Elgin's housing stock runs 1956 to 2009, with the median build year landing around 1986, and most of the doors on those original tracks still carry the steel rollers that came with the house. Steel rollers were standard equipment through the 1980s and into the 90s, which covers most of the 61 named areas in this service territory. They ride on a bare steel stem with no bearing, so every open and close grinds metal against metal.
The cold moderate climate band this area sits in makes that worse, not just slower. Steel contracts in winter, and the grease packed into an old roller stem stiffens or dries out entirely below freezing. A roller that rolled fine in August starts grinding, catching, or dragging by January. That's not a coincidence of age alone - it's 30-plus year old steel meeting a real winter every year, twice a day, for decades.
Houses built later in that range, into the 2000s, often shipped with nylon rollers instead, which don't seize the same way. But even those wear out eventually, and once the roller shell cracks or the bearing seizes, the door starts telling you about it - usually right when it's coldest and you're in a hurry to get to work.
