Use of vacuum to rid home of defective drywall particles insufficient March 10, 2010

The combined federal Chinese drywall trials taking place in Louisiana are expected to produce far-reaching implications.  The initial trial was aimed at shaping the proper cure for homes affected.

We reported earlier on an article by The Herald Tribune that noted two critical issues that involve measures which were once thought adequate to play a role in curing homes.  The severance of wiring when exposed, and the usage of vacuums to remove drywall particles after removal.

In a recent article we explained how snipping off exposed wires was previously and incorrectly thought to be an effective solution with regard to that component.  Lennar Corp. has reportedly taken heed of the opinions of experts on the matter and no longer uses this method when addressing affected homes.

The other issue, the focus of this article, is the removal of “traces” of drywall particles (and the smell it left behind) after a home is “gutted.” (Note: Gutting refers to the removal of all components in the home that have been contaminated or affected by defective drywall).

Ray Philips, an executive officer with home builder Beazer Homes, noted that  his company’s approach was that vacuuming the home was not enough.  His company has resorted to using pressure washing homes before rebuilding them.  Other scientists elaborated; there needs to be a step that goes above and beyond merely vacuuming in order to remove all particles and possible contamination.

The Herald Tribune recently reported on a visit to a Lennar home.  Read the article here for a description of that visit.
