consortium now believes that many more US homes particularly in
Florida, Southeast Texas, Alabama, Mississippi and Louisiana have
toxic Chinese drywall than previous calculations. Many homes in
the US have toxic Chinese drywall INTERMIXED with US made drywall.
If these homes were built or remodeled after 2001, we believe a
small amount of imported Chinese drywall is enough to make an entire
house toxic. The Gulf Coast is also of concern due to storm damaged
homes which have been rebuilt during this same time period. The
net result is instead of ending up with tens of thousands of now
toxic US Southeast homes, we are convinced we have 100,000's of
toxic US homes."
Toxic Chinese Drywall A National Problem?
there is a problem with discovering US States-outside of the extreme
US Southeast with toxic Chinese drywall. "We now think that
the reason we have found so much toxic Chinese drywall in the US
South, or Southeast is high heat, combined with high humidity."
The group believes the high heat-high humidity combination may be
the cause of the imported Chinese drywall-off gassing, which causes
AC coil failures, creating metal deterioration, copper that turns
black, electrical issues in the homes, combined with upper respiratory
issues, nose bleeds, headaches for most homeowners, or their family
members. Because the US Northeast, Mid West & or the Western
half of the US do not have high thresholds of humidity; severe metal
deterioration may not occur in homes with Chinese drywall, but the
homeowners may still be sick. The group is trying to determine the
best ways to discover toxic Chinese drywall in the US Northeast,
Mid Atlantic, Mid West, and West. As this information is determined,
the Chinese Drywall Complaint Center will update its web site immediately.
Chinese Drywall Time Frames
Southeast Homes built or remodeled between 2001 & 2008 may have
this potentially toxic Chinese drywall in the house, or condominium.
According to the Chinese Drywall Complaint Center, "if your
home or condominium was built or remodeled after 2001, you have
experienced numerous air condition coil failures, your copper electrical
ground wires have turned black, and you are suffering from upper
respiratory issues, nose bleeds, unexplained rashes, or severe allergy
type symptoms, your house may contain toxic imported Chinese Drywall,
or tainted us drywall. If this is the case, please call the Chinese
Drywall Complaint Center at 866-714-6466
Update: Recent positive findings for Chinese Drywall, were made
in a Houston area home built in 2009.
Urgent Alert: Time
is of the essence in identifying as many homeowners as possible,
with a specific type of toxic Chinese drywall called Knauf Tianjin-because
we could be on the verge of a one time only universal settlement
from the manufacturer of Knauf Tianjin Chinese drywall.
did it come from?
what is Chinese Drywall and where did it come from? The term "Chinese
Drywall" (or tainted drywall or wallboard) refers to drywall
imported from China from 2001 to 2007 which contains contaminants
that are emitting gases which usually (but not always) create a
noxious odor and corrode copper and other metal surfaces, thereby
damaging your air conditioner, electrical wiring, copper plumbing,
appliances and electronics.
are the peak years for toxic Chinese drywall being used in new or
remodeled homes in Houston, Dallas, Austin and
other cities in Texas?
to the Chinese Drywall Complaint Center, "as far as new homes
in Texas, we think toxic Chinese drywall was first introduced in
2003, or 2004. The peak years wee 2005-2007." The group adds,
"We are also very nervous about Texas homes damaged by Hurricanes
Rita, Ike, or Gustav. If New Orleans is any guide; many of the homes
in Texas repaired because of storm damage, may have involved toxic
Chinese drywall. "
indication that a home might have the toxic drywall could be having
continuous failures of air conditioning coils, might have copper
wiring in the electrical receptacles that have turned black, oven
or stove elements, or refrigerator coils may have failed. The Homeowners
Consumer Center has also discovered that computers, TV sets, radios,
DVD players, smoke detectors, microwave information display panels
may have failed in homes, where the toxic Chinese drywall is present.
or the Health Concerns
have been no formal health studies on the affects of exposure to
toxic Chinese drywall. However, some common denominators appear
to present, as follow: nose bleeds, headaches, coughs, upper respiratory
or sinus issues and rashes.
US States are most likely to have the Toxic Chinese Drywall?
to the Homeowners Consumer center " We think all US States
will have the Chinese drywall. The new states we worry about the
most are Texas, Florida, California, Arizona, Colorado, The Northwest,
Hawaii and Alaska. Florida will easily go over 100,000 new homes,
and we are certain the same will be true of Texas. Remodeled homes
in the US could easily be 200,000+ with the toxic Chinese drywall."

following excerpt is from the CPSC website:
What are the health symptoms and risks?
Answer: The most frequently
reported symptoms are irritated and itchy eyes and skin, difficulty
in breathing, persistent cough, bloody noses, runny noses, recurrent
headaches, sinus infection, and asthma attacks. Since many consumers
report that their symptoms lessen or go away when they are away
from their home, but return upon re-entry, it appears that these
symptoms are short-term and related to something within the home.
staff of the CPSC and CDC agree that the levels of sulfur gases
detected in the affected homes in the fifty-one home study were
at concentrations below the known irritant levels in the available
scientific literature; however, it is possible that the additive
or synergistic effects of these and other compounds in the subject
homes could potentially cause irritant effects to consumers.
Question: What are the electrical or fire safety concerns
and what I should I watch for in my house?
Answer: Consumers have reported
blackened and corroded metal in their homes. Particularly, consumers
have reported failures of certain components such as: (1) premature
failures of central air conditioning evaporator coils located indoors
as part of the central air conditioning unit air handler; and (2)
intermittent operation or failure of appliances, such as refrigerators
and dishwashers, and electronic devices such as televisions and
video game systems.
see the FAQ below if you have questions about gas service.
You should generally watch for the following potential electrical
hazards in your home:
Power outages - a circuit
breaker which needs resetting frequently without any apparent cause;
especially if a ground-fault circuit interrupter (GFCI) or arc fault
circuit interrupter (AFCI) trips frequently. Arc-fault circuit interrupters
are a special kind of circuit breaker that is designed to detect
arcing conditions in the electrical wiring.
Dim/flickering lights - lights
dim often without any specific cause, such as the air conditioner
or the refrigerator turning on.
Arcs/sparks - bright flashes
or showers of sparks anywhere in your electrical system.
Sizzles/buzzes - unusual sounds
from electrical system devices.
Overheating - parts of your
electrical system, such as switch plates, dimmer switches, receptacle
outlet covers, cords and plugs may be warm as a normal consequence
of their operation but should not be discolored from heat or painful
Odors - pungent smells such
as strong fumes from overheating plastic or electrical insulation
Electrical shocks - any shock,
even a mild tingle. Multiple symptoms would be a stronger indication
What should I do if I suspect the corrosion has affected my gas
Answer: If you suspect corrosion
has affected your gas service, please consult your gas supplier
you suspect a gas leak in or outside your home:
LEAVE the area
IMMEDIATELY and tell others to leave too.
DO NOT turn
any lights on or off, smoke, or operate any vehicle or equipment
that could cause sparks.
DO NOT attempt
to turn gas valves on or off.
call your gas supplier from a neighbor's phone. Follow the gas supplier's
If you cannot
reach your gas supplier, call the fire department.
and service must be performed by a qualified installer, service
agency or the gas supplier.

of Tainted or Chinese Drywall
the material source of the problem is known, a complete understanding
of the cause of the problem remains unknown (i.e., we do not know
what materials in the Chinese drywall are triggering the release
of sulfur gases).
the most common theory was that the drywall was manufactured in
gypsum mines in China which used fly ash, a waste material that
is a byproduct from power plants using coal. Samples of Chinese
drywall tested by United Engineering, however, consisted of 5-15%
organic material, which contradicts the theory that Chinese drywall
was made of waste from coal fired power plants. Some now believe
that the tainted drywall from China comes from mined gypsum, not
synthetic gypsum which is made from coal ash. Mined gypsum contains
high levels of strontium, which is visible as inclusions in electron
theory is that Chinese drywall contains bacteria (possibly from
the water source used to manufacturer the drywall) which is degrading
iron and sulfur compounds to produce sulfur odors, although the
CPSC's recent report disputes this theory.
of the problem is due to China's failure to cooperate. Indeed, to
date, Chinese manufacturers have yet to disclose the chemicals put
into their drywall or the manufacturing processes. See China Plays
