We wanted to soundproof the walls by removing the sheetrock and putting in the insulation. When my dad removed

Question

the sheetrock we see that there is concrete in between the 2x4's. What can be done now? The wood is rotten pretty bad.

Answer 1

without seeing it, can you replace one 2X4 at a time and use treated lumber, and leave it without insulation... or if you want insluation... can you reframe a new wall just inside the room of the old one and insulate it!!!

Answer 2

If you plan to take down all the Sheetrock, I would say the easiest way is to take a heavy hammer and bust the Sheetrock between the studs. You can then get behind and use a prybar to pull it off the studs. If it is screwed to the studs, you will want to end up with the Sheetrock removed and the screws still in the studs. You then remove the screws. If the mold is only at the bottom, you might consider snapping a chalk line parallel to the floor 4 foot high. Saw across that line and remove the lower sections. That way you can replace the bad Sheetrock on the bottom and retape. You do want to get rid of the moisture that is causing the mold. That is another project all together.

Answer 3

Concrete between the studs? Maybe you live in a totally different climate or country than me but I've never heard of such a thing.

First off.. if there is any rotting wood it should be replaced. As far as soundproof... a material designed to deaden sound should be used instead of just insulation. There are many types available.. I would advise you to do some research on the different brands.

Answer 4

It's less of a problem than you think. If the 2x4's are rotten, and you cannot replace them with conventional screws to the concrete, use Liquid Nails, it'll work just fine. For the insulation, (using Liquid Nails) use 3/4" O.S.B., (oriented strand board), then cover it up with the drywall. You'll have a lot of sound and weather barrier.

Answer 5

Here is a question....wasn't the concrete soundproofing it already? It is much more denser than any insulation that you would be putting in there had the wall cavities been empty.
The concrete wall is holding up the wall, don't need no wood no more.

Answer 6

The wood needs to be replaced and put some sealer on the concrete to prevent any moisture from collecting on the wood and doing the same thing. You should be able to put insulation in and replace the dry wall, then. Good luck!
