Popping sounds in our house
I was wondering if I could get some much needed insight. We bought a home (in Mississippi) last October. It was built in 2002 (on a slab). When we first moved in, we didn't notice the popping sounds near as much (every now and then, but I know that all houses will make a shifting sound). However, the sounds have gotten much worse.
They tend to occur in the same places, and the majority of them are where the wall meets the ceiling. We have trace ceilings in the main bedroom and the living room, and the house has a large attic. A lot of times, the sounds occur during the same time frame -- when the temperature changes throughout the day. The sounds seem to be the loudest around 11:00pm-midnight. Sometimes it sounds like a muffled firecracker (at their worst). From what I've read about this, it is a result of expansion/contraction of the boards when they respond to temperature fluxuations. This would explain why it seems to do it when the outside temperature changes.
Although the majority of the sounds occur where the wall meets the ceiling, there is one spot in our bedroom where it comes from the inside of the wall. And rarely, but sometimes, I'll hear the sound begin in one area, and "run" across the ceiling.
We had someone come and look at the problem a few months ago. In the attic, they added some more support boards to run across the vertical boards (sorry, my construction lingo isn't up to par). We also noticed that some of the vertical boards had become loose from their nails -- so, they screwed them back in place. Either this particular problem did not exist when the house inspection was conducted, or it went un-noted.
My main concern (and nightmare) is that we'll have to just live with this problem. Other posts I've seen in other chatrooms is that this is in fact the case. If so, my nerves will soon be shot. My other wonderment is that the previous seller knew about the problem, but didn't disclose it. If so, I would obviously be angered -- but I'm sure proving it is a near impossibility. We are waiting on our guy and his crew to come back to reassess the problem. Hopefully they'll be here within two weeks.
So, have any of you run into this same problem, and what did you do to fix it? If fixed, was it expensive/labor intensive?
