The cost of converting a garage door from an extension spring system to a two-spring torsion spring system can vary depending on various factors, including the region, the complexity of the installation, the type and quality of the springs used, and the labor costs of the professionals you hire.

Typically, the cost of converting a garage door from extension springs to torsion springs can range from $600 to $800 or more, including the cost of materials and labor. This estimate may vary, so it’s essential to get multiple quotes to ensure you’re getting a fair price.

Additionally, keep in mind that converting your garage door system from extension springs to torsion springs is a task that requires experience and expertise. It is generally recommended to hire a professional garage door technician to perform the conversion to ensure proper installation and safety.

Please note that these price ranges are based on general estimates, and the actual cost may differ depending on your specific circumstances.

Why choose to convert your extension springs to a torsion spring system?

The choice between a torsion spring and an extension spring for your garage door depends on several factors. Let's compare both types: Torsion Springs: Torsion springs are mounted horizontally above the garage door opening, usually on a metal shaft. They utilize torque to counterbalance the weight of the door. Torsion springs provide smoother and more controlled door movement. They are typically considered safer because they are contained within a metal tube, reducing the risk of accidents if a spring were to break. Torsion springs have a longer lifespan compared to extension springs. They are generally more expensive to install and maintain. Extension Springs: Extension springs are typically installed on either side of the garage door, parallel to the horizontal tracks. They stretch and contract to balance the door's weight. Extension springs are generally less expensive to install and maintain. They are easier to replace compared to torsion springs. Extension springs take up more space in the garage, as they require a larger area for extension. There is a higher risk of accidents if an extension spring breaks, as it can become loose and potentially cause injury or property damage. Ultimately, the better option for your garage door depends on your specific circumstances, including the weight and size of the door, available space in your garage, personal preferences, and budget. It is advisable to consult with a professional garage door technician who can assess your garage door and provide expert advice tailored to your situation.

Common Extension Spring Questions

How do you determine the size and quantity of the springs?

The size of extension springs for a garage door depends on several factors, including the weight and height of the door. To determine the appropriate size, you’ll need to gather some information:

  1. Door Weight: Measure the weight of your garage door using a bathroom scale or consult the door manufacturer’s specifications. This information is crucial in selecting the right extension springs.
  2. Door Height: Measure the height of your garage door. Standard residential garage doors are typically 7 or 8 feet tall, but variations exist. The height also affects the spring size selection.
  3. Number of Springs: Determine whether your garage door requires one or two extension springs. This information is usually based on the door design and manufacturer’s recommendations.

Once you have these measurements, you can consult a spring manufacturer or a garage door professional to obtain the appropriate extension springs for your door. They will consider the door weight, height, and other specifications to recommend the correct spring size, wire diameter, and length for optimal performance and safety.

Choosing the right size and type of springs is crucial to ensure the proper functioning and balance of your garage door. Incorrect springs can result in an imbalanced door, excessive strain on the opener, and potential safety hazards. Therefore, it is best to consult professionals or manufacturers with experience in garage door springs for accurate sizing guidance.

How to open the garage door with a broken extension spring?

If you have a broken extension spring and need to open your garage door, you can follow these steps:

  1. Disconnect the Garage Door Opener: Locate the emergency release cord or lever typically hanging from the opener rail near the top of the door. Pull down on the cord or activate the lever to disconnect the door from the opener. This allows you to manually operate the door.
  2. Secure the Door: Ensure that the garage door is securely closed. If it is partially open, gently lower it to the closed position and engage any locking mechanisms if available.
  3. Locate the Broken Spring: Identify the side with the broken extension spring. You may notice a visibly loose or hanging spring.
  4. Lift the Door Manually: Stand inside the garage facing the door and grip the door handle or any other secure points on the bottom section of the door. Lift the door slowly and steadily, using your leg muscles to provide the necessary force. Be cautious as the door will likely be heavier without the assistance of the spring.
  5. Prop the Door Open: Once the door is fully open, find a sturdy object such as a ladder, wooden block, or cinder block. Carefully position it under the door to support its weight and prevent it from closing unexpectedly.

Remember that operating a garage door with a broken spring can be challenging and physically demanding due to the increased weight of the door. It is always recommended to seek professional assistance to repair or replace the broken spring to ensure proper functioning and safety of your garage door system.

Should you replace your extension spring system?

Determining whether to replace your extension spring system depends on several factors. Here are some considerations:

  1. Age and Condition: If your extension springs are old, worn out, or showing signs of damage (such as cracks, rust, or elongation), it may be necessary to replace them. Springs have a limited lifespan and can weaken over time, affecting their performance and safety.
  2. Safety Concerns: Extension springs can be more dangerous than torsion springs if they break, as they can become loose and potentially cause injury or property damage. If you have concerns about the safety of your extension spring system, it might be advisable to replace it with a torsion spring system.
  3. Door Weight and Balance: Extension springs need to be properly adjusted to balance the weight of the garage door. If you have made changes to your door, such as adding insulation or modifying its structure, the existing extension springs may no longer provide adequate balance. In such cases, it might be necessary to replace the extension spring system with torsion springs.
  4. Personal Preference: Some individuals prefer torsion springs due to their smoother operation, increased safety features, and longer lifespan. If you value these benefits and are willing to invest in a conversion, you may choose to replace your extension spring system with torsion springs.

It is generally recommended to consult with a professional garage door technician who can assess the condition of your existing system, evaluate your specific needs and preferences, and provide expert advice on whether a replacement is necessary or beneficial. They can guide you in making an informed decision based on your unique circumstances.



What is an extension spring?

Extension Spring System: Extension springs are installed on both sides of the garage door, stretching and contracting to balance the door’s weight. They take up more space in the garage and can pose a higher risk of accidents if a spring breaks, as it can become loose. However, extension springs are typically more affordable to install and maintain and are easier to replace.
