8 Common Sectional Door Repairs You Can Do Yourself in 2024

Sectional doors, often seen in garages, warehouses, and industrial settings, are popular due to their durability and functionality. However, like any other mechanical system, they are prone to wear and tear over time. While some issues might require professional help, many common repairs can be done by yourself with a bit of know-how and the right tools. Here are eight common sectional door repairs you can tackle on your own in 2024.

1. Fixing a Noisy Door

Identifying the Source of the Noise:
Noisy doors can be a nuisance. Common culprits include loose hardware, worn rollers, and lack of lubrication. Start by inspecting the door’s components to pinpoint the source of the noise.


  • Tighten Loose Hardware: Use a socket wrench to tighten any loose bolts or screws on the door and track.
  • Lubricate Moving Parts: Apply a high-quality lubricant specifically designed for garage doors to the rollers, hinges, and tracks.
  • Replace Worn Rollers: If the rollers are worn or damaged, replace them with new ones. Nylon rollers are quieter than metal ones.

2. Replacing Broken Springs

Understanding the Types of Springs:
Sectional doors typically use torsion or extension springs. These springs are under high tension, so safety is paramount.


  • Torsion Springs: If a torsion spring is broken, it’s advisable to replace both springs even if only one is damaged. Carefully unwind the unbroken spring using winding bars, remove the broken spring, and install a new one.
  • Extension Springs: These are easier to replace. Simply detach the broken spring from the door track and support brackets, and attach a new one.

Safety Tip: Always use proper safety gear, and if you’re unsure, consider seeking professional assistance for spring replacement.

3. Realigning the Sensors

Diagnosing Sensor Issues:
If your door won’t close, the problem might be misaligned sensors. Most sectional doors have photo-eye sensors that prevent the door from closing if an object is detected in its path.


  • Clean the Sensors: Dust and dirt can obstruct the sensors. Clean them with a soft cloth.
  • Realign the Sensors: Ensure both sensors are facing each other and are at the same height. Adjust them until the indicator lights are steady.

4. Repairing the Door Track

Identifying Track Problems:
A misaligned or bent track can cause your door to operate improperly or get stuck.


  • Realign the Track: Loosen the screws that secure the track to the frame. Tap the track gently back into position using a rubber mallet, then retighten the screws.
  • Straighten a Bent Track: Use a pair of pliers to straighten minor bends. For more significant damage, you might need to replace the affected section of the track.

5. Replacing Weatherstripping

Signs of Worn Weatherstripping:
Weatherstripping helps keep out drafts, pests, and moisture. If it’s cracked or peeling, it needs replacement.


  • Remove Old Weatherstripping: Pull off the old weatherstripping from the bottom and sides of the door.
  • Install New Weatherstripping: Cut the new weatherstripping to the appropriate length and press it firmly into place. Ensure it creates a good seal when the door is closed.

6. Fixing a Sagging Door

Diagnosing the Sag:
A sagging door can be caused by loose hinges or an unbalanced door.


  • Tighten Loose Hinges: Check all hinges for tightness and tighten any that are loose.
  • Adjust the Door Balance: If the door is still sagging, adjust the spring tension to balance the door. This might involve tightening or loosening the torsion spring.

7. Replacing a Damaged Panel

Assessing Panel Damage:
A damaged panel can affect the door’s operation and appearance. Minor dents can be fixed, but severely damaged panels might need replacement.


  • Remove the Damaged Panel: Unscrew the hinges connecting the damaged panel to the others and slide the panel out of the track.
  • Install the New Panel: Slide the new panel into place and reattach the hinges.

Tip: When replacing a panel, ensure it matches the rest of the door in color and style.

8. Troubleshooting Remote Control Issues

Common Remote Problems:
If your door isn’t responding to the remote, the issue could be as simple as a dead battery or as complex as a malfunctioning receiver.


  • Replace the Batteries: Try replacing the batteries in the remote first.
  • Reprogram the Remote: If new batteries don’t solve the problem, reprogram the remote to the door opener.
  • Check the Antenna: Ensure the opener’s antenna is not damaged and is hanging down correctly.
  • Inspect the Wiring: If none of these steps work, inspect the wiring inside the opener unit. Look for loose connections or signs of damage.


Maintaining your sectional door and performing minor repairs yourself can save you time and money. However, always prioritize safety, especially when dealing with high-tension components like springs. With these common repairs, you can keep your sectional door in top working condition throughout 2024 and beyond. Regular maintenance and timely repairs will extend the life of your door and ensure it operates smoothly and quietly.
