The Consumer Product Safety Commission (CPSC) and the US Department of Housing and Urban Development (HUD) released revisions to their Chinese drywall remediation guidelines March 18, 2011. 

The most noteworthy change to their remediation guidelines is that the complete removal of electrical wiring in homes contaminated with the defective Chinese drywall is no longer recommended.  According to an article in, the decision came after the Scandia National Laboratories in New Mexico simulated 40 years of electrical wire exposure of the corrosive sulfide gases found in the problem Chinese drywall, but found no safety risks. This decision could greatly reduce the cost of remediating affected homes.

The replacement of receptacles, switches, ground-fault circuit interrupters, and circuit breakers is still recommended due to corrosion of exposed contact surfaces.

According to, it is unclear if the Chinese drywall homes chosen for the Knauf remediation pilot program, which calls for the replacement of all electrical wiring, will be affected by these changes. 

The CPSC has received approximately 3,810 reports of problem drywall in 42 states.
