What causes mold to develop?
Mold needs these conditions before it can begin to grow inside a building:
- Mold spores
- A food source (e.g. wood, drywall, cotton)
- Darkness (mold can’t grow under ultraviolet light)
- Warmth (mold can’t grow in freezing temperatures)
- Moisture (e.g. water leaks, humidity, condensation)
Accordingly, moisture is really the key cause of mold growth since the other conditions on the list are always going to be present in homes.
