I live on the 2nd floor of a 3 story apartment building. Once the weather got cooler in October (It's in California, so it's not THAT cold.), the floor above began making really LOUD cracking noises when the tenants above walk around. The cracking noises are loud enough to wake me and the sound ripples across the ceiling. It even jumps from one room to another. That is, they may step on one area in the living room above, and the crack travels across the width of the living room and into the bedroom.

The maintenance man said the floors are of wood with concrete over top, and then there is carpeting on top of the concrete. So, these are not wood floors they are walking on and creaking as wood sometimes does.

There are no visible cracks in my ceiling. I am concerned of the structural safety of the floor above as well as the noise is driving me crazy. What could possibly be wrong with the floor above and how could they fix it? (As of now, there are unwilling to do anything.)

Thanks for any help.

Concrete floors flex as do metall and wood floors. You ight think concrete is totally rigid but it is not. Flexing and noise are not necessarily an indication of a problem. If you are really worried that it will fall on you then I'd suggest you call the city or county building inspector and tell them what is happening. Folks in your state take things like this seriously.

I have the same problem, it sound like a lightening and thunder storm, it wakes me up when they walk around it's so loud, I can't even be in my living room when they are home... I am now sleeping in my walk-in closet... to try to get enough sleep... they are up till 2am every night and it's making my life a nighmare, LL could care less, told me "move out, if you don't like it"... help!.
