How Do I Know What Garage Door Torsion Spring I Need? 

Choosing the correct garage door torsion springs involves accurate measurements and understanding the specifications of your current springs. Here’s a step-by-step guide to help you determine the right torsion spring for your garage door

Step 1: Measure the Inner Diameter 

The inner diameter (ID) of the torsion spring is crucial for ensuring compatibility with your garage door. Measure the inner diameter or look for markings on the spring indicating the ID. 

Step 2: Determine the Spring Wind 

Garage door torsion springs are either right-hand wound or left-hand wound. Right-hand wound springs coil clockwise, while left-hand wound springs coil counterclockwise. To determine the wind of your spring, look at the winding cone or observe the installation position relative to the anchor bracket. 

Step 3: Measure the Wire Size 

To find the wire size, count 20 coils of the spring and measure their length. Use a torsion spring wire size chart to translate this measurement into the wire size. 

Step 4: Measure the Spring Length 

Measure the overall length of the unwound spring, including any broken torsion spring pieces. Add these lengths together and round up to the nearest whole number.

What is the Purpose of a Torsion Spring on a Garage Door? 

Garage door torsion springs store mechanical energy to assist in lifting and lowering the garage door. They counterbalance the weight of the garage door, making it easier to open manually or with a garage door opener. The torsion springs wind up and unwind as the door opens and closes, respectively, ensuring smooth and controlled movement. 

What Do the Colors Mean on Garage Door Torsion Springs? 

The color coding on garage door torsion springs indicates the wire size, making it easier to identify the right spring during replacement. Each color represents a specific wire size, helping technicians and homeowners select the correct spring for their garage door.

Do Garage Doors Have 1 or 2 Torsion Springs? 

Garage doors can have either one spring or two torsion springs, depending on the door’s size and weight. Single-spring systems are typically found on smaller, lighter doors, while larger, heavier doors often require two springs for balanced operation and increased lifespan. 

Types of Garage Door Springs 

There are several types of garage door springs, each serving a specific purpose: 

  • Torsion Springs: Mounted above the garage door, these springs provide balance by winding and unwinding. 
  • Extension Springs: Located on either side of the door, these springs extend and contract to assist in opening and closing. 
  • TorqueMaster Springs: Encased in a tube, these springs offer a cleaner appearance and added safety features. 

How to Replace Garage Door Torsion Springs 

Replacing garage door torsion springs can be dangerous if not done correctly. Follow these steps to ensure a safe and successful replacement: 

Tools and Parts Required: 

  • Vice grips 
  • Two 3/8″ wrenches 
  • Two 9/16″ wrenches 
  • Torsion spring winding bars 
  • Replacement springs 
  • Tape measure 
  • Step ladder 

Step-by-Step Replacement Guide 

Step 1: Release Tension on the Old Springs 

Using a winding bar, turn the spring in the opposite direction of the winding cone until the tension is fully released. 

Step 2: Remove the Old Springs 

Loosen the bolts attaching the springs to the anchor bracket with two 9/16″ wrenches. Slide the springs to each side of the shaft and remove them. 

Step 3: Remove Torsion Spring Drums and Unhook Cables 

Loosen the set bolts on the torsion spring cable drums and unhook the cables. Slide the drums off the torsion bar and remove the old springs. 

Step 4: Install the New Torsion Springs 

Slide the new springs onto the shaft, ensuring they are on the correct sides (right-wound on the left, left-wound on the right). 

Step 5: Reset Drums and Cables 

Reattach the torsion spring drums and hook the cables back into place. Ensure the cables are taut and even. 

Step 6: Attach New Springs to Anchor Bracket 

Secure the new springs to the anchor bracket using the mounting bolts and tighten them with two 9/16″ wrenches. 

Step 7: Wind the New Springs 

Wind the new springs by turning the shaft in the winding direction. Use the winding bars to achieve the correct number of 1/4 turns for your door height. 

Step 8: Secure the Set Screws 

Once the springs are wound, tighten the set screws to hold the springs in place securely. 

Step 9: Test the Garage Door 

Open and close your garage door several times to ensure it operates smoothly and the springs are correctly installed.

Mountain View Doors sent a competent and professional technician to fix my garage door. I was able to get same day service at a reasonable cost. Tanner (technician) went over everything that he was going to do and asked if I had any questions. The job was completed with high standards. I highly recommend this company.

Tanner came out and revitalized my old garage door, previously known as "the Beast" but now referred to fondly as "the kitten" due to its pleasant purring sound. This was the best money I've ever spent. The visit was affordable, thorough and amazingly helpful. Tanner pointed out all of the positive aspects of my garage door system, of which I thought there were none, and gave very reasonable estimates of work that is likely to be needed in the future. He also gave me great advice on things I can do to protect and maintain the whole system. I could not be happier and I will always call these guys in the future.

From the process of getting the door ordered, to payment, and getting everything done these folks were great. Bram did a great job! Door works way better than my old one, they cleaned everything up, explained maintenance, and they even took the initiative to get better weather stripping and will be coming back to put that in. These days its always great to have a company that just wants to do the job right the first time. Would use them again without a moment of hesitation.

Aaron was quick to respond and was able to schedule the repair for the same day. Bram communicated well on when he would be arriving and thoroughly explained what repair was needed and how much it would cost. Did the repair and included a tune-up on the door making sure all components were working properly. This is the 3rd time I've used Mountain View Doors, all on different properties, and each time they have been expedient, done great work and pricing has been fair and reasonable. Do not hesitate to contact them for all your garage door needs! A+

Tanner did a great job installing two new garage doors for us. He was very friendly and thorough in his explanation of what work he would need to do and what additional options I had with the new doors and system. He took the time to look at some other issues as well to determine if they were something that he could fix. He had the job done pretty quickly, no mess left behind, and took the time to go over all the new features and app to control the doors. Great job overall and very happy with the experience!
