Mold In Your Home

Most Homes Have a Mold Problem. Even if your home looks clean, chances are good you've got mold, often at levels high enough to trigger allergy and asthma attacks. That bit of dour news comes courtesy of a new university research study that also found the mold is frequently in areas most people don't associate with it -- windowsills, for instance. After surveying 160 homes in seven U.S. cities, Kelly A. Reynolds of the University of Arizona, Tucson, found that 100 percent of the homes tested positive for mold on some inside surface. The discovered molds were all highly allergenic molds. Read the entire home mold research. "Up to one-third of [non-residential] buildings in industrialized countries are sick," according to the World Health Organization, 1995.    The Ottawa, Canada-based Canadian Mortgage and Housing Corporation (CMHC) warns in a pamphlet published at its web site that "if you live in a damp house, or have ever experienced flooding, your house may be breeding an often invisible and always unwelcome intruder - mold." Ken Ruest, Senior Researcher with the CMHC points out that, "a lot of people are unaware there's a toxic mold problem until their house is so badly affected they can't live in it anymore."

Mold fungi grows well in homes, condominiums, apartments, offices, and other work places and buildings because most property owners and managers do NOT properly maintain building roofs; exterior siding; windows; heating, ventilating, and air conditioning [HVAC] equipment and ducts; and plumbing fixtures, water lines, and sewer lines to prevent water intrusion, and/ or they fail to quickly find, detect, search for, and repair mold water plumbing problems such as water leaks, water and sewer breaks, broken water and sewer lines, dripping water, running water, flooding, flood damage, and other water, moisture, humidity, sewer, mold damage problems, black mold infestation, and toxic mold contamination. One square foot of moldy drywall can harbor more than 300 million mold spores.

The food source for fungal growth in buildings may include cellulose, which can be found in ceiling tile, insulation, sheetrock, as well as wood and dirt. Clothing, carpeting and padding, draperies, upholstered and wood furniture, leather shoes, and other cellulose-based home contents are also favorites for mold to eat and grow. Mold organisms have three modes: (1) active, live mold growth when the mold has your house to eat and access to high humidity or water leaks; (2) dormant mold or inactive mold, when the mold spores and mold colonies go into sleep waiting for renewed access to high humidity or water leaks; and  (3) dead mold [no longer capable of reproducing or living]. All three modes are dangerous to health. Even the smell of dead mold can make mold-sensitive persons sick.
