Across a service area with 40,373 households and 28,075 owner-occupied houses, the calls cluster around a few things. Broken torsion springs top the list - with median household income here at $92,292, most owners fix the spring rather than replace the whole door, and that's usually the right call on a door from the 80s or 90s stock.
Opener failures come in close behind, especially on houses built in that 1958-2012 window where the original opener is long past end of life and a homeowner is on their second or third unit. Cold-weather callouts tick up in winter - this area sits in a cold-moderate climate band, and a stiff, frozen track or a spring that's lost tension in low temps is a common January call whether you're in La Vergne or out past Rockvale.
Track and roller wear shows up more in the older pockets mixed through Eagleville and Rural Hill, where original steel rollers have been grinding for decades. We don't stock every obscure part for a 1960s-era door on the truck - some of that hardware has to be special-ordered, and we'll tell you that up front rather than stringing out a visit.
