Mold in your home

moldy houseEnvironmental issues in the home are a concern.  Although there are linked health concerns, mold is an environmental issue that is often misunderstood because it can be found almost everywhere and its indoor growth may be managed.

Mold is a fungus; and because there are thousands of types of molds (the exact number is unknown), it is often referred to in the plural.  Molds are essentially found everywhere.  Molds typically grow outdoors in moist areas and live in soil, on plants, wood, and decaying plant matter; however, mold can also grow indoors if the humidity is high enough, or if there is an unrepaired water leak.  Molds are useful in digesting dead plant matter as well as for other purposes; however, exposure to molds can also be a health risk.

Molds reproduce via spores; mold spores are found outdoors and indoors surfaces, and can remain dormant for years before they grow.  Mold spores enter the home through doorways, windows, and outdoor vents; as well as hitching a ride into the home by attaching themselves on clothing, pets, and other items that are carried into the home.  If the spores land on a damp surface (such as where leaks or flooding may occur in the home) they begin to grow and digest the material.  Wet building materials can offer a perfect meal for molds.  Molds can thrive on materials made from paper products, cardboard, ceiling tiles, and wood products; however, molds can also grow on many other materials, such as dust, paint, insulation, drywall, carpet, and fabric.

The most common indoor molds are Cladosporium, Penicillium, Aspergillus, and Alternaria.  Mold problems in the home can usually be seen and/or smelled.  If unimpeded, molds can, over time, eventually destroy the materials where they grow.  For this reason, prevention and/or elimination of mold growth in the home can prevent damage to your home and possessions, as well as save you money.

Although controlling humidity levels and properly ventilating the home may inhibit mold growth in the home, a problem can still exist.  To determine and/or repair a mold issue, a certified mold inspector and/or licensed mold remediation professional should be consulted.

Many people are sensitive to molds and sever reactions may occur; the Institute of Medicine linked indoor mold exposure to upper respiratory symptoms.  However, according to the Centers for Disease Control (, the presence of mold isn’t always an indoor health issue.  Obviously, a physician should be consulted immediately when symptoms from mold exposure are experienced.
