Stuart, FL
Broken torsion spring on a house built in the 1970s or 80s? Stuart Garage Door Pros fixes spring failures across the Stuart service area, from North River Shores to Hobe Sound.
Warning signs
The door won't lift, or it lifts a few inches and stops. You hear a bang from the garage - a sharp crack, like a gunshot - and after that the door feels like it weighs three hundred pounds because, with the spring gone, it does.
Sometimes it's slower: the opener strains, the chain or belt skips, and the door closes crooked because one spring on a two-spring setup let go while the other is still holding on. Most of the houses we work on in this service area went up between 1969 and 1988, with the median landing around 1983.
That matters here because a torsion spring is rated by cycle count, not by calendar years, and a spring installed when a house was built in the late 70s or early 80s has had four and a half decades to rack up open-close cycles. By the time it breaks, it's usually not a surprise to anyone who's been listening to it groan for the last year.
On older doors you'll sometimes find a single center spring instead of the two-spring torsion setup that's standard now. That single-spring design fails the same way, just with less warning, since there's no second spring to carry the door even partway when it lets go.
Watch-outs
The spring itself is a straightforward swap. Where this job goes sideways is everything bolted next to it. A spring that's been overdue for replacement puts extra strain on the cables, the drums, and the bearing plate at the center of the torsion bar, and on a 40-plus-year-old door those parts have usually never been touched.
Replace the spring alone and you can be back out in six months for a snapped cable. Our climate here is mild temperate - not the brutal freeze-thaw cycling that wrecks hardware up north - so corrosion isn't usually the hidden killer it is elsewhere. What gets these springs instead is straight fatigue from years of cycles, plus humidity working on any hardware that wasn't galvanized or wasn't lubricated.
We see a fair number of torsion setups where the spring is fine-ish but the bearing is dry and grinding, which reads to the homeowner as 'the spring is going bad' when it's really the bearing dragging the whole system down. The other place this goes wrong is mismatched springs.
A lot of doors in this area have had one spring replaced at some point without the other, or a spring swapped for one rated for a lighter door after a panel replacement. Two springs of different wind or wire gauge on the same door never age at the same rate, and that mismatch is what causes the second failure a year or two after the first.
Pricing
We're not going to put a number here that doesn't hold up once we're standing in your garage, because spring jobs vary more than almost any other repair we do.
A single-spring replacement on a lighter door is a different job than replacing a matched pair on a heavier insulated door, and if the cables, drums, or bearing plate need to come out at the same time, that changes the job too.
What we can tell you is what drives the cost: whether it's one spring or two, the wire gauge and wind length needed for your door's weight, and whether anything else on the torsion bar is worn enough to go at the same time. A door that's original to a house built in the early 1980s is more likely to need that second category of work than a door with a spring that's been swapped once already.
One honest limitation: if your opener, track, and panels are all original from the 1970s or 80s and the spring failure is the first of several age-related issues showing up at once, a full door replacement can end up making more financial sense than repair. We'll tell you straight if that's where your door is, instead of patching a spring onto hardware that's on its way out anyway.
Local causes
This isn't a generic garage door problem - it's tied to what's actually sitting in driveways across this service area. With roughly 19,430 owner-occupied houses here and housing stock concentrated in the 1980s and 90s across the twelve communities we work in, a large share of the original torsion springs installed when those homes were built have aged well past their rated cycle count. That's a different failure curve than you'd see in a newer subdivision.
The mild temperate climate here means we're not fighting the ice-and-snow stress that cracks hardware in colder states, so when a spring goes in this area, it's almost always plain fatigue - the spring has simply been wound and unwound more times than it was built for. That's consistent across North River Shores, Sewall's Point, Jensen Beach, Port Salerno, and the rest of the area we cover, because the housing ages and climate pattern don't change much town to town here.
What does change is how long a given spring has been left to run past its service life, which is less about the town and more about whether a door has ever had maintenance. A household income in this area around $63,724 means most owners aren't replacing doors on a whim - they fix what's broken, which is exactly the kind of job this is.
Questions
If the door won't budge even when you disconnect the opener and try lifting it by hand, that points to the spring. A working spring should let you lift a door most of the way yourself. If it feels like dead weight or you heard a loud bang before the trouble started, that's almost always a broken spring, not the opener.
No. A broken spring means the cables and opener are carrying weight they're not built for, and that's how cables snap or the opener motor burns out. Don't run the door on the opener once a spring has gone - disconnect it and call for the repair instead.
Two springs on the same door don't always wear evenly, especially if one was replaced at a different time than the other or they're not matched in wind and wire gauge. The spring under more strain gives out first. We generally recommend replacing both at once so they age together.
We can give you a range once we know whether it's one spring or two and roughly how heavy your door is, but an exact number needs us looking at the torsion bar, cables, and bearing in person. Too many of those parts affect the final job to quote blind.
