Why is moisture intrusion a critical focus during inspections of windows and doors?

Moisture intrusion is a significant concern during inspections of windows and doors because it has the potential to compromise the structural integrity of building materials. When moisture penetrates these areas, it can lead to deterioration of wood, corrosion of metal components, and weakening of insulation materials. Furthermore, excessive moisture creates an environment conducive to mold growth, which poses health risks and can lead to costly remediation efforts.

While aesthetic issues can arise from moisture intrusion and it can impact the resale market, these are secondary to the primary concern regarding the health and safety implications. Similarly, while poor ventilation may induce moisture problems, the main focus during such inspections is understanding how water can damage the structure and foster mold, making this answer particularly relevant to the critical elements of building inspections. Preventing moisture intrusion is essential for maintaining a healthy, safe, and structurally sound environment.
