Moisture. If the fog is between the window panes, this is likely due to failed seals. Modern windows are made of two or more panes of glass and filled with gas (e.g. argon). When the seals fail, this gas escapes and is replaced by moist air which eventually clouds the window (and reduces the insulating properties of the unit).

If the fog is on the inside or outside surface of the glass, you likely have a humidity issue related to temperature and ventilation.

Air leakage can come from any number of sources. One possible source is your windows and doors. Cheap units, old units, or poor installs can all contribute to air penetration through and around your windows.

Moisture.

This can be caused by actual water infiltration, but more often is due to condensation buildup. Condensation occurs when the glass becomes cold enough that moisture-bearing air coming into contact with the pane cools enough to lose its moisture-bearing capacity, just like when a cold drink causes your cup to become moist on the outside.

If it’s 40 degrees below zero when this happens, just dry the windows off. If this is happening at normal temperatures, you may have a ventilation or humidity problem, or your windows are not sufficiently insulated and may have failed seals or other issues.

This can indicate failing or clogged “weep holes” - little holes designed to drain water that lands on the outside of the window.

Some possible culprits:

• Poor installation (caulk and trim issues)

• Improper flashing (more common than it should be!)

• Aging/cracking window frames

• Failed window seals

• Aging or breaking units and hardware

• Structural movement (settling or sagging)

• Warping (expansion and contraction)

• Dirty or rusted mechanisms
