Is a popping noise normal?
We've been in our house for about 8 months now and it seems that on one side of the house we hear a good amount of popping, especially early in the morning. We have a walkout basement home and the area we hear this the most is in an upstairs bedroom where there is an unheated shop below. Could it just be the difference in temperatures or is the house (still) settling? It gets to be kind of scary at 4:00 in the morning.
