If your home was built or underwent repairs and remodeling between 2001 and 2009, it’s possible that toxic drywall imported from China was used. Signs of Chinese drywall include the smell of sulfur, corroding copper and electrical wires, and more. At HomePro Inspections, we offer inspection and sampling options in order to determine if your home contains defective Chinese drywall.

Common Signs of Chinese Drywall

During the construction boom between 2001 and 2009, drywall shortages in the United States caused the building industry to import drywall manufactured in China. The following signs are commonly present in homes that contain defective Chinese-made drywall.

Copper Pipes Turning Black and Powdery

Copper turns black and powdery.

Odor of Rotten Eggs or Burnt Matches

Creates odor of rotten eggs, sulfur, or burnt matches.

Corroding Copper Evaporator Coils

Corrosion of copper evaporator coils in air conditioning systems.

Oxidation and Corrosion of Electrical Wires

Oxidation and/or corrosion of electrical wiring.

Metal Corroding in the Home

Corrosion of other metals present in the home.

Do You Need an Assessment for Chinese Drywall?

To help determine whether a property may have defective or corrosive Chinese drywall installed, the state of Florida has developed a case definition. To meet the current definition (12-18-09), follow the guidelines below.

Chinese Drywall

Criteria 1: Sentinel Indicators of Drywall Associated Corrosion

  • 1 The home was constructed or renovated with new drywall between 2001 and 2009.
  • 2 Observed corrosion of air conditioner evaporator coil exemplified by black corrosion on copper tubing components. The corrosion can result in refrigerant leakage making it impossible to cool the home requiring coil replacement. Coil failures indicative of this problem typically occur every 6 to 14 months.
  • 3 Observed metal corrosion, indicated by blackening of one or more of the following:
    • Copper wires, ground wires, and electrical connectors
    • Un-insulated and un-coated copper pipes and fittings
    • Chrome-plated bathroom or kitchen fixtures
    • Silver and copper jewelry
    • Mirror backing in bathrooms

If all three of the above indicators are true of your home, then the home meets the criteria for “possible case” of Chinese drywall and further investigation is recommended. A Chinese drywall assessment from HomePro will determine if your home meets the criteria for “probable cause,” at which time sampling is recommended for lab testing. Lab testing will determine if your home has a “confirmed case” of Chinese drywall.
