How to Install Security Doors


Security is a priority for most homeowners. If you're looking for a way to beef up the security of your home, a security door might be the answer. They come in a variety of decorative styles and colors, so finding one that will fit your décor should not be a problem. Security doors may superficially resemble old-fashioned screen doors, but their solid construction makes unwelcome entry nearly impossible.

Things You'll Need

  • Pre-hung security door
  • Helper
  • Level
  • Socket wrench set
  • Drill
  • Drill bits
  • Protective eyewear
  • Set the pre-hung security door and frame in place, centering it over the existing door on the outside. You may need to remove existing trim around the door and install the door against the siding. The frame must be flat against the house for sturdy attachment.

  • Using the pre-drilled holes in the security door frame as guides, mark the locations of drill holes, then set the door aside.

  • Drill straight and level through the exterior and interior walls. Have your helper hold a level against the wall to help you guide the bit in straight.

  • Put the security door in place and set the screws, running them all the way through to the inside. Secure with a washer and a nut on the inside.

  • On the inside, use a trim around the door frame to cover the bolts and create a professional, finished appearance.

Tips & Warnings

  • Get a helper; this is not a one-person job. The door will be heavy and difficult to handle alone. Security doors may be in stock in some large home improvement stores, or you can special order them online or through most stores that carry doors. Security doors may be installed without going all the way to the inside using lag bolts, but it is a less secure method.
  • Always wear protective eyewear when working with power tools.
