Craftsman Torsion Spring Replacement: The Longmont Owner’s Guide

A Craftsman torsion spring replacement in Longmont typically runs $180 to $340 installed, including the spring, labor, and a documented photo record of the failed part and the completed work. We stock Craftsman-compatible torsion springs on our trucks and can usually complete the swap the same day we diagnose it. Most Longmont homeowners discover the problem the same way: a loud bang from the garage that sounds like a car backfiring, followed by a door that will not lift more than a few inches.

That bang is the torsion spring snapping. It is the single most common failure point on any Craftsman garage door system, and it rarely gives much warning. One morning the door works. The next, it does not. The spring sits above the closed door, wound tight under tension, and when it breaks, the door becomes effectively dead weight. The opener was never designed to lift that weight alone, which is why running the opener after a spring failure can burn out the motor in a matter of seconds.

Which Craftsman Models This Applies To

Craftsman garage doors span several decades of production, but the torsion spring setup is consistent across most of their 7-foot and 8-foot residential models sold through the 1990s, 2000s, and 2010s. The critical variable is not the Craftsman door model itself. It is the spring’s physical measurements: wire diameter, inside diameter, length, and wind direction (left-hand or right-hand). A spring that fits one Craftsman door will not necessarily fit another, even if both doors look identical from the driveway.

Most Craftsman doors use a pair of torsion springs rather than a single spring, and both should be replaced together even if only one has broken. The reasoning is straightforward: both springs have cycled the same number of times since installation, and the second one is statistically close to failing. If you have the original Craftsman paperwork, the spring specifications may be listed. If not, we measure on site. Marcus Deller’s crew will read the wire gauge, count the coils, and match the replacement before quoting anything, because the wrong spring is worse than no spring at all.

One compatibility gotcha worth knowing: some Craftsman doors from the 1980s and early 1990s used a slightly narrower torsion tube than today’s standard. If your home near Roosevelt Park or in Prospect was built in that era and the door looks original, the spring we install may need a conversion sleeve to fit the tube correctly. We check for this during the inspection, not after the door is apart. On the OEM versus aftermarket question, we stock quality aftermarket springs that meet or exceed the original specifications. OEM Craftsman springs are still available for many models, but the aftermarket equivalents we use carry the same cycle rating and arrive faster, which matters when your garage is stuck closed.

Signs Your Craftsman Torsion Spring Replacement Is Failing

A torsion spring rarely fails silently. Here are the five signs we see most often on Craftsman doors across Longmont:

• A loud bang from the garage. This is the spring snapping, not the opener. The sound is unmistakable once you have heard it. The spring breaks under tension and releases all of its stored energy in a fraction of a second.
• The door opens a few inches and stops. The opener is trying to lift the full weight of the door without the spring’s counterbalance. Every inch it moves is fighting gravity directly, and the motor will not win.
• The door feels heavy when you pull the manual release cord. A properly balanced door should feel like it weighs 8 to 10 pounds when you lift it by hand. If it feels like 80, the spring is either failing or already gone.
• Visible gap in the spring above the door. Look at the torsion tube running across the header. If you see a clean break in one of the coils, often with a half-inch gap between the two sections, the spring has failed completely.
• The door jerks or hesitates mid-travel. This can happen in the weeks before a full break, as the spring loses tension unevenly. The opener works harder on one side, and the door shudders out of level.

If you are seeing any of these, stop using the opener. The motor is not designed to compensate for a broken spring, and running it will turn a $180 spring job into a $500 opener replacement on top of it.

Replacement Cost & What’s Included

Craftsman torsion spring replacement in Longmont runs $180 to $340, and that price is quoted in writing before any work begins. The range exists honestly: the lower end covers a standard pair of springs on a 7-foot door with a common wire gauge. The upper end covers heavier 8-foot doors, higher-cycle springs rated for more open-and-close operations, or doors that need the conversion sleeve we mentioned earlier.

Every spring replacement includes both springs (we do not replace a single spring on a two-spring door), the labor to remove and install, a safety inspection of the cables, drums, and bearings, and a balance test after installation. You also get our 365-Day Done Right Promise: if the spring work is not right, we make it right. The price we quote is the price you pay. There is no “we found something else once we got in there” conversation, because the quote is written after we see the door, not before. Per Clause 1 of The Haven Standard, the written price and written scope arrive before the first wrench turns.

One thing to factor in: cable damage is common when a spring snaps, because the sudden release of tension can throw the lift cable off the drum. If your cables are frayed or jumped, expect that repair to fall in the $130-$250 range. We will show you the cable condition in the photo record before quoting it.

DIY or Call Us?

We are going to be direct here: do not attempt a torsion spring replacement yourself. This is not gatekeeping. A torsion spring holds enough stored energy to remove fingers, break bones, or worse if it releases while you are working on it. The winding and unwinding process requires specific winding bars, a careful count of quarter-turns, and an understanding of how the spring interacts with the cables and drums. We have seen the aftermath of DIY attempts on older homes near Roosevelt Park, and it is never worth the $200 saved.

What you can safely do: check for a visible break in the spring, disconnect the opener using the manual release cord, and take a photo of the spring and the door’s inside label showing the model number. That photo helps us match the part before we arrive. What you should not do: touch the bolts on the spring cones, try to tighten or loosen anything, or run the opener once the spring has failed.

If the spring is broken, call us at (970) 528-5851. We will send a technician who names the part, quotes the range, then does the work. The documentation, the written price, and the photo record all come standard. No urgency required, and no pressure applied.

Why Longmont Homeowners Choose Servo for Craftsman Spring Work

We have been operating in Longmont since 2015 under The Haven Standard, and the approach has not changed since day one: photograph the failed part before quoting the replacement. That founding rule is now Clause 4 of The Haven Standard, and it is why every visit ends with a documented photo record in your hands. You see the broken spring. You see the new spring. You see the balance test. No trust required, because the evidence is in the file.

We are independently owned and operated, not a franchise, and we are not affiliated with Craftsman. We simply work on their doors more than almost anyone else in the area, which is why we also stock parts for LiftMaster, Chamberlain, and Genie systems alongside Craftsman. Marcus Deller runs the crew, and his background sits in the mechanical trades: a Building Trades education at Queensborough Community College, over a decade of Front Range service calls, and a personal rule that no door is done until it cycles quietly three times in a row.

Every Craftsman spring replacement is quoted with a flat, written price before work starts. Calls are answered by a live person, 24/7, including holidays. Emergency calls get a named technician and an on-the-way text, not a callback window. If you have a written estimate from another company, bring it in. The Free Second Opinion applies, no coupon required.

If your Craftsman door slammed shut and will not open, or if the spring is visibly broken above the header, call (970) 528-5851 now. We will give you an honest assessment, a written price, and a clear picture of what happens next. Name the part, quote the range, then do the work.
