If you've ever heard a loud bang from your garage. like a gunshot going off. and walked out to find your door completely stuck, you've probably experienced a broken torsion spring. It's one of the most common calls we get at Garage Door Company North Haven, and it happens to homeowners all over town, from the older split-levels along Maple Avenue to the Colonial Revivals tucked back on the larger lots that North Haven is known for.
The good news: spring replacement is a straightforward job for a trained technician. The bad news: it's genuinely dangerous if you try to tackle it yourself.
North Haven sits in a climate zone where winters are legitimately brutal. cold enough to freeze door seals, strain cables, and accelerate metal fatigue in your spring system. The pattern of temperatures dropping below freezing, then climbing back above it multiple times in a single week, is hard on torsion springs. That repeated thermal stress causes the metal to weaken over time, often faster than the spring's rated cycle count would suggest.
Connecticut winters also bring moisture. When that moisture gets into the coils of an unlubricated spring, rust forms, friction increases, and the spring loses tension unevenly. This is why we see so many spring failures in late winter and early spring. right when the cumulative damage from months of cold reaches a breaking point.
If your door has been making grinding or squealing noises during operation, that's worth paying attention to. It's often a sign of metal stress in the spring coils before they give out completely. You can read more about how cold weather specifically affects your system in our post on why North Haven winters are tough on garage doors.
You don't have to wait for the loud snap to know something's wrong. Here are the warning signs to watch for:
If your opener runs but the door barely moves, or if you disconnect the opener and try to lift manually and the door feels like it weighs several hundred pounds, a broken spring is almost certainly the cause. Garage door springs counterbalance the door's weight. without them, most doors are simply too heavy to lift safely.
With the door closed, look up at the horizontal spring mounted above the door opening. If you can see a clear separation or gap in the coils, the spring has snapped. This is a definitive sign. don't try to operate the door until it's repaired.
If one side of your door rises faster than the other, or the door looks crooked when it's partially open, you likely have an extension spring issue on one side, or one of a pair of torsion springs has weakened while the other still holds tension.
When a spring is weakening but hasn't fully broken yet, your opener motor will strain to compensate. If your opener sounds like it's working harder than usual, or it stops partway through lifting and reverses, don't ignore it. Pushing the opener to do the work the spring should be doing will burn out the motor. turning a $200 spring repair into a much more expensive opener replacement job.
Torsion springs are mounted horizontally above the door and use torque to lift it. They're the standard in most modern homes and tend to be more durable, typically rated for 10,000 cycles or more. Extension springs run along the sides of the door track and stretch to help lift the door. They're more common in older garage setups. and given that many North Haven homes were built in the mid-to-late 20th century, you may well have an extension spring system if your door hasn't been updated.
Extension springs tend to have a shorter lifespan and can fail in ways that are harder to spot visually. If your garage was built before 1990 and you've never had the springs replaced, it's worth having a technician take a look.

Spring replacement in Connecticut typically runs between $150 and $350 for a straightforward repair, though the exact cost depends on the spring type, door size, and whether both springs need to be replaced. Technicians will often recommend replacing both springs at the same time. even if only one has snapped. because if one has worn out, the other is likely close behind.
Labor rates in Connecticut generally run $75,$250 per hour depending on the company and timing of the call. Emergency or after-hours service will cost more. The honest advice: if your spring is showing warning signs but hasn't broken yet, scheduling a planned replacement will save you money compared to calling for emergency service on a Saturday morning when your car is trapped inside.
This is worth being direct about. Garage door springs are under extreme tension. a torsion spring stores enough mechanical energy to cause serious injury if it releases suddenly. Without the proper winding bars and technique, you risk broken bones, facial injuries, or worse. A door weighing 150,300 pounds can drop suddenly without spring support.
This isn't a case where being handy makes it safe. It's a job that requires specific tools, training, and experience. Even experienced home improvement folks who are comfortable with most repairs draw the line here. and rightly so. Our post on garage door spring dangers and safety covers the specific risks in more detail if you want the full picture.
For anything spring-related, the right call is to schedule a service visit with a qualified technician.
Q: How long do garage door springs typically last in North Haven? A: Most springs are rated for around 10,000 cycles. one cycle being a full open and close. If you use your garage door four times a day, that works out to roughly seven years. Connecticut's freeze-thaw cycles and humidity can accelerate wear, so real-world lifespan in this climate may be shorter than the rated number suggests. High-cycle springs rated for 25,000+ cycles are available and worth asking about when replacing.
Q: Can I still use my garage door if a spring is broken? A: Technically the opener may still run, but you shouldn't. Operating a door with a broken spring puts extreme strain on the opener motor and cables, risks the door falling suddenly, and can cause additional damage to tracks and rollers. Stop using the door and call a technician.
Q: Should I replace both springs even if only one broke? A: In most cases, yes. If one spring has worn out, the other has been under the same amount of stress and use. Replacing both at the same time costs a bit more upfront but saves you from a second service call. and a second spring failure. in the near future.
