The wider service area this company covers runs on a median build year of 1993, so a lot of towns on our route have doors fifteen or twenty years newer than what you'll find in Anoka. Anoka's housing predates that by two decades in the typical case, which means the original builder-grade steel rollers in this town have had that much more time to wear, rust at the stem, or crack in cold weather.
That cold matters here. This service area sits in a cold climate band on the severe end, and steel rollers without a sealed bearing are the first hardware to seize up once temperatures drop and the grease inside stiffens. A roller that's already worn from fifty years of use has very little margin left before the cold tips it from noisy to stuck. With roughly 7,422 households in Anoka against the roughly 81,000 across the full area we work, a lot of original hardware from that era is still out there quietly wearing down, not yet loud enough to call about.
