The product, in the report: National Gypsum GridMarX Drywall

I live in Leesburg, Virginia. WCI built my home in 2006 and I purchased it as a spec house in 2007. I received a letter from WCI in 2009 indicating my home may have been built with Chinese drywall. I have a copper pipe in my basement that is corroded to the point that it’s pitting and I’m on public water. My wife has had numerous health problems, including respiratory issues. We’ve also had air conditioner failures and numerous electrical problems. However, so far I’ve only seen National Gypsum GridMarX drywall.
My home is large though (over 9,000 sq ft) and mostly finished so I know there may be multiple brands installed which I can’t see. I’m trying to find help in the form of testing to confirm that I have the problem. Unfortunately, I am experiencing a financial hardship and cannot afford testing. Would you be able to assist me? I tried to contact you about this in 2009, but never received a response.
Thank you,
[REDACTED]

The company’s comments, in its own words

(10/4/2011) NATIONAL GYPSUM COMPANY: National Gypsum Company submits that the indication that National Gypsum Company is the manufacturer of a product causing the problems reported by the Consumer in his home is incorrect and not supported by any information in the Report itself: • The Report states that the Consumer’s home was built in 2006 by WCI and that he received a letter from WCI in 2009 indicating the home “may have been built with Chinese drywall.” WCI Communities admitted it built a number of homes using imported Chinese drywall: “WCI believes that drywall manufactured in China may have been installed in certain portions of some homes that were built and sold prior to our Chapter 11 filing,” -- [REDACTED], WCI’s customer communication director, The News-Press, Ft. Myers, Florida, February 2009. • The Consumer notes that he has seen some National Gypsum GridMarX® drywall in his home, but acknowledges, “I know there may be multiple brands installed which I can’t see.” He also notes that his home is “large” – 9,000 square feet. There is no indication of actions, if any, taken to determine whether he has Chinese drywall in his home. The Consumer also states (at p. 2 of his report) that he has not had any of his drywall tested to determine whether it could possibly be a cause of reported corrosion and other reported problems. • Under circumstances similar to those reported by the Consumer in this instance, the CPSC has publicly reported that it did not have enough evidence to determine either (a) that homes were constructed with only domestic drywall, as opposed to Chinese drywall; or (b) that any of the drywall in the homes caused the reported corrosion in the homes. See U.S. CPSC, Staff Summary of Contractor’s Evaluation of Homes Reported to be Constructed with Domestic Drywall, at p. 5 (Apr. 15, 2011). It follows there is insufficient information to conclude that the Consumer’s home in this instance contains defective drywall, or that the National Gypsum drywall in the home is in any way defective. • The mere existence of National Gypsum’s product in an attic or garage, or even in other areas of a home, in no way indicates that such product is defective or is the cause of the reported problems. • National Gypsum Company Has Not Manufactured, Imported or Otherwise Distributed Chinese-Manufactured Drywall and Therefore Takes No Responsibility for Any Effects of Such Drywall. All drywall sold by National Gypsum is produced at its own manufacturing plants in the United States. • A CPSC-Sponsored Report Identified Elemental Sulfur (S8) as “Sensitive and Specific Marker of Problem Drywall”; But, Elemental Sulfur Is Not Detected in National Gypsum Company Drywall. EH&E Report 17402, Problem Drywall Assessment and Indoor Environmental Quality Evaluation, 144 Groesbeek Street and 4 Darden Street, Fort Bragg, North Carolina, at p. 73 (Feb. 7, 2011), available at http://www.cpsc.gov/info/drywall/ehefeb2011.pdf. • If the Consumer has National Gypsum Company branded drywall which he believes to be problematic, National Gypsum Company encourages the Property owner to contact the company and share information with it.
