The complete guide to garage door springs covers everything Canadian homeowners need to know about torsion and extension springs, from how they work to how to replace or repair them safely and cost-effectively.
Understanding Garage Door Springs: The Basics
Garage door springs are one of the most essential parts of your garage door system. They do the heavy lifting, quite literally, by counterbalancing the weight of the door so it can open and close smoothly. Whether you’re a DIY homeowner or someone looking for professional garage door spring repair, understanding the different types of springs and how they work is key to keeping your garage door safe and functional.
Why Garage Door Springs Matter
Without properly functioning springs, your garage door opener would struggle to lift the heavy door. Springs make it possible for you to open your garage door with ease, either manually or automatically. They also help prevent the door from slamming shut, which could cause damage or injury.
Types of Garage Door Springs
There are two main types of garage door springs:
- Torsion Springs – Mounted above the garage door opening, these springs twist to generate force and lift the door.
- Extension Springs – Located on either side of the door, these springs stretch and contract to help lift the door.
Each type has its pros and cons, and the choice between them often depends on the size, weight, and design of your garage door. Let’s dive deeper into the key differences between torsion vs extension springs.
Torsion vs Extension Springs: What’s the Difference?
If you’re trying to decide between torsion and extension springs, or you’re just curious about which type your garage door has, here’s a detailed comparison to help you understand the differences and benefits of each.
Torsion Springs
Torsion springs are the most common type used in modern garage doors in Canada. They are mounted horizontally above the door and use torque (twisting force) to lift and lower the door. When the door is closed, the springs are wound tightly. As the door opens, the torsion springs unwind, which helps lift the door.
Advantages of Torsion Springs
- Longer lifespan (15,000 to 20,000 cycles on average)
- Smoother, more controlled movement
- Better balance and less wear on the garage door opener
- Quieter operation
Extension Springs
Extension springs are mounted on either side of the garage door and stretch when the door is closed. As the door opens, the springs contract, helping to lift the door.
Advantages of Extension Springs
- Lower initial cost
- Suitable for smaller garage doors with limited headroom
However, extension springs tend to wear out more quickly and can be more dangerous if they break, especially without a safety cable for extension springs.
Which One Is Better for Canadian Homes?
In most cases, torsion springs are the better choice for Canadian homeowners due to their durability and safety. However, for older homes or garages with limited space above the door, extension springs may be the only viable option. If you’re unsure, it’s best to contact our certified technicians for an assessment.
How to Measure Garage Door Springs Correctly
Knowing how to measure garage door springs is crucial if you’re replacing them yourself or ordering new ones. Using the wrong size can lead to operational issues and safety hazards. Here’s a step-by-step guide on how to measure both torsion and extension springs.
Measuring Torsion Springs
To measure a torsion spring, you’ll need to determine:
- Wire size – Measure 10 or 20 coils and divide by the number of coils to find the wire gauge. For example, 10 coils measuring 2.5 inches equals a 0.250-inch wire size.
- Inside diameter – This is usually stamped on the spring, commonly 1.75” or 2” in residential systems.
- Length of the spring – Measure the spring in its relaxed state (not under tension).
- Wind direction – Look at the direction the spring is wound. Right-wound springs go on the left side of the door, and left-wound springs go on the right.
For reference, consult a garage door spring size and wire gauge chart to ensure you get the correct replacement.
Measuring Extension Springs
For extension springs, you’ll need to measure:
- Spring length – Measure the length of the spring when it’s not stretched.
- Spring diameter – Use a calliper or ruler to measure the diameter.
- Wire gauge – Similar to torsion springs, measure 10 coils and divide the total length by 10.
Always replace both springs at the same time, even if only one is broken, to maintain balance and avoid excessive wear.
Signs of a Broken Garage Door Spring
Garage door springs don’t last forever. Over time, they wear out and eventually break. Knowing the signs of a broken spring can help you avoid injury and further damage to your garage door system.
Common Symptoms
- Garage door won’t open or only opens a few inches
- Loud bang from the garage (spring snapping)
- Visible gap in the spring coil
- Garage door feels unusually heavy
- Uneven door movement or jerking motion
If you notice any of these issues, stop using the door immediately and seek emergency garage door repair services to avoid injury or further damage.
Can You Open a Garage Door with a Broken Spring?
Technically, you might be able to open the door manually, but it’s not recommended. Without the spring to counterbalance the weight, the door can be extremely heavy and dangerous. Attempting to open it could also damage your opener or cause the cables to snap. Instead, book a broken garage door spring repair with a local expert.
Garage Door Spring Lifespan and Maintenance
Like any mechanical component, garage door springs have a limited lifespan. Understanding the expected longevity of your springs and how to maintain them can save you time, money, and hassle in the long run.
Garage Door Spring Lifespan Cycles
The lifespan of a spring is measured in cycles. One cycle equals one full open and close of your garage door. Here’s a general breakdown:
- Standard springs: 10,000 cycles (approx. 7-10 years)
- High-cycle springs: 20,000–50,000 cycles (ideal for frequent use)
If your household uses the garage door as the main entrance, you may go through 3–5 cycles per day. That adds up quickly, so investing in high-cycle springs may be worthwhile.
Tips to Extend Spring Lifespan
- Lubricate springs every 6 months using a silicone-based lubricant
- Schedule regular garage door maintenance to inspect wear and tear
- Ensure proper garage door weatherstripping to reduce moisture and rust
- Keep the door balanced to avoid unnecessary strain
If your door is unbalanced or the springs are under too much stress, you may need a garage door spring tension adjustment.
Adjusting Garage Door Spring Tension
Adjusting the tension of your springs can help fix an unbalanced door or one that won’t stay open. However, this is a risky task and should only be done by experienced DIYers or professionals. If you’re unsure, contact our garage door repair experts to safely adjust the tension.
Improper adjustments can lead to snapped springs or even serious injury. It’s always safer to trust a professional when it comes to spring tension work.
What Happens If You Don’t Replace Old Springs?
Old or worn-out springs can cause:
- Sudden spring failure
- Damage to your garage door opener
- Increased wear on cables and rollers
- Safety hazards for your family and pets
Don’t wait for a complete failure. If your springs are more than 7 years old or showing signs of wear, consider a garage door spring replacement before they break.
Garage Door Spring Replacement Cost in Canada
Wondering how much it costs to replace your springs? The price can vary depending on the type of spring, the size of your door, and labour rates in your area.
Average Cost Breakdown
- Torsion spring replacement: $200–$400 (including parts and labour)
- Extension spring replacement: $150–$300
Keep in mind that these are average prices across Canada. If your door is oversized or custom, prices may be higher. It’s also worth noting that replacing both springs at once is usually recommended and may offer better value.

In the next section, we’ll dive deeper into safety considerations, the role of cables, and whether to DIY or hire a pro for garage door spring repairs.
Safety Considerations When Dealing with Garage Door Springs
Garage door springs operate under high tension, and even a small mistake can lead to serious injury. Whether you’re attempting a DIY repair or simply inspecting your system, safety must always come first. Understanding the risks and taking the proper precautions can help protect your home, your family, and your investment.
Why Garage Door Springs Are Dangerous
When a spring breaks or is improperly handled, it can snap with enough force to cause severe injuries or property damage. Torsion springs, in particular, store a large amount of energy and can whip around violently if released suddenly. Extension springs can also be hazardous if they break without a safety cable for extension springs installed, as they can fly across the garage at high speeds.
Key Safety Tips for Homeowners
- Do not attempt spring replacement without proper tools and training
- Always disconnect the garage door opener before working on the door
- Use locking pliers to secure the torsion shaft when working on torsion springs
- Wear safety goggles and gloves to protect yourself from sudden movements
- Ensure all people and pets are out of the garage during repairs
If you’re unsure or uncomfortable handling springs, it’s best to leave the job to a professional. Garage door spring repair is one of the most dangerous DIY tasks you can attempt, and the risks often outweigh the savings.
When to Call a Professional
There are several scenarios where it’s safer and more practical to hire a professional:
- You’re unsure how to measure or identify your spring type
- The spring has snapped or shows signs of severe wear
- You need a cable repair alongside spring replacement
- Your door is off-track or unbalanced
- You want to upgrade to high-cycle springs or convert from extension to torsion
Our certified technicians at Priority Garage Doors are trained to handle all types of spring repairs safely and efficiently, ensuring your garage door operates smoothly and securely.
Understanding the Role of Cables and Other Components
While springs do the heavy lifting, they don’t work alone. Cables, pulleys, drums, and other components are essential to the overall functionality of your garage door. Knowing how these parts interact can help you spot issues early and keep your door running efficiently.
Garage Door Cables
Cables are attached to the bottom brackets of your garage door and work with the springs to raise and lower the door. When a spring is under tension, the cables help transfer that energy to the door. If a cable frays or breaks, your door can become misaligned or even fall off track.
Common Cable Issues
- Fraying or rusted cables
- Cables slipping off the drum
- Uneven cable tension causing door imbalance
If you notice these problems, it’s best to schedule a garage door cable repair before the issue worsens. Replacing cables is much more affordable than repairing a damaged door or opener.
Pulleys and Drums
In extension spring systems, pulleys guide the cables and help distribute tension. In torsion spring setups, drums are mounted at each end of the torsion bar and help wind and unwind the cables. If these components wear out or become misaligned, they can cause jerky door movement or uneven lifting.
Bearings and End Plates
Bearings reduce friction and allow the torsion shaft to spin smoothly. End plates support the shaft and keep everything aligned. If these parts are worn or damaged, they can create noisy operation and add strain to the springs and opener.
Regular Maintenance Tips
- Inspect and lubricate all moving parts every 6 months
- Check cable condition and drum alignment regularly
- Look for signs of rust, wear, or misalignment
Our garage door maintenance services include a full inspection of your spring and cable system, helping you catch issues early and avoid costly repairs.
DIY vs. Professional Garage Door Spring Repair

Upgrading or Replacing Your Garage Door System
Sometimes, spring issues are just one part of a larger problem. If your garage door is outdated, damaged, or no longer functioning efficiently, it might be time to consider a full system upgrade. Replacing the door along with the spring system can improve performance, safety, and curb appeal.
When Is It Time for a Full Replacement?
Consider a garage door replacement if:
- Your door is over 15–20 years old
- Multiple components are failing (springs, cables, opener, etc.)
- You want to upgrade to a better insulated or modern look
- The door is dented, cracked, or sagging
Upgrading your garage door also gives you the opportunity to install high-cycle springs, improve weather sealing, and enhance energy efficiency with proper garage door weatherstripping.
Spring Considerations During Installation

Choosing the Right Garage Door Spring for Your Home
Not all garage doors are created equal, and choosing the right spring system is critical for long-term performance. Here are some key factors to consider when selecting springs for your garage door in Canada.
Door Size and Weight
Larger, heavier doors require stronger springs. Double-car garage doors, wood doors, and insulated models typically need torsion springs with a higher torque rating. Lighter doors may be compatible with extension springs, but torsion systems are still preferred for their safety and durability.
Spring Cycle Rating
As mentioned earlier, spring lifespan is measured in cycles. If your household uses the garage door frequently, opt for high-cycle springs (20,000+ cycles) to avoid frequent replacements.
Climate and Corrosion Resistance
Canadian winters can be harsh on metal components. Look for springs with protective coatings or galvanized finishes to resist rust and corrosion. Regular lubrication and proper maintenance also go a long way in extending lifespan.
