I don't see how any wholesaler or vender of chinese drywall would willingly acknowledge to anyone other than perhaps their own attorney that they actually sold chinese drywall. Unless they're couillon. Marc I agree, just calling someone that just randomly answers a phone is not the most scientific way of figuring out if a particular house has tainted GWB. Even if they did ship bad GWB, they would not tell you. Heck the person answering the phone probably did not work there 5 years ago, and if he did, was he the one who placed the orders from the supplier? I doubt it. Look to the house to tell the story. If the copper is lightly tarnished, it could be location near the beach. On the other hand, it could be 20 sheets of GWB out of 600 in the whole house. If there is heavy corrosion on copper in the house then it is a possible hazard to people. Regardless of which the building systems are compromised. How would you feel if you bought a new house and had to replace the pipes, HVAC, and structural components every 5 years? Should the buyer be strapped with this higher maintenance requirement? Peopleââ¬â¢s health is another issue all together. Is it like Mold a decade ago? Maybe. Unfortunately, like the video a couple of weeks ago (in another string) about asbestos siding materials in the 40's and 50's it was the miracle product. Today we have a different opinion. Use caution when making the call on Chinese drywall. The repair is strip the house to the studs, replace the copper, and start over. It is a big call, and right now the question is who covers the price.
