Posted by Allison Bailes on July 23, 2020
Back in the summer of 2005, I got a call to figure out a moisture problem in a new house.  The homeowners took me into the master suite, where the first thing to catch my eye was the towel folded neatly on the floor.  It hadn't just fallen out of the laundry basket; it was there to catch the water...
