lewisburg west virginia I have new house now 1 yr old, popping noise from walls and floors sometimes it sounds like a gun going off. contractor figured out that truss's should not be nailed too interior walls. walls pulled away from floor 3/8". still have popping noise not as bad. same contractor built house next door has very similar problems, but worse. is this normal or will this become an old house with all the noise. I understand that wood shinks and expands,but should I expect this for the life of the house.enjoy watching the show for many years about 20. contractor says house will pop for ever, it's funny the house in kentucky never popped. or will the pop go away, believe when cold hits the noise will pick up again. thanks doug
