What Springs Do and Why They Matter
This is what a broken spring looks like — the clear gap in the coils is the fracture.
Your garage door springs are the hardest-working component in the entire system. They counterbalance the full weight of the door — often 150 to 400 pounds — so the opener only needs to guide the door, not lift it. When a spring breaks, the door becomes too heavy to operate safely. The opener strains or stalls, additional components wear prematurely, and the system becomes unsafe.
A broken torsion spring is one of the most common — and most disruptive — garage door failures. You may hear a sharp snap or bang, or find the door suddenly too heavy to lift. This is not a repair to force or "get by" with. It requires careful measurement, the right tools, and precision.
What this means for you: the rest of this page explains the components and the math so you can recognize a failing spring before it leaves you stuck — and so you know what an honest quote looks like when you get one.
Types of Garage Door Springs
Torsion Springs are mounted on a metal shaft above the door opening. They use torque — a twisting force — to lift the door. Most modern residential garage doors use torsion springs because they provide smoother, more controlled movement and last longer than extension springs. These are the springs we work with most often in Sarasota and Manatee Counties.
Extension Springs run along the horizontal tracks on either side of the door. They stretch and contract to lift and lower the door. Extension springs are more common on older or lighter single-car doors. They require safety cables to prevent the spring from becoming a projectile if it breaks.
At Southern Garage Doors, we custom-cut every torsion spring on-site from coil stock carried on the truck. Each spring is measured, cut, and fitted to your door's exact weight and hardware — the way craftsmen used to do it before the industry shifted to one-size-fits-all replacements.
What Spring Replacement Costs
- Single-car spring replacement: $449 (for doors up to 175 lbs) — includes service call, 17-point inspection, custom-cut spring, and 1-year parts warranty.
- Double-car spring replacement: $599 (for doors up to 380 lbs) — includes service call, 17-point inspection, both springs custom-cut, and 1-year parts warranty.
Heavier doors — over 175 lbs single-spring or 380 lbs double-spring — use custom-cut heavy-duty springs. Final price is quoted after on-site weight measurement.
We always replace both springs on a double-car door. When one spring breaks, it tells us both are at the same point in their life cycle. Replacing both prevents a second failure and a second service call.Warning Signs Your Springs Are Failing
Springs don't always break without warning. Watch for these signs:
- The door feels heavier than usual when lifting manually.
- The door opens only partway or the opener strains to lift it.
- Visible gaps or separation in the spring coils — a clear sign of fatigue.
- The door slams shut quickly instead of lowering smoothly.
- Loud bang from the garage — often the sound of a spring snapping.
- The door is crooked or uneven — one spring may have broken while the other holds.
If you notice any of these, stop using the door and call for a professional inspection.
Why DIY Spring Replacement Is Dangerous
Torsion springs are under extreme tension — enough force to lift hundreds of pounds. Attempting to remove, adjust, or install them without proper training and tools can result in serious injury or death.
- Winding bars can slip, releasing stored energy violently.
- Incorrectly sized springs create an unbalanced door that damages the opener and tracks.
- Improper tension can cause the door to fall unexpectedly.
- Without a scale, there is no way to match the spring to the door's actual weight.
This is not a cost-saving repair. A licensed technician with the right tools can complete a spring replacement safely in under an hour. The risk of DIY is not worth the savings.
When to Call a Professional
Call a licensed garage door technician if:
- Your spring has visibly broken or separated.
- The door won't open or feels dangerously heavy.
- You hear grinding, popping, or snapping sounds during operation.
- The door is more than 5 years old and has never been inspected.
- You want to know how much life is left in your current springs.
At Southern Garage Doors, every visit includes a complete 17-point inspection — even if you only called about one spring. We check the entire system so nothing gets missed.
Frequently Asked Questions About Garage Door Springs
Why do garage door torsion springs eventually break?
Over time, every cycle of your garage door — one full up and one full down — bends the spring just a little. Think of it like bending a paper clip back and forth: eventually it fatigues and snaps. The spring is doing the heavy lifting for your door and with each cycle the metal gets a little tired. At that point the spring has simply reached the end of its safe life.
What's a cycle and why does it matter for springs?
A cycle refers to one complete opening and one closing of the garage door. Springs are rated by how many cycles they can perform before fatigue — typically around 10,000 cycles for standard residential torsion springs. When you think about how often you use your door — twice a day, five times a day, or more — you can see how the number adds up.
Why do you always replace both springs?
If your door uses two torsion springs and one breaks, the other has gone through essentially the same number of cycles and is usually very near its limit too. Even if it hasn't snapped yet, it's fatigued. Replacing only one spring means you're leaving yourself another service call soon. It's far more cost-effective and reliable to replace both.
How long do springs last in Sarasota and Manatee Counties?
Because many homes here have heavier hurricane-rated doors and frequent use, springs often last anywhere from about 3 to 12 years, depending on cycles, door weight, and maintenance. Our goal is to install properly rated springs and balance the door so it runs for as long as the materials allow.
What's the difference between standard and high-cycle springs?
Standard residential torsion springs are rated around the 10,000-cycle mark. High-cycle springs are built with thicker wire, more coils, or larger diameter to increase lifespan — some might be rated 20,000 or 30,000 cycles or more. If you use your door very often, or have a heavy door, a high-cycle spring is a smart investment.
Can I replace a garage door spring myself?
We strongly recommend against DIY spring replacement. Torsion springs are under extreme tension and can cause serious injury. A licensed technician with proper tools can complete the job safely in under an hour.
How much does a garage door spring replacement cost?
A single-car spring replacement is $449 (for doors up to 175 lbs) and a double-car is $599 (for doors up to 380 lbs). Both include the service call, a 17-point inspection, and a 1-year parts warranty. Heavier doors use custom-cut heavy-duty springs, quoted on site after weighing the door.
