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.
