Understanding How Mold Spreads in a House

Mold can spread in a house through a variety of ways, including:

  1. Airborne spores: Mold reproduces through tiny spores that float through the air. These spores can land on damp surfaces and begin to grow.

  2. Water leaks: Leaks in pipes, roofs, or walls can create damp conditions that mold thrives in.

  3. High humidity: Humidity levels above 60% can create an environment where mold can grow.

  4. Flooding: Flooding can introduce large amounts of water into a house, creating ideal conditions for mold growth.

  5. HVAC systems: Mold can grow in HVAC systems and be distributed throughout a building through the air ducts.

Once mold begins to grow, it can spread quickly if left untreated. It can grow on many different types of surfaces and can quickly colonize large areas. It can also cause structural damage to the house. It is important to address any potential mold issues as soon as possible, by identifying and fixing the source of moisture and cleaning up any visible mold growth.

It is also important to maintain good ventilation in the house to prevent mold from growing.
