We inspect the full system, show you exactly what failed, and give you a clear price before we start any work. No surprises, no upsells, just a working door.
What Happens When a Spring Breaks
Your Door Will Not Open
The opener strains but the door barely lifts off the ground, or it does not move at all. Without the spring handling most of the weight, the motor cannot do its job.
You Heard a Loud Bang
A spring breaking sounds like a gunshot or a firecracker going off in your garage. If you heard a loud bang and did not find the source, check the spring above your door for a gap in the coils.
The Door Feels Extremely Heavy
Without spring tension, you are lifting 150 to 300+ pounds of solid door. If the door feels impossibly heavy when you try to raise it by hand, the spring has failed.
Torsion vs Extension Springs
Torsion Springs
Mounted on a metal shaft directly above the door opening. These springs twist and coil on the shaft to generate the torque that lifts the door.
- Smoother, more controlled door movement
- Longer lifespan: 15,000 to 20,000 cycles
- Better balance, less wear on your opener
- Safer if they break (contained on the shaft)
- Standard on most homes built after 2000
Extension Springs
Mounted along the horizontal tracks on each side of the door. These springs stretch and contract to counterbalance the door weight.
- Lower upfront cost
- Easier to find replacement parts
- Good for lighter, single-car doors
- Lifespan: 8,000 to 10,000 cycles
- Safety cables recommended to contain breakage

Frequently Asked Questions
A broken spring is usually the first time most people call a garage door company. Here is what you actually need to know.
01 How much does broken spring replacement cost?
Most single spring replacements run between $150 and $350 depending on the spring type, door weight, and whether you need a torsion or extension spring. Replacing both springs at once is usually $200 to $500 total. We give you a clear quote on-site before any work starts, and there are no hidden fees.
02 How long does it take to replace a broken spring?
Most broken spring replacements take 30 to 60 minutes once the technician is on-site. We carry the most common torsion and extension springs on every truck, so there is rarely a need for a second visit. Including inspection, replacement, balancing, and safety testing, you can expect about an hour from start to finish.
03 Can I open my garage door with a broken spring?
We strongly advise against it. Without the spring counterbalancing the weight, your door weighs 150 to 300 pounds or more. Trying to lift it manually risks back injury, and running the opener with a broken spring can burn out the motor or damage the door panels. Keep the door closed and call a professional.
04 One spring broke. Should I replace both?
Yes, and here is why. Both springs were installed at the same time, so they have the same wear. If one broke, the other is close behind. Replacing both now saves you a second service call and the cost of another visit fee. It also keeps the door evenly balanced, which protects your opener and tracks.
05 What is the difference between torsion and extension springs?
Torsion springs mount on a shaft above the door opening and twist to lift the door. They last longer (15,000 to 20,000 cycles), operate more smoothly, and are safer because they stay on the shaft if they break. Extension springs run along the tracks on each side and stretch to lift the door. They cost less upfront but have a shorter lifespan (8,000 to 10,000 cycles). Most Renton homes built after 2000 use torsion springs.
06 Are there warning signs before a spring breaks?
Yes. Watch for the door feeling heavier than usual, the opener struggling or straining, visible rust or corrosion on the spring coils, the door not staying open halfway when disconnected from the opener, or squeaking and grinding noises during operation. If you notice any of these, a tune-up or proactive replacement can prevent a sudden failure.
07 Is it dangerous to replace a garage door spring myself?
Garage door springs are under extreme tension. A standard torsion spring holds over 100 pounds of force, and an improperly wound spring can cause serious injury. Every year, thousands of homeowners are hurt attempting DIY spring repairs. This is one job that always needs a trained, licensed technician with the right tools.
