Last winter was our first full winter in this home; this year it's been decidedly colder. The door in the garage on my side seems to now be freezing "often" to the floor. Is that a sign of a bad seal, something that should get replaced this summer? I know I have some humidity issues in the garage that I have yet to figure out (too cold to run a dehumidifier, tried that already, am sweeping it out more for now) and I think it's just condensation running down--I don't have a puddle under the door but when it does open I am finding a small patch of ice under the door. Wondering if the seal is going and a new one would stick less to ice.
