How to Install Window Well Grates

The windows for a basement that are underground have wells that are dug out to allow sunlight into the rooms. These wells are dangerous if not covered by a grate or a plastic well cover because a person could step inside and twist an ankle. To keep from having mold build up due to the heat created by an enclosed plastic cover, a metal grate is your best option for a window well. The metal grate allows air flow while also keeping out unwanted animals.

  Set a 3-by-3-foot cardboard square over the window well.

  Trace the outline of the edge of the window well on the cardboard square, using a pencil.

  Remove the cardboard from the well. Set an adjustable window well grate on top of the cardboard.

  Align the grate on the cardboard so the grate loops are parallel with the edge of the outline that represents the wall of the house.

  Loosen the bolts on the four bars that are perpendicular to the loops of the grate, using a 7/16-inch wrench. There are four bolts on each of the middle bars.

  Stretch the loops to the left and right until the grate covers the entire outline on the cardboard. Tighten the bolts with the 7/16-inch wrench once the grate is stretched.

  Turn out the brackets to face away from the grate at a 90-degree angle. There are four brackets on the corners of the grate. Tighten the bracket bolts with the 7/16-inch wrench.

  Set the grate over the window well with the brackets over the edges. Tap 2-inch aluminum pegs into the holes in the center of the bracket, using a rubber mallet.
