Garage door spring repair is the replacement of broken torsion or extension springs that lift the door's weight, typically completed in 60–90 minutes for $220–$380 in London, Ontario.
Same-day service across London, Byron, Masonville, White Oaks, and Hyde Park. Lifetime parts warranty on every spring we install. $95 service-call fee credited to your repair if you proceed.
Most homeowners can confirm a broken spring in under two minutes. If you see any of these, do not operate the door — call us.
A sharp crack — often mistaken for a gunshot or firework. Springs release stored tension violently when they snap.
Opener hums but the door doesn't move, or it lifts a few inches and stops. The opener can't lift 200+ lbs alone.
Look at the spring above the door. A 1–3 inch gap means it's broken. Don't touch — the spring may still hold tension.
Disconnect the opener (red cord) and try lifting manually. A working door lifts easily; a broken spring makes it feel like 200+ lbs.
Snapped or dangling lift cables usually mean the spring failed first. Both need replacement together.
One side higher than the other, or the door tilts. A broken spring on one side throws the whole door out of alignment.
Springs do the actual work of lifting your garage door. The opener motor is rated for only 1/2 horsepower — nowhere near enough to lift a 200-pound door on its own. The springs store mechanical energy when the door closes and release it when the door opens, doing 95% of the lifting work. When a spring fails, the opener strains, the door becomes immovable, and continued operation can damage the cables, panels, and motor.
| Type | Location | Lifespan | Cost (CAD) | Common in |
|---|---|---|---|---|
| Torsion | Above door, on shaft | 15,000–20,000 cycles | $220–$380 | Homes built 2000+ |
| Extension | Alongside tracks | 8,000–10,000 cycles | $180–$260 | Older / lighter doors |
| Heavy-duty torsion | Above door, larger gauge | 25,000–30,000 cycles | $340–$520 | Double doors, commercial |
Torsion springs are safer, quieter, and longer-lasting. When they fail, they typically remain contained on their shaft. Extension springs, by contrast, can launch across a garage when they snap — which is why modern doors include safety cables threaded through them.

Pricing includes the spring itself, labor, the new bearings and cones (when needed), shop materials, and lifetime warranty. A $95 service-call fee covers the diagnostic visit — but if you approve the repair, the $95 is credited to your final bill, so you only pay for parts and labor. The price you approve is the final price.
What drives price up: non-standard spring sizes (custom-cut for unusual doors), commercial high-cycle springs, after-hours emergency rates (a $60 surcharge applies between midnight–6am), and oversized doors over 9 ft wide. What's always free: diagnostic, quote, second-opinion review, and warranty callbacks.
The math looks tempting at first: a torsion spring costs about $40–$60 in parts. A professional installation runs $220–$280. People assume the labor markup is excessive — it's not. The reason is risk. A wound torsion spring carries the same potential energy as a small explosive charge. Improper handling — wrong winding bars, wrong sequence, slipping grip — releases that energy in milliseconds. (Statistics Canada injury data, 2023)
Beyond personal risk: most home insurance policies exclude DIY garage door spring work, and incorrectly sized springs can void your door warranty. The math changes when you count those.
One open-and-close is one cycle. The average London household uses their garage door 4–6 times per day, so a 10,000-cycle spring lasts about 5–7 years. Families who use the garage as a primary entry (8–10 cycles per day) wear springs out in 3–4 years. We always recommend high-cycle springs (20,000+) for active households — the upcharge is small ($60–$90) and they last 2x as long.
Timeline of a typical job: 5 minutes for measurement and confirmation, 10 minutes to safely de-tension and remove the broken spring, 20–40 minutes to install and wind the new spring(s), 10 minutes to balance the door and verify proper operation, 5 minutes for warranty paperwork and walkthrough. We recommend booking a 90-minute window even though most jobs finish in 60.

Spring snapped on Sunday at 8 PM. Texted, got a quote in two minutes, tech showed up by 9:40 PM same night. Fixed in 35 minutes for exactly the price they said.
Got three quotes — one wanted $560, one wanted $420, Garage Door London quoted $310 and showed up in under an hour. Both springs replaced, door is whisper quiet now.
Tech (Marcus) explained exactly what failed and why both springs needed to go. Honest, fast, clean. Gave me a magnet with the warranty info on it. Would call again in a heartbeat.
