A door that's run fine for fifty years doesn't fail because of one bad day - it fails because torsion springs are rated for a cycle count, and a spring installed when the house went up around 1970 has been through more open-close cycles than a spring on a house built in 2005. Nobody tracks that number, but the age does the math for you. Add Tennessee's cold-moderate winters, where metal contracts and lubrication thickens, and a spring that's marginal in October can snap in January.
We drive out from Smyrna, about 19 miles, so we're not a same-block call - that's worth knowing before you call, not after. It means we plan the trip with the parts we expect to need based on what you tell us about the door's age and symptoms, rather than showing up and hoping the van has the right drum size. For a house dating to 1970, we ask about the opener's age and whether the springs have ever been replaced, because that one answer changes which parts we load before we leave.
