The pattern we see in Tea traces back to the build timing. A large share of these houses went up in the early 2000s, often with production-builder garage packages - a steel door, a basic chain-drive opener, a spring sized to code minimum rather than to the door's real cycle life. Twenty-plus years of severe cold-climate use later, that same hardware is working harder than it was designed to, especially on doors that get opened several times a day. It's not that anything was installed wrong - it's that it was installed to a budget, and budgets don't account for two decades of South Dakota winters. Household incomes in this area run well above the wider service area's median, and we mention that only because it shapes what we see on new installs: more owners here are willing to spec insulated doors and better openers up front rather than replacing with the same builder-grade unit, which is usually the right call for this climate.
