The door has suddenly gone heavy, lifts crooked, or there was a bang from the garage nobody could place
Why it happens
Manufacturer documentation lists exactly those as warning signs of a failing or failed spring, alongside a visible gap of about two inches in a torsion spring and noise that is new or unusual.
Why it matters
A snapped spring leaves the door too heavy to lift, and the same manufacturer documentation lists the injuries involved in handling springs as broken bones, lacerations, and facial and joint injuries.
Response
Spring repairs are one of Deadlock's published services: snapped or tired springs replaced, usually in a single visit, with the right spring for the door. Thom carries common torsion and extension springs, and a snapped spring gets priority because of what it does to the door's weight. On a two-spring door both are usually worth doing at once, since they wear at the same rate.
