What is it? Molds are simple, microscopic organisms, found virtually everywhere, indoor and outdoors.  Molds can be found on plants, foods, dry leaves, and other living material.  Mold spores are very tiny and lightweight, and this allows them to travel through the air.  Mold growths can range in many different colors from white, orange, green, brown and black.  When molds are present in large quantities, they can cause allergic symptoms similar to those caused by plant pollen.

What does mold need to grow? Food source such as leaves, wood, newspapers. Intermittent source of moisture.  A place to grow.

Should I be concerned about mold in my home? Yes.  When airborne mold spores are present in large numbers, they can cause allergic reactions, asthma, episodes, infections, and other respiratory problems.  Exposure to high spore levels can cause the development of an allergy to the mold.  When wood goes through periods of wetting then drying, the wood can eventually warp and cause walls to crack or become structurally weak.  Mold can also cause structural damage to your home.

Allergic reactions and/or Symptoms respiratory problems          nasal and sinus congestion dry, hacking cough            wheezing, and difficulty in breathing sore throat                      shortness of breath skin irritation eyes - burning, watery, reddened, blurry vision, light sensitivity constant headache, memory problems, mood changes

Sources of indoor moisture  flooding                    backed-up sewer leaky roof                 humidifiers ice dams                  damp basements plants - watering       constant plumbing leaks

How can I tell if I have mold in my house? If you can see mold or if there is an earthy or musty odor, you can assume that you have a mold problem.  Allergic individuals will have reactions in areas of mold growth.  Look for previous water damage on porous materials.  Visible mold growth often is found underneath materials where water has damaged surfaces or behind walls.  Look for discoloration or leaching from plaster.

Mold Cleanup If the material absorbs water, it is considered porous.  Porous materials should be thrown out or decontaminated if exposed to long periods of dampness.  Material such as hard plastic, glass, and metal can be cleaned and disinfected.  Clean with 1/4 cup bleach (2 oz) mixed in 1 gallon of water.
