Covington's housing stock centers on 1994, noticeably newer than the 1983 median across the wider service area we cover from Tukwila. That decade-plus gap matters more than it sounds like it should. A house built in the early '90s came with a different opener class, different track spacing, and door panels sized to different framing standards than what went up in the '70s and '80s a few miles over. With roughly 7,324 households in Covington, you've got a fairly consistent build era running through most neighborhoods, which means the failures we see here cluster too - not the scattered mix of eras you'd find in an older suburb. If your house was part of that mid-90s wave, your door and opener are likely original or one replacement removed from original, and both are now old enough to be wearing out on schedule rather than by accident.
