Across these 24 named areas, the housing is mostly from one long building wave: 1958 through 1999, with a median build year of 1981, and the bulk of it dating to the 1980s and 90s. That matters more than it sounds like it should. A door and opener installed when a house was built in 1981 is well past any reasonable service life by now, whether the spring ever snapped or not.
What this means in practice is that a large share of the doors we see, no matter which of these towns the call comes from, are original or close to it: single-layer steel panels, galvanized torsion springs long since fatigued, and openers with chain drives and worn sprockets. Newer construction in the mix tends to have insulated doors and better-sealed openers, but it's the minority here, not the norm.
We can't tell you the exact year your specific house was built or what door came with it - that's not something we have on file before we see it. What we can tell you is that if your door is original to a home from this era, it's a reasonable bet the spring, rollers, and opener are all near or past the end of their working life.
