Garage Door Springs Replacement From Apex Overhead Door
If your garage door won’t lift or you heard a loud bang, the spring may be broken. We replace springs safely and restore proper balance.
Garage Door Spring Replacement
If you heard a loud bang from the garage and now the door won’t open—or suddenly feels extremely heavy—you’re most likely dealing with a broken spring. This is one of the most common failure points in a garage door system, and it usually happens without much warning.
If that’s what you’re dealing with, call Apex Overhead Door at (215) 942-2739 and we’ll take a look right away.
Why Garage Door Springs Fail Even When The Door Seemed Fine
Garage Door Springs Don’t Break Randomly.
They are designed to handle a specific number of cycles—usually around 10,000 open-and-close movements. Every time the garage door operates, the spring moves one step closer to failure. Our technicians observe this progression when a door still works, but begins to feel heavier or less responsive over time. Early warning signs often include rhythmic popping, squeaking, or an opener that sounds like it’s laboring to lift the door.
The mechanical reality is that the steel inside the spring begins to fatigue. Over time, the coils lose flexibility, become brittle, and eventually fracture under tension. This is often referred to as a torsion spring fracture. If you look at the spring above your door and see a 2-inch gap where the steel coils have pulled apart, your spring is 100% snapped. When it breaks, it doesn’t gradually fail—it snaps. And when that happens, the entire system instantly loses its ability to support the weight of the door.

What Actually Changes When A Spring Breaks
The spring is what makes the door feel manageable. Without it, the system shifts immediately from balanced movement to full dead weight.
Loss of counterbalance
Torsion springs above the door or extension springs along the tracks are responsible for offsetting the door’s weight. Once one breaks, that balance disappears instantly. This is typically when homeowners notice the door won’t lift more than a few inches or feels impossible to move manually, that is a safety feature. The garage door opener is only designed to guide a balanced door—not lift a dead-weight door.
Uneven movement and double tension
In a two-spring system, one spring often breaks while the other remains intact. What happens next is critical—the remaining spring is now carrying nearly double the load. That added tension creates uneven lift across the door. The system may still move slightly, but it becomes unstable. Once this starts, it rarely stabilizes on its own and becomes a safety risk. If your door has suddenly become heavy or uneven, call (215) 942-2739 and we’ll confirm whether the spring has failed and what needs to be replaced.
Sudden system strain
When the spring breaks, the opener continues trying to operate as if nothing changed. That’s when internal components begin to fail. The nylon drive gear can strip while the motor continues running without actually lifting the door. This is one of the most common secondary failures after a spring breaks.
Where Things Get Worse After A Spring Breaks
A Broken Spring Doesn’t Stay Isolated—It Triggers A Chain Reaction Across The System.
Technicians observe this when the opener continues to run while the door struggles to move. What happens next is internal damage inside the opener, often leading to motor failure. There’s also structural stress on the door itself. Without proper support, the opener pulls directly against the top section.
Over time, that can bend the panel or tear the mounting point out completely. The cable system is also affected. Once the spring loses its lifting force, the cables go slack and may appear loose or uneven along the sides of the door. What happens next is the cable can jump off the drum, causing the door to hang crooked or jam in place instantly.
Why Spring Replacement Isn’t Something To Experiment With
Garage Door Springs Operate Under Extreme Tension, And That Tension Is What Allows The System To Function.
DIY attempts often fail when homeowners use makeshift tools like screwdrivers instead of proper winding bars, or fail to account for the direction of the wind. This can lead to winding bar kickback, where the stored energy in the spring releases suddenly. The winding cones, shaft, and set screws all have to be controlled precisely during adjustment. This is one of those problems that looks mechanical but behaves unpredictably once tension is involved.
Once that energy releases, it happens instantly—and it’s not something you can react to in time. This is why spring replacement is one of the most controlled and precise parts of the system to work on. We prioritize broken spring calls because we know you have a schedule to keep. We carry all standard spring sizes on our trucks to get your door open and your car out in a single visit.

What Tends To Happen If Replacement Is Delayed
Once A Spring Breaks, The System Doesn’t Stabilize—It Continues To Degrade.
Technicians observe this when homeowners try to keep using the opener to force the door open. What happens next is internal gear stripping or full motor burnout. In most garages, the next failure point is either the opener or the door itself. Continued force on an unsupported system can lead to bent panels, damaged mounting points, or further imbalance. There’s also the safety factor. Without spring tension, the door can drop quickly if moved or released. This is one of those problems that looks manageable until the door moves unexpectedly.
The Moment Homeowners Realize The Spring Has Failed
There’s usually a very clear trigger. This is one of those problems that looks confusing at first—until the pattern becomes obvious. A loud bang, followed by a door that won’t open or suddenly feels extremely heavy. Another common situation is when the car is trapped inside the garage and the door won’t lift at all. What happens next is urgency, because the system is no longer usable. If you’re in that situation, call (215) 942-2739 and we’ll get the spring replaced and the system working again.
If your family uses the garage door as the main entrance, 10,000 cycles can disappear in just 5 years. Ask us about our 25,000 or 50,000-cycle springs—they are made from higher-grade steel and can last 2 to 3 times longer for a fraction more in cost. For families in towns like Langhorne or Bensalem who use their garage as the front door, the 10,000-cycle spring is a 3-year fix. The high-cycle spring is a 10-year fix. That’s a huge value add.
Common Questions About Garage Door Spring Replacement
How do we know if the spring is broken?
A visible gap in the spring coil or a sudden loss of lifting ability usually indicates a break.
Why does the door feel so heavy all of a sudden?
The spring is what offsets the door’s weight. Without it, the full weight is no longer supported.
Can we still use the opener if one spring is broken?
The opener may run, but it’s not designed to lift the full weight of the door and can be damaged quickly.
Do both springs need to be replaced?
In most cases, yes. If one spring has failed, the other is usually near the end of its cycle life.
Is it okay to wait a few days to fix the spring?
We don’t recommend it. Without the spring’s tension, the door is “dead weight.” If someone tries to open it—or if the opener tries to lift it—you can easily cause $400+ in additional damage to the motor gears and the top door panel.
Get the door working safely again
If your garage door won’t open, feels extremely heavy, or you heard a loud snap, there’s a strong chance the spring has failed. We’ve seen exactly how these situations develop and how quickly they turn into larger repairs when they’re left alone. Call Apex Overhead Door at (215) 942-2739 and we’ll replace the spring and restore the balance of the system.
