Why Does My House Make Loud Cracking Noises in the Cold Weather?
With the bitterly cold temperatures we’ve had here recently, did you ever wonder why your house makes cracking or bumping noises during a cold snap? According to the Toronto Home Guide, extreme changes in weather temperature can cause shrinking in all exposed building materials. Many of its parts are exposed to warm environments (on the inside) and at the same time to cold environments (on the outside.) Outside parts of the structure are shrinking while inside parts are staying essentially the same. When parts of a building shrink quickly, stress is produced in the connections and joints, and when stresses are released quickly, a loud popping sound can be heard as one member moves against or away from another, or from the connectors.
