Identification Method The identification process is two steps:
- An initial or threshold inspection to find visual signs of metal corrosion and evidence of drywall installation during the relevant time period, and
- The identification of corroborating evidence or characteristics.
Step 1: Threshold Inspection
Visual inspection must show:
- Blackening of copper electrical wiring and/or air conditioning evaporator coils; and
- The installation of new drywall (for new construction or renovations) between 2001 and 2008. A positive result for this step (including both criteria) is a prerequisite to any further consideration.
Step 2: Corroborating Evidence
Because it is possible that corrosion of metal in homes can occur for other reasons, it is important to obtain additional corroborating evidence of problem drywall. Homes with the characteristic metal corrosion problems must also have at least two of these corroborating conditions if the new drywall was installed between 2005 and 2008. For installations between 2001 and 2004, at least four of the following conditions must be met. Collecting evidence of these corroborating conditions will in some cases require professional assessors and/or testing by analytical laboratories.
- Elemental sulfur levels in samples of drywall core found in the home exceeding 10 ppm; 6
- Corrosive conditions in the home, demonstrated by the formation of copper sulfide on copper coupons (test strips of metal) placed in the home for a period of two weeks to 30 days or confirmation of the presence of sulfur in the blackening of the grounding wires and/or air conditioning coils;
The predominant stucco in Flagler/Volusia and St. Johns is hard stucco over block or plywood/osb. It is common to find cracks in the stucco due to poor installation or maintenance. While the cracks are not structural, they can allow water to penetrate into the home. H2H has special meters that can determine whether the substrate has been compromised and needs to be fixed.
