Condensation between panes
Moisture trapped inside a sealed double-pane unit is different from condensation you can wipe off the room-side surface.

Signs of a failed seal
Why Double-Pane Windows Become Cloudy or Foggy
Double-pane windows commonly use an insulated glass unit (IGU): two panes joined by a sealed spacer system. When the perimeter seal fails, moisture can enter the space between the panes, creating haze, streaking or condensation that ordinary cleaning cannot remove. Not every foggy-looking window has a failed seal, so identifying where the moisture sits is the first step.
Hazy or cloudy window glass
A persistent milky appearance or streaking between panes may indicate deterioration of the insulated glass unit's edge seal.
Failed insulated glass seals
Insulated glass units (IGUs) contain multiple panes sealed around the edges. When the seal fails, moisture can enter the space between them.
Replacement sealed glass units
When the existing frame and sash are suitable, a properly specified replacement IGU may restore visibility without replacing the whole window.
Understand the difference
Condensation on the Glass vs. Moisture Between Panes
Condensation on the interior surface may form when warm, humid indoor air meets cool glass. It can usually be wiped away and does not, by itself, prove the insulated glass seal has failed.
Condensation between panes sits inside the sealed glass unit. If it remains after both exposed surfaces are cleaned, a failed IGU seal may be responsible. Replacing the sealed unit is often a more durable solution than surface cleaning or temporary defogging.
Quick homeowner checks
- Look closely to see which surface holds the moisture.
- Clean the accessible inside and outside glass surfaces safely.
- Check whether the haze remains visibly between the panes.
- Note any cracked glass, damaged sash or frame issues.
- Take clear photos to share when requesting an estimate.
Replacement options
Can You Replace Foggy Glass Without a New Window?
In many cases, yes. If the existing sash and frame are sound and the glazing system allows it, a new insulated glass unit can replace the failed one. This approach retains the surrounding window assembly. The correct option depends on frame condition, window design, unit dimensions, glass specifications and installation access.
IGU glass-only replacement
A possible option for failed sealed glass when the surrounding window is suitable for reglazing.
Glass specification matters
Thickness, coatings, safety-glazing needs and the existing window design affect the replacement unit.
When broader work is needed
Damaged frames, faulty operation or other defects may require more than glass replacement.
