Clopay Cable & Drum Replacement Nationwide

Clopay Cable & Drum Replacement: The New Braunfels Owner’s Guide

Clopay cable and drum replacement in New Braunfels typically runs $130-$250 installed, and we carry the matching drums and lift cables for most Clopay residential lines on every truck. Most jobs are finished in under an hour once we verify your door’s size, weight, and track configuration. You’ll usually notice this problem first as a door that sits crooked, drops hard on one side, or makes a grinding pop when it moves.

The cable-and-drum assembly on a Clopay door does the actual lifting after the spring stores the energy. When a cable frays or a drum cracks, the door loses its geometry fast. In New Braunfels, we see this most often after a spring snaps unevenly, after a cable jumps its groove during a manual lift, or simply after fifteen years of humidity cycling through the Hill Country.

Which Clopay Models This Applies To

Clopay has used several drum designs across its lines, and matching the wrong one throws off cable wrap and door balance. The critical detail is drum diameter paired with door height and track type.

Residential lines we match regularly:

• Classic Series (steel raised-panel): Most use a 4-inch standard-lift drum for 7- or 8-foot doors. The part number is stamped on the drum hub; if it’s worn off, we measure drum diameter and cable groove pitch on-site.
• Gallery and Coachman Series (carriage-house steel or steel-composite): These often ship with high-lift or vertical-lift track in taller garages, which means a larger-drum hub, sometimes 5.5-inch. A standard drum forced onto a high-lift door will over-wrap the cable in ten cycles.
• Grand Harbor and Canyon Ridge (premium insulated or wood-composite): Heavier doors need drums rated for higher weight capacity. The cable diameter steps up from 1/8-inch to 5/32-inch on many of these.

We stock both OEM Clopay drums and quality aftermarket equivalents from DDM and Prime-Line. For most New Braunfels homeowners, the aftermarket spec matches the OEM at a lower parts cost, and we warranty the installed assembly the same either way. We are an independent service provider, not affiliated with Clopay Corporation.

To identify your part before we arrive: check the sticker on the inside top edge of your door section for the model and serial, or photograph the drum from the side with the door down so we can read any stamped markings.

Signs Your Clopay Cable & Drum Replacement Is Failing

• The door hangs lower on the left or right. When one cable frays and stretches, or a drum slips on its shaft, that side of the door loses support. The opener strains to pull uneven weight, and the door panels twist slightly in the tracks.
• A loud pop or bang, then the door won’t move. This is usually a cable snapping under load or jumping off a cracked drum. The remaining cable carries the full door weight until you stop using it, which risks bending the track or damaging the top section.
• Visible fraying, rust, or broken strands on the cable. Clopay cables are galvanized, but in New Braunfels the humidity swings from March through June accelerate surface corrosion. Once you see three or more broken strands in a six-inch span, the cable is living on borrowed time.
• The drum wobbles or grinds when the door moves. A cracked drum hub spins off-center, chewing the cable into the drum casting. We replaced a set last month on a Classic Series door off Loop 337 where the homeowner had run it for two weeks that way; the drum had worn a groove that damaged the cable beyond reuse.
• The cable overlaps or “birdnests” on the drum. This means the drum’s grooves are worn smooth, or the cable was improperly seated during a previous repair. The fix is drum replacement, not just reseating the cable, or it will happen again in a month.

Replacement Cost & What’s Included

The range depends on door height (8-foot doors need longer cables), whether we replace one side or both (we recommend both when one fails, since the pair has seen identical cycles), and whether the cable came off because a spring is also failing. We state the flat price before any work starts. No surprises on the bill. Every cable and drum replacement carries our 90-Day Done Right Promise in writing.

DIY or Call Us?

There is a safe middle ground here. You can look. You should not touch.

With the door fully closed and the opener disconnected, a homeowner can safely inspect the cables for fraying and the drums for cracks or wobble. Do not pull the emergency release with the door open, and do not attempt to adjust or remove a cable yourself. These cables are under spring tension even when the door appears still; a slipped wrench or miscounted turn can release stored energy without warning. We have seen laceration injuries from exactly this.

If your inspection shows wear, or if the door is already crooked or stuck, call us. We arrive with the right Clopay-compatible drums and cables already on the truck, measure your door’s spec on-site, and finish most replacements in a single visit. Tell me what it is doing wrong. We will take it from there.
