Well to answer my own question of what was under the living room floor we found out. 6.5 pounds of sugar sand drywall dust from the original installation and lots of yuck! It just seemed like the layed the carpeting without sweeping the floor. This was nasty. But tomorrow brings new carpeting and cleaning and replacing all the furniture and stuff we had to "make places" for. In other words we have one big room with nothing in it but a chair and a TV and 7 other rooms that you cannot even move in. Pure chaos I tell you. But it is only temporary and hopes are high for a cleaner more comfortable environment. Thanks to all of your words of encouragement bring this project to completion. Scott
