How Do You Fix a Sagging Window

To repair loose hinges on your window, simply use a screwdriver to tighten the screws that fasten the hinges to the frame and the window edge. If the window hinge screws won’t tighten but simply spin around and around, you may need to hire a professional for additional assistance.

What causes a window to sag?

If a window pane sags while the window frame remains level, the cause is most likely a bent hinge. Since a window’s hinge has to support a heavy window, some of them can bend over time and cause the window pane to be misaligned with the window frame.

Why does my top window keep falling?

A dropped window is an indicator of a bad, disconnected, or misplaced balance shoe. Each double-hung window in your home has four balance cartridges, two per jamb liner. If one of the balance shoes inside isn’t working properly, the sash will slide down when you attempt to raise it.
