Chinese Drywall


About Chinese Drywall

Drywall is a dried layer of gypsum plaster pressed between thick layers of paper. It is a common building material that has come under intense scrutiny after posing hazardous effects to human health and the environment, particularly by the type being brought into the United States from ChinaSubsequently, Chinese drywall has become a “hot topic” with the media.  After discovery of gas emissions that may irritate the respiratory system and skin, causing sinus problems and nosebleeds, this controversial material has triggered serious concerns in many American neighborhoods. Laboratory tests of the material show alarming levels of sulfurous gas emissions including carbon disulfide, carbonyl sulfide, and hydrogen sulfide. These gasses produce a foul odor of rotten eggs that becomes worse at warmer temperatures and high humidity, a weather condition naturally common in Florida and nearby states. Chinese drywall reacts chemically with metals such as copper, resulting in corrosion to electrical wiring, air conditioner coils, pipes, plumbing and other home equipment.  Chinese drywall, also known as contaminated drywall/tainted drywall, is made from mined gypsum, which speculatively contains bacteria that breaks down iron and sulfur compounds resulting in sulfurous gas compounds.

Health Hazards

Due to its toxic content, the controversy surrounding this subject is growing at an alarming rate.  The Consumer Product Safety Commission has received a great number of complaints from households throughout the U.S.  As a result of the climate, the Florida Department of Health has been inundated with questions regarding the use of Chinese drywall. Most of these are health-related issues, citing symptoms such as recurring headaches, irritated and itchy eyes, dizziness, sore throat, breathing difficulties, dry cough, runny nose, nosebleeds and sinusitis, among others.One hazardous compound thought to be found in Chinese drywall is strontium sulfide.  Strontium sulfide is a substance that may adversely affect bone growth, visual and sensory perceptions and could pose serious problems to the cardiovascular system, eyes, kidneys, liver and skin.

How to Spot Chinese Drywall?

Other than the rotten-egg smell it produces, there are additional signs that may indicate a problem involving Chinese drywall. Copper, silver and iron will corrode in the presence of hydrogen sulfide and other emissions causing black spots or rusts coating these metals.

Hiring a Professional Inspection Service

Inspection Connection will look for signs of possible Chinese drywall usage.  These include a sulfur (rotten egg) odor, markings on the drywall visible in the attic, and discoloration of the electrical wiring and the A/C coils.  If a sample from a wall is removed and sent to a lab to be analyzed, and are very costly.  This sample would be only one sheet of drywall out of the hundreds in the house, so it would not be very effective.  We recommend this option only if we smell sulfur or find evidence from the visual inspections. Inspection Connection personnel are experts in home inspections.  We also perform warranty inspections, 4 point insurance inspections, specialty inspections, and of course buyer and seller inspections.  For information, please contact Jesse Farmer at (904) 384-3018.
