Why a garage door chain won't close on its own track

A chain-drive opener pulls the door down along a fixed rail using a loop of chain wrapped around a sprocket at the motor end and a pulley or idler at the door end. If that chain stretches, loses tension, or jumps off either sprocket, the trolley carrying the door arm stops moving even though the motor keeps turning. From the driveway it looks like the door just quit partway — really it's a mechanical disconnect between the motor and the door itself.

La Porte's housing stock runs wide — a median build year of 1985 alongside a documented pocket of small 1940s frame houses in the older parts of town.

Some doors with this problem actually have fix a garage door chain replacement in La Porte instead.

What causes a garage door chain to bind near the bay in La Porte

A commercial foundation-repair source describes La Porte's ground as sandy overlays mixed with clay closer to Galveston Bay, shifting to pure Houston black clay further inland — and the same source points to faster slab-perimeter erosion near Sylvan Beach and the Ship Channel where wave action and rainfall overlap. That kind of ground movement can pull a door frame slightly out of square over time, and a rail bolted to a frame that's shifted is a rail that no longer holds the chain in a straight line, which is exactly the setup that makes a garage door chain won't close complaint keep coming back on the same door.
