A loud bang from the garage in Rock Hill is the unmistakable sound of a torsion spring snapping. The door will likely feel very heavy or refuse to open.

In Rock Hill, the weather is often part of the story behind a loud bang from the garage. Months of heat and humidity mean humidity corrodes hardware and falling limbs dent panels across York County — exactly the kind of wear a local tech knows to check first.
