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

There's a local angle to a loud bang from the garage in Longmont: the area's freezing cold and heavy snow is hard on garage doors — cold snaps brittle springs, and ice freezes doors shut. Our Longmont techs see these failures spike around every winter cold snap, so they track down the real cause instead of masking the symptom.
