Chinese Drywall Inspection
Amidst a wave of Chinese import scares, ranging from toxic toys to tainted pet food, reports of contaminated drywall from that country have been popping up across the American Southeast. Chinese companies use unrefined “fly ash,” a coal residue found in smokestacks in coal-fired power plants in their manufacturing process. Fly ash contains strontium sulfide, a toxic substance commonly found in fireworks. In hot and wet environments, this substance can offgas into hydrogen sulfide, carbon disulfide, and carbonyl sulfide and contaminate a home’s air supply.
The bulk of these incidents have been reported in Florida and other southern states, likely due to the high levels of heat and humidity in that region. Most of the affected homes were built during the housing boom between 2004 and 2007, especially in the wake of Hurricane Katrina when domestic building materials were in short supply. An estimated 250,000 tons of drywall were imported from China during that time period because it was cheap and plentiful. This material was used in the construction of approximately 100,000 homes in the United States, and many believe this has lead to serious health and property damage.
We provide visual drywall inspections at an additional fee. We offer advanced testing if Chinese drywall is suspected.
