The main purpose of a basement window well cover is to allow ventilation and sunlight into the darker areas of the basement. Moreover, a basement window well cover is also suitable for use as a waterproofing system, as it can prevent water infiltration in the basement, notes Seepage.com.
Other reasons to install a basement window well cover include keeping away animals from the basement and preventing leaves and other debris from accumulating in the space. As most basement window well covers are custom-made, they can seal a window completely for enhanced protection. A well-sealed basement window well cover is also energy-efficient, as it prevents heat from escaping from the basement.
