Key takeaways
- Drafts and condensation are the clearest signs
- Failed seals and rot usually mean replacement
- A single broken part can often be repaired
Comfort signs
Drafts near the glass, cold spots in winter, hot spots in summer and condensation on the inside of the glass all point to a window that is not doing its job.
Noise that seems to come straight through the glass is another sign, especially if the windows are single-pane.
Physical signs
Windows that are hard to open, will not stay up or will not lock may only need hardware. Fog between double panes means the seal has failed. Soft or crumbling wood at the sill means water has gotten in.
Cracked glass and warped frames are more serious.
What to do next
Check each window and note what you see. If one or two windows have simple problems, repair may be enough. If many windows share the same problems, replacement is likely the better value.

Quick answers
How old are windows when they need replacing?
It depends on the material and the weather they face. Many windows last decades, but seals and hardware often fail first.
Will new windows lower my energy bills?
They can help, especially over old single-pane windows, but savings depend on your house and climate.
