Addressing humidity problems in window openings is a vital aspect of building management. Windows, by their very nature, are designed to provide a blockage between the external environment and the indoor space while allowing ventilation to enter. However, when not properly cared for, they can become a source of moisture-related problems.

Moisture ingress in window openings can occur due to various reasons such as:

• Defective window installation or flashing around the frame
  
• Faded or distressed weatherstripping
  
• Cracked or defective window glazing
  
• Dew forming on the cooler window glass or frame
  
• Inferior exterior wall fabrication or covering
  
  

To address moisture ingress in window openings, building owners and managers can take multiple steps:

1 Identify and correct the origin of the problem: This may involve inspecting the window frame and surrounding area for signs of structural weakness, checking for air leaks, and verifying that the capping around the window is properly settled and functioning.

2 Inspect and replace weatherstripping: Over time, weatherstripping can become tattered, allowing moisture to seep into the window opening. Replacing it with new material, such as rubber, can help to prevent ongoing water intrusion.

3 Repair or replace damaged glass or glazing: Damaged or defective glass can not only allow water to enter but also compromise the stability of the window. In some cases, it may be possible to repair the shattered glass pane, but in others, replacing it may be the best alternative.

4 Improve ventilation and air circulation: One of the main causes of moisture-related problems in windows is condensation forming on the window glass or frame. By improving ventilation and air circulation around the window, you can
