Description

The metal window well extensions are a shorter version of the standard wells. Usually, they are about 12″ tall. They are installed outside of an existing window well, enabling the grade to be raised at the foundation wall.

The window well extenders will adjust your metal well’ height to accommodate your basement’s depth for a safe and code-compliant fire exit. With one of our lovely window well scenes, it will bring light, color, and style to any home design.

Why and when are window well extensions needed?

  1. In short – so that water will flow away from the building. Window well extensions are necessary to help correct grading around established homes to compensate for the ground settling.
  2. They are needed when the basement window extends higher than the top edge of the window well.
  3. They are needed when the window well is not at least two inches above the landscape grade.

Do window wells work?

Yes! The metal well extensions can be the difference between a wet and a dry basement!

No. The window well risers are not egress compliant by themselves. If the original well is egress-compliant, then the extension will be too.  

If ordering a well for bedroom egress, check with your local building inspector to verify your code requirements before ordering or installing any window well. 

  • Well depth must be 8″-12″ below the lower sill of the basement window
  • Well depth (above ground) must allow the well to extend a minimum 2″-3″ above grade (soil level)
  • Well width must provide at least 2″ on either side of the basement window.

If you are not 100% certain about how to measure your metal window well opening, you can always use our specially-developed well measuring guide.
