Drywall made in China is typically stamped with the word China or with the name of the manufacturer on back. Tianjin Knauf is the most common manufacturer stamp on the back of such drywall in our experience.
New Home Buyers Beware of Chinese Drywall
Practically everyone in south Florida from the Florida Keys to Hobe Sound has heard that Chinese drywall when used in the construction of your home, could cause a multitude of problems from electrical wiring corrosion and tarnished jewelry and silverware, to health anomalies like respiratory illness, asthma, coughing, difficulty breathing, headaches and sinus issues. If you are in the process of buying a home, it is critical that you first make sure that it is 100% free of Chinese drywall.
Because of the high temperatures and humidity in South Florida, detecting Chinese drywall in your home is easy. Chinese drywall emits the sulfurous gases carbon disulfide, carbonyl sulfide, and hydrogen sulfide. As temperatures rise, these gases cause your home to smell like rotten eggs.
Copper pipes, copper wiring and copper air conditioning coils are all effected by the chemical emissions of Chinese drywall and you can tell when the copper color of theses surfaces turn black. Normal copper pipes will turn an aqua green-blue when corrosion builds up.
Copper pipe turned black due to Chinese drywall induced corrosion.
The construction boom of 2001 – 2005 plus the damage caused by no less than nine hurricanes in 2004-2005 caused a dry wall shortage that was met by builders importing approximately 500 million pounds of inexpensive Chinese drywall. It is estimated that this amount of drywall is enough to build 60,000 home and that is how many south florida and gulf coast homes could be effected. All of Florida is effected by the hazards of Chinese drywall.
If you think Chinese drywall emissions are not an acute health hazard that can effect your family you’re wrong. “Even quick exposures of an hour or two can cause sore throats, eye irritation, coughing, shortness of breath, chest pain, and nausea. Long term exposure, over a period of weeks, is believed to cause chronic fatigue, insomnia, loss of appetite, dizziness, irritability, headaches, and memory loss.” (source www.wikipedia.com)
In addition to the adverse health effects of Chinese drywall, removing it from your home and replacing copper pipes, copper electrical wiring, and copper air conditioning coils is almost prohibitively expensive. On a home costing $250,000, replacing the drywall and the copper alone can cost over $100,000. Don’t count on your home inspector either to tell you that you have a Chinese Drywall problem, as this is the last thing that they would think to check. It is up to you the prospective South Florida homebuyer to hire a professional, independent Chinese drywall inspector to determine whether or not the home you may be about to fall in love one could be a terrible investment.
