I have an excessive amount of moistue in my slab home every fall. I have
had a french drain installed all around the perimeter of my home.I have
had the house checked for plumbing leaks.I have narrow overhangs with
vinyl covering with air holes. The moisture shows up in only one of my
registers....but goes away after running a dehumidifier constantly for a
couple of weeksand does not return until the next fall...any suggestions?
