The U.S. Consumer Products Safety Commission (CPSC), in its final report on tainted drywall, has issued a set of updated recommendations that may lower the cost of remediation for some homeowners.

The updated remediation guidance is based on studies just completed by the National Institute of Standards and Technology (NIST) on potential long term corrosion effects of problem drywall on gas piping, fire sprinkler heads, and smoke alarms.
