A window that won’t stay open—or suddenly slams shut—is more than just a nuisance. A dropping window can compromise your home’s safety, efficiency, and comfort. If you’re dealing with this issue, you’re not alone. Many homeowners in Will County face this common problem, especially in older homes.
In this article, we’ll explain why your window is dropping, how you can fix it, and when it might be better to repair or replace it entirely.
Why Is My Window Dropping?
A dropping window usually points to a mechanical failure in the window’s balance system—the components that hold the sash in place. The most common causes include:
- Broken or worn-out sash cords (common in older wood windows)
- Failed window balance springs (found in many modern double-hung windows)
- Track or frame misalignment
- Improper installation
Over time, regular use, moisture, and temperature fluctuations can wear these components out.
Step-by-Step: How to Fix a Dropping Window
Before beginning any repairs, make sure you know what type of window you’re working with: wood, vinyl, or aluminium and whether it uses sash weights, spiral balances, or block-and-tackle systems.
1. Inspect the Window Track and Frame
Dirt, warping, or frame damage can interfere with the sash movement. Clean out debris and look for visible damage.
2. Identify the Balance System
Modern windows use spring-loaded balances inside the frame. Older models may use sash cords connected to counterweights hidden in the frame.
3. Replace Broken Window Balances or Sash Cords
If the balance or cord is damaged, it will need replacement:
- For spiral balances, use a balance tensioning tool to wind and secure it.
- For sash cords, remove the window trim, replace the cord, and reattach the counterweight.
4. Test the Sash for Smooth Operation
Once the repair is done, slide the window up and down. It should stay in place when opened and move smoothly.
When Should You Call a Professional?
If your window drops after basic repairs—or if you’re unsure about the type of balance system—it’s best to consult a window repair expert. DIY fixes can sometimes lead to further damage, especially with older or speciality windows.
