The Best Window Well Covers Option

Window well covers prevent rain and snow from collecting in window wells, which can cause water to pool against your foundation and make its way into your home’s interior. The layer of protection that a window well gives can save you from costly damage and repairs. And water isn’t the only protection these covers offer; the best window well covers also keep out rodents, prevent children from falling into the wells, and stop leaves and debris from collecting by your windows.

Window well covers come in different shapes and lengths to fit window wells of various sizes. Materials vary also, from polycarbonate to plastic. Certain types and sizes may work better for your window wells, depending on climate, their size, and what you need to keep out of the wells (like pets or children). You also have to consider the cover’s translucency. Opaque covers block out light, which may not be a problem in an unfinished basement. However, if the basement functions as a rec room, you’ll need as much light filtering in as possible.

Our Top Picks

A window well cover should have a snug fit that prevents leaks and rodents from entering the window wells. Some are also strong enough to act as a barrier to prevent children or pets from falling in the well. These top picks include window well covers of different sizes and shapes to help you find one that meets your needs.

Best Overall

The Amerimax Home Products Translucent Area Well Cover offers protection from the elements and a barrier for pets and children. It fits both plastic and metal rounded window wells with a width of up to 37 inches and a depth of 16 inches.

A 500-pound maximum load capacity means children won’t fall through it if they happen to land on the window well. The underside has a recessed groove to fit over the well’s lip and stay in place. The durable, heavy-duty plastic withstands sun, wind, and rain damage. However, despite the name, this model isn’t completely translucent. The heavy-duty build only lets in about 25 percent of natural light.

Durable polycarbonate lets light filter in yet keeps the cover lightweight, so it’s easy to install and maneuver if you need to access the window well. However, it’s not load-bearing, so it’s not the best option if you want to keep children or pets out of the window well.

Best Circular
