I have a small 1970's ranch in Central Pa, that we got suckered into about 5 years ago. The floors are plywood covered with carpet or vinyl. The problem is that the floors in the entire house make noise whenever anyone walks on them. Of course the heavier you are the more you hear. It's worsening with time, and now to the point of driving me crazy. I am only an amateur with house repair and looking for any ideas on how to fix, or even lessen the problem (if at all possible), short of ripping everything up. My wife had a stroke, and can't work anymore, so I'm looking for any cost effective way to treat or repair the problem. Thanks in advance, Bill from Duncansville, PA.
