Across the area we serve, houses went up mostly between 1951 and 2008, with the median build year landing at 1978. That's a fifty-plus year spread, and it matters because a door's hardware tells you its decade almost as reliably as a permit record would.
Most of the stock, across the eleven named areas that make up this base, is 1960s-to-70s construction. That generation of garage came with a single torsion spring mounted center-shaft, a steel section door with no insulation, and - if it was ever automated - a chain-drive opener bolted on later rather than wired in from the start. The springs on those doors are thirty, forty, fifty years past their wind-cycle life even if nobody's ever had a problem, because the problem shows up all at once, not gradually.
The newer end of that 1951-2008 range brought double torsion springs on heavier insulated sections, steel rollers swapped for nylon, and openers with a safety-reversal sensor built in rather than bolted on. Those doors fail differently - usually electronics or sensor alignment before the spring gives out.
We don't have a block-by-block breakdown of which of the fifteen towns above skews older or newer within that range, so we're not going to guess at a specific decade for your street. What we can tell you on the phone, once we know the opener brand or the spring configuration, is which generation of hardware you're dealing with.
