Craftsman Torsion Spring Replacement: The Simi Valley Owner’s Guide
A Craftsman torsion spring replacement in Simi Valley runs $180-$340 installed, including the new spring pair, labor, and a documented photo record of what we found and what we did. We stock Craftsman-compatible torsion springs on the truck, so most replacements happen the same day we arrive. The typical call starts with a sound: a loud bang from the garage that sounds like someone dropped a barbell on concrete, followed by a door that won’t lift more than a few inches.

That bang is the torsion spring snapping. It’s the single most common failure on Craftsman garage doors in Simi Valley, and it happens without much warning. The spring sits above the closed door, wound tight under high tension, and it takes the entire weight of the door every time it opens or closes. When it breaks, the door becomes dead weight, usually between 150 and 250 pounds depending on the model.
We’ve replaced torsion springs on Craftsman doors all over Simi Valley, from the newer builds near Big Sky to the older track homes off Erringer Road. The failure pattern is consistent whether the door is 8 years old or 20. Here’s what you need to know before you call.
Which Craftsman Models This Applies To
Craftsman garage doors were sold through Sears for decades, and most residential models use one of two torsion spring systems: standard torsion (one or two springs mounted on a shaft above the door) or the EZ-Set / Quick-Install system that Craftsman marketed as a DIY-friendly alternative in the 2000s and 2010s. The EZ-Set system uses a winding bolt instead of traditional winding bars, which changes how the spring gets tensioned but not how it fails.
If you’re trying to identify what you have, look at the spring itself. Standard torsion springs sit exposed on the shaft. Models like the Craftsman 57915, 57918, and 57595 series use these. The EZ-Set versions, common on doors sold between roughly 2006 and 2016, have a black plastic housing over the spring with a bolt at the end. We handle both, but the parts are not interchangeable.
The critical measurement for any torsion spring is wire diameter, usually between 0.207 and 0.250 inches on Craftsman residential doors, along with the spring length and inside diameter. We photograph the spring, measure it on-site, and match the replacement to the existing spring’s specs, not just the door’s model number. That matters because a previous owner or a previous repair might have changed the spring, and the door’s listed spec is no longer what’s actually up there.
For OEM versus aftermarket: Craftsman-branded springs are no longer manufactured, since Sears discontinued the Craftsman garage door line. What’s sold as “OEM” today is almost always new-old stock or a third-party part in Craftsman-branded packaging. We use quality aftermarket springs from US manufacturers that match or exceed the original wire gauge and cycle rating. You get the same performance, usually at a better price, and we warranty the work regardless of whose name is on the spring.
Servo Garage Doors Simi Valley is an independent service provider. We’re not affiliated with Craftsman or Sears, but we stock Craftsman-compatible parts and service these doors daily.

Signs Your Craftsman Torsion Spring Is Failing

- The loud bang. This is the spring snapping clean through, usually at the midpoint or at the winding cone. It’s unmistakable and it means the spring is done. No repair, no patch. Replacement, not repair.
- The door opens 3 to 6 inches and stops. The opener is trying to lift a door the spring no longer counterbalances. Continuing to run the opener this way will eventually strip the opener gear or burn out the motor.
- Visible gap in the spring coil. A broken torsion spring will show a clear separation, often a one- to two-inch gap where the coil snapped. If you see this, the spring has already failed even if the opener still technically moves the door.
- The door feels heavy when you pull the manual release. A healthy torsion spring lets you lift the door with one hand. If you’re using both hands and your back is complaining, the spring has lost most of its tension, either through age or internal cracking.
- The door slams down if the opener lets go. A door with no functioning spring is a falling hazard. If you’ve experienced a fast drop, stop using the door and call us. This is not a “monitor it and see” situation.

AfterReplacement Cost & What’s Included
In Simi Valley, a Craftsman torsion spring replacement runs $180-$340 installed. That range covers a single spring on the low end up to a dual-spring system with heavier-gauge wire on the high end. The price is flat and written before we touch anything, per Clause 1 of The Haven Standard. You’ll know the exact number before any work starts, and that number doesn’t change once we’re in the garage.
- Spring(s): $80-$170 of the total, depending on gauge and length
- Labor and setup: $100-$170, including unwinding any remaining spring(s), setting correct tension, and balancing the door
- Documented photo record: included, not optional. You get photos of the failed spring, the new spring installed, and the final balanced position.
- 365-Day Done Right Promise: if the spring installation isn’t right, we make it right. That’s in writing.
The range exists because two doors on the same block can have different spring requirements. A single-car Craftsman door with a 0.207-inch spring will land at the bottom of the range. A dual-spring 16-foot door with 0.250-inch wire will land at the top. We’ll tell you which one you have after we measure, and the quote comes before the work, not after.
DIY or Call Us?

We’re going to be straight with you: torsion springs are dangerous. These springs hold enough tension to break fingers, wrists, or worse if they release the wrong way. The winding and unwinding process requires specific tools (winding bars, not screwdrivers) and a technique that takes years to get right. We’ve seen the aftermath of DIY attempts, and it’s not worth the money saved. Marcus Deller has been doing garage door work for over two decades, and even with that experience, this is the one repair where his crew treats every spring like it’s fully wound until proven otherwise.
What you can safely do: check the spring visually (don’t touch it), note whether you have one or two springs, measure the door width, and look for any label or sticker on the door or opener with a model number. That information helps us quote accurately over the phone. What you shouldn’t do: attempt to unwind, rewind, or remove anything attached to the spring shaft.
If you’ve already released the opener and the door is sitting on the ground, leave it there. Call (661) 964-4530 and we’ll have a technician out the same day. Name the part. Quote the range. Then pick up the wrench.
FAQs
A Craftsman torsion spring in Simi Valley typically lasts 7 to 12 years, depending on how many cycles it was rated for and how often the door runs. Simi Valley’s dry heat doesn’t cause the rust issues you’d see in coastal areas, but the thermal swings between cool nights and 100-degree summer days add stress to the metal over time. If your home was built around 2015 and the springs are original, you’re at or past the typical lifespan. If we replace one spring on a dual-spring door, we’ll show you the condition of the second one and quote replacement for both if it’s near failure. Call (661) 964-4530 for an exact quote; estimates are free.
No. A broken torsion spring cannot be repaired. The steel has snapped through the coil, and there’s no welding or patching that restores the spring’s rated tension safely. It gets replaced with a new spring matched to the original specs. That’s the only correct fix.
Most Craftsman torsion spring replacements in Simi Valley take 45 to 90 minutes from arrival to a balanced, tested door. That includes unwinding the old spring(s), installing the new one(s), setting correct tension, lubricating moving parts, and running the door through several open/close cycles. The photo record we hand you at the end adds about five minutes and is worth every one.
Yes. Our trucks carry a full range of torsion spring sizes, including the wire gauges and lengths common on Craftsman residential doors. We also stock parts for LiftMaster, Chamberlain, and Genie openers, so if the broken spring has taken out your opener along the way, we can quote and fix that the same visit. Call (661) 964-4530 for same-day service and an upfront written price.
