LOUD creaking from drywall ceiling
Dave1

I have a 4 unit multi-family with apartments on the first and 2nd floor........

Extremely loud and high pitched creaks in the downstairs apartment when the upstairs tenant walks.

The floorboards have been screwed to the joists and suprisingly the sound is coming from the 5/8 inch drywall ceiling. Slight flexing in the joists (2x8) when upstairs tenant walks creates cracking and popping sounds all over the ceiling, easily waking downstairs tenant up at night.

Tried screwing the drywall ceiling to the strapping, which helps but not enough. Any thoughts on a solution???? May tear down the ceiling and try a different type of drywall. Are there Sheetrock drywalls anyone would recommend?

Drywall, to my knowledge will not squeak; probably look at the fasteners from strapping to framing?

Unless the extra space above the ceiling is needed or there are other reasons such as odd spacing, I've never saw the point in adding strapping- it creates a place where looseness can occur; it adds weight without adding structure; it's weaker than screwing the sheetrock directly to the joists, and you've only got 3/4" wood for the sheetrock screws to bite into where you once had 7" or more (although 3/4" should be adequate).

New codes require gluing as well as screwing sheetrock ceilings so were it mine I'd demo the thing and do it the right way this time. You may now need to add the 3/4" as furring (reuse the strapping) so the walls meet the ceiling but glue those on and use longer sheetrock screws to compensate. This will add some slight stiffening to the joists too. If I was really worried (or really bored) I'd sister the joists while it was open for even more stiffness and add bridging too. Never saw something fail because it was too strong!

Dave, did you find the reason for this? I guess Sombreuil_mongrel is right.
