5 Common Causes of Garage Door Damage and How to Prevent Them

Garage doors are a vital component of our homes, offering security and convenience. However, they can experience malfunctions due to various factors. Understanding these factors and implementing preventive measures can greatly reduce the risk of damage and extend the lifespan of your garage door. This article will highlight five common causes of garage door damage and provide practical tips on how to prevent them.

Key Takeaways

  • Sensor malfunctions are a leading cause of garage door issues and can be prevented by regular inspections and cleanings.
  • Spring wear and tear can result in door failure; routine checks and timely replacement of springs are essential.
  • Misaligned tracks can hinder door movement; maintaining proper alignment through periodic adjustments is crucial.
  • Incorrect opener force settings can cause damage; it’s important to adjust these settings according to the manufacturer’s specifications.
  • DIY repair mistakes can exacerbate problems; seeking professional help for complex repairs can save time and money.

1. Sensor Malfunction

We often overlook the importance of safety sensors in the seamless operation of garage doors. These sensors are crucial in preventing the door from closing on objects or individuals in its path. When sensors malfunction, it can lead to the door opening or closing unexpectedly, posing a risk to safety and property. Sensor issues can manifest in various ways, such as doors reversing without any visible obstruction or failing to respond to commands.

Misalignment and dirt accumulation are common culprits behind sensor malfunctions. Regular maintenance, including cleaning and realignment, is essential to ensure the sensors function correctly.

To address sensor malfunctions, we recommend the following steps:

  • Inspect the sensors for dirt and clean them thoroughly.
  • Check for any signs of damage to the wires or circuits.
  • Ensure the sensors are correctly aligned and facing each other.

If these steps do not resolve the issue, it may be indicative of a more complex problem, such as damaged electrical circuits or incorrect wire connections. In such cases, seeking professional assistance is advisable to prevent further damage or safety hazards.

2. Spring Wear and Tear

In our experience, broken springs are a common cause of garage door malfunctions, often bringing daily routines to an abrupt standstill. Torsion springs, in particular, are under high tension and their failure can pose significant safety risks. It’s crucial to consult a professional technician for repair or replacement, as attempting to fix springs without proper knowledge can lead to serious injury or even death.

When it comes to maintaining the longevity of your garage door springs, several factors must be considered. For instance, additional insulation or multiple coats of paint can reduce the life of torsion springs, especially in highly humid environments like coastal regions where corrosive cracking is more prevalent.

To ensure the safety and proper functioning of your garage door, regular visual inspections are essential. Look for signs of wear or damage such as frayed cables, dents in tracks, or rust on metal components. Always release the tension from the springs before attempting any repairs, using winding bars to carefully unwind the springs.

Lastly, it’s important to avoid common maintenance mistakes that can shorten torsion spring life. For example, applying grease to garage door tracks can cause the wheels to ‘skate’ rather than turn on their bearings. Remember, only bearings, hinges, and spring wire require lubricant.

3. Misaligned Tracks

Misaligned tracks are a common cause of garage door damage. We must ensure that the tracks are properly aligned to facilitate smooth operation. Here are steps to maintain track alignment:

  • Visual inspection: Regularly inspect the tracks for any signs of misalignment, such as gaps between the rollers and track.
  • Clear debris: Keep the tracks free of debris, dirt, or rust that can obstruct movement.
  • Check for damage: Look for bends or dents in the tracks. Minor issues can be addressed with tools, but significant damage may require professional intervention.

Misaligned tracks not only impede the door’s movement but can also lead to uneven wear on other components, increasing the risk of failure.

If you encounter uneven movement or your door operates erratically, it could be due to misaligned tracks. Use a level to check the horizontal and vertical tracks. If realignment is needed and you’re not experienced with such tasks, we recommend consulting a professional to avoid further damage.

4. Opener Force Settings

In our collective experience with garage door systems, we’ve identified that opener force settings are a critical component that often goes overlooked. These settings determine the amount of force with which a garage door opener will pull or push the door. It’s essential to ensure that these settings are correctly adjusted to prevent the door from exerting excessive force, which could lead to injuries or fatalities if someone or a pet becomes trapped.

Modern garage door openers are equipped with safety features that reverse the door’s direction if it encounters significant resistance. This is a vital safety mechanism that should be regularly tested.

To maintain the proper function of your garage door, it’s important to regularly check and adjust the opener’s force settings. Here are some steps to follow:

  • Inspect the chain, belt, or screw drive for signs of wear or dirt build-up and clean or replace as necessary.
  • Listen to the motor for unusual noises, which may indicate damage or the need for re-programming.
  • Secure any loose, disconnected, or frayed wiring connections.

Adjusting the limit setting is also crucial as it controls the extent to which the door opens and closes. An incorrect limit setting can lead to malfunctions. To adjust, locate the limit switch adjustment screw, which may vary in position depending on the brand or model of your door. If the door has issues closing, turn the limit adjustment screw anticlockwise.

5. DIY Repair Mistakes

We often encounter homeowners eager to tackle garage door repairs on their own. While this initiative is commendable, it’s crucial to recognize when a task is beyond one’s skill set. Attempting DIY repairs without the necessary expertise can lead to further damage and, more importantly, personal injury.

It’s essential to understand the risks involved with garage door repairs. The complexity of these systems means that even small mistakes can have significant consequences.

For instance, dealing with high-tension components such as springs can be extremely hazardous. Here are some steps we recommend before considering DIY repairs:

  • Conduct a thorough inspection of the garage door components.
  • Perform simple maintenance tasks like lubricating moving parts.
  • Clean sensors and check for obvious signs of wear or damage.

However, for more complex issues, such as those involving springs or opener mechanisms, professional assistance is not just recommended; it’s a necessity. Not only does this ensure safety, but it also helps maintain the warranty of your garage door system. Below is a list of common problems and our advice:

  1. Broken Springs: Consult a professional.
  2. Noisy Operation: Apply silicone-based lubricant to minimize friction.
  3. Damaged Wires: Seek technician help, especially for complex wiring.

Remember, while the internet is replete with ‘how-to’ guides, they cannot replace the expertise and experience of a qualified technician.


In summary, the proper functioning of garage doors is essential for the security and efficiency of our homes and businesses. This article has highlighted five common causes of garage door damage, ranging from sensor issues to improper closing, and provided insights into preventive maintenance and timely repairs. Understanding these issues and implementing regular inspection and maintenance schedules can significantly reduce the risk of malfunctions and extend the life of garage doors. While some fixes may be within the capability of a diligent homeowner, the complexity of certain problems necessitates professional intervention. It is imperative to prioritize safety and expertise over do-it-yourself attempts when dealing with intricate mechanisms like garage doors. By being proactive and knowledgeable about these common causes and solutions, individuals can ensure the longevity and reliable operation of their garage door systems.
