Most of the housing stock in and around Pueblo dates to the 1960s and 70s, and that one fact explains a lot of our emergency calls. A torsion spring is rated for a set number of cycles - open and close - and springs installed when these houses were built are long past that number. They don't wear down gradually; they let go all at once, usually on a cold morning when the steel is stiffest.
That's the other half of it. Pueblo sits in a cold climate band with real winter severity, and cold does two things to an aging door: it stiffens the spring's steel right before the point of failure, and it thickens old grease on rollers and tracks until the opener motor is straining against resistance it was never sized for. That combination - old spring, cold snap - is the single most common emergency call we run.
We see the same pattern whether the call comes from Mesa Junction, the East Side, Belmont, or further out toward Pueblo West - houses from the same building era fail the same way, just on different mornings.
