Most of the doors we open up in Issaquah are original or close to it. Housing in this service area was built mostly between 1962 and 2005, with a median build year around 1983, and that range covers the bulk of the 34 named areas we work across, from Olde Town and Gilman right in town out to North Issaquah and Squak Mountain. A door installed in the early or mid 1980s has been through four decades of temperature swings in a cold-moderate climate band, and steel torsion springs are only rated for a set number of open-close cycles before they fatigue and let go.
Cold doesn't just stiffen the spring steel - it thickens the grease in the coils and in the roller bearings, which means the opener motor works harder every cold morning to do what it used to do without strain. Over years, that extra load wears the opener's drive gear and the spring at the same rate. This isn't a defect in any one brand or install. It's what happens to any torsion system built in this era, in this climate, once it hits its cycle limit. We see it as a pattern across the housing stock, not as bad luck on one street.
