Reactive (Chinese) Drywall Assessment

Reactive Drywall, also known as Chinese Drywall, is known to release sulfurous gases. These emissions, which have the foul odor of rotten eggs, worsen as humidity and temperature rise. This causes copper surfaces to turn black and powdery, a chemical process indicative of a reaction with hydrogen sulfide. Copper pipes, wiring, and A/C coils are affected by this process. More importantly, these gases are a potential health hazard. Home owners afflicted by these gases have reported symptoms including irritated eyes and throat, coughing, sneezing, difficulty breathing, bloody noses, and symptoms similar to those of bronchitis and asthma. The greatest amount of Chinese Drywall was installed in the state of Florida, followed by Louisiana. Homes built or remodeled between 2005 and 2008 are considered most at risk.

Proper detection of reactive drywall follows strict protocols guided by the Consumer Product Safety Commission and Department of Housing & Urban Development. The identification process consists of two steps. A walk-through visual inspection by EE&G’s trained industrial hygienists checks for blackening on electrical wiring, air conditioning components and copper lines, and determines the year & origin of the drywall. If installed between 2001 and 2008, tests are performed on walls and drywall samples to confirm high levels of strontium, sulfur, sulfide compounds, and copper blackening.

Once reactive drywall is detected, EE&G offers a chemical-free solution to this devastating problem. Our experts use professional equipment to extract the odor from a home within 24 hours. We have serviced over 2,000 homes without a single failure, enabling homeowners to return to their homes and enjoy a safe, odor-free environment.
