Defective Drywall Remediation Assessment
Learn More

Defective drywall was introduced to the U.S. as early as 2002 and was used in new construction, additions, and renovations of pre-existing houses until about 2008 with most used in the 2004-2007 timeframe. As the problems caused by the off-gassing of sulfide gasses became apparent, importation of the problem drywall was cease and remediation activity was initiated.

The problem drywall and all drywall dust needs to be removed and residue of the sulfur gases need time to gas-off from wood framing and flooring materials prior to re-finishing the structure with known non-problem drywall.
