    "When Lori and Nate Lee moved from Maryland to Lewis Center
    five years ago, they bought the perfect home for their
    growing family: 2,800 square feet, four bedrooms and a
    basement they immediately finished....


    ...Every home will build up mildew and mold in moist areas
    such as bathrooms. Much of it is harmless if regularly
    cleaned. But some types of mold, such as stachybotrys, can
    be serious, especially to children and those with allergies
    or respiratory problems such as asthma...
    ...The clearest evidence of mold is seeing it. Other clues
    that your home might have a hidden mold problem include:

    Moisture routinely appears on inside walls or windows.

    Dark water streaks appear on the outside walls of the
    home, suggesting black mold behind the wall.

    Screws, electrical receptacles or other metal pieces in
    the wall are rusty.

    The home has a musty smell.

    Floors under carpet along exterior walls are damp.

    The home's residents have coughs, watery eyes or sore
    throats they can't shake.

    Steps to take

    Monitor indoor humidity with a hygrometer. Readings
    should be below 50 percent in the summer and below 35
    percent in the winter.

    Place a dehumidifier in damp areas such as basements.

    Open windows or use exhaust fans when producing moisture
    in the bathroom or kitchen.

    Remove carpet in damp areas such as basements.

    Contact a mold inspector or other specialist if mold is
    visible on drywall, wood floors or other organic surfaces.
    Such inspectors aren't licensed, so consumers should check
    their credentials and ask how long they've been in business
    and how they've been trained and certified.

    Contact a lawyer if you think you have a legal case
    against the builder, but expect to spend in the five
    figures if you sue....

    .."I kept cutting and cutting and cutting," said Reichman,
    who has spent the past month repairing the damage....

    ...For Reichman, the discovery was all too familiar. He and
    other builders and experts say mold plagues some newer
    central Ohio homes, especially those built during the
    housing boom of 1999 to 2006.

    "I'm seeing this over and over," Reichman said. "The time
    frame when those homes were built, in that period, five to
    seven years, will have those issues."...

    ..."I've seen it from several builders," Reichman
    said. "It's sad to say that homes built 100 years ago are
    holding up better, which is upsetting because we have so
    much better technology and materials today if we used them."

    Others agree that mold has become a familiar problem in new
    homes, especially those with stucco siding.

    "There were not problems like this 35 or 40 years ago,"
    said Jerry Warner, the city of Delaware's chief building
    inspector who helped a Delaware couple negotiate a mold
    problem with Dominion Homes.

    ...."If I built a house 80 or 100 years ago, I was a true
    craftsman," said Stubbs, who lived in central Ohio before
    becoming director of facilities planning and construction
    for Clarke County Schools in Georgia. "I'd build one house
    a year. ... We don't build like that today. We take
    shortcuts."

    Other explanations for the rise of mold problems in newer
    homes include:

    Oriented strand board, which became a common sheathing
    material for homes about 20 years ago, absorbs and
    transfers water more readily than plywood, which was the
    sheathing of choice for older homes. Even when plywood is
    used today, it is more likely to be three-ply plywood
    instead of the four- or five-ply used in earlier homes.

    Stucco is thinner than it used to be, with less cement,
    and is frequently poorly installed, with two thin coats
    instead of three thick ones.

    Many homes built during the housing boom used a paper
    vapor barrier, which can be difficult to properly install,
    instead of Tyvek or other wraps commonly used in the past
    few years.

    Newer homes are typically built in empty fields, offering
    no protection from wind, rain and sun - especially a
    problem on western exposures.

    Homes built in the past 20 years tend to be tighter than
    older homes and therefore more likely to trap moisture
    inside if not properly ventilated, creating what Tom Flood,
    the president of Air Technology in Hilliard, calls a "giant
    petri dish." This was especially a problem in the 1980s
    and '90s, when builders commonly put plastic between the
    studs and drywall as a moisture barrier.

    ....During the housing boom, homes didn't receive the
    attention from swamped inspectors that they might have
    otherwise."....
