Dampness refers to the presence of moisture in the air or on surfaces, which can lead to various issues in buildings and environments. It often occurs in areas with poor ventilation, high humidity, or water leaks. Excessive dampness can promote the growth of mold and mildew, which can affect indoor air quality and cause health problems. In addition to health concerns, dampness can damage structures and materials. It can weaken walls, cause paint to peel, and lead to wood rot. Addressing dampness typically involves improving ventilation, repairing leaks, and using dehumidifiers to maintain a balanced moisture level in the environment.
