What Causes a Garage Door Spring to Break?

If you own a garage, you know how crucial it is to have a properly functioning garage door. It not only provides security but also convenience. However, garage doors are not immune to issues, and one common problem that many homeowners face is a broken garage door spring. Understanding the causes behind a garage door spring breakage is essential in ensuring its longevity and avoiding unexpected malfunctions. In this article, we will explore the reasons why garage door springs break and provide valuable insights for garage door spring repair and replacement.


A functional garage door is essential for the security and convenience of homeowners. However, garage door springs are prone to breakage due to various factors. In this blog post, we will delve into the causes behind garage door spring breakage and provide valuable insights for repair and maintenance.

Understanding Garage Door Springs:

Garage door springs play a critical role in counterbalancing the weight of the garage door, making it easy to open and close. There are two common types of garage door springs: torsion springs and extension springs. Torsion springs are located above the door, while extension springs are placed alongside the horizontal tracks.

Common Causes of Garage Door Spring Breakage

1. Normal Wear and Tear

Over time, garage door springs undergo continuous cycles of stretching and contracting, leading to wear and tear. Eventually, this wear weakens the springs, making them more susceptible to breakage.

2. Rust and Corrosion

Moisture and humidity can cause garage door springs to rust and corrode. Rust weakens the structural integrity of the springs, increasing the risk of breakage.

3. Poor Maintenance

Lack of regular maintenance, such as lubrication and inspection, can contribute to garage door spring breakage. Neglecting these essential maintenance tasks allows dirt and debris to accumulate, causing friction and premature wear.

4. Improper Spring Installation

Garage door springs should be installed correctly, with the appropriate tension and alignment. Improper installation can lead to excess stress on the springs, leading to breakage.

5. Extreme Temperatures

Extreme temperature fluctuations can affect the performance of garage door springs. Prolonged exposure to high temperatures can cause the springs to weaken, while extreme cold can make them more brittle and prone to snapping.

6. Excessive Weight on the Door

Garage doors are designed to handle a specific weight capacity. Placing excessive weight on the door, such as stacking heavy items, can strain the springs and increase the likelihood of breakage.

7. High Cycle Usage

Garage doors with frequent and excessive usage, such as commercial garages or households with multiple vehicles, experience a higher number of cycles. This increased usage puts additional stress on the springs, reducing their lifespan.

Signs of a Broken Garage Door Spring
A broken garage door spring can exhibit several warning signs. These include:

• The door becomes heavy and difficult to lift manually.

• The door hangs unevenly or appears crooked.

• A loud banging or snapping sound is heard when operating the door.

• The door falls quickly when released from the open position.

If you notice any of these signs, it is essential to refrain from using the garage door and seek professional assistance for inspection and repair.
Garage Door Spring Repair and Replacement
When faced with a broken garage door spring, you have the option of repairing or replacing it. While some individuals may attempt DIY repairs, it is highly recommended to seek professional assistance to ensure safety and proper functionality.

DIY vs. Professional Service

Repairing or replacing a garage door spring involves specific knowledge and skills. Without proper training, DIY attempts can lead to injuries and further damage. Professional garage door service technicians have the expertise and tools required for safe and efficient spring repair or replacement.

Steps for Repairing or Replacing a Garage Door Spring

Repairing or replacing a garage door spring typically involves the following steps:

1. Identifying the type of spring and its specific requirements.

2. Releasing tension from the spring to prevent injury.

3. Removing the broken spring and installing a new one.

4. Balancing and adjusting the spring to ensure proper door operation.

Importance of Regular Maintenance

To extend the lifespan of garage door springs and minimize the risk of breakage, regular maintenance is crucial. Here are some essential maintenance tasks:


Regularly lubricating the springs and other moving parts reduces friction and wear. It is recommended to use a high-quality garage door lubricant for optimal results.

Balancing the Door

Ensuring proper balance of the garage door prevents unnecessary strain on the springs. Imbalanced doors can lead to uneven wear and increased risk of breakage.

Inspecting for Signs of Damage

Regularly inspecting the springs for signs of wear, rust, or damage allows for early detection and timely repair or replacement.

Professional Tune-Up

Scheduling periodic professional garage door tune-ups helps identify potential issues and ensures optimal performance. Experienced technicians can address any concerns and perform necessary adjustments or repairs.

Extending the Lifespan of Garage Door Springs

Taking proactive measures can significantly extend the lifespan of garage door springs. Consider the following tips:


Apply a silicone-based lubricant to the springs every few months to reduce friction and wear.

Balancing the Door

Check the door’s balance periodically and make adjustments if necessary. This ensures even weight distribution and minimizes strain on the springs.

Inspecting for Signs of Damage

Regularly inspect the springs for signs of wear, rust, or damage. Promptly address any issues to prevent further deterioration.

Professional Maintenance

Schedule regular professional maintenance to ensure all components of the garage door system are in optimal condition. Professional technicians can identify potential problems and provide the necessary repairs or replacements.


Garage door spring breakage is a common issue that can disrupt the functioning of your garage door. By understanding the causes behind spring breakage and following proper maintenance practices, you can extend the lifespan of your garage door springs and minimize the risk of unexpected failures. Remember to seek professional assistance for repair and replacement to ensure safety and optimal functionality.

The lifespan of garage door springs varies depending on usage and maintenance. On average, they may need replacement every 7 to 10 years.

It is recommended to replace both springs simultaneously, even if only one has broken. This ensures balanced performance and avoids future issues.

Warning signs of a worn-out garage door spring include difficulty lifting the door, uneven door operation, loud snapping sounds, and a fast-falling door.

The choice between extension springs and torsion springs depends on factors such as the garage door type, size, and personal preferences. Consulting a professional can help determine the best option for your specific needs.

Garage door spring repair can be dangerous and requires specialized knowledge and tools. It is strongly advised to seek professional assistance to ensure safety and proper repairs.
