Chinese Drywall Inspections

​

Chinese (corrosive) drywall refers to the drywall building material manufactured in and imported from China between approximately 2005 and 2009. Small amounts of drywall that was installed from 2001 to 2004 has been found to be corrosive. This corrosive material was used in homes and commercial buildings across the United States causing many environmental concerns including damage to air conditioning parts, electrical wiring and parts, copper plumbing, appliances and electronics.

The suspect drywall contains non-essential metals and minerals, such as sulfur, strontium and iron which in warm and humid climates can emit sulfur gasses that create noxious odors and damage copper and other metals. Even small amounts of this corrosive product can seriously affect occupants’ health and severely reduce the value of the property.

In addition to identifying the corrosive drywall, Alpha Environmental can provide testing before and after remediation of the corrosive drywall. Post Remediation Verification (clearance) testing and certification can add value to the property for resale and insurability.
