What can lead to mold growth in a home?

Mold growth in a home is primarily driven by a combination of excess moisture and inadequate ventilation. Mold thrives in damp environments, so when there is an accumulation of moisture from sources like leaks, flooding, or humidity, coupled with poor airflow that prevents the moisture from evaporating, conditions become ideal for mold to flourish.

While low humidity levels, high levels of natural light, and proper insulation can help prevent mold growth, they do not directly contribute to mold development. Low humidity reduces moisture, which is a critical factor for mold proliferation. Similarly, high natural light can inhibit mold growth since many types of mold prefer dark, damp conditions. Proper insulation can help in maintaining the desired temperature and reducing condensation, but it is the combination of excess moisture and poor ventilation that creates the perfect breeding ground for mold.
