Florissant, MO · Garage Door Service
Florissant homes built in the 1960s and 70s are hitting the age where torsion springs fail. Here's why, what it costs, and what to check before you call.
Most of the houses we get called to in Florissant went up between 1947 and 2011, but the bulk of the stock clusters in the 1960s and 70s, with a median build year around 1963. That matters for one reason: torsion springs have a service life measured in cycles, not years, and a spring installed when a house was built in the Eisenhower or Nixon era is long past due, even if nobody's touched it since.
The cold winters here add to the wear. Steel contracts in cold weather, and a spring that's already fatigued from thirty-plus years of daily cycling gets less forgiving right when the temperature drops. We see the same pattern across the 45 named areas that make up this side of the county - older torsion springs, original hardware, and a cold snap that finishes the job gravity and metal fatigue already started.
This isn't a design flaw in the door. It's just math. A spring rated for roughly 10,000 cycles hits that number faster in a house that's been opening and closing a door twice a day for five decades than one built last year. If your house falls in that mid-century wave, the spring is not a question of if, but when.
I can't hand you a number here without a real quote in hand - too much depends on spring size, door weight, and whether it's a single or double torsion setup. What I can tell you is what drives the cost up or down.
A single spring on a lighter door is a smaller job than a double-spring setup on a heavier insulated door, and Florissant has plenty of both, depending on when the house was built and what door came with it. If the cable or drum shows wear from the same age and cold-weather stress that killed the spring, that adds to the job - we're not going to replace a spring and leave a frayed cable to snap in a month.
Household income across the service area runs a median of $84,942, and most homeowners we talk to want a straight answer before we touch anything, not a surprise on the invoice. That's the right instinct. Ask for the number before the truck rolls, and ask what's included - spring only, or spring plus a hardware check.
The classic sign is a door that feels twice as heavy as it used to, especially if you've ever lifted it by hand with the opener disconnected. A torsion spring on its way out often gives you a loud bang first - that's the spring itself snapping, not something breaking downstream - and afterward the door won't stay up on its own or the opener strains and stalls partway through the cycle.
Cold mornings make it worse. If the door works fine in the afternoon but groans, jerks, or refuses to open on a cold January morning, that's consistent with a spring that's already fatigued and losing what little flex it has left in low temperatures. You might also notice one side of the door hangs lower than the other - a sign of a broken spring on a double-spring setup where the second spring is still carrying the whole load.
Don't ignore a gap forming between the panel and the track, or cables that look loose and slack instead of taut. Those are downstream symptoms of the same root cause and they get worse, not better, on their own.
I'll say this plainly: don't replace a torsion spring yourself. It's wound under enough tension to break a bone or worse if it slips off a winding bar, and that's true regardless of how many videos make it look simple. This is one of the few jobs in this trade where I'd rather lose the work than see someone hurt themselves saving on labor.
What you can safely do yourself is diagnose. Disconnect the opener using the manual release and try lifting the door by hand - if it feels like dead weight and won't stay up around waist height, the spring is gone or going. You can also look at the spring itself, if it's visible, for a gap in the coil, which means it's already broken.
Beyond that, leave the winding bars in the truck. If your house is one of the many in this area built with original hardware from the 1960s or 70s, the parts and tension specs may not match what's stocked today, and guessing on tension with old, possibly mismatched hardware is a bad way to spend an afternoon.
Cold makes steel less flexible, and a torsion spring that's already fatigued from decades of cycling has less give left when the temperature drops. Since much of the housing here was built in the 1960s and 70s, a lot of springs are aging out right around the same time winters here stress them hardest.
Disconnect the opener with the manual release cord and lift the door by hand. If it feels heavy, drops on its own, or won't stay up around waist height, the spring has lost its tension or broken. If it lifts easily and the opener still won't run it, the problem is more likely electrical or in the opener itself.
You can, but it's usually not the smart move. If one spring broke from age and cycling, the second is on the same clock and close behind. Replacing both at once means one visit instead of two, and matched tension on both sides instead of one old spring and one new.
