The housing stock across this service area was mostly built between 1973 and 2012, with the heaviest concentration going up through the 1980s and 90s across the eight areas that make up the local market. That matters because a door and opener installed when a house was built is now anywhere from roughly a decade to four decades old, and springs are rated in cycles, not years - a spring on a house built in the 1980s has likely seen tens of thousands of open-close cycles by now, regardless of how well it was maintained.
The climate here sits in a cold-moderate band, which means winters bring enough temperature swing to stiffen steel and grease, making a spring that's already near the end of its cycle life more likely to let go on a cold morning than a mild one. It's not Northern-tier cold, but the swing is real enough to matter on hardware that's already marginal.
With 6,078 owner-occupied houses among roughly 7,629 households in the area, and a median household income over $97,000, most of what we see is routine wear catching up with original equipment - not storm damage or impact, just thousands of cycles on a 20-to-40-year-old spring or opener finally running out.
