Wheeling, WV homeowner Amy L. built her home with a crawlspace underneath it. Crawlspaces are a common method builders use to hide electrical and HVAC work. Crawlspace science has changed considerable over the years. Crawlspaces are normally known as dark, damp, and smelly places under a home. This is because outdated building codes permitted crawlspaces to be ventilated. We know today that this isn't the ideal solution. We close the vents and insulate the walls using SilverGlo wall insulation. Then we prevent moisture from seeping up through the ground using are CleanSpace liner to line your crawlspace.
