Types of Garage Door Springs: Extension vs. Torsion Explained
By Master Pro Garage Door | Serving Baltimore, Owings Mills, Pikesville & Surrounding Areas
Understanding garage door spring types Maryland homes use — torsion and extension — helps you know what to expect when one fails and needs replacement.
Your garage door springs are the hardest-working components in the entire system. Every time you open or close your door, the springs bear the full weight — counterbalancing hundreds of pounds so your opener motor doesn’t have to do it alone. When springs fail, the door often becomes impossible to open safely.
Understanding the different types of garage door springs helps you know what’s installed on your door, how long they typically last, and what to expect when it’s time for replacement. This guide covers everything Maryland homeowners need to know about extension springs and torsion springs — the two main types found in residential garage doors.
Why Garage Door Springs Matter
Before diving into types, it helps to understand what springs actually do. A standard two-car garage door weighs between 150 and 400 pounds. Without springs, your opener motor would need to lift that entire weight every time you press the button — which would burn it out quickly and create a serious safety hazard.
Springs solve this by storing mechanical energy when the door closes and releasing it when the door opens, effectively making the door nearly weightless from the opener’s perspective. This is why a door with a broken spring suddenly feels impossibly heavy — the counterbalance is gone.
Because springs are always under extreme tension, they are one of the most dangerous components to inspect or replace without professional training. If you suspect a spring issue on your Maryland home, call (443) 619-7759 before attempting any repairs.
The Two Main Types of Garage Door Springs
1. Extension Springs
Extension springs store energy by stretching — they extend when the door closes and contract when it opens. You’ll find them running horizontally along the sides of the door, parallel to the overhead tracks on each side.
Extension springs are more common in older homes and in garages with low ceilings where there isn’t enough headroom for a torsion spring setup. They’re generally less expensive upfront but require more components and maintenance over time.
Key characteristics of extension springs:
- Located on the sides of the door, running parallel to the horizontal tracks
- Come in pairs — one spring per side
- Require safety cables threaded through them to contain the spring if it breaks
- Also require sheaves (grooved pulley wheels) and cables as part of the system
- More visible and accessible than torsion springs
Extension spring subtypes:
- Open loop: The simplest and easiest to replace. The wire at the end of the spring is open, making it quick to swap out. However, this design is also the most vulnerable — if the loop breaks, the entire spring can come loose.
- Double loop: Stronger than open loop springs because the ends coil around twice before connecting to the pulley and track. More difficult to replace but offer better durability.
- Clipped end: The most durable extension spring type. The ends are clipped directly to the pulley and track bracket, distributing stress more evenly. These last the longest but are the most complex to replace — a job best left to professionals.
Extension spring lifespan: Typically 7–10 years or around 10,000 cycles with average use in a Maryland home.
2. Torsion Springs
Torsion springs are the modern standard for residential garage doors — and for good reason. Instead of stretching, they work by twisting. When your door closes, the spring winds up and stores tension. When you open the door, that tension releases, rotating the torsion bar and lifting the door smoothly and evenly.
You’ll find torsion springs mounted horizontally above the garage door opening, attached to a metal shaft that runs across the width of the door. Most residential doors have one or two torsion springs depending on the door’s weight.
Key characteristics of torsion springs:
- Located above the garage door, centered on the torsion bar
- Heavier doors use two springs; lighter doors typically use one
- Provide smoother, more controlled movement than extension springs
- Last significantly longer than extension springs
- Safer when they break — contained above the door rather than shooting across the garage
- Require more headroom above the door for installation
Torsion spring subtypes:
- Standard torsion: The most common type in Maryland residential homes. Single springs work for lighter doors; heavier doors use two. These mount on the torsion bar above the door and are what most homeowners have.
- Early set: Similar to standard torsion springs but mounted in the middle of the torsion shaft rather than near the drums. They require slightly different hardware but function the same way.
- Steel rolling door: Found primarily in commercial buildings, these springs work with a rolling steel curtain door rather than a traditional sectional door. Rarely seen in residential applications.
- TorqueMaster: A proprietary Wayne Dalton system where the spring is enclosed inside the torsion bar shaft. Because the spring is fully contained, it’s the safest option if it breaks — but it requires specialized tools and expertise to service.
Torsion spring lifespan: Standard torsion springs last approximately 10,000 cycles. High-cycle springs (available as an upgrade) can last 25,000–100,000 cycles — a worthwhile investment for busy Maryland households.
Extension Springs vs. Torsion Springs: Which Is Better?
For most Maryland homeowners, torsion springs are the better choice when it’s time to replace or upgrade:
- Safety: When a torsion spring breaks, it stays on the bar above the door. When an extension spring breaks without a safety cable, it can shoot across the garage at high speed — a serious injury risk.
- Longevity: Torsion springs typically outlast extension springs and offer high-cycle upgrades for heavily-used doors.
- Smoother operation: Torsion springs distribute the door’s weight more evenly, reducing shaking and wear on other components like rollers and tracks.
- Lower long-term maintenance: Extension spring systems have more parts (pulleys, cables, sheaves) that each need monitoring and eventual replacement.
Extension springs remain a practical choice when ceiling height is limited or when budget is the primary concern for an older door that will be replaced soon anyway.
Signs Your Garage Door Springs Need Replacement
Don’t wait for a complete spring failure — watch for these warning signs:
- The door feels unusually heavy when lifted manually
- The door opens unevenly or one side is higher than the other
- You hear loud squeaking, grinding, or a sudden bang (a bang often means a spring just broke)
- The door moves slower than usual or jerks as it opens
- You can see a visible gap in a torsion spring or a stretched/deformed extension spring
- The door reverses immediately after hitting the ground when closing
If you notice any of these signs on your Owings Mills, Pikesville, or Baltimore-area home, call Master Pro Garage Door at (443) 619-7759 before the spring fails completely and leaves you unable to use your garage.
How Long Do Garage Door Springs Last in Maryland?
Maryland’s climate — hot, humid summers and cold winters with significant temperature swings — can accelerate spring wear compared to milder climates. The repeated expansion and contraction of metal in extreme temperatures adds stress to springs over time.
With average use (4 cycles per day), a standard 10,000-cycle spring lasts about 7 years. If your springs are approaching this age or were installed when you moved in and you don’t know their history, a preventative maintenance inspection is a smart investment.
Can I Replace Garage Door Springs Myself?
We strongly advise against DIY spring replacement. Garage door springs are under extreme tension — a torsion spring on a typical residential door stores enough energy to cause severe injury or death if it releases suddenly during installation. This is one of the leading causes of serious garage door injuries among homeowners who attempt DIY repairs.
Professional replacement is fast (usually 1–2 hours), affordable, and eliminates the risk entirely. Our technicians carry springs for all door sizes and types and can complete most replacements same-day throughout the Baltimore metro area.

Frequently Asked Questions
How do I know if I have torsion or extension springs?
Look above your garage door — if you see a horizontal spring (or two) mounted on a metal bar directly above the door opening, those are torsion springs. If you see springs running along the sides of the door parallel to the horizontal tracks, those are extension springs.
How much does garage door spring replacement cost in Maryland?
Spring replacement typically ranges from $150–$350 depending on the spring type, door size, and whether one or two springs need replacing. Torsion springs generally cost slightly more than extension springs due to the specialized tools required. Call (443) 619-7759 for a free quote.
Should I replace both springs at the same time?
Yes — if one spring breaks, we strongly recommend replacing both at the same time. Springs are installed together and wear at the same rate, so if one has failed, the other is likely close behind. Replacing both at once saves you a second service call and keeps the door balanced.
What happens if I use my garage door with a broken spring?
You shouldn’t. A door with a broken spring puts extreme strain on the opener motor (often burning it out), moves unevenly and unpredictably, and can fall suddenly — damaging your car or injuring anyone nearby. If a spring breaks, stop using the door and call a technician immediately.
Are high-cycle springs worth the upgrade?
For most Maryland homeowners who use their garage door 4+ times per day, yes. Standard springs are rated for 10,000 cycles; high-cycle springs go to 25,000 or even 100,000 cycles. The price difference is modest and can save you multiple replacement visits over the life of the door.
