I have just purchased a brick one story home built in 1997. The living room has a vaulted ceiling. In this room the ceiling and walls constantly pop and creak. Others have told me that it is possibly coming from the wood expanding and contracting with the temperatue. Sometimes the popping noise is so loud it actually wakes me up during the night. I had the home inspected prior to buying it and there were no problems discovered in the attic.I have lived in several houses but have never experienced anything such as this. Any suggestions on what may actually be causing this and how to stop it? Thanks
