Most Windsor homeowners don't think about their garage door spring until it fails completely. usually at the worst possible moment. Maybe it's a frigid February morning. Maybe you're already late. The door won't open, you hear a strange bang from the garage the night before, and suddenly you're troubleshooting a broken spring in your driveway instead of getting on with your day.
The spring is arguably the most important mechanical component of your garage door system. It does the actual heavy lifting. counterbalancing a door that can weigh well over 100 kilograms, making it feel light whether you're lifting it manually or letting the opener handle it. When the spring weakens or fails, everything downstream suffers: the opener motor strains, the cables go slack, and the door becomes either dangerous or impossible to use.
Here's the reality for Windsor and LaSalle homeowners: our climate is harder on springs than many people realize. Yes, Windsor has Canada's warmest fall and genuinely hot summers. but winters still bring freezing nights, significant moisture from the Great Lakes corridor, and rapid temperature swings between freeze and thaw. That thermal cycling is tough on metal, and springs that might last 10 to 12 years in a more stable climate may show wear sooner here.
Knowing what to look for can save you from an emergency call and protect the rest of your garage door system in the process. Here are six warning signs to take seriously.
This is often the first sign homeowners notice. the door that used to glide up effortlessly now requires real effort to lift manually. A properly functioning spring should make even a heavy door feel relatively light. When the spring loses tension or partially fails, that weight transfers to the opener motor or to you.
To test this: disconnect your opener by pulling the red emergency release cord. Try lifting the door by hand. It should rise smoothly and stay in place when you let go at waist height. If it feels like lifting dead weight, or drops back down when you release it, the springs need attention. Check our services page to learn what a spring inspection involves.
A torsion spring snapping under tension sounds exactly like a gunshot or a car backfiring. Many Windsor homeowners describe hearing it from inside the house and assuming something had fallen over. When you go to investigate and find nothing obvious. but the door won't work the next morning. a broken spring is almost certainly the cause.
If you've heard this sound recently, stop using the door. Look above the door opening at the torsion spring bar. If you see a clear gap or separation in the coils, the spring has snapped and needs immediate professional replacement.
Many Windsor homes. especially the larger detached houses in South Windsor and the older two-car garages in Walkerville. use two torsion springs, one on each side of the shaft. When one spring fails but the other holds, the door will rise unevenly, tilting to one side or appearing to sag during operation.
This isn't just an aesthetic issue. An uneven door puts lateral stress on the tracks and rollers, and can eventually cause the door to jump off track entirely. which is a much more expensive repair. If your door looks lopsided in motion, don't keep operating it hoping it works itself out. Get in touch with our team to have the springs inspected before the problem compounds.
Take a moment to actually look at your torsion spring. It's mounted horizontally above the door opening. What you're looking for:
- Rust or discolouration. moisture from Windsor's high-humidity environment can corrode springs over time, making the metal brittle and prone to snapping without warning - Gaps in the coil. a visible separation means the spring has already broken - Stretched or elongated coils. a spring that looks stretched out has lost its tension and can't do its job properly
Any of these signs means the spring is either already failed or close to it. Schedule a replacement before it becomes an emergency.
Your garage door opener is not designed to lift the full weight of the door. the spring does that. The opener just guides the movement. When a spring weakens, the opener motor compensates by working much harder than it should. Signs of this include:
- The opener sounds like it's grinding or straining during operation, The door slows significantly partway through the cycle, The opener trips its circuit breaker or stops working entirely
Ignoring a failing spring doesn't just risk the spring. it accelerates wear on the opener motor and can lead to needing both replaced at the same time. For answers to common questions about when to repair versus replace, our FAQ page is a good starting point.
A healthy garage door should lower smoothly and come to a controlled stop at the floor. If your door seems to drop faster than expected, or falls with a thud, the spring is no longer providing adequate resistance during the descent. This is a safety hazard. a door that falls unexpectedly can cause serious injury or damage vehicles parked underneath.
If you've noticed this behaviour, treat it as urgent. Stop using the door until the spring has been inspected.
Standard torsion springs are rated for approximately 10,000 cycles. one cycle being a single open-and-close. For a household using the garage two to four times daily, that translates to roughly 7 to 10 years. If your garage door is the main entry to your home (which is common in Windsor's attached-garage neighbourhoods), those cycles add up faster.
High-cycle springs rated for 25,000 to 50,000 cycles are available and worth considering if you use your garage door heavily. They cost more upfront but last significantly longer and are generally worth it for active households.
Garage door springs are under extreme tension. enough that a snapping spring can shatter a car windshield or cause serious injury. This isn't one of those repairs where watching a YouTube video and buying the part from a hardware store is a reasonable approach. The tools required, the technical precision involved in winding the spring to the correct tension, and the real danger if something goes wrong all point to the same answer: call a professional.
Garage Door Windsor handles spring replacements across Windsor, LaSalle, and Essex County, and our service areas page has more detail on where we work.
Q: If one spring breaks, do I need to replace both? A: On double-spring systems (common on wider garage doors), yes. it's strongly recommended. The remaining spring is the same age and under the same wear, meaning it's likely to fail soon after. Replacing both at once saves a second service call and keeps the door properly balanced.
Q: Can I still use my garage door if I think the spring is failing? A: If the spring has already broken. indicated by a loud bang, a visible gap in the coil, or a door that's extremely heavy. stop using it immediately. Continuing to operate the door with a broken spring risks damaging the opener motor, cables, and tracks.
Q: How much does a spring replacement typically cost in Windsor? A: Costs vary depending on the spring type, door size, and whether one or two springs need replacing. Most homeowners in Ontario pay in the range of $250 to $450 for a full replacement including labour. Getting a proper quote from a licensed local technician is the best way to know what your specific door needs.
