Rebuilding a Mold Ridden Firewall

Thursday, September 19th, 2013 by George Alley

After being hired to address moisture concerns in a customers crawlspace, we found the sheetrock firewall separating their unit from the neighbors to be heavily covered in mold.  At the customers request, we tore out the existing sheetrock and scrubbed and treated with joists with fungicidal solution.  After that dried, we ran our 12 ml “pinkie” material up the joists to seal the crawlspace from the neighbors.  We then replaced the bottom panel close to the soil with Durock concrete board and the top panel with “purple” mildew resistant gypsum board.  All the joints were sealed with fire rated compound.  On top of that, we added another layer of pinkie material followed by our SilverGlo insulation board, which is what can be seen in the “after” photo.  The goal of this treatment was to create a healthy crawlspace environment that meets both fire and insulation building codes.
