Commercial Garage Door Spring Repair — Vancouver & Lower Mainland
We replace broken torsion springs on commercial overhead doors across Richmond, Vancouver, Burnaby, Surrey, and the rest of the Lower Mainland. Most jobs are done in under two hours. We carry standard and high-cycle springs on the truck, so there is rarely a parts wait. Call 604-206-5727 any time — including weekends and overnight.
Why Commercial Springs Fail
A standard commercial torsion spring is rated for about 25,000 open-and-close cycles. On a warehouse loading dock that opens 30 times a day, that is under three years of life. Add cold snaps — springs become brittle below 0°C and snap faster in winter — and most commercial springs do not make it to their rated lifespan. The failure is usually sudden: a sharp crack, the door drops, and the opener cannot move the dead weight.
We stock springs by wire diameter, inside diameter, and length. For any door that runs hard daily cycles — courier depots, busy auto shops, food distribution centres — we recommend stepping up to high-cycle springs rated for 100,000 cycles. The cost difference is modest compared to the cost of a service call every two years.
Torsion vs. Extension Springs
Almost all commercial overhead doors use torsion springs mounted on a shaft above the door opening. The shaft runs the full width of the door; one, two, or three springs wind on it depending on door weight. Extension springs — common on residential doors — are rare on commercial doors above 10 feet and essentially nonexistent on industrial-grade sectional doors. If someone quotes you extension springs on a commercial door, ask questions.
Two-spring setups are standard on doors over 10 feet wide or heavier than 200 pounds. When one spring breaks, we replace both. The survivor is at the same wear point and usually fails within weeks. Mismatched spring tension also pulls the door off-track.
Signs Your Commercial Spring Is Failing
- Door feels noticeably heavier when lifted by hand — opener is straining
- One side rises faster than the other or the door tilts as it opens
- Opener runs longer than normal and sounds laboured on the way up
- Door drifts down slowly when held at mid-height — a balanced door holds position
- Visible gap or separation in the spring coil
- You heard a sharp bang from the door area — often described as a rifle shot
What the Repair Involves
We check door balance before touching anything. The opener is disconnected and the door lifted to mid-height by hand. A properly sprung door stays put. From there we pull the spring specs — wire diameter, inside diameter, length, wind direction — confirm against door height and weight, and install the replacement. Most jobs finish in 90 minutes. We run five full cycles before leaving and confirm balance.
Commercial torsion springs are wound under serious tension. Winding bars slip. A spring that unwinds uncontrolled at the wrong moment breaks hands. This is not a maintenance task — it is a job for someone who does it every week.

Frequently Asked Questions
How long does a commercial spring repair take?
Most commercial torsion spring replacements take 90 minutes to two hours on site. We carry standard and high-cycle springs on the truck, so parts are rarely the delay. Heavier doors with three-spring assemblies or damaged drums may take longer.
How much does commercial garage door spring repair cost in Vancouver?
Commercial spring repairs typically run between $300 and $600 for a single-spring job, depending on spring size and door weight. Multi-spring assemblies on large industrial doors cost more. We quote the job before starting — no surprises.
Can a commercial door operate with a broken spring?
A heavy commercial door with a broken spring should not be run on the opener. The motor is lifting dead weight it was not rated for and will burn out fast. Cables and drums are also under abnormal stress. Disconnect the opener and call for service.
