Mold can grow on virtually any organic surface that is moist.  In your home, molds can grow on wood, carpet, and insulation affecting air quality by creating allergens and toxic substances. They can also cause asthma attacks.  Limiting excessive moisture in your home will limit mold growth. Having an energy audit of your home or business from Prudent Living can help you discover areas of mold and other problems that can arise from a home losing heat.
