there are no local, state or federal regulations on how to identify or clean up mold, or
even on exposure limits. This lack of information has left us with bouts of
finger-pointing and public outcry, with most of the blame landing on the backs of
insurance companies. But it is not unheard of to see a contracting company's name listed
among the liable parties.

short, the mold issue is growing, well, like a fungus in our industry. With an
unregulated issue such as this, steeped in lack of education, training and standards,
it's easy to see how quickly things can get confusing and out of hand -- and a bit slimy.
following article will give a brief overview of the basic mold facts and report on the
issue as it stands as of early this year, but it is in no way comprehensive. (Do a quick
Internet search on "Mold" and you'll find more sites to click through to keep you busy
for weeks.) However, we will attempt to weed out the facts from the phooey on mold and
its implications to your business.
Meet The Enemy
mold concerns haven't stemmed from its "newness;" fungus has been around since the dawn
of time. (The Bible references the spreading of "the plague," in which the "unclean item
or property must be removed and destroyed.")
to the Center for Disease Control & Prevention, there is always a little mold everywhere
-- indoors and outdoors. Some mold is considered "helpful" mold, such as those found in
medicines and antibiotics; mold is needed in the breakdown and decaying of dead
also very common in buildings and homes, and will grow anywhere there is moisture and
material on which to feed. Mold spores can enter a building through open doorways,
windows, heating and ventilation systems, and even on your clothes.
airborne spores drop on places where there is excessive moisture, such as near leaky
pipes, roofs or where there has been flooding, they will grow and prosper.
common indoor molds are Cladosporium, Penicillium, Aspergillus and Alternaria. But the
mold that has coined the phrase "Black Mold," or "Toxic Mold," is Stachybotrys atra.
It is the
new bogeyman of the press. The CDC admits there is no accurate information about how
often Stachybotrys atra (or Stachy) is found in buildings and homes; it is less common
than the others, but it is not rare.
Stachy is a
nasty little fungus -- greenish-black and slimy, sometimes with white edges. It was first
identified and described by a scientist from wallpaper collected in a home in Prague in

gypsum board, ceiling tiles, paper and -- their favorite snack -- drywall.
sake of energy efficiency, homes, commercial buildings and other structures built over
the past 40 years have become increasingly airtight. The buildings simply don't "breathe"
the way older structures do.
Add in the
housing boom of recent years and you've got an increase in structures providing a
relative feast for mold.
To clear up
a few things, toxic molds cannot grow on ceramic tile. A little mildew around the bathtub
or shower probably isn't anything to worry about and is more of a house cleaning issue.
Nor is it found in the fuzzy-green molds on your forgotten tuna sandwich. But wet and
leaky areas shouldn't be allowed to go unattended.
fungus can grow exponentially within 24 to 72 hours of initial water damage. Constant
moisture is required for growth -- for Stachy to survive, materials need to be virtually
saturated. But it is not necessary to determine what type of mold you have. The CDC
recommends all molds be treated the same with respect to potential health risks and

children. And the airways of all people constrict when exposed to certain irritants, like

even without conclusive health-risk evidence.

What To Do?
does all this mean for contractors these days? It means education and training is in
order. Mold growing in homes and buildings, whether the "Black Mold" or other molds,
indicates there is a problem with water or moisture. This is the first problem that needs
to be addressed. This is where the trained professionals of the industry come in.
customers' concerns seriously, but don't create or add to panic -- there is enough real
need for remediation without creating fear through advertising or other communications
to refer clients to appropriate experts, expert documents or informative Web sites. But

is now the first state in America to make new toxic mold health laws. The Toxic Mold

will set the stage, so watch for other states to eventually join in the act.
As more and
more information becomes available to the public, mold claims -- and the need for mold
remediation -- will continue to rise. But the best defense is always a good offense.
Fixing clients' water leaks and moisture troubles is a great start to curb the
possibility of toxic mold.
The Road To Mold Certification

the realm of indoor air quality -- and upon closer inspection of his own home -- he

information to industry professionals, and produce highly qualified people in the field
of mold remediation with his company Certified Mold Inspectors & Contractors Institute.

Hurricane, Utah, has certified nine companies in two months of operation. "Cleaning mold
is a temporary solution. It'll re-grow unless you remove it completely and take care of
the water and moisture problems.
because you don't see mold, doesn't mean it's not there, Fry warns. Hidden mold -- behind
walls, wallpaper and ceilings -- has been the cause of several outbreaks of Stachybotrys

mold detection and testing methods to construction and plumbing businesses, and trains
them to locate hidden mold. Day Two covers the remediation portion of certification, and

"Certification is not legally required," says Fry about the lack of regulation on the
mold issue as of yet. But he says completed courses in mold remediation lets clients know
