There are two kinds of homeowners in this world – those who hear a loud bang in the garage and calmly investigate, and those who assume something has exploded and consider moving to a new house.
If your garage door suddenly refuses to open, feels unusually heavy, or greets you with a dramatic snap that rivals a movie sound effect, chances are the spring has failed. Learning how to repair a garage door spring is useful knowledge – even if, in the end, you decide it’s a job best left to trained technicians.
This guide will walk you through how garage door springs work, what goes wrong, what repair involves, and why calling professionals for Calgary garage door spring repair is often the smartest move you can make.
Understanding How Garage Door Springs Actually Work – And Why They Matter
Garage doors are heavy. Even lightweight modern doors can weigh 130 – 200 pounds, and solid insulated models can easily exceed 300 pounds. The reason you can lift them with one hand (or press a button and let a small motor do the work) is because of spring tension.
There are two primary types of springs:
- Torsion springs – mounted horizontally above the garage door opening
- Extension springs – located along the sides of the door tracks
Torsion springs use torque to counterbalance the door’s weight. As the door closes, the springs wind tightly. When the door opens, they unwind and release energy, lifting the door smoothly.
Extension springs stretch and contract along the tracks, also helping balance the load.
When a spring breaks, the door becomes dead weight. That smooth, effortless motion disappears. And suddenly, you realize just how much work that coil of steel was doing.
Signs Your Garage Door Spring Is Broken
Before diving into repair, it’s important to confirm that the spring is the issue. Common signs include:
- A loud bang from the garage
- The door won’t open, or opens only a few inches
- The door feels extremely heavy when lifted manually
- Visible gap in the torsion spring coil
- Crooked or uneven door movement
Sometimes homeowners assume it’s the opener that failed. In many cases, the opener is perfectly fine – it’s the spring that gave up after thousands of cycles.
And here’s a critical detail: garage door springs are rated for a limited number of open-and-close cycles. When they reach that limit, failure is inevitable.
Can You Repair a Garage Door Spring Yourself?
This is where things get interesting.
Technically, yes – replacing a garage door spring is possible as a DIY project. Practically? It’s one of the most dangerous home repairs you can attempt.
Torsion springs are under extreme tension. Releasing or winding them incorrectly can result in:
- Severe hand and finger injuries
- Broken wrists
- Facial injuries
- Serious property damage
Professional technicians use specialized winding bars and follow precise procedures to control tension safely. Improvised tools – like screwdrivers – are a very bad idea.
Extension springs are slightly less complex but still risky due to stored energy and cable tension.
Understanding how to repair a garage door spring is valuable knowledge. Doing it without experience is a different matter.
The Basic Repair Process – What Actually Happens
To appreciate the complexity, here’s an overview of what a proper torsion spring replacement involves:
- Disconnect the opener and secure the door in place
- Carefully release tension from the broken spring using winding bars
- Remove old hardware and cables
- Install the correct replacement spring – matched to door weight and size
- Wind the spring to the correct number of turns
- Reattach cables and test door balance
- Perform safety inspection and fine adjustments
Notice something? There’s no room for guessing. Even the number of turns must be precise. Too much tension and the door flies upward. Too little and it slams shut.
Professionals don’t just replace the spring. They check:
- Cable wear
- Drum alignment
- Bearing condition
- Track alignment
- Opener force settings
That’s why calling experts for garage door spring repair isn’t just about convenience – it’s about safety and system longevity.
Why Proper Spring Matching Matters
One of the most overlooked aspects of spring repair is choosing the correct spring.
Springs vary by:
- Wire thickness
- Inside diameter
- Length
- Wind direction
Installing the wrong spring can shorten the lifespan of the entire system or strain the opener motor.
Experienced technicians measure the door weight directly to ensure the replacement spring is perfectly calibrated. This is not guesswork – it’s physics.
Companies specializing in garage door spring repair understand regional climate demands as well. Temperature fluctuations can affect metal fatigue and spring performance, so selecting high-quality materials is essential.
The Real Cost of DIY Mistakes
Let’s talk numbers.
A spring replacement by professionals is typically far less expensive than:
- Emergency room visits
- Replacing a burned-out opener motor
- Repairing damaged panels from a misbalanced door
- Fixing bent tracks or snapped cables
Many homeowners start a DIY repair hoping to save money, only to call professionals midway through – after discovering just how much tension is involved.
When trained technicians handle the job, they:
- Bring correct tools
- Carry properly matched springs
- Complete the work efficiently
- Provide warranty coverage
And perhaps most importantly – they leave with all fingers intact.
Maintenance Tips to Extend Spring Life
Even if you don’t plan to replace springs yourself, you can help them last longer:
- Lubricate springs every 6 months with garage door lubricant
- Avoid slamming the door manually
- Test door balance annually
- Schedule professional inspections
A balanced door reduces strain on springs and the opener. If the door doesn’t stay halfway open when disconnected from the motor, it may need adjustment.
Preventative maintenance is far cheaper than emergency repair.
When to Call the Professionals
There are moments when DIY enthusiasm should politely step aside. If you notice:
- A broken torsion spring
- Frayed cables
- Door hanging unevenly
- Repeated opener strain
It’s time to bring in trained specialists.

Final Thoughts – Knowledge Is Power, Safety Is Smarter
Understanding how to repair a garage door spring gives you insight into how your home functions. It helps you identify issues early and communicate clearly with technicians.
But knowledge doesn’t automatically mean you should grab winding bars and climb a ladder.
Garage door springs store enormous mechanical energy. When handled improperly, they don’t give second chances.
If you enjoy learning how things work – fantastic. If you value safety, efficiency, and peace of mind – professional service remains the best path forward.
Sometimes the smartest repair decision is knowing when to step back and let experienced hands do the heavy lifting.
