The first thing that goes on a Westfield garage door isn't the opener, it's the torsion spring. That's true across this whole corner of the state, but here it shows up on a fairly narrow band of houses, because so much of Westfield's housing went up in a tight window. The median home in this area was built in 1965, which puts a lot of garages on original or first-replacement hardware that's now pushing sixty years old.
Springs from that era were sized for lighter, thinner steel doors than what's sold today. Homeowners who've swapped in a heavier insulated door without upsizing the spring end up with a door that slams down instead of settling, or an opener straining on every lift. We see this pattern often enough in the 1965-median housing stock that it's the first thing we check before touching anything else.
Cold makes it worse. This area sits in a cold-severe climate band, and steel torsion springs lose flex as temperatures drop. A spring that's been quietly weakening all summer will often pick the coldest morning of the year to finally let go, usually with a bang loud enough to bring you out in slippers.
