The complex that I live in is pretty good for the most part, except that the second story floors are all creaky. When I lived on the first floor, I found it annoying to hear the person above walking about, but never complained.
Now, I live on the second floor, and I'm the one creaking about, regardless of how I might tip toe. The neighbors in this building are much more cantankerous than in the other building, because if I make the slightest sound, they start banging on the walls or my floor.
The other night, I was standing in one place, working on my bedroom computer, when the person below started banging on my floor. The only possible reason was that when I shifted my weight, the floor would creak.
I spoke to the management about this, and they are suppose to send maintenance to screw down the floorboards, but that means moving a lot of stuff, so that they can lift the carpet.
Besides moving, is there any other way to solve the problem? Sound proofing is expensive, and would only work on the walls, not the floor.
