Wondering, “Why has my up-and-over garage door dropped?” Learn the top reasons for a sagging or uneven garage door and what to do next to prevent further damage.
If you’re wondering, “Why has my up-and-over garage door dropped?” you’re not alone, and the issue deserves immediate attention. A garage door suddenly falling out of alignment or failing to stay in place often points to deeper mechanical problems. Broken tension springs, worn cables, or misaligned tracks can throw off the door’s balance, risking your property and personal safety. Ignoring these early warning signs may lead to further damage and more expensive repairs.
Homeowners turn to Security Door Gate and Fence for professional help. Their team is trained to accurately diagnose and fix up-and-over garage door issues with precision and care. Whether a spring replacement or a full safety check, they provide timely service and long-lasting solutions. If your garage door has dropped or shows signs of instability, contact a trusted expert before the problem escalates.
What Does It Mean When a Garage Door “Drops”?
When homeowners say their garage door has “dropped,” they usually mean it has closed suddenly or won’t stay up when opened. This can feel like a free-fall motion or a slow but steady decline after letting go of the handle or remote button.
Up-and-over garage doors operate using a balanced tension system, typically involving counterbalance springs, lifting cables, and side-mounted tension arms. A properly functioning door should glide smoothly and stay in place when opened. So, when it starts to drop unexpectedly, it signals a deeper mechanical failure.
Common Causes of a Dropped Up-and-Over Garage Door
Let’s examine the most common reasons your garage door may have dropped and how Security Door Gate and Fence addresses each one.
1. Broken or Worn-Out Springs
The springs are the muscle behind your garage door. They’re designed to counterbalance the door’s weight and help it lift easily. Over time, these springs weaken or snap from repeated use, extreme temperatures, or lack of maintenance.
Signs of a spring issue include:
- A loud bang when the door drops
- Difficulty lifting the door manually
- Visible separation or gaps in the spring
At Security Door Gate and Fence, we replace torsion and extension springs with precision-matched parts and safe installation practices, restoring both balance and safety to your system.
2. Cable Failures or Fraying
Cables work alongside springs to hold and guide the door as it opens and closes. When a cable becomes frayed, slips off the drum, or snaps entirely, the door can become unbalanced and drop without warning.
Look out for:
- Frayed strands near the drum or bottom brackets
- Uneven movement on one side
- The door is sitting crooked or slanted
Security Door Gate and Fence technicians are trained to spot cable damage early and replace it before more serious failure occurs. Our service ensures your cables are tensioned and aligned perfectly.
3. Damaged or Bent Tracks
The tracks guide the door’s motion. If bent, blocked, or misaligned, even slightly, they can affect how the door moves. A damaged track can cause the door to stick, grind, or drop on one side.
Common indicators include:
- Squealing or grinding noises
- The door is coming off the track
- A visible bend or gap in the track rail
Security Door Gate and Fence offers expert track realignment and part replacements to ensure your door runs straight and stable, without surprise drops.
4. Locking Mechanism Obstruction
Manual locking mechanisms, common in older up-and-over doors, can get stuck or accidentally engage. If the lock disengages suddenly, it can jam the door partway or cause it to slam.
Watch for:
- Resistance when lifting the door
- Loud clicking or jamming sounds
- A key lock or latch that seems stuck
Our Security Door Gate and Fence team can safely inspect, adjust, or disable problematic locking systems to restore smooth operation.
5. Misaligned or Faulty Tension Arms
Tension arms play a critical role in balancing the door’s motion. When installed incorrectly or loosened by wear and tear, the door may lift unevenly or drop as soon as tension is lost.
Symptoms include:
- One side is rising faster than the other
- The door slamming shut during operation
- Difficulty in manual operation
Security Door, Gate, and Fence professionals carefully adjust tension arms during service calls, recalibrating them for your specific door size and weight.
Safety Risks of a Dropped Garage Door
A garage door that drops is more than an inconvenience, a real safety risk.
Injury Hazard
A falling door can cause serious injury to people or pets in its path.
Property Damage
A sudden impact can damage cars, bikes, or tools stored in the garage.
Worsening Repairs
Using a malfunctioning system can put extra strain on springs, cables, and other components, making repairs more complex and costly.
If your garage door has dropped, avoid touching the system. Contact Security Door Gate and Fence immediately for a safe and accurate inspection.
Temporary Troubleshooting Steps for Homeowners
While it’s best to leave the repairs to the pros, here’s what you can do safely:
Visual Inspection
Look for obvious signs like broken springs, frayed cables, or bent tracks, without touching the parts.
Check the Manual Lock
Make sure no internal lock or latch is stuck in place.
Secure the Door
If the door is stuck open, you may be able to lower it by hand (with assistance) gently. Never force it.
Use the Manual Release
Pulling the emergency release cord can help you close the door safely if you’re confident and the door is light enough.
Then call Security Door Gate and Fence for immediate help. Our technicians can assess the issue safely and provide the proper fix the first time.
Long-Term Repair and Maintenance Solutions
Security Door Gate and Fence doesn’t just fix the problem—we prevent it from happening again. Our services include:
- Annual Safety Inspections: We examine all key parts—springs, tracks, cables, and more—for wear and tear.
- Preventive Part Replacements: If a component is nearing the end of its life, we replace it before failure occurs.
- Custom Tension Calibrations: We fine-tune the door’s balance for smooth, long-lasting performance.

Materials Matter: How Age and Use Affect Door Performance
Even the best-made garage doors wear down over time. Heat, humidity, and frequent use can cause key parts to deteriorate.
- Springs lose elasticity
- Cables become brittle
- Panels warp or misalign
- Metal parts corrode or rust
Security Door Gate and Fence offers complete system assessments and part upgrades to ensure older systems stay safe and functional. We also recommend modern materials that last longer and resist weather-related wear.
FAQ – Homeowner Questions Answered
How do you fix a garage door that keeps reversing?
A new garage door that keeps reversing is often caused by misaligned safety sensors, dirty sensor lenses, or obstructions in the door’s path. Clean the sensor lenses and ensure nothing blocks the door’s movement. If that doesn’t help, check alignment and adjust the sensors to face each other directly.
Why does my garage door go up a few inches, then back down?
If your garage door rises slightly and reverses, it’s likely due to broken springs, a faulty opener, or sensor interference. Damaged torsion or extension springs can prevent the door from lifting properly. You may also need to check the opener’s force settings or inspect for blocked safety sensors.
Why is my up-and-over garage door not closing properly?
An up-and-over garage door may fail to close properly due to worn rollers, broken springs, or sensor misalignment. Rusty tracks or loose cables can also disrupt smooth operation. Begin by inspecting the tracks and lubricating all moving parts. If the issue persists, realign or clean the safety sensors.
How to realign garage door sensors?
To realign garage door sensors, loosen the mounting brackets, then gently adjust the sensors so they face each other perfectly. Use a level to align them horizontally. Once the indicator lights on both sensors are solid, tighten the brackets again. Finally, test the door to confirm smooth, uninterrupted movement.
What does a broken spring on a garage door look like?
A broken garage door spring often appears as a visible gap in the coil or a loose, hanging piece along the torsion bar. When it snaps, you may also hear a loud bang. Other signs include uneven lifting, jerky movements, or a door that feels too heavy to lift manually.
Conclusion
Why has my up-and-over garage door dropped? It’s a question no homeowner wants to ask, but one that signals a real issue with your garage door’s safety and balance.
