Torsion Spring Repair
& Replacement in Renton, WA
If your garage door suddenly feels like it weighs 300 pounds or it only lifts about a foot before stopping, you almost certainly have a broken torsion spring. It happens without warning. One loud bang, and the door stops working. We have been fixing torsion springs across Renton and the Greater Seattle area since 2012. Same-day service, honest pricing, no guesswork.
Torsion springs do the heavy lifting every time your garage door opens. They are mounted on a shaft above the door and use stored energy to counterbalance the door's weight. When one breaks, the door becomes dead weight. You cannot safely open it by hand, and running the opener will burn out the motor. Instant Garage Doors carries a full range of torsion springs on every truck. We measure, match, and install the correct spring for your door. We also replace cables, bearing plates, and winding cones when needed. Most torsion spring jobs are done in under an hour.
What Is a Torsion Spring and How Does It Work
A torsion spring is a tightly wound steel coil mounted on a shaft that runs across the top of your garage door opening. When you close the door, the cables wrap around the cable drums and wind the spring, storing energy. When you open the door, that stored energy unwinds and helps lift the door.
The spring does about 90% of the work. Your opener just guides it. That is why a broken spring makes the door feel impossibly heavy. The counterbalance is gone.
Every part of this system matters. The bearing plates hold the shaft in place. The cable drums control how the cables spool. The winding cone is where tension gets applied. If any of these parts wear out, the whole system suffers. We inspect all of them on every torsion spring call.
Signs Your Torsion Spring Needs Attention
Loud Bang from the Garage
A torsion spring snapping sounds like a gunshot. If you heard a loud bang and the door stopped working, the spring almost certainly broke. This happens when the coil reaches the end of its cycle life and the metal fatigues.
Visible Gap in the Spring Coils
Look at the spring above your door. A broken torsion spring will have a clear gap, usually 2 to 3 inches, where the coil separated. The two halves may still be sitting on the shaft, but they are no longer connected.
Door Feels Extremely Heavy
Without the torsion spring doing its job, you are trying to lift 150 to 300 pounds of door by hand. If you disconnect the opener and try to lift the door manually, it will barely budge. This is a clear sign the spring has failed.
Door Opens a Foot Then Stops
Some openers are strong enough to lift the door a little, but they strain and reverse because the load is too much without spring assistance. The opener's safety system kicks in and stops it. This protects the motor, but your door stays stuck.
Cables Are Loose or Off the Drums
When a torsion spring breaks, it can cause the cables to unspool from the cable drums. You might see slack cables hanging beside the door or tangled around the shaft. Do not try to rewind them yourself.
Door Opens Crooked or Jerky
On a double-spring system, one spring can break while the other holds. The door opens unevenly, tilts to one side, or moves in jerky steps. This puts extra stress on the remaining spring and the tracks.
Single Spring vs Double Spring Systems
Your garage door uses either one or two torsion springs. Here is how they compare.
Single Spring
- Lower cost to replace
- Simpler installation
- Common on single-car doors
- Door is stuck when it breaks
- More stress on one spring
- Shorter lifespan due to higher load
Double Spring
- Safer: door stays partially supported if one breaks
- Each spring carries less load
- Longer lifespan for each spring
- Smoother, more balanced operation
- Higher upfront cost
- Both should be replaced together

How We Replace Torsion Springs
From the call to a working door. Here is what happens.
Inspect and Measure
We check the broken spring, measure the wire gauge, inside diameter, and length. We also inspect the cables, drums, bearing plates, and winding cones. Everything gets evaluated so nothing is missed.
Secure the Door and Release Tension
The door gets clamped to the track for safety. If the old spring still has tension, we unwind it with proper winding bars. This is the step that makes DIY dangerous. One slip and the bar can kick back hard.
Install the New Spring
We slide the new spring onto the shaft, seat the winding cone, and wind it to the correct number of turns. We replace cables and bearing plates if they show wear. On single-spring systems, we recommend upgrading to a double-spring setup.
Balance, Test, and Lubricate
We release the clamps, test the door manually for balance, then test it with the opener. The door should stay in place when you stop it halfway open. We lubricate the spring, shaft, and hinges, then clean up and walk you through everything we did.

Frequently Asked Questions
Torsion springs are the part most people never think about until something goes wrong. These are the questions we answer on almost every call.
01 What is a torsion spring and how is it different from other springs?
A torsion spring is a tightly wound coil that sits on a metal shaft above your garage door opening. It uses torque (twisting force) to lift the door. Extension springs, on the other hand, stretch along the sides of the tracks. Most homes built after the mid-1990s use torsion springs because they provide smoother operation, better balance, and last longer.
02 How do I know if I have torsion springs or extension springs?
Look above your garage door when it is closed. If you see one or two tightly wound coils running along a metal bar (shaft) directly above the opening, those are torsion springs. If you see long springs running parallel to the horizontal tracks on each side of the door, those are extension springs. If you are not sure, send us a photo and we will tell you.
03 How long do torsion springs last?
A standard torsion spring is rated for about 10,000 cycles. One cycle is one open and one close. For a household that uses the garage door 4 times a day, that works out to roughly 7 to 10 years. We also install high-cycle springs rated for 25,000 or even 50,000 cycles if you want them to last significantly longer.
04 Can I adjust the tension on my torsion spring myself?
We strongly advise against it. Torsion springs are under extreme tension and require special winding bars and training to adjust safely. A spring that slips off a winding cone can cause serious injury. If your door feels heavy, is not closing all the way, or seems unbalanced, call us and we will adjust it safely.
05 What is the difference between a single spring and a double spring system?
A single spring system uses one large torsion spring centered above the door. A double spring system uses two smaller springs, one on each side of the center bracket. Double spring setups are safer because if one spring breaks, the other keeps the door partially supported. They also tend to last longer because the load is split between two springs.
06 How do I know what size torsion spring I need?
Torsion spring sizing depends on the door weight, door height, track radius, and shaft size. Getting it wrong means the door will not balance properly and the spring will fail early. Our technicians measure and calculate the correct wire gauge, inside diameter, and spring length on every job. This is not something you should guess at.
07 What does torsion spring repair or replacement cost?
Most torsion spring replacements in the Renton area run between $180 and $350 for a single spring, or $250 to $500 for a pair. The price depends on the spring size, cycle rating, and whether other hardware like cables or bearing plates need attention. We give you an exact quote on-site before we start any work.
