South Elgin's median household income sits at $123,744, well above the wider service area's $111,898. That number matters more than most homeowners realize, because it changes where the repair-or-replace line falls. On a lower-income block, a $400 spring job on a tired door makes sense for another five years. Here, with houses running newer and household budgets running higher, we see more owners skip the patch-job stage entirely and go straight to a new door once the old one starts showing its age.
The housing stock backs this up. Across the broader service area, homes date from 1956 to 2009 with a median build year of 1986, and most of the stock is 1980s-90s construction. South Elgin itself trends newer, with a median build year around 1996. That means a lot of these garage doors are late-90s builder-grade steel: single-layer, minimal insulation, steel tracks that were fine for the climate at install but are now twenty-plus years into a cold, moderate freeze-thaw cycle. The door isn't failing because it was installed wrong. It's failing because it was built to a budget spec that's aged out.
