Noticed moisture or a foggy appearance between your window panes? If the glass looks cloudy and the condensation can't be wiped away from either side — that’s a clear sign your window has lost its seal.

In everyday language, this is called a foggy window, and it means that moisture has penetrated inside the sealed glass unit due to a broken seal.

Why You Shouldn’t Ignore the Problem

  • Reduced insulation — moisture lowers thermal performance
  • Poor visibility — foggy glass blocks the view and looks unattractive
  • Risk of mold — trapped moisture creates a perfect environment for mold
  • Decreased property value — damaged windows make your home less appealing for buyers

Foggy Window Repair: What Are Your Options?

You don’t always need to replace the entire window unit. There are several cost-effective solutions:

Seal Repair and Glass Regeneration

  • Moisture is extracted from between the panes
  • Ventilation valves or micro-openings are added
  • The unit is treated with a drying agent and resealed


Suitable if the damage is minimal and the frame is in good condition.

Glass Unit Replacement (Without Replacing the Frame)

  • The most common and effective solution
  • Only the sealed glass unit is replaced, not the full window
  • A new energy-efficient double or triple-pane unit is installed with a warranty

Ideal for older windows where the seal has worn out over time.

Full Window Replacement

  • Required only in extreme cases:
    • Frame is damaged or warped
    • Structural issues
    • Window is over 15 years old

Signs You Need a Repair

  • Condensation appears inside the sealed unit, not on the surface
  • The area near the window feels colder than the rest of the room
  • Foggy or wet spots are spreading over time
  • Frame or sash shows discoloration or mold
