Amarr Cable & Drum Replacement: The Tacoma Owner’s Guide

Amarr cable and drum replacement in Tacoma typically runs $130-$250 installed, and we stock the common Amarr-compatible sizes on every truck. Most jobs finish in under 90 minutes once we confirm the drum diameter and cable length against your door’s height and weight. If your door is hanging crooked, dropping fast, or the cables look frayed where they wrap the drum, that’s usually what we’re looking at.

Homeowners in the North End and around Point Defiance notice this failure first thing in the morning. The door opens six inches and stops, or one side lifts while the other sags. Sometimes it’s a loud thwack from the garage when the cable slips a groove on the drum. The drum itself, a cast-aluminum or steel wheel that sits on the torsion tube, develops worn grooves or cracks. The cable, a 7×19 galvanized aircraft cable rated for the door weight, frays from moisture and the salt air that blows in off Puget Sound.

Which Amarr Models This Applies To

Amarr uses two main drum families across their residential lines, and getting the wrong one means your door won’t balance. The standard-lift drum, found on most Amarr Classica, Stratford, and Oak Summit doors in Tacoma’s 7-foot and 8-foot ceiling heights, has a 4-inch diameter with a consistent cable pitch. The high-lift or vertical-lift drum, used on taller track configurations common in newer Lakewood and University Place builds, steps up in diameter to take up cable faster as the door rises.

Check the label. Amarr stamps a model sticker on the interior face of the bottom section, usually behind the weatherstrip. The drum itself may have a casting number, but corrosion often eats it. We measure drum diameter with calipers and count cable wraps at full open. Amarr’s OEM drums are cast with their logo, but quality aftermarket equivalents from DDM and Garage Door Supply House match the spec and carry the same cycle rating at roughly 60% of dealer parts cost. For doors installed between 2015 and 2020, watch for the transitional drum design Amarr used before standardizing on the current casting. The old version has a sharper cable groove radius that accelerates fraying.

Signs Your Amarr Cable & Drum Replacement Is Failing

• Door hangs crooked or one side drops faster. The cable has slipped off the drum groove or the drum itself has cracked, letting the cable seat unevenly. The torsion spring still pulls, but one side of the door carries more load.
• Loud bang or snap from the garage, then the door won’t move. A cable has broken under tension. The remaining cable and spring now pull the door unevenly, which can twist the door sections or pull the door off the track.
• Frayed or rusted cable where it wraps the drum. Moisture gets trapped between cable wraps, especially in unheated garages through Tacoma’s wet winters. The 7×19 strands oxidize from the inside out.
• Door opens six to twelve inches and stops hard. The cable has overlapped on the drum, creating a binding knot. This usually follows a previous repair where the cable wasn’t tensioned and wound correctly.
• Visible cracks or chips in the drum casting. Cast aluminum fatigues over 15,000 to 20,000 cycles. A cracked drum will eventually shatter under load, dropping the door and releasing stored torsion energy.

Replacement Cost & What’s Included

Amarr cable and drum replacement in Tacoma: $130-$250 installed.

The range depends on drum type and whether we’re matching a single failed part or replacing cable and drum together. We don’t replace one cable; they wear as a pair. The price we write down is the price you pay. Clause 1 of The Haven Standard: flat, written scope and price before any work starts. The $130-$250 includes re-tensioning the torsion spring to match the new drum diameter, a step some competitors skip. Your documented photo record shows the old drum’s wear pattern, the new part installed, and the door balanced at mid-travel. The 365-Day Done Right Promise covers the work.

DIY or Call Us?

Here’s what you can safely check yourself. Look at the cables with the door closed. Fraying, rust, or a cable sitting off the drum groove is visible without touching anything. Check if the door lifts manually with the opener disconnected. If one side feels heavier, the cable system is compromised.

What you should not do: unwind the torsion spring, remove the cable from the drum, or attempt to rewind a slipped cable. The torsion spring stores roughly 100 foot-pounds of torque on a standard 16-foot Amarr door. A winding bar slipping or a cable snapping under tension causes serious injury. We’ve seen homeowners in the Proctor District and along Ruston Way who tried to “just reseat” a cable and ended up with a door off the tracks and a bent top section. Name the part. Quote the range. Then pick up the wrench. That’s how we work, and it’s why we carry the tools to release tension safely.
