Door keep flying open in the cold weather
We have a steel door from the house to the attached garage with no lock. Door opens to a small a laundry room with a another interior door leading into the kitchen.
During the winter months (in Michigan) I will suddenly notice a cold draft in the house and sure enough, the door to the garage is wide open for no reason. This happens every year.
It seems to help when you push the door shut without using the door knob versus turning the knob to shut the door (if that makes sense).
Does anyone know this happens? Since it is a steel door -- it can't warp, right? Is the seals shrinking the cold???
What should we do to fix it short of replacing the whole door? DH was thinking of having a dead bolt installed but now sure how diligent we would be about locking it since we are in and out all day.
