I would like to soundproof my ceiling without ripping down the old ceiling. The reason is that the old ceiling is holding up cellulose insulation. The cellulose insulation does a good job reducing conversation noise and keeping in heat. I have done some research on soundproofing for footfalls from an above apartment. It is suggested that you use two layers of drywall connected with green glue or a material like quietrock and that you attach this to the joists with sound clips, which essentially detach the ceiling from the joists. Typically it seems you are suppose to rip down the old ceiling and just start from scratch. After thinking about it, I don't see why you can just attach the clips to the joists without ripping down the pre-existing sheetrock. The ceiling will still be detached and you will have an extra layer of sheetrock to reduce noise. Am I missing something here? Also, if you must attach the clips directly to the joists, couldn't you just remove little sections of the drywall to expose the joist? The clips + the drywall furring channel should drop the new ceiling far enough not to hit the existing ceiling? Any feedback would be greatly appreciated. Thanks

All 3 of my bedroom ceilings and walls are plaster and the ceilings are all cracked with wave-like rumples across the ceiling; and the walls are beginning to do the same. I would like to remove the plaster ceilings and install sheetrock this weekend. My brother-in-law who will do the work, tells me it is a big job to remove the plaster from the ceiling. The bedroom is 152 sq. ft. He suggests that we repair the plaster. Does anyone have a suggestion on how best to proceed? And how do we do this? Help. Miss Stressed.:(
