A garage door should rise evenly from both sides when opening. If one side lifts faster than the other or the door appears tilted during movement, it often indicates a problem within the spring system. Because garage doors rely on springs to counterbalance hundreds of pounds of weight, even a small imbalance can cause uneven lifting and place extra stress on other components.
This issue should never be ignored, as an unevenly lifting door can strain the opener, loosen cables, and accelerate wear on rollers and tracks. Homeowners rely on experienced professionals they can trust, and Local Garage Doors has built that reputation through 30 years of hands-on industry expertise and consistent 5-star ratings on Yelp, Google, Facebook, and Thumbtack. These reviews reflect a long-standing commitment to dependable service and quality workmanship.
If your garage door begins lifting unevenly or appears crooked during operation, professional service can restore proper balance and safe performance.

Why Garage Doors Should Open Evenly
Garage doors operate using a carefully balanced counterweight system. Springs provide the lifting force while cables and drums distribute that force evenly across both sides of the door. This balance allows the door to open smoothly with minimal effort from the opener motor.
When springs function properly, they balance the door’s weight so it moves smoothly and evenly along the tracks. If one spring weakens or breaks, the lifting force becomes uneven and one side of the door may rise higher than the other. Over time, this imbalance can cause additional strain on the door panels, hinges, and track system, potentially leading to more extensive repairs.
Even small alignment changes can affect how the door travels. When one side of the door receives more lifting force than the other, the door may twist slightly within the tracks. This twisting motion is often the first sign that the spring system is no longer operating correctly.
How Single-Spring Systems Behave
Complete Door Imbalance
In a single-spring system, the entire door depends on one spring for counterbalance. If that spring weakens or breaks, the door loses its primary lifting support.
As a result, the door may feel extremely heavy or struggle to open at all. In many cases, the opener may attempt to lift the door but move unevenly due to the sudden weight imbalance. This can cause the door to jerk or stop midway during operation.
Door Tilts During Operation
Without the proper spring support, cables on each side of the door may begin pulling unevenly. This can cause the door to tilt slightly as it moves along the tracks.
A tilted door places extra pressure on rollers, tracks, and hinges, increasing the risk of further mechanical damage. If left unaddressed, this imbalance can eventually cause rollers to slip out of the track.
Opener Struggles to Lift the Door
Garage door openers are designed to guide movement rather than lift the full weight of the door. When the spring fails, the opener must compensate for the missing counterbalance force.
This can lead to slow movement, unusual noises, or the opener stopping mid-cycle. Continued operation under these conditions can shorten the lifespan of the opener motor and internal gears.
How Two-Spring Systems Fail
One Spring Breaks While the Other Works
Many modern garage doors use a two-spring torsion system. When one spring breaks, the second spring may still provide partial lifting support.
Because of this, the door may still open but appear crooked or uneven during operation. Homeowners sometimes mistake this for a track problem when the real issue lies within the spring system.
Door Lifts Higher on One Side
If one spring fails, the remaining spring may pull more strongly on one side of the shaft. This uneven tension can cause the door to lift slightly higher on one side than the other.
Over time, this imbalance can cause rollers to bind or cables to slip. In severe cases, the door may jam within the tracks during operation.
Gradual Spring Weakening
Sometimes springs do not break suddenly but instead weaken over time. When one spring loses tension faster than the other, the door may begin opening unevenly.
This gradual imbalance often appears as a subtle tilt during movement. Early inspection can prevent the problem from progressing into a complete spring failure.
Why Uneven Door Movement Is Dangerous
Cable Slippage Risk
Uneven lifting can cause lift cables to loosen or slip off the cable drums. If a cable slips completely, the door may become stuck or fall suddenly.
Proper spring balance is essential for maintaining correct cable tension and safe door movement.
Track and Roller Damage
When the door rises unevenly, rollers may press harder against one side of the track. This uneven pressure can bend tracks or wear down rollers faster than normal.
Addressing the issue early can prevent costly hardware repairs and maintain proper alignment.
Increased Opener Strain
A door that opens crooked places additional stress on the opener motor and drive system. Over time, this strain may damage internal components or reduce the opener’s efficiency.
Correcting spring imbalance helps protect the opener and extend its lifespan.
Safety Concerns
Garage doors weigh hundreds of pounds, and uneven lifting can create unpredictable movement. If components fail under uneven stress, the door may drop suddenly.
Professional inspection ensures safe operation and helps prevent unexpected accidents.
How Technicians Diagnose Spring Imbalance
Professional technicians use a careful inspection process to determine whether uneven movement is caused by spring failure. The first step often involves disconnecting the opener and testing the door manually to assess how the door moves without motor assistance.
Technicians inspect torsion springs for visible gaps, fatigue, or uneven tension. They also examine lift cables, drums, rollers, and tracks to ensure that all components are aligned and functioning properly.
If one spring has failed in a two-spring system, technicians typically recommend replacing both springs at the same time. Installing matched springs ensures balanced tension and prevents uneven wear in the future.
Preventative Maintenance Tips
Schedule Routine Garage Door Inspections
Annual inspections allow technicians to detect early signs of spring fatigue before a complete failure occurs. Preventative maintenance helps avoid sudden breakdowns and unexpected repair costs.
Routine service can extend the life of your garage door system and maintain smooth operation.
Lubricate Springs and Moving Parts
Applying garage-door-approved lubricant to springs, rollers, and hinges reduces friction and helps components move smoothly.
Lubrication also helps prevent rust and corrosion, which can weaken metal components over time.
Watch for Changes in Door Movement
If the door begins opening slower, unevenly, or with unusual noise, it may indicate developing spring problems.
Addressing these changes early can prevent major repairs and protect other hardware.
Listen for Loud Spring Noises
A loud snapping or popping sound may indicate that a torsion spring has broken.
If this occurs, the door should not be operated until it is inspected by a professional technician.
When to Call a Professional
Professional service should be scheduled if your garage door begins lifting unevenly, appears tilted during operation, or suddenly feels heavier than normal. Visible gaps in torsion springs, loose cables, or unusual noises are also warning signs that require immediate attention.
A trained technician can safely diagnose spring problems and restore proper balance to the garage door system. Attempting to adjust or replace springs without proper tools can be dangerous because these components operate under significant tension.
Conclusion
If your garage door opens unevenly, the issue is often related to spring imbalance or failure within the counterbalance system. Understanding the differences between single-spring and two-spring failure patterns can help homeowners recognize the warning signs before major damage occurs.
