On a lot of the early-90s Cedar Mill houses, the complaint sounds the same: the door is louder than it used to be, sometimes with a grinding or rattling sound as it travels the track. That's usually worn rollers or a chain-drive opener that's never had its chain tensioned since it was installed. A second common one is the door hesitating halfway up, which points to a spring that's lost tension gradually rather than snapped outright - more common in doors this age than people expect.
Weatherstripping is the other recurring issue. In our cold, moderate winter climate, the rubber seal along the bottom of a 25-to-30-year-old door has usually gone brittle and cracked, letting in drafts and the occasional line of water. None of this is dramatic, but left alone it turns into a spring failure or an opener motor burning out from strain it shouldn't be under.
