CPSC Releases: Guidance on Identifying Problem Drywall in Homes
May 21st, 2010 7:28 AM

With so many companies popping up to offer testing, inspection, and remediation for Chinese drywall, it's no wonder the Federal Trade Commission (FTC) has published a warning: "Don’t Get Nailed by Bogus Tests and Treatments". The CPSC also recently released guidelines to help bring some standardization to the inspection, testing and remediation of possible Chinese Drywall installations. Hopefully, these guidelines will bring some peace of mind to those who have been wrongfully told they have Chinese drywall. For those who are unsure whether or not they have Chinese drywall, these guidelines may help determine if Chinese drywall is present.

Griffith Home Analysis has long-established relationships with accredited environmental labs. We have been providing residential environmental testing for nearly twenty years and don't take take it lightly. The CPSC recommended drywall tests measure for contaminants as low as 10 parts per million. As a result, we leave the accuracy of these types of tests to qualified chemists. We do not perform onsite drywall tests as we have found some of these types of tests to be inaccurate.

We have discovered, just as the CPSC has suggested in step one of their new guidelines, that a visual inspection of the accessible drywall areas and the home systems' accessible metal components is the best place to start to determine if the possibility of Chinese drywalls existence in a building. Looking for possible markings of Chinese drywall or the corrosion resulting from Chinese drywall has proven to be our best tip-off that a home has Chinese drywall.

Visual identification can be difficult since most of the drywall manufacturer markings are obscured. Most views of the drywall manufacturers stamps are limited to partial stamps on the back of the drywall, pieces of the boards end tape or partial UPC numbers. We rely on our database of information built from hundreds of drywall inspections and first hand information from labs, drywall manufacturers, drywall distributors, builders and developers to help sort the limited information obtained in a drywall inspection.
