A window water well keeps water, ice, and snow from seeping into the window and flooding the basement.
Natural lighting and fresh air
Because of the window well, natural light can enter the basement, which will take it from dark and gloomy to radiant and inviting, which will create a more pleasant environment. Basements used to be characterized as dark and damp, but because of the benefits of window wells, you can not let the outside air into your home directly from the windows because of the window well. By doing this, you are allowing fresh air into the basement to help prevent mustiness. By allowing fresh air directly into your basement, it will remain naturally fresh and dry.
