The 2009 Chinese drywall controversy has been called a health and safety issue involving defective drywall manufactured in China and imported by the United States starting in 2004. Laboratory tests of samples for volatile chemicals have identified emissions of the sulfurous gases carbon disulfide, carbonyl sulfide, and hydrogen sulfide. These emissions, which have the odor of rotten eggs, worsen as temperature and humidity rise. Homeowners have reported respiratory tract infections, sinus problems and nosebleeds.
In homes with the defective drywall, copper surfaces such as pipes, wiring, and air conditioner coils corrode, turning black and powdery, a chemical process indicative of reaction with hydrogen sulfide.
With our experience in mold remediation, we have made it our business to become experts in dealing with this issue. We have developed protocols for removing the drywall, solving the plumbing and electrical issues and putting the home back to an uncontaminated state.
Mitch, the job that you and your team did on our windows and doors was top notch all around. The guys installing them really paid attention to detail, took however long it took to get each and every window right. On any other house, you can see where corners were cut, but the job you did on my house really shows that no corners were cut. Thanks for seeing it through to the end and doing such a great job. ![]()
