The complaint we hear most from this stretch isn't a broken spring - it's an opener that runs but won't fully close, or closes and immediately reverses. On doors from this build era, that's usually the safety sensor pair going out of alignment, sometimes from a small settling shift in a slab poured in the late 90s, sometimes just from a knock. It reads to homeowners like a big electrical problem. It's usually a five-minute alignment fix once someone's looking at the actual sensors instead of guessing at the opener.
The second most common call is a door that's noisy but still working - worn rollers on the original steel track, which is about the age you'd expect wear to show up on a door installed around 1997. That one's not an emergency, but it's the kind of thing that turns into a cable failure if it sits for another few years.
What doesn't fit this pattern as often here: the sagging wood panels and rusted-through track sections we see on much older doors elsewhere in the service area. This stock is younger, and the failures follow that.
