Introduction
Old or faulty windows can lead to energy loss, safety issues, and home discomfort. How do you know when it’s time to replace them? Let’s look at the top 10 signs:

1. Drafts or Cold Spots
If you feel a breeze near closed windows, your seals have likely failed.
2. Rising Energy Bills
Leaky windows force your HVAC to work harder, increasing costs.
3. Condensation Between Panes
Moisture inside the glass usually means seal failure.
4. Difficult to Open or Close
Warped frames or broken mechanisms can cause this issue.
5. Outside Noise
If your home isn’t quiet, poor insulation might be to blame.
6. Cracked or Broken Glass
Obvious safety hazard—should be replaced immediately.
7. Rotted or Warped Frames
Wooden window frames deteriorate over time when exposed to moisture.
8. Faded Interiors
Old windows may not block harmful UV rays that damage furniture and floors.
9. Poor Curb Appeal
Foggy, cracked, or mismatched windows lower your home’s appearance.
10. Age Over 20 Years
If your windows are more than two decades old, they’re likely inefficient.
Why It Matters in Chicago
