Your garage door won't open, and you suspect a spring problem. Before you call for help, understanding whether you have a torsion or extension spring saves you money and prevents unnecessary repairs. Both types lift your door, but they work differently, fail differently, and cost differently to replace.
Your garage door weighs 300 to 500 pounds. Springs counterbalance that weight, making the opener's job manageable and keeping your door from slamming shut. Without working springs, your door becomes a safety hazard and a headache. Springs typically last 7 to 9 years under normal use, depending on how often you open and close your door. When one snaps, replacement is not optional; it's essential.
Two main types handle this job: torsion springs and extension springs. Knowing which you have prevents you from ordering the wrong part or getting quoted for a repair you don't actually need.
Torsion springs mount horizontally above your garage door opening. They twist and unwind to lift the door, storing energy through rotational force rather than stretching. This design is more durable, smoother, and safer than its counterpart.
Most homes built in the last 20 years use torsion springs. They last longer, require less maintenance, and balance the door more evenly. If a torsion spring snaps, you'll hear a loud bang, and your door will drop suddenly. The spring itself is under extreme tension and should never be touched without professional training.
Torsion spring replacement typically costs more than extension springs because the design is more complex and requires precise calibration. However, their longevity makes them cheaper over time.
Extension springs run vertically along both sides of your door, parallel to the horizontal tracks. When the door closes, these springs stretch and store energy. When you open the door, they contract and pull it up.
Extension springs are cheaper upfront and easier to install, which is why older homes and budget installations often use them. However, they wear faster, require more frequent adjustment, and break more often. They also present a higher safety risk because stretched springs can snap unexpectedly.
If you need a same-day repair and your door uses extension springs, you'll likely find parts readily available at local suppliers. That said, many homeowners find themselves replacing extension springs multiple times over a decade, eating away any initial savings.

Look above your garage door from inside the garage. If you see a metal rod running horizontally across the top with coils wrapped around it, you have a torsion spring. If you see two springs running vertically down each side of the door, tracking along the side rails, you have extension springs.
Don't attempt to inspect closely or touch the springs themselves. Both types are under tremendous tension and can cause serious injury or death if they fail while you're near them.
A snapped spring repair in Robertsville typically ranges from $200 to $400 for extension springs and $300 to $500 for torsion springs, including labor. If your door is older or rarely serviced, the technician may recommend replacing both springs at once rather than just the broken one. This prevents a second failure weeks later.
For detailed pricing on your specific situation, get a same-day estimate from our team. We'll inspect your spring type, assess wear, and quote you fairly without pressure.
If one spring has snapped and the other is original, replacement of both is almost always the smarter move. Springs wear at the same rate. Replacing just one means you'll likely need the second replaced within months, costing you twice in service calls.
For routine maintenance advice, check our complete garage door maintenance guide. Regular lubrication and inspection catch small issues before they become expensive emergencies.
Torsion springs cost more upfront but save money long term. Extension springs are cheaper initially but fail faster. Knowing which type you have keeps you from overpaying for the wrong repair.
If your door won't open or you've heard a loud snap, don't wait. A broken spring leaves your door stuck and potentially dangerous. Call Garage Door Robertsville at 1-330-964-6966 for a free quote and honest assessment of whether you need repair or replacement.

Can I replace just one spring instead of both? Technically yes, but it's unwise. Springs wear together, so the surviving spring will likely fail within weeks. Replacing both at once saves money on repeat service calls and prevents prolonged downtime.
How long do garage door springs actually last? Torsion springs typically last 7 to 9 years with normal use (one to two door cycles daily). Extension springs last 5 to 7 years. Frequency of use affects lifespan; commercial doors or frequently opened residential doors wear springs faster.
What's the difference in installation difficulty? Extension springs are simpler to install and require fewer tools. Torsion springs demand precise tension calibration and special equipment. Professional installation is strongly recommended for both, especially torsion springs due to safety risks.
Why is torsion spring replacement more expensive? Torsion springs require precise measurements, specialized tools, and careful balancing to function safely. Installation takes longer and demands more expertise. The cost difference is usually $100 to $200 per spring.
Are broken springs covered by homeowners insurance? Most homeowners policies exclude wear and tear, which includes spring failure. Check your policy details, but expect to pay out of pocket. Our team can discuss financing options if cost is a concern.
