we have one spot in our bedroom where the floor squeeks. If i get up in the middle of the night the spot squeeks so loud it wake my wife and that's not fuuny. when you have to go you have to go! Seriously, we had our home built 4 years ago by what we thought was a very good builder. Our bedroom is on the 2nd floor so we can't get between the ceiling on the first floor to the hardwood flooring in our bedroom. Any help would be greatly appreciated!
