My unit was recently reconstructed after a leaking roof caused water damage from the 3rd floor down to ours on the second floor. Our entire ceiling was damaged as was the unit above ours top to bottom. They replaced everything, walls, ceiling and the 3rd floor floor above us. Now we hear EVERY step they take ( we had previously heard nothing in the 6months we lived here, very quiet). It's loud and keeps us up at night. The walls rattle at times. Feels like insulation was not put in or the sub floor was not installed properly. Does my landlord have to fix this since it is now a problem and is impacting our ability to sleep and enjoy the unit?
