Minnesota's cold climate is the same whether a house was built in 1975 or 2002, and it still does the same things to a garage door: it stiffens springs, shrinks seals, and makes nylon rollers brittle enough to crack on a cold start. What's different in Lake Elmo is that the springs we're replacing are usually original factory-spec torsion springs rated for a 2000s-era door weight, not a patched-together mismatch from decades of partial repairs. Median household income here runs $153,407, noticeably higher than the broader service area, and we see that reflected in the openers people choose - more Wi-Fi-enabled units with battery backup, more insulated steel doors rather than bare single-layer panels. The failures are still mechanical: a spring that's cycled out, a sensor knocked out of alignment, a cable that's frayed at the drum.
