Drafts and cold spots
If you feel air moving near closed windows — or certain rooms never warm up — seals or fit may have failed. This is especially common on north-facing walls in winter.
Condensation between the panes
Fog or moisture sealed between glass means the insulated unit has failed. It won’t “dry out” on its own; the glass package needs replacement.
Windows that stick, rattle, or won’t lock
Hard-to-open windows are more than an annoyance — they’re a safety and egress issue. Smooth, secure operation is a must for aging in place.
Rising heating or cooling bills
When usage hasn’t changed but bills keep climbing, inefficient windows are a frequent culprit alongside insulation and HVAC.
Age (20+ years)
Builder-grade windows from the 1990s–2000s are often due for an upgrade. Even if they “still work,” newer glass and frames make a bigger comfort difference than most homeowners expect.
FAQ
Can fogged windows be repaired?
