Hanover Park's median home was built around 1976, which puts most of this town squarely in the mid-70s wave of construction rather than the older or newer edges of the wider service area. That one decade matters more than it sounds like it should. A house built in 1976 usually came with a single-panel or early sectional steel door, an extension-spring setup mounted overhead rather than the torsion bar you'd find on a lot of newer builds, and an opener that's been swapped out at least once, sometimes twice, by the time we get the call. With 11,210 households in town, we see this same setup often enough that it's the default assumption, not the exception. Compare that to the broader area we cover, where housing spans 1938 to 2009 - Hanover Park sits right in the thick of the older-hardware end of that range, not the newer end. That's the starting point for almost every job we take here, and it's worth knowing before a tech shows up: if your door still has the original springs, they're pushing 50 years old, and that changes what a repair looks like versus a straight swap.
