How to Get a Jammed Window Back Up

When you open your windows, you fill your home with fresh air and warm sunshine. But sometimes, windows get stuck or jammed, and they won't open no matter how hard you try. Windows get stuck for a variety of reasons. For example, when the humidity changes, the window sashes may warp, making it difficult to open the window. Also, if you never were able to open a certain window, someone may have painted it shut accidentally.

Putty knife
Hammer
Pry bar
Block of wood

Instructions

- 1
  Slide a sharp utility knife in the gap between the window's frame and lower sash. Move the knife around the seam. If the window was painted shut, this breaks through the paint that dried in the seam, allowing the window to open. If this doesn't work on the inside part of the window, repeat the process outside.

  Stick a flexible putty knife blade between the window's frame and lower sash from inside the building. Tap the knife handle with a hammer as you move the knife around the sash. This loosens most stubborn windows.

  Go outside. Stick a pry bar under a corner of the windowsill. Place a small wooden block under the pry bar. Push down on the pry bar to lift the window up. Move the pry bar across the bottom of the windowsill to loosen it fully.
