement. Enlarging existing window wells, or installing a new window without excavating to the weeping tile to ensure proper drainage, can lead to flooding. Heavy rain can overflow water into these areas and into your basement. Problems can also occur if window wells were not properly fastened to the wall. During the winter, when the ground freezes and swells, it may eventually push the window well upwards causing the earth to flow underneath the well and into the drain. If the drainage system fails in that area, water overflow can happen.

Here are some common signs that your window well is not functioning as it should.

  • Sediment contamination of the gravel in a window well
  • Insufficient drainage or blockage (leaves, dirt, silt, melted snow, etc.)
  • A poorly draining window well
  • Poor installation
  • Wrong window well sizing
