February: Frost Heave and the Apron Outside Your Door
The frost line in northern Illinois runs deep enough to move concrete.
Frost penetrating below a slab or apron lifts it, and it settles again in spring. The practical effect on a garage door is that the closed position moves seasonally: the door binds, or reverses on closing, or leaves a gap that was not there in autumn. Owners adjust the opener force to compensate, which masks the symptom and puts strain elsewhere. A fault that appears every February and clears every April is frost, not a failing mechanism.
