Problems with Chinese Drywall (Chinese Dry Wall)

It's important to note that not all homes that contain Chinese drywall are problematic.  However, your home may have tainted drywall even though you do not notice a smell or do not have any symptoms yet.  Time is of the essence because your builder may have a limited amount of funds to make repairs and the deadlines set by federal district litigation for claim submission

Knauf Drywall Remediation Program (Knauf Dry Wall)

Knauf is one of the manufactures that has actually started a remediation program to fully replace all the drywall and restore the property.  Other manufacturers may follow suit.  Therefore, it is critical to not only know if you have corrosive drywall but which manufacturer it is.  Most homes have multiple types that can complicate the assessment and claim.  It is critical to get properly documented and have your claim submitted into the MDL.  Contact us for more information.

Preservation of Evidence
- If you have tainted Chinese drywall and are planning to remediate, repair or remodel your home, preservation of evidence is needed to protect your interests if you are pursing any type of legal action.    The Pre-Trial Order No. 1(I) through the United States District Court Eastern District of Louisiana must be strictly followed.  Having an independent third party professional properly preserving your evidence is critical.  If this is not performed or done correctly, you could jeopardize the evidence.  The manufacturers and suppliers may claim the evidence was damaged and avoid compensating your for your losses.  For more information please go to our menu and "click" on "Preservation of Evidence".

Environmental Certification aka Post Remediation Verification (PRV) -  Would you trust the company that you sued to manage the remediation and the certification to ensure it is done properly?  Whether getting remediated through the Knauf Pilot Program or hiring your own GC, we can customize our services to meet your needs.  Click "Remediation Clearance" on the menu bar for more information and what to watch out for.
