When a Spring Breaks, the Door Stops Working
A garage door spring does the heavy lifting: it counterbalances the door's weight so the opener only has to guide it, not lift it. Most homes built since the 1980s use one or two torsion springs mounted on a shaft above the header, while some older doors around Webster Groves and Kirkwood still run extension springs along the horizontal tracks instead. When a spring snaps, the door usually will not move, and forcing it with the opener can strain the drive gear or bend the track. If you already know your door uses a single torsion spring, the sizing and mounting details for torsion spring replacement differ enough from a two-spring setup that it is worth understanding before you decide what to buy.
Spring failure is rarely random. A standard residential torsion spring is rated for roughly 10,000 open-and-close cycles, and St. Louis works against that number from both directions: humid, 90-degree summer afternoons and single-digit winter mornings both speed up metal fatigue in the coil. Newer subdivisions in Chesterfield and Wildwood often have wider 16-foot double doors, which need springs sized to that specific door's weight and drum size rather than a generic replacement off a shelf. A door that will not open at all becomes an emergency garage door repair fast, especially with a car trapped inside.

Torsion Spring Replacement
We measure the door's weight, track drum size, and cable drum ratio before winding a new torsion spring. A mismatched spring causes hard starts, uneven closing, and early cable wear.
Extension Spring Upgrades
Older extension-spring setups, common on doors installed before the mid-1990s, get replaced with properly rated springs and safety cables that keep a broken spring from becoming a projectile in the garage.
Matched-Pair Replacement
On two-spring doors we replace both sides together, even when only one has failed. A mismatched pair wears unevenly and tends to fail again within months.
Full Diagnostic With Every Call
If the real problem turns out to be a bent track or opener wiring instead of the spring, that falls under general garage door repair rather than a spring swap, and we tell you which one you actually need before quoting anything.
Same-Day Parts and Scheduling
Most spring jobs across west St. Louis County get finished the same day the call comes in, with the spring size and type confirmed before a truck leaves the shop.

Real Reviews From Local Homeowners
"Our spring let go on a Saturday morning and the door wouldn't budge. Someone was out within a few hours with the right spring already on the truck."
"I liked that they explained why both springs needed replacing, not just the one that snapped. No pressure, just a clear reason for it."
Garage Door Spring Questions, Answered
Can I replace the spring on my garage door myself?+
It is possible but genuinely risky: a wound torsion spring holds enough stored tension to cause serious injury if a winding bar slips, and getting the wind count or spring size wrong leaves you with a door that slams shut or won't stay open. Most manufacturers treat this as a two-person job that needs specific winding tools, which is why most homeowners have it done once and leave it to a professional after that.
Can you replace just one spring on a garage door?+
On a single-spring door, yes. On a two-spring door we replace both even if only one broke, because the unbroken spring has usually logged close to the same number of cycles and is near the end of its own life. Replacing only one just means another service call a few months later.
How common is it for a garage door spring to break?+
Given a typical rated life of around 10,000 cycles, a spring on a door used several times a day tends to reach the end of that life within roughly seven to ten years, and St. Louis's wide temperature swings between summer humidity and winter cold tend to shorten that further. It's one of the most frequent reasons for a garage door service call in this area.
Can I still use my garage door if the spring is broken?+
You can usually still open it manually and carefully, using the release cord once the opener is disengaged, but you should not run the opener against a broken spring. Without the spring's counterbalance the opener is lifting the door's full weight on its own, which strains the drive gear and can pull the trolley off the rail.
Is it worth fixing a garage door spring?+
In almost every case, yes, since a broken spring rarely means anything else on the door has failed. Replacing the spring, or the matched pair, restores normal operation without touching the track, opener, or panels, which is usually the least involved fix compared with a bent track or a damaged panel.
What is the average lifespan of a garage door torsion spring?+
Most residential torsion springs are rated for around 10,000 cycles, which works out to roughly seven to ten years on a door used a handful of times a day. A garage that doubles as the main entrance to the house tends to wear through that cycle count faster.
