Florissant, MO · Garage Door Service
Florissant homes built mostly in the 1960s and 70s see torsion springs snap hard when cold weather hits, and original door hardware makes replacement harder.
Florissant sits in a cold-moderate climate band, which means the garage doesn't just get cold once a year, it cycles through freeze and thaw over and over from November into March. A torsion spring is a coiled length of steel under constant tension, and steel contracts when it's cold. That contraction adds stress to metal that's already fatigued from years of winding and unwinding every time the door opens.
Most springs are rated for a number of cycles, not a number of years, but age still matters because metal that's been through fifty winters has microscopic wear a five-year-old spring doesn't have. In a house built in the 1960s or 70s, which describes most of the stock around here, the spring on the door may well be original or a decades-old replacement nobody remembers installing. Cold doesn't create the weakness. It finds it. The break usually happens on the coldest morning of the stretch, not gradually, and it happens loud enough that you'll hear it from inside the house.
The mistake we see most is trying to force the door once a spring has gone. If the spring snaps while the door is down, the opener may still try to lift it, straining the motor and the drive gear against dead weight the opener was never sized to move alone. If it snaps while the door is up, the door can drop fast, and there's no spring left to slow it.
The second mistake is spraying the tracks or hinges with a household lubricant and assuming that fixes noise that was actually the spring starting to go. A spring under stress often makes a grinding or creaking sound in the weeks before it breaks, especially in cold weather when the coil is tighter. Lubricant on the rollers won't touch that. If your door has gotten noisy specifically in cold snaps and quiet again once it warms up, that's the spring talking, not the track.
A lot of the houses in this part of the county, Florissant included, were built between 1947 and 2011, with the typical home dating to 1963. That means a torsion spring in an average Florissant garage is working against hardware laid out the way builders did it in the 60s and 70s: single spring on a center bracket, side-mounted, not always the double-spring setup you see in newer construction. When one of those goes, the door has no backup holding it.
The same is true a few miles out. Old Jamestown, Black Jack, and Ferguson all sit within a handful of miles and share that same 1960s-70s building era, so a cold snap that takes out springs in one of these areas tends to take out springs in the others the same week. We don't treat that as a coincidence, it's the housing stock and the weather doing the same thing at the same time across a lot of similar garages.
We're not going to put a number on this page, because a spring job on a 1960s single-spring setup is a different job than a spring job on a newer double-spring door, and the honest number depends on what's actually on your door when we open the panel. What we can tell you is what changes the price: whether it's one spring or two, whether the drums and cables need to come off with it, and whether the bearings show wear from the same age as the spring.
One limitation worth saying plainly: if the spring is original to a house from this era, we're not going to match it with a part off a shelf and call it done. Older torsion hardware sometimes isn't sized the way current springs are, and forcing a modern spring onto old brackets is how you get a second failure a year later. That sometimes means the job takes a little longer or costs a little more than a straight swap would, and we'd rather tell you that up front than surprise you with it.
Steel is stiffest when it's coldest, and overnight is when the garage sits at its lowest temperature of the day. A spring that's already fatigued is most likely to give way right at that point, before the day warms the metal back up even a little. That's why so many of these calls come in before 9am in winter.
If the spring has snapped, don't force the door up or down by hand or with the opener. The door can drop suddenly since the spring isn't there to control its weight. Leave it where it is and call for a repair rather than trying to work around a broken spring yourself.
Age itself doesn't break a spring, but a house from that era is more likely to still have its original torsion hardware, and hardware that old has been through many more freeze-thaw cycles than something installed five years ago. That accumulated stress is what cold weather tends to expose.
