What can excessive moisture intrusion lead to in a building?

Excessive moisture intrusion in a building is a significant concern for both structural integrity and health. One of the most critical effects of moisture is mold growth; when moisture levels are high, it creates an ideal environment for mold spores to germinate and proliferate. Mold not only poses health risks to occupants, such as allergies and respiratory issues, but it can also lead to substantial damage to building materials, as it can eat away at wood and drywall.

Additionally, moisture can cause structural deterioration. Wood can warp, rot, and weaken, while metals may corrode. Over time, the accumulation of moisture can lead to costly repairs and renovations to maintain the safety and soundness of the structure. In severe cases, it may even compromise the building's overall stability.

While improved energy efficiency, enhanced indoor air quality, and reduced pest activity are important aspects of building maintenance and environmental health, they can be negatively impacted by excessive moisture. For example, damp conditions can actually attract pests rather than deter them. Thus, managing moisture levels is essential for maintaining a healthy, safe, and structurally sound environment.
