Condensation on windows and methods for moisture control

Condensation on windows can lead to serious household issues, including moisture in walls, mold growth, and poor air quality that may affect respiratory health, particularly in children.

To address this, it is essential to identify where the moisture is forming. If condensation appears on the interior of the glass, it indicates that the indoor air is too humid and the home is not venting properly. If moisture is trapped between panes in double glazing, it suggests a failure in the window's seal. Condensation on the exterior of the glass is typically just dew and is generally not a cause for concern.

A primary cause of interior condensation is the buildup of moisture from daily activities like showering, cooking, and drying laundry, combined with weakened air extraction systems. When ventilation units or extraction vents become clogged with dust and grease, they fail to remove excess humidity from the living space.
