It usually happens at the worst possible time. you hit the button to open your garage door on a Monday morning and nothing happens. Or worse, you hear a loud bang from the garage and discover the door won't budge. In most cases like this in Smithfield homes, the culprit is a broken garage door spring.
Spring failures are among the most common service calls in Johnston County, and they catch homeowners off guard because springs tend to fail suddenly rather than giving much warning. This guide breaks down what you're dealing with, what it costs, and what questions to ask before you call for service.
Understanding which type of spring system your door uses is the first step, because it affects cost, replacement approach, and how long your new springs should last.
Torsion springs are the modern standard. They're mounted horizontally on a metal bar directly above the door opening. When the door closes, the springs wind up and store energy; when it opens, they unwind and do most of the lifting. Torsion springs are more durable, operate more smoothly, and are generally considered safer than the alternative.
Most newer homes in Smithfield. including the new construction going up in communities throughout the area. come standard with torsion spring systems. Torsion springs typically last 8 to 15 years depending on usage and maintenance conditions. In our climate, where humidity can accelerate corrosion on the spring coils, staying on the lower end of that estimate is wise planning.
Extension springs run along the horizontal tracks on either side of the door. They stretch to provide lifting tension. These are more common on older homes and lighter doors, and they cost less upfront. but they come with real trade-offs. Extension springs have a shorter lifespan than torsion springs, and when they break, the spring itself can become a projectile if safety cables aren't in place. Many professionals recommend upgrading to torsion springs when extension springs need replacement, especially on heavier doors.
Historic homes in neighborhoods like Brooklyn, or older ranch-style properties that are common across Smithfield and out toward Selma and Four Oaks, are more likely to still have extension spring systems. If your home was built before the mid-1990s and you've never had a spring replacement, it's worth finding out what type you have.
Let's be direct about pricing, because this is where a lot of confusion happens. Spring replacement costs vary based on spring type, door size, and the number of springs involved.
For most residential single-car doors, expect to pay $150,$350 for a complete spring replacement including parts and labor. Double-car doors with heavier springs run higher. typically $275,$450 or more. Torsion spring systems cost more than extension springs due to the complexity of the installation and the higher-grade components involved.
One pricing point that surprises many homeowners: you should almost always replace both springs at the same time, even if only one has broken. Springs in a pair experience the same wear and tear over the same number of cycles. When one fails, the other is likely close behind. Replacing both at once avoids a second service call within months and ensures the door operates with balanced tension.
For a deeper look at how to think about repair costs and whether labor or parts are driving your bill, our breakdown on smart repair decisions is worth reading before you call around for quotes.
Springs don't always fail without warning. Here's what to watch for:
- The door is heavier than usual. Disconnect your automatic opener and try lifting the door manually. A properly balanced door with good springs should stay open at about waist height without you holding it. If it slams down, the springs are losing tension. - Visible gaps in the torsion spring coil. A fully wound torsion spring should look tightly coiled. A gap in the coils. even a small one. means the spring has broken or is near the end of its life. - Uneven movement. If the door rises on one side faster than the other, one spring may be weaker or already broken. - Loud squeaking or grinding. While some noise is normal, new metallic sounds during operation often indicate spring or hardware wear. Corrosion from our humid summers is a common cause in Johnston County homes.
If you notice any of these signs, reach out to our team before the spring fails completely. Catching a weakened spring before it breaks saves you from a door that's stuck shut. or worse, stuck open. at an inconvenient moment.
Garage door springs are under enormous tension. enough to cause serious injury if they release suddenly during handling. Torsion springs in particular require specialized winding bars and an understanding of exactly how much tension to apply for the specific door weight. An incorrectly tensioned spring puts constant strain on the opener motor and can cause the door to slam unexpectedly.
This isn't the type of repair where the risk-reward calculation favors a YouTube tutorial. It's worth paying for professional installation to get it done safely, correctly tensioned, and with the right spring for your door's weight and size. While you're at it, ask your technician to check the safety systems on your opener. a spring replacement visit is a good time to confirm your auto-reverse and obstruction sensors are functioning properly.
Smithfield Garage Doors handles spring replacements throughout the area, including service calls in Selma, Clayton, Garner, and surrounding Johnston County communities. Our technicians stock common torsion and extension spring sizes on their vehicles so most replacements can be completed in a single visit.

Q: My garage door opened halfway and stopped. Could that be a broken spring?
A: Yes, that's a classic sign. When a spring breaks mid-cycle, the opener motor often doesn't have enough mechanical assist to finish lifting the door's weight and the safety system kicks in to prevent damage. Don't repeatedly try to force the door open. that strains the opener and cables. Call a technician.
Q: How long does a spring replacement appointment take?
A: For a standard torsion spring replacement on a single car door, most experienced technicians complete the job in 45 minutes to an hour and a half. If cables, drums, or other hardware need attention at the same time, plan for a bit more time. It's a same-day repair in the vast majority of cases.
Q: Are there higher-cycle springs that last longer?
A: Yes. Standard residential torsion springs are typically rated for 10,000 cycles. Higher-cycle springs. rated at 25,000 or even 50,000 cycles. are available at a higher upfront cost and make sense for households that use their garage door heavily every day. Given Smithfield's humidity and the effect it has on metal components, investing in a higher-cycle spring with a better corrosion-resistant coating is worth considering if you're planning to stay in your home long-term. Ask your technician what options are available for your specific door.
