How to Block Window Break-Ins With PVC Pipe

Although most windows have a locking mechanism, some people take other precautions, perhaps because the the mechanism has become worn and unreliable or just because they want to feel doubly protected. This can involve inserting an object such as a PVC pipe into the track of the window to keep it from opening. It's especially effective on windows at or near ground level. PVC pipe is inexpensive, and if you're planning to secure a window yourself, all you need, other than the pipe, are a few tools you have at home.

Tape measure
Pencil
Hack saw
Medium-grit sandpaper

Instructions

- 1
  Examine the window that you want to block to determine if it slides vertically or horizontally. Close the window fully, and lock it before proceeding. Otherwise, your measurements may be off.
- 2
  Place a tape measure at the top of the window track, and measure down to the top of the lower sash if your window moves vertically. If the window opens horizontally, measure from the side of the track to the center of the window, where the two sashes overlap.
- 3
  Lay a length of 1- or 2-inch-diameter PVC pipe on a work table, and use the tape measure to determine the proper length on it. Mark the length, using a pencil.
- 4
  Cut through the pencil line, using a hack saw. Hold the PVC pipe steady with one hand, and saw with the other.
- 5
  Go over the cut end of the PVC pipe with medium-grit sandpaper to smooth the rough edges.
- 6
  Insert the PVC pipe into the window frame, positioning it either vertically for a vertically sliding window or horizontally for a horizontally sliding window. Position the pipe close to the frame so that doesn't look unsightly. If the pipe does not fit, remove it, and sand the end down more.
