What Is Garage Door Spring Repair & Replacement?
Torsion and extension springs are what actually lift the weight of your garage door. Every time the door moves, the springs are doing the heavy work, which means they wear out on a predictable cycle, typically after several thousand open-and-close cycles depending on the door's weight and how often it's used. Garage door spring repair and replacement covers diagnosing worn or broken springs and installing correctly sized, correctly wound replacements. This is one of the more technical jobs in garage door service, since springs are under extreme tension and Windsor, CT's climate swings can accelerate metal fatigue in either direction. A door that suddenly feels heavy to lift manually, or that slams down rather than lowering smoothly, is almost always a spring issue.
Why You Shouldn't Wait
A garage door spring under tension stores a significant amount of energy, and a spring that fails suddenly can release that energy violently. This is not a job for guesswork or DIY attempts, since an improperly handled spring can cause serious injury. Beyond the immediate danger, a broken spring puts the full weight of the door onto the opener motor, which is not designed to lift that weight alone. Continued use in this state commonly burns out the opener within a short period, turning a spring repair into a spring-plus-opener repair. A door with a broken spring should not be opened or closed at all until a technician arrives.
Our Process
Confirm the spring type and size
Torsion and extension springs are sized to match your specific door's weight and dimensions. We measure and confirm the correct specification rather than assuming a standard size fits.
Safely release existing tension
Using proper winding bars and safety procedures, we release any remaining tension in the old spring system before removing it, which is the step that makes this dangerous for untrained hands.
Install correctly matched replacement springs
We install springs rated for your door's exact weight, since undersized springs wear out fast and oversized springs put uneven strain on the opener and cables.
Balance the door
After installation, we adjust spring tension so the door balances properly and stays in place when opened partway, which is the clearest sign the spring system is correctly calibrated.
Full cycle and safety test
We run the door through multiple cycles under the new springs, confirming smooth, even lift and normal opener load before finishing the job.
What to Expect
Most spring replacements in Windsor, CT are completed within 60 to 90 minutes, since it's a job our technicians handle regularly and have the right tools for on the truck. You won't need to do anything except keep the garage clear while the work is happening, given the tension involved. Once new springs are installed, we balance the door by hand, meaning it should stay roughly in place if you lift it partway and let go. That balance test is your best sign that the job was done correctly. We'll also run the opener through several cycles afterward to confirm it's no longer straining, since a properly matched spring should do almost all of the lifting work itself.

Frequently Asked Questions
A fully broken torsion spring usually leaves a visible gap in the coil, and the door won't lift at all, even with the opener. A worn spring tends to show up as a door that feels heavier than normal or that the opener strains against.
That's a classic sign of a failed or significantly weakened spring. Without proper tension, the spring can no longer control the door's descent, so it drops rather than lowering under control. Stop using the door and call for service.
We strongly recommend against it. Torsion springs in particular are wound under extreme tension, and releasing or installing them without the correct winding bars and technique has caused serious injuries. This is genuinely a job for a trained technician.
In most cases, yes. If your door has two torsion springs, they wear at a similar rate, and replacing only the broken one usually means the second follows within months. We'll assess the wear on both and recommend accordingly.
It depends on your door's weight and how many cycles it goes through daily, but most quality springs are rated for a substantial number of open-close cycles, generally translating to several years of typical residential use.
It's typically on the higher end of common repairs because of the specialized tools, safety procedures, and correctly matched hardware required, but it's also one of the most impactful repairs for restoring safe, smooth door operation.
