Plum has roughly 10,692 households and a median household income around $98,475 - notably higher than the roughly $62,874 median across the broader service area. That income level tends to track with homeowners who've already replaced an opener or two since the house was built, rather than ones still running the original unit from move-in day.
The climate here is the same cold, severe winter band that covers the whole region, and that doesn't change block to block. Cold snaps stiffen torsion springs, shrink weatherstripping, and make a slow-closing door close slower. On a 1971-era house that's had one or two opener swaps already, the spring is often the one component nobody's touched, and it's usually the first thing to show wear when the temperature drops hard. We check it regardless of what brought us out.
