Managing Condensation in Apartments

Condensation is a common issue in apartments, particularly during the colder months. Understanding its causes and how to manage it is crucial for maintaining a healthy living environment. Here’s a comprehensive guide based on the insights from Red Dog Property Inspections.

What is Condensation?

Condensation occurs when the air in an apartment reaches a level of humidity where the dew point is above the temperature of a surface on which condensation is forming. This often results in water droplets on windows, walls, and other surfaces.

Causes of Condensation

Several factors contribute to condensation in apartments:

  1. Environmental Conditions: External ambient temperature, humidity, and solar/radiant loads can cause the façade glazing and framing system to cool, leading to condensation. This is especially common in Melbourne between May and August​ (Apartment Condensation)​.
  2. Internal Operations: Activities within the apartment, such as cooking, showering, and drying clothes, can elevate humidity levels, contributing to condensation.

Tips to Minimize Humidity and Prevent Condensation

  1. Use Exhaust Systems: Make sure to use exhaust fans in bathrooms and over cooktops. Allow them to run for a period after use to exhaust moisture effectively​(Apartment Condensation)​.
  2. Cooking Practices: Use lids on cooking equipment and boil water near the range hood to reduce the amount of moisture released into the air.
  3. Ventilation: Ventilating the apartment by opening windows or balcony doors slightly can help reduce moisture levels. Even a small opening can make a significant difference.
  4. Air Conditioning: Use air conditioning units in cooling mode to dehumidify the apartment. This is particularly effective in reducing indoor humidity levels​(Apartment Condensation)​.
  5. Dehumidification Equipment: In extreme cases, consider using dehumidification equipment. These systems are commercially available and are commonly used in humid environments.
  6. Distinguishing Between Window Leaks and Condensation

It’s important to differentiate between window leaks and condensation. Window leaks usually involve water penetration from outside, whereas condensation results from indoor humidity. Understanding this distinction can help in addressing the root cause of moisture problems effectively.


By following these practices, you can significantly reduce the humidity levels in your apartment and prevent condensation. Regular maintenance and mindful living habits are key to ensuring a comfortable and healthy living environment.
