Building envelope: Window well covers
Help prevent water buildup and foundation damage
Window well covers can prevent debris accumulation causing slow-draining wells
Window wells are plastic or metal products that surround a basement window to create a gap between the window and the ground. This allows sunlight in and/or creates an emergency exit from the basement. Window wells should have proper drainage and be cleaned regularly to prevent water accumulation. Window well covers can help prevent debris accumulation inside basement window wells and reduce accumulation causing slow-draining wells.
What to look for
- A custom-made window-well cover will fit better.
- Durable window-well covers made of polycarbonate plastic are less likely to be damaged and will be needed to be replaced less frequently.
- Hinged covers will be required if the window serves as an emergency exit.
- Should sit at least 10 to 15 centimetres (4 to 6 inches) above the ground.
Things to consider
- Window well covers are not a replacement for having a proper window-well drainage system that is professionally installed.
- Take other measures around your home to prevent basement flooding, including installing a sump pump, a backwater valve and disconnecting your downspouts.
