Things You'll Need
5/8-inch CDX plywood
3/8-inch carriage bolts with washers
Boarding up the windows in a primary or secondary residence that will be vacant for an extended period offers much-needed protection from a number of potential problems. Properly boarded-up windows helps protect the house from extreme weather and can deter vandals and thieves from damaging windows or breaking into the house to protect the home from looters or unwanted occupants after a severe storm. For added protection, you can bolt two-by-four lumber to the plywood covers.
Measure all sides of all windows, and locate the studs closest to those sides.
Video of the Day
Cut plywood with a circular saw so the sides are at least 4 inches past all sides of each window. Number or label each panel to note which window it fits.
Hold the plywood over the window, and drill pilot holes through the plywood and wall siding and into the studs every 16 inches.
Screw corrosion-resistant screws into the pilot holes, using the drill.
Cut four pieces of two-by-four lumber to the measured length of plywood for each window.
Position the lumber over the plywood sheet, with one board along each side edge and two spaced evenly in between. Drill 3/8-inch holes through the lumber and plywood in at least three places along the length of the lumber.
Secure the lumber to the plywood with carriage bolts.
When handling large sheets of plywood or working on a ladder, two people completing this job makes it much easier and safer.
