Window Sashes Falling Down & Putting Window Pivot Pins Back Into The Balances

There are several telltale signs that your windows pivot pins are out of the balance:

Difficulty Operating the Window:

  • Sticking or Binding:  This is a common symptom. Windows that become difficult to open or close smoothly, requiring excessive force, could indicate a balance issue.

  • Uneven Movement:  The window sash might move erratically, tilting or sagging to one side as you raise or lower it.

  • Slamming Shut:  Window sashes falling down with unexpected force is a safety hazard and points towards a malfunctioning balance system that can't properly control the sash weight.

Improper Window Positioning:

  • Sash Won't Stay Open:  If the window struggles to stay open at a desired position and constantly wants to slide down, it's likely the balances aren't strong enough to support the sash weight.

  • Window Pops Open Unexpectedly:  Conversely, a window that pops open with minimal effort or drafts shut unexpectedly could signify an overactive balance system.

Visual Inspection:

  • Tilted Sash at Rest:  Take a close look at the window sash when it's closed. Does it appear level, or is it tilted slightly at an angle? This can indicate a balance weakness on one side.

  • Broken or Damaged Balances:  In some cases, you might see visible damage to the balance mechanisms themselves, such as cracked casings or loose components.

If you experience any of these signs, it's a good indication that your windows are out of balance. You can attempt to troubleshoot the issue yourself by checking the pivot pin connections or cleaning the window tracks. However, for more complex problems or if you're uncomfortable with DIY solutions, consider giving The Window Store a call for proper diagnosis and repair.

Putting The Pivot Pins Back Into The Window Balance

Putting window pivot pins back into balances requires a little finesse due to the tension on the balance system. Here's a breakdown of the steps:

Tools You'll Need:

  • Flathead screwdriver


  1. Unlock the Shoe: Locate the shoe (the piece attached to the window frame that holds the pivot pin). There's usually a small, U-shaped metal clip on the shoe. Insert the flathead screwdriver into the opening of the U-clip and gently pry it down (be careful, the spring-loaded mechanism can snap back).

  2. Adjust Shoe Height (Optional): If the window sash was removed completely, you might need to adjust the shoe height for proper alignment. With the U-clip disengaged, you can move the shoe up or down slightly. Make sure both shoe positions are level with each other.

  3. Engage the Shoe: Once positioned correctly, rotate the U-clip back upward until it clicks back into place, locking the shoe.

  4. Reattach Pivot Pin: Locate the pivot pin on the window sash (the metal pin that fits into the shoe). With the sash at a slight angle, carefully guide the pivot pin into the opening of the shoe. The sash might need a little wiggling to fit properly.

Here are some additional tips:

  • Be cautious when handling the U-clip, as the balance system is under tension and can snap back with force.

  • If you're unsure about the specific mechanism of your window balance, search online for "[window brand name] window balance replacement" You might find a video tutorial specific to your window type.
