Clopay Torsion Spring Replacement: The Longmont Owner’s Guide
We replace Clopay torsion springs in Longmont with Clopay-compatible parts, and most jobs cost between $180 and $340 installed, depending on the spring’s wire gauge, inside diameter, and length. You’ll usually hear it before you see it: a torsion spring lets go with a sharp crack that sounds like someone hit the garage wall with a framing hammer, and the door either won’t lift or jerks up a few inches and stops. Servo Garage Doors Longmont keeps Clopay-spec spring stock on the truck, so we can usually get your door cycling the same day. Here’s how to know what you’re dealing with, what it costs in this market, and when you should stop testing the door by hand.
Which Clopay Models This Applies To
Clopay builds torsion systems across three main residential lines: the Classic steel collection, the Gallery collection (steel with optional insulation), and the Reserve collection (wood-look and carriage-house doors). The torsion spring we install is matched to the door’s weight and height, not just the Clopay model name. A 16×7 Reserve wood-look door uses a different spring than a 9×7 Classic non-insulated door, even if both carry the Clopay badge. Inside diameter on Clopay residential springs is typically 2 inches, though older doors and lighter models sometimes run 1.75 inches, and wire gauges we see in Longmont range from .207 up to .250 depending on door weight. The reliable way to identify your spring is the color code painted on the cone or the end of the coil, plus the wire size, inside diameter, and overall length measured off the existing spring, not a guess from the door’s brand. We install new springs to that measured spec.
On the OEM-versus-aftermarket question: Clopay does not sell springs directly to homeowners, and the spring on your door from the factory is likely wound to a spec set by the door’s build weight. We use springs from major American manufacturers that match those specs by measurement. The brand on the spring matters less than the wire gauge, coil length, and cycle rating, and we can tell you what we measured, in writing, before you pay for anything. Servo Garage Doors Longmont is an independent service provider; we’re not a Clopay dealer or an extension of the Clopay brand, and we don’t pretend to be. We just fix the door correctly and document what we did.
Signs Your Clopay Torsion Spring Replacement Is Failing

- The door won’t open, or only opens a few inches. A garage door with one broken torsion spring loses roughly half its lift, and the opener motor alone isn’t strong enough to compensate. If the door feels like it weighs 200 pounds, that’s because it does.
- A visible gap in the coil. When a torsion spring breaks, the coil often separates cleanly, leaving a two-to-three-inch gap you can see from the garage floor. The two halves stay on the torsion tube, but the spring is dead.
- Cables are loose or have come off the drum. This is the part owners in Longmont often notice first: one lift cable hangs slack while the other is taut. The spring failure released tension, and that slack is the symptom, not the disease.
- The door sits crooked or drops fast on one side. When one spring breaks and the other still holds, the door jerks and binds at the top of the track. Testing the door repeatedly while it’s in this state wears out the opener gear and can pull the track out of square.
- You heard a loud bang from the garage during the night. Springs in Colorado don’t usually fail quietly. A broken torsion spring sounds like a single hard impact, and we’ve had customers in the Prospect neighborhood describe it as a car door slammed inside the garage. Nobody was in there. It was the spring.

AfterReplacement Cost & What’s Included
Clopay torsion spring replacement in Longmont runs $180 to $340 installed, and the price varies by spring size, not by how much the technician feels like charging that day. A single .225-wire spring on a 9×7 door lands near the bottom of that range, while a .250-wire spring on a heavy insulated or wood-look door lands near the top. Here’s the line-item breakdown we run through before any work starts:
- Diagnostic and measurement: included. We measure wire gauge, inside diameter, and length on site.
- Spring(s): $110-$260 per spring, depending on spec.
- Labor: $70-$90 for the replacement, including winding, balancing, and cycling the door three times.
- Documented photo record: included. You get photos of the failed spring before we touch it and the new spring after it’s wound.
The flat, written price we hand you before work starts covers everything above. That’s Clause 1 of The Haven Standard: written price and written scope before any work begins, no exceptions, no verbal ballpark that turns into a bigger invoice. If the price changes once we see the spring, we tell you before ordering anything and you approve it in writing. Every Clopay spring replacement we do carries our 365-Day Done Right Promise: if it’s not done right, we make it right.
DIY or Call Us?

Replacing a torsion spring yourself is the point where a $200 repair becomes a hospital trip. These springs are wound under enough tension to lift a 300-pound door, and when that tension releases into a winding bar that slips, it breaks fingers, hands, and faces. We’ll say it plainly: this is not a weekend project, and the YouTube video skips the part where the cone splits and the bar kicks back. What you can safely check: the gap in the coil, the looseness of the lift cables, which spring is broken, and the Clopay model plate on the inside of the door panel. That’s useful information to have when you call. The actual replacement, including the unwinding of the old spring, winding of the new one, and balance tuning, is why we carry winding bars and why Marcus Deller’s crew has done thousands of these. Name the part, quote the range, then do the work. Call (970) 528-5851 and we’ll name the spring, give you a written price, and get it done.
FAQs
A Clopay torsion spring in Longmont typically lasts 7 to 10 years, and the number that matters is cycles, not calendar years. Most residential springs are rated for 10,000 cycles, and a door that opens three times a day hits that in about nine years. Colorado’s dry air helps the steel avoid rust, but the rapid temperature swings of a Front Range winter put real expansion-and-contraction stress on the wire, and we’ve seen springs in the Longmont area fail at six years when they were undersized from the start. Give us a call at (970) 528-5851 and we’ll measure what’s on your door.
No. A broken torsion spring cannot be welded, spliced, or re-wound, because the break removes the structural integrity of the spring, and any repair attempt leaves the spring loaded with tension that can release unpredictably. The spring is replaced, not repaired, and we show you the broken one before it comes off the tube. Call (970) 528-5851 for a written quote on a replacement.
Most Clopay torsion spring replacements in Longmont take 45 to 90 minutes, including the time to measure, install, wind, and balance the new spring. The time depends on whether we’re replacing one spring or both: we recommend replacing both springs on a two-spring door even if one still holds, because the unbroken spring has the same cycle count as the broken one and will fail on its own schedule. If you need this done today, call (970) 528-5851 and we’ll confirm the next available technician.
We stock a full range of torsion spring wire gauges, inside diameters, and lengths on our service vehicles, along with Clopay-compatible drums, cables, and spring cones, so most Longmont jobs are done in one visit. When a spring is outside our truck stock, we usually have it from our Longmont supplier the same day. Call (970) 528-5851 with the color code or measurements from your current spring and we’ll tell you what we’re bringing.
