The housing stock across our service area runs from 1962 up through 2013, with a median build year of 1989. Most of the fourteen named areas we travel to - from Monticello out to Addis - carry that same 1980s-and-90s core, which matters more than it sounds like it should.
A door and opener from that era is usually on its second or third spring by now, and a lot of them still run openers with the original chain-drive motor and none of the rolling-code safety features added later. That's a different failure than what you see in the newer 2000s-and-later builds mixed into the same towns, where the complaint is more often a sensor or circuit board than a worn spring.
We don't guess which one you've got before we see it. But if your house falls in that 1980s-90s band that dominates the area, the first thing we check is spring tension and cable wear before we touch the opener - that's where the age shows up first.
