Smyrna is a smaller piece of the territory we cover out of Dover, with about 4,873 households, and the housing here skews newer than a lot of the surrounding towns. Median build year runs around 2002, which puts most garage doors here on steel torsion systems with factory openers rather than the older extension-spring setups you still find on the 1960s and 70s stock closer to Dover itself. That doesn't mean Smyrna doors don't fail, it means they fail for different reasons. Newer torsion springs are rated for a set number of cycles, and a door opened twice a day for twenty years is due for a break whether the house is new or old. We also work inside a COLD severe climate band, and a steel door built in 2002 still has steel hinges and a steel track that contract in a hard freeze the same as any other year's door. Cold tightens tolerances on rollers and binds a track that was fine in October. The newer stock here also tends to run heavier insulated doors, and a heavier door that loses a spring puts more strain on the opener's gears trying to compensate, which is a second failure riding on the first one.
