Bleeding sound between floors

[Sydney McCloud]

Tenant has notified me that the noise coming from the floors above is loud. I know that is probably just a normal and natural part of apartment living, but there is very squeaky floorboards right above the tenants bedroom, causing her sleep to be interrupted very early in the morning when my tenants has to wake up for work. particularly bad areas. Any solution for minor sound proofing fixes that may be able to work? This has been happening for a couple of months now.

You should research STC rating options. Older buildings likely have nothing but one layer of sheet rock between the floor boards/joists and lower level units. Newer construction is required to meet STC ratings. If you have sufficient ceiling height, a good option is to install a resilient channel system and 2 layers of 5/8 type X sheetrock. This will decrease sound transfer and vibrations. I've heard from some who will also use green glue between layers of sheetrock. This assembly will also meet the current Philadelphia fire rating assembly requirement for new builds so you could simultaneously make the building safer as well.
