A double-hung window that keeps sliding down is often due to a misaligned balance shoe. Follow these six simple steps to get your window working properly again.
Time Required
5 minutes
Cost
$0 (assuming you have a flathead screwdriver)
Step-by-Step Guide
1. Find the Balance Shoe
- Each glass section of the window is called a sash.
- The balance shoe, part of the pulley system holding the sash in place, is often at the bottom of the window frame due to forced closures.
- Locate it in the side tracks of the window frame.
2. Locate the Tilt Pin
- Each sash has a tilt pin, a small U-shaped metal piece, sitting in the balance shoe.
- These pins allow the sashes to tilt outward for easy cleaning.
3. Unlock the Balance Shoe
- Insert a flathead screwdriver into the tilt pin.
- Turn the screwdriver 45 degrees to the left to unlock it (the U-shape will resemble a "C").
4. Reset the Balance Shoe
- Move the balance shoe 2 inches from the bottom of the sash.
- Relock the tilt pin by turning it back to the U-shape with the screwdriver.
5. Adjust the Lower Sash
- Tilt the lower sash outward by removing the tilt latches at the top.
- Align the bottom of the sash with the repositioned balance shoe.
- Gently tap the sides of the sash until you hear a small pop, indicating the tilt pin has reengaged with the balance shoe.
6. Reset the Window and Test
- Snap the lower sash back into place.
- Ensure the tilt latches are securely hooked into the frame.
- Move the window up and down to confirm it stays in place.
Troubleshooting Tips
- Repeat the Steps: If the sash still slides, double-check the pin’s position and ensure it locks into place.
- Check the Upper Sash: Misalignment of the upper sash may also cause issues. Repeat the process on this sash if necessary.
- Replace the Balance Shoe: If damaged, balance shoes can be purchased for $5–$10 at hardware stores.
When to Call a Pro
- If DIY steps don’t solve the issue, consider hiring a local window repair specialist.
- Repair cost: ~$100
- Window replacement: Starts at ~$200
- A professional can also address cracks, chips, or locking problems that could compromise security or energy efficiency.
With just a few tools and a little patience, you can fix your double-hung window and enjoy smooth, secure operation!
