The rest of the DeKalb area skews toward homes built in the 1960s and 70s, where most original garage door hardware has already failed once and been replaced with something more current. Elburn doesn't follow that pattern. With a median build year around 1999, a lot of these doors and openers are coming up on their first real failure now, not their third. That means we're seeing original torsion springs, original wall consoles, and first-generation opener safety sensors that were basic even when new.
Elburn's household income, at a median over $106,000, also runs well above the area average, and houses in that bracket tend to have more opener accessories bolted on over the years - keypads, smart-home tie-ins, battery backup units added after the fact. Those extras don't fail the same way the core hardware does, and troubleshooting an add-on wired into a 25-year-old opener is a different job than replacing a spring.
