Garage doors rely heavily on their springs to function properly, but when these critical components break, it can cause inconvenience and safety hazards. Understanding how to fix a broken garage door spring—whether you're considering a DIY repair or professional service—can save time, money, and prevent injuries. This comprehensive guide for Canadian homeowners will walk you through identifying the problem, safety precautions, repair steps, costs, and maintenance tips.

What Types of Garage Door Springs Can Break?

Garage doors typically use two main types of springs: torsion springs and extension springs. Both play a vital role in balancing the door's weight and enabling smooth operation, but they differ in design and placement.

Difference Between Torsion Springs and Extension Springs

Torsion springs are mounted horizontally above the garage door opening, wound tightly under tension. They use torque to control the lifting and lowering of the door. These springs tend to last longer, with an average lifespan of 7-9 years or 10,000 to 15,000 cycles, depending on usage and care.

Extension springs, on the other hand, run along the sides of the door tracks. They stretch and contract to help lift the door. Extension springs often wear out faster than torsion springs and are more prone to snapping if not maintained correctly.

Both types can suffer from wear signs like rust accumulation, visible gaps, or loss of tension, signaling the need for inspection or replacement.

Common Causes of Spring Breakage

Garage door springs endure constant tension and mechanical stress, making them subject to various damaging factors:

Rust Accumulation: Exposure to moisture leads to rust, weakening metal and accelerating breakage. Metal Fatigue: Continuous cycles cause metal fatigue and eventual snap due to thinning or cracking. Improper Maintenance: Lack of lubrication and ignoring minor issues can increase friction and stress on springs.

Regular garage door maintenance and timely inspections can reduce the risk of sudden spring breakage.

What Safety Precautions Should I Take Before Repairing a Broken Garage Door Spring?

Repairing garage door springs, especially torsion springs, involves handling components under extreme tension. Adhering strictly to safety precautions is essential to avoid serious injury.

Wear Protective Gear: Always use safety glasses and gloves to protect your eyes and hands from flying debris or snapped wires. Use Proper Spring Tools: Specialized winding bars and wrenches help safely release and apply spring tension. Avoid makeshift tools. Ensure Garage Door Is Fully Closed: Keep the door secured to prevent unexpected movement during the repair. Understand Spring Tension Risks: Springs store a lot of energy; improper handling can cause them to release violently.

If you feel uncertain or lack the correct equipment, consider professional garage door repair services for your safety.

How Can I Identify That the Garage Door Spring Is Broken?

Recognizing a broken garage door spring quickly helps prevent further damage and ensures timely repair.

Common indicators include:

Door Won’t Open or Close: The garage door may be stuck or difficult to operate due to lost spring tension. Loud Bang Sound: A distinct popping or banging noise often signals a spring has snapped. Door Is Unbalanced: If the door tilts or sits unevenly in the tracks, a broken spring is likely causing uneven force distribution.

For visual inspection:

Look for visible gaps in torsion springs or broken coils. Check extension springs alongside the tracks for any snapped or stretched cables.

Always perform troubleshooting carefully to avoid injury and confirm the exact spring problem before proceeding.

What Tools and Materials Do I Need to Replace a Garage Door Spring?

Successful garage door spring replacement requires specific tools and quality materials for safe and effective repair.

Essential tools include:

Safety glasses and gloves Winding bars (for torsion springs) Adjustable wrenches and pliers Spring replacement kit – specific to your spring type and door model Wire, cable, pulley, and roller replacements if necessary Spring lubricant

Spring replacement kits typically come with the spring(s), cable drums, and necessary hardware. If your garage door shows signs of wear beyond the spring, such as damaged rollers or frayed cables, consider replacing those parts simultaneously to maintain overall door performance.

How Do I Replace a Broken Torsion Spring? (Step-by-Step)

Replacing a torsion spring is a delicate process that should be done with attention to detail and safety.

Step 1: Release Spring Tension Safely

Before removal, use winding bars to slowly unwind any remaining tension. Never substitute tools and ensure a firm grip during this step.

Step 2: Remove Broken Spring

Loosen the set screws on the torsion bar and slide off the broken spring carefully.

Step 3: Install New Spring Using Winding Bars

Position the new spring on the torsion bar and wind it using the winding bars according to the manufacturer’s guidelines.

Step 4: Adjust Spring Tension Correctly

Proper tension is critical for balanced door operation—test the door’s movement and make small adjustments as needed.

Step 5: Lubricate Springs for Longevity

Apply spring lubricant to reduce friction and prevent rust.

Safety Precautions Common Mistakes to Avoid Always use proper winding bars Using screwdrivers or unsafe tools Wear safety glasses and gloves Not wearing protective gear Ensure the door is fully closed Attempting repair with door partially open Double-check tool security Rushing the winding process

Following these steps carefully helps ensure a safer and more durable spring replacement.

How Do I Replace a Broken Extension Spring?

Extension spring replacement is generally less complex but still demands caution.

Step 1: Disconnect the Garage Door Opener

Unplug or turn off the opener to avoid accidental activation during repair.

Step 2: Secure the Door

Clamp or lock the garage door in place to prevent movement.

Step 3: Remove Broken Extension Spring and Cables

Detach the broken spring from the track hanger and safety cables.

Step 4: Install New Spring and Reattach Cables

Attach the new extension spring and secure all cables and pulleys firmly.

Step 5: Test Door Function

Operate the door manually and via the opener to confirm smooth and balanced movement.

Make sure to inspect related parts such as rollers and pulleys during replacement to maintain overall system integrity.

What Is the Typical Cost of Garage Door Spring Replacement?

Understanding repair costs helps in budgeting and deciding between DIY and professional options.

Torsion Spring Replacement Cost: Ranges between CAD 150 to CAD 350 per spring, including labor and parts. Extension Spring Replacement Cost: Generally lower, around CAD 100 to CAD 200. DIY Repair Costs: Primarily involve purchasing spring replacement kits costing from CAD 50 to CAD 150, plus tool investment if not already owned.

Additional factors influencing price:

Emergency call-out fees for after-hours repairs Type and size of garage door springs Complexity of the door system and existing damage

While DIY replacement may save labor costs, risks and safety considerations sometimes justify hiring professionals.

When Should I Call a Professional Garage Door Repair Service?

Certain circumstances make professional garage door repair the safest and most efficient choice:

You lack appropriate tools or experience with spring replacement techniques. The door is off track, excessively heavy, or components beyond springs are damaged. Signs of emergency repair are present, such as door won’t open or sudden spring breakage at inconvenient times. You want assurance of warranty and long-term reliability.

Professional technicians offer expert diagnosis, safer spring installation, and can handle other repairs like cable repair, roller replacement, and track repair. Look for licensed and insured repair services with positive customer reviews to ensure trustworthy work.

How Can I Maintain My Garage Door Springs to Prevent Future Breakage?

Preventive care extends your garage door springs’ lifespan and reduces emergency repairs.

Maintenance tips include:

Routine Inspection: Check springs for rust, deformation, and tension balance regularly. Proper Lubrication: Apply dedicated spring lubricant twice yearly to lower friction and prevent corrosion. Avoid Corrosive Exposure: Keep garage dry and clean to minimize rust formation. Minimize Mechanical Stress: Avoid forcing the door when stuck and schedule prompt repairs for other worn parts.

Consistent maintenance protects your garage door system and ensures smoother operation.
