Most houses on Westfield's older streets went up right around 1965, which puts this town squarely in the same build wave as the rest of the service area - but the number that matters is how much of the original hardware never got swapped out. A door installed in 1965 has had roughly sixty winters to work on its spring, its track, and whatever bearing plate the builder used at the time. A lot of that hardware is still hanging there. Nobody replaces a spring until it breaks, and nobody replaces a track until a roller jumps it, so the parts installed the year the house was framed are frequently the parts still doing the job today. That matters more in a cold-climate town like this one: repeated freeze-thaw cycles work bearing points and lubrication harder than a moderate climate would, and hardware sized for 1965 usage doesn't always hold up to sixty winters of it. We come out from Chicopee, about 10 miles away, and what we find on these calls is rarely a random failure - it's metal fatigue that's been building since the Johnson administration.
