The typical house in Ludlow went up around 1966, right in the middle of the wider area's 1938-1989 build window. A torsion spring wound onto steel is only rated for so many door cycles before it fatigues and snaps, and a lot of Ludlow's original springs have been carrying that same door for close to sixty years. Nobody replaces a spring on a schedule. It gets replaced when it breaks, and in a town where the housing stock is this old, that means a large share of the springs still on these doors are the ones the builder hung. We come out from our Chicopee base, about 6 miles away, so a Ludlow call isn't a special trip, it's a normal one. What we're usually looking at when we get there is a spring that has simply run out of life, sometimes paired with a track or cable that's never been touched either, because on a house this age the spring is rarely the only original part left on the door.
