If you walked into your garage this morning and the door wouldn’t budge, or you heard a loud bang and now nothing works, there’s a good chance your garage door spring broke. It happens to homeowners across Burnaby every single week, especially during the colder months when temperature swings put extra stress on aging hardware.
The short answer to why it broke: springs wear out. Every time your garage door opens and closes, the spring does the heavy lifting. After thousands of cycles, the metal fatigues, and eventually it snaps. It’s not a sign that something was done wrong. It’s just how springs work.
Here’s what you need to know, what’s safe to do right now, and how to get it properly fixed.
Many homeowners first notice this issue while dealing with a larger garage door repair problem.
What Garage Door Springs Actually Do
Most homeowners don’t think about their springs until something goes wrong. But these components are doing serious work every day.
Your garage door weighs anywhere from 150 to 400 pounds depending on size and material. The springs counterbalance that weight, which is what makes it possible for a relatively small motor or a person’s hand to lift the door smoothly. Without functioning springs, the opener is effectively trying to deadlift a car.
There are two main types: torsion springs, which sit horizontally above the door on a metal shaft, and extension springs, which run along the sides of the door and stretch as the door moves. Most modern homes in Burnaby use torsion springs because they’re more durable, more balanced, and safer when they fail.
Why Garage Door Springs Break
Springs don’t last forever. The honest reason most springs break is simply that they’ve reached the end of their service life. But a few factors can speed up that process significantly.
Rust is a major one in the Lower Mainland. Burnaby gets a lot of moisture through the fall and winter months, and when that moisture gets into the metal coils, corrosion forms. Rust weakens the steel and causes the coils to bind instead of moving freely, which puts uneven stress on the spring every time the door cycles.
Temperature changes also play a role. Going from a cold garage overnight to warm afternoon temperatures causes the metal to expand and contract. Over years, this repeated movement accelerates metal fatigue.
Poor or zero maintenance speeds everything up. Springs that have never been lubricated tend to corrode faster, generate friction, and wear down unevenly.
Most Common Causes of Broken Garage Door Springs
Based on what technicians see most often in Burnaby homes, these are the main culprits:
Normal wear and cycle fatigue. The average spring is rated for around 10,000 cycles. If you open and close your garage four times a day, you’ll hit that limit in about seven years. Many homeowners have no idea their springs have an expiration point.
Rust and corrosion. Moisture from rain, condensation, and damp air breaks down the spring coating and causes the coils to rust from the inside out.
Lack of lubrication. Dry springs generate more friction per cycle, which means faster wear on every movement.
Poor installation or wrong spring size. A spring that’s undersized for the door weight will work harder than it should and fail well before its expected lifespan.
Cold weather stress. Metal becomes more brittle in cold temperatures. A spring that’s already worn can snap on the first cold morning of the year when the door has been sitting overnight.
Signs Your Garage Door Spring Is Broken
Sometimes a spring break is impossible to miss. Other times the signs show up before the snap happens.
The door won’t open. This is the most obvious sign. If the opener is running but the door isn’t moving, or it’s only lifting a few inches before the motor struggles and reverses, a broken spring is likely the cause.
A loud bang from the garage. A torsion spring snapping under tension sounds like a gunshot inside an enclosed space. If you heard something like that and now the door won’t operate, that’s almost certainly what happened.
The door looks uneven or crooked. On a two-spring system, if one spring breaks, the door may lift on one side and drag on the other, leaving it visibly tilted.
The cables are loose or hanging. The lift cables and torsion drums work together with the springs. When a spring breaks, the cable can go slack or fall off the drum entirely.
The door feels extremely heavy. If you try the emergency release and attempt to lift manually, a door with a broken spring will feel almost impossible to move. A healthy door should lift with reasonable effort.
What Happens When a Torsion Spring Snaps
A torsion spring stores a significant amount of mechanical energy when wound. When it breaks, that energy releases all at once. In a properly installed system, the spring is contained on the shaft and the break happens with a loud noise but the components stay in place.
The door then becomes completely unsupported by the spring system. The opener, if it continues to run, is now working against the full weight of the door rather than a counterbalanced load. This can burn out the opener motor, damage the drive mechanism, and pull the lift cables off the drums.
It’s important to stop using the door immediately after a spring breaks. Using the opener repeatedly on a broken spring system causes damage well beyond the spring itself.
Can You Open a Garage Door With a Broken Spring?
Technically, yes. Safely, no.
Most people know about the red emergency release cord that disengages the opener and allows manual operation. Pulling that cord will free the door from the automatic mechanism, but without the spring doing its job, the door will be extremely heavy. Lifting it manually requires significant effort, and holding it up while you move a vehicle is genuinely dangerous.
If the door is closed and you need to get a vehicle out in an emergency, get someone to help you lift it manually while another person holds it up. Never go underneath a door that isn’t properly supported.
Better yet, avoid using the door at all until the spring is repaired. Most spring repairs can be completed the same day you call.
Is a Broken Garage Door Spring Dangerous?
Yes, it can be. This isn’t said to alarm anyone, but it’s important to understand the risks clearly.
The spring itself, once broken, has already released its stored tension. The danger after that comes from trying to operate the door. A door that’s lifted by an opener with a failed spring system can drop suddenly and unpredictably if the opener fails or the emergency release is engaged. A 200-pound door falling without warning is a serious injury risk.
Attempting to replace the spring yourself is where the real danger comes in. Winding and tensioning a torsion spring requires specialized winding bars and an understanding of exactly how many turns are required for the spring size and door weight. Applying the wrong tension or losing control during the winding process can result in serious injury. This is not a repair that’s recommended as a DIY project.
What Homeowners Should Do Immediately
As soon as you realize your garage door spring has broken, here’s a practical sequence:
Stop using the opener. Don’t run it repeatedly trying to force the door to move. Disengage it from the door if necessary to prevent motor burnout.
Do not manually lift the door alone. If you absolutely need access, get help and move quickly.
Call a garage door professional. In Burnaby, most reputable companies offer same-day service for broken springs because it’s a safety issue that leaves your home and vehicles inaccessible.
Check your cables while you wait. If you can see the lift cables lying loose on the floor or hanging slack, mention that when you call. The technician will need to address those along with the spring.
DIY vs Professional Garage Door Spring Repair
The internet has plenty of tutorials on replacing garage door springs yourself, and technically, with the right tools and training, it’s possible. But it’s one of those repairs where the risk to reward ratio strongly favors calling a professional.
The tools required (winding bars sized to your spring, the correct replacement spring, cable drums) aren’t things most homeowners have. Buying them for a single repair often costs more than the labour portion of a professional job. And without experience winding the spring to the correct tension, there’s a real chance of getting it wrong in a way that causes the door to be imbalanced, wear out the new spring prematurely, or worse.
A trained technician will also inspect the cables, drums, rollers, and tracks along with a complete garage door maintenance inspection during the repair, catching any secondary wear that you might not notice during a DIY fix. That kind of thorough check-up is part of what you’re paying for.
Types of Garage Door Springs

Understanding the difference helps when talking to a technician or getting a quote.
Torsion springs sit above the door on a horizontal shaft. They wind and unwind to raise and lower the door. Most homes built in the past few decades use this system. They tend to last longer, operate more smoothly, and fail more safely than extension springs.
Extension springs run along the horizontal tracks on either side of the door and stretch outward as the door closes. They’re more common on older doors and lighter doors. When they break, they can snap outward if safety cables aren’t installed, which is a hazard in itself.
High-cycle springs are an upgrade option rated for 25,000 or 50,000 cycles instead of the standard 10,000. For households that use the garage door frequently or as a main entry, high-cycle springs are worth the extra cost.
How Professionals Replace Garage Door Springs
A typical spring replacement takes 45 minutes to an hour and a half depending on the system. Here’s what the process looks like.
The technician will first assess the door, identify the spring type, and check for secondary damage to cables, drums, and hardware. They’ll measure the spring specifications needed: wire diameter, inside diameter, and overall length, which must match the door weight and height precisely.
Once the correct spring is secured, the old spring is safely unwound and removed from the shaft. The new spring is installed and wound to the correct tension using calibrated winding bars. The cables are then checked, re-routed if needed, and the drum tension is verified.
After the spring is in place, the technician will test the door balance manually (it should hold itself up at the midpoint without drifting) and then run the opener through several cycles while checking for smooth, even movement.
If your door also needs cable repair or the opener needs adjustment, those can typically be handled during the same visit.
Garage Door Spring Repair Cost in Burnaby
Spring repair pricing in Burnaby generally falls in the following ranges:
For a single standard torsion spring replacement, expect to pay somewhere between $180 and $280 for parts and labour. If you need both springs replaced (which is recommended and explained below), the total typically runs between $250 and $380. Extension spring replacement tends to be slightly less expensive.
Premium high-cycle springs cost more upfront but can reduce long-term repair frequency. For a busy household that uses the garage as the main entrance, they’re worth considering.
After-hours or emergency service calls will carry an additional fee, usually $50 to $100 above standard pricing. If cables or drums also need repair, those will be added to the total.
Always ask for a written quote before work begins.
How Long Garage Door Springs Last
Standard torsion springs are rated for approximately 10,000 cycles. In practice:
If you open and close your door twice a day, that’s about 13 to 14 years. If you use your garage as the main entry and exit for your home, four to six times a day is common, which brings you to seven years or less. High-cycle springs rated for 25,000 cycles can double or triple that lifespan.
Springs in coastal or high-moisture climates like Metro Vancouver tend to wear faster than the same spring in a dry climate. Regular lubrication and maintenance can meaningfully extend service life.
How to Prevent Garage Door Spring Failure
You can’t make springs last forever, but you can slow down the wear significantly.
Lubricate the springs twice a year. Use a silicone-based lubricant or a spray specifically designed for garage door hardware. Apply it to the coils and wipe off the excess. Don’t use WD-40, which can strip protective coatings rather than protecting them.
Have the door balanced and inspected annually. A professional inspection catches early signs of wear on springs, cables, rollers, and tracks before they become failures. Many companies in Burnaby offer maintenance packages that cover this.
Replace both springs at the same time (see below).
Don’t ignore unusual sounds. Squeaking, grinding, or a door that suddenly feels heavier are all early warning signs worth addressing.
Should Both Springs Be Replaced at the Same Time?
Yes, and here’s why this makes practical sense.
If your garage door uses two torsion springs and one breaks, both springs are approximately the same age and have gone through the same number of cycles. The one that didn’t break is likely only weeks or months away from failing on its own.
Replacing both at once saves a second service call, a second labour charge, and the inconvenience of another breakdown in the near future. Most technicians will recommend this, and it’s sound advice.
Emergency Garage Door Spring Repair in Burnaby
A broken garage door spring isn’t something that can wait several days for repair, especially when the door is stuck closed with your car inside, or stuck open and leaving your home unsecured.
Reputable garage door companies in Burnaby offer emergency repair services, often available evenings and weekends. When calling for emergency service, describe what happened (loud snap, door not moving, visible cable hanging) and whether the door is in the open or closed position so the technician comes prepared with the right parts.
For general garage door repair in Burnaby, emergency cable repair, or opener issues that surface during a spring inspection, a full-service company can handle everything in one visit.
Why Homeowners in Burnaby Trust Professional Garage Door Technicians
There’s a reason emergency garage door calls see quick uptake even when homeowners initially consider DIY. The combination of safety risk, specialized tools, and the need to get it right the first time makes professional repair the practical choice.
A knowledgeable technician brings the right spring specifications, winding tools, and experience with different door systems including residential overhead doors, double doors, commercial roll-up doors, and older extension spring setups common in New Westminster and older Burnaby neighbourhoods.
They’ll also notice things a homeowner might miss: a cable that’s starting to fray, a roller that’s cracked, a track that’s slightly bent. Catching these during a spring repair prevents the next emergency call.
Frequently Asked Questions
Why did my garage door spring break? Garage door springs break because of normal cycle wear, rust and corrosion, lack of lubrication, or extreme temperature fluctuations. Most springs last around 10,000 cycles before they fail.
What causes garage door springs to snap suddenly? Springs snap when the metal fatigue from years of winding and unwinding reaches its limit. Cold temperatures make metal more brittle, which is why many springs snap on cold mornings. Rust weakening the coils from the inside is another common cause of sudden failure.
Is a broken garage door spring dangerous? The broken spring itself is no longer under tension, but operating the door with a failed spring creates a risk of the door dropping suddenly. Replacing the spring yourself is the most significant danger due to the stored energy involved in winding new springs.
Can I open my garage door with a broken spring? You can manually lift the door using the emergency release, but without spring support the door will be very heavy and unsafe to hold up. Avoid using the door until the spring is repaired.
How much does garage door spring repair cost in Burnaby? A single spring replacement in Burnaby typically costs $180 to $280. Replacing both springs runs $250 to $380. Emergency or after-hours calls carry an additional fee.
Should both garage door springs be replaced at the same time? Yes. Both springs age together and reach similar wear levels at the same time. Replacing both prevents a second breakdown shortly after the first.
How long do garage door springs last? Standard springs last roughly 10,000 cycles, which equals seven to fifteen years depending on how frequently the door is used. High-cycle springs rated for 25,000 or more cycles are available for high-traffic households.
Can I replace a garage door spring myself? It’s technically possible but not recommended. Winding a torsion spring under tension without proper tools and experience carries a significant injury risk. The cost savings rarely justify it.
What are the signs of a broken garage door spring? The most common signs are a door that won’t open, a loud bang from the garage, visible slack in the cables, a crooked or uneven door, and a door that feels extremely heavy when lifted manually.
How quickly can emergency spring repair be done in Burnaby? Most Burnaby garage door companies can respond same-day for emergency spring repairs. With the right spring in stock, the actual repair takes under two hours.
Conclusion
A broken garage door spring is one of the most common and disruptive garage problems a Burnaby homeowner can face, but it’s also one of the most straightforward to fix when handled correctly.
