Chinese Dry Wall
You might be concerned that your home could have defective Chinese drywall if it was built or remodeled during the years 2003-2009. That's why during every inspection, we are looking for the 3 indicators that would warrant a home to need further testing and have multiple samples of the drywall be sent to a lab in order to get a definitive diagnosis.
The 3 big indicators of the Chinese Dry Wall: rotten egg/sulfur smell, electrical shortages, HVAC problems. If a home does not have any of these present, then we would not recommend any further testing.
Contrary to popular belief, there are no on-site tests that can give you a definitive answer on whether your home may have this drywall.
