i ran a google search for this, and came up empty. . .so i'll post this and wait for the flame. . . *G*
my wife and i bought a home 3 years ago. at the time, the floors were rock solid and squeak free. since then, in the high to medium traffic areas we have noticed sagging in the floor between the TJI. . . the spots directly over the TJI are solid, and it seems that it is limited to certain sheets of the Oxboard. IE: you can sag on one sheet, and feel the seam with the next sheet and that one is solid.
what are my choices here. i am contemplating ripping up the carpet and overlaying with 3/4" ply gloo'd n' scroo'd. is this my best bet? i don't really want to rip out the finished ceiling in the downstairs. or, in the long run, is it going to be cheaper and easier to do just that and place cross members between the TJI?
