Molds are necessary fungi found everywhere... both indoors and out. They are found in the dust and surfaces of every house. Even houses with ZERO moisture problems!

These tiny microscopic organisms digest organic matter and reproduce by releasing tiny spores into the air. The spores are then transported by humans, pets and air flow.

For molds to grow and reproduce they need two things:

  1. Nutrients.
  2. Moisture.

Growth is stimulated by warm, damp, and humid conditions. Dampness and inadequate ventilation are the biggest factors contributing to excessive mold growth.

Where Do Mildews & Molds Grow?

Mildew and mold can grow on almost any surface; including cardboard, carpets, ceiling tiles, ceramic tiles, fabrics, foods, insulation, plants, sheet rock,
