Window boxes are a beautiful way to add color and life to the appearance of your home. Window boxes come in a variety of shapes and sizes. The type of window box you purchase will determine how to hang them. Many people opt for window boxes that have no visible brackets. This type of window box provides a more clean appearance because it looks like it's built into your home, rather than being a last-minute addition.
Attaching To Wood Home
Locate and mark the studs under the window from inside the house. Use a stud finder to identify where studs are and transfer their location to the windowsill using a pencil. This way you can easily see where the stud locations are from the outside.
Hold the window box under the window from outside the house. Position the window box under the window and transfer the stud location to the window box. Set the box down after you have marked the stud location onto the window box.
Measure the depth of the box and divide it by half. Using a drill and a 3/8 drill bit, make holes for your wood lags at the stud marks to half the depth of the window box.
Set the window box back under the window with the assistance of a helper. Mark the pre-drilled holes in the window box to the outside wall of the home. Put the window box back down.
Drill pilot holes in the outside wall for attaching wood lags.
Lift the window box back into place under the window. Insert a wood lag bolt into each pre-drilled hole and start to tighten them down with a socket wrench.
Set a level on top of the box to make sure the window box is level. Tighten the lag bolts down securely.
Attaching To Brick Home
Mark four hole positions for the attaching bolts evenly across the back of the window box.
Drill four 3/8-inch holes through the back of the window box using a drill.
Set the window box under the window and center it. Mark the hole locations on the wall of the home with a pencil.
Drill holes into the masonry at the marked location with a 5/8-inch masonry drill bit. Insert a 5/8-inch shield into each hole for the lags to attach to.
Lift the window box into position under the window, and insert the lag bolts into the holes and into the shields. Tighten the lag bolts while checking how level the window box is.
