Stamford sits in a cold, severe winter climate band, and that matters more for garage doors than people expect. Steel contracts in deep cold, and on a door hung from 1960s-era track with decades of paint buildup and dried-out rollers, that contraction is enough to bind a track that was already slightly out of plumb. You get a door that opens fine in August and chatters or jumps the track in January.
The age of the housing stock compounds this. A door and opener combination original to a 1968-built house has outlived its lubrication, its weatherstripping, and often its spring by a wide margin. Cold makes brittle rubber crack and makes a tired spring more likely to let go under load, because the steel itself gets less forgiving at low temperatures. This isn't a failure you'd expect to see as often in warmer climate zones, or in neighborhoods built within the last 15 years with code-correct bracket spacing and insulated steel doors from the start.
We're not saying every door from this era is a ticking clock. Plenty have been maintained and run fine. But if nobody's touched the spring tension or track alignment since the Nixon administration, cold is what finally exposes it.
