Risers & Extensions

Our custom fit polycarbonate window well risers and extensions offer excellent options for extending the height of your window well or effectively handling high window configurations.

The lip of your window well should be approximately 4-6 inches above the ground.  This well help prevent water from entering the well by spilling in right over the top lip.  When the lip of your window well is to close to the ground your well is more prone to take on water.  Therefor, this is one reason to raise the height of your window well with a wrap around window well riser.  The other reason is if the top line of your basement window sits above the lip of the window well.  In this case the main support of the well must be positioned above the top line of the window in order to not obstruct the window in any way.  While an angled riser (see below) may also be an option in this situation, it is not an option if your window is a crack out style and opens into the well.

Adding an angled riser to your window well cover is a great solution for your cover installation in two different situations.  First, when the top line of your window extends above the top lip of the window well, the main support of the cover must be positioned above the top line of the window in order to avoid obstructing the window in any way.  This results is a cover which starts above the window and is pitched forward away from the house.  However, even if the top line of the window is below the lip of the window well, an angled riser installation can be used when a pitched angle for the window well cover is desired for enhanced water and snow run off.  An angled riser is used on larger metal window wells and rectangular concrete wells.

Boxed Risers for

A boxed riser for a window well serves the exact same purpose as a wrap around riser, but is used when a wrap around riser cannot be used because the well is a square or rectangular shaped concrete, stone or wood constructed well.  Similar to the wrap around style riser, the box riser is designed to increase the height of the window well when the top lip of the window well is too close the ground or when the top line of the window extends higher than the top lip of the well and an angled riser cannot be use because the basement window is a crank our style that opens out into the well.

Vertical or Horizontal Extension

When your window is higher than the lip of your window well, a custom window well cover can be made where the main support along the building crosses in front of the window.  In an installation like this there is typically a gap between the main support of the window well cover and the window itself.  Closing this gap is necessary to keep leaves and debris out of the window well.  While this gap can be avoided by installing a window well riser, the window well cover extension offers economical option. Generally we recommend a vertical option so long as the window does not extend more than 10-12 inches above the top lip of the window well.  Beyond 10-12 inches we recommend a vertical well cover extension be used.  NOTE:  If your basement window extends more than 12 inches above the lip of your window well we highly recommend a window well riser be used instead of a window well extension.
