Winnetka's median household income sits above $250,000, and that changes the math on a garage door call before the truck even leaves Skokie. At that income level, most owners aren't debating whether they can afford a new door - they're deciding whether an old one is worth saving. The answer usually comes down to age, not price. Winnetka's housing stock has a median build year of 1938, decades older than the 1963 median across the rest of the service area we cover. A door and opener installed or upgraded on a house from that era is more likely to be running hardware nobody has manufactured in years: odd-width track, older extension spring setups, drums sized for panels that don't match anything on a current supplier's shelf. On a newer house, a repair is nearly always the right call. On a 1938 house with original bones, we often end up telling the owner that replacement costs less over five years than keeping a spring or cable system alive on parts we have to special-order. We'll say that plainly on-site - we're not going to sell a repair we don't believe in just because it's the smaller invoice.
