What is Chinese Drywall?
Chinese, or Toxic drywall, was installed between 2001 and 2009 when there was a drywall shortage in the U.S.. This was caused by the housing bubble burst in 2008, as well as, several hurricanes in the southeast. Homes could have been remodeled with toxic drywall or built with it.
Toxic drywall releases sulfur gases that are particularly emitted during high humidity. The sulfur gases can create health concerns in both the short term and long term.
With short term exposure, a person may experience:
- sore throat
- eye irritation

How to tell if you have Chinese Drywall
The sulfur gases released by toxic drywall creates clues that allow us to determine the probability of having Chinese drywall. Here are some of the signs to look for:

- rotten egg smell inside the home
- health symptoms listed above experienced by the home’s occupants
- Chinese lettering or “Made in China” inked on backside of drywall panels (check the attic for this)
It is important to note that some homes may only include some portions of problem drywall depending on remodeling, or how the shipments of drywall came in during construction.
If you meet the above criteria it is recommended to test by a laboratory, or have a qualified home inspector evaluate the home for a professional opinion. We can complete contaminated drywall tests for you in West Central Florida and Southwest Florida.
