Homemade Basement Window Security Ideas


Basement windows can provide an easy access point for burglars. The available options from home security system manufacturers are often too expensive to fit into your budget. Homemade basement window security ideas can provide a creative, inexpensive and flexible approach.


  • You can fit a metal grille over your basement window to provide security. This allows light and air through but deters burglars. Several styles are available, including perforated, expanded or wire mesh. Measure the window from the outside. Add about 4 to 6 inches to the width and height and buy a piece of grille to that size. Drill fixing holes in suitable places in the wall around the window. Then screw the grille in place with long screws.


  • Window bars improve security but can be expensive. You can improvise a similar principle using a metal headboard, which is essentially a set of bars welded together in a decorative way. You can often pick these up at markets or thrift stores. Use suitable cup brackets to fit the headboard in place. Having drilled holes through the wall, fix the cup brackets in place over the posts of the headboard, near the top and bottom, using long screws. One major drawback to steel bars or grilles is that they can prevent you from having an exit access in the event of a fire, which could prove tragic.


  • You could grow a hedge of holly, hawthorn and other spiky, prickly or thorny plants in the soil outside the basement window to form a virtually impenetrable plant security screen. The plants will look good from the inside and not make you feel like you live in a prison. Few burglars want to risk getting scratched, pierced and cut by plant leaves and spikes, and it's probably too time-consuming for them to get them out of their way.

Other Ideas

  • You could buy a big dog and let him sleep in the basement. Few burglars will risk trying to break into a basement if they hear a big dog growling inside. You could fix a sturdy wooden member or two across the casing on the inside. Measure the distance between the left and right faces of the interior casing. Saw a length of timber to that size and hammer it into the casing between the faces. You might also want to consider bricking up the window, if it's proving to be more of a nuisance than a benefit. But again, this could leave you trapped in the basement in the event of a fire or other emergency that warrants your fleeing quickly.
