What can happen if a clothes dryer duct terminates inside an enclosed space?

When a clothes dryer duct terminates inside an enclosed space, it can lead to the accumulation of excessive moisture in that area. Clothes dryers expel hot, moist air during operation, which is a byproduct of the drying process. If this moist air is released into an enclosed space rather than vented outside, it can cause several problems.

The increase in humidity can promote mold growth, which not only damages structural materials like wood and drywall but can also affect indoor air quality and health. Moisture can also lead to deterioration of insulation, create a breeding ground for pests, and cause paint to peel and wallpaper to bubble. Therefore, allowing dryer exhaust to terminate in an enclosed space is not safe and can lead to significant damage over time. This is why proper venting that directs moist air outside is crucial for maintaining both the integrity of the home and the safety of its occupants.
