Re: any chinese drywall experts out there?
between 2001 and 2008 is suspect for CDW. If you are looking at houses or major remodels from that time, you ought complete a full visual check at all of the outlets, light switches, copper wires to circuit breakers, copper tubing for water, and copper tubing on AC or fridge cooling coils. The chinese dry wall emits sulfur which oxidizes onto copper (or silver and some "soft metals" which I take to mean lead or iron other than stainless). You may smell the typical sulfur odor, too. You'll see a black oxidation, rather than the typical shiny copper.
Today on my inspection of a house on the lake, only the outlets and switches had the typical black oxidation. Bummer, as the main circuit breakers, coils etc were normal.
In addition, you should try to visualize the backside of the drywall, such as in the attic or crawl space, and if you see Made in China, or Knauff, or Tianjin - be very cautious. We saw insulation with the Knauff name (not implicated with fiberglass, though)
This and more info is on the Consumer Product Safety Commision website - it is very good.
Caution in that there is currently no formal "certification", so don't let someone try to sell you any kits or say your house is safe or not. CPSC writes a simple algorthim about when you should send any actual samples of the drywall.
My inspector was good and knowledgable - but before you hire one, as I learned today, you can simply unscrew the fixtures and look for yourself - just be carefull about the hot-wires. He too acknowleged that no one should certify "good house or bad" but his expertise was useful.
Good Luck!
