Clopay Cable & Drum Replacement Nationwide

Clopay Cable & Drum Replacement: The Seattle Owner’s Guide

Clopay cable and drum replacement in Seattle typically runs $155-$295 installed, and we stock the common Clopay drum sizes and cable lengths on every truck. Most replacements are finished in under an hour, same day you call. You will usually notice the problem when the door hangs crooked, one side lifts faster than the other, or you spot a frayed cable collecting rust near the bottom bracket.

We have been replacing these parts on Clopay doors across Seattle since 2016. The wet winters here do the real damage: moisture works into the cable strands, the drum grooves wear from grit tracked in on car tires, and eventually something gives. Tell me what it’s doing. We’ll sort the rest out from there.

Which Clopay Models This Applies To

Clopay uses several drum and cable configurations across their product lines, and matching the wrong one will throw your door’s balance off within a week. The most common in Seattle are the standard-lift 4-inch drums found on Clopay’s Classic Collection and Gallery Collection steel doors, and the 5.5-inch low-headroom drums used in tighter garages around Capitol Hill and Wallingford where builders squeezed every inch. Clopay’s Canyon Ridge and Coachman wood-composite lines often ship with heavier 8- or 9-foot cable sets and larger diameter drums to handle the extra panel weight.

To identify yours, check the sticker on the interior side of the top panel for the model number, then measure the drum diameter across the widest groove and count the cable wraps at full door height. Clopay’s OEM part numbers start with a series prefix (like 0120xxx for standard drums), but we also carry DASMA-compatible aftermarket equivalents that meet the same torque specs and cost less. The aftermarket cables we use are galvanized aircraft-grade 7×19 strand, same as Clopay’s, because the cheaper 7×7 flex cable will not survive two Seattle winters without fraying.

One gotcha we see repeatedly: Clopay’s newer Intellicore insulated doors use a slightly wider drum hub that can bind if you install a generic replacement. We measure before we quote so you do not get a second trip.

Signs Your Clopay Cable & Drum Replacement Is Failing

• The door hangs crooked when closed. One cable has stretched or the drum has slipped on the torsion tube, so the lift is uneven. The gap at the bottom seal is usually the first thing owners notice, especially on sloped Seattle driveways where water pools on the low side.
• A loud bang or snap from the garage, then the door will not move. The cable has broken under load. Clopay cables typically fail at the bottom loop where moisture collects, or at the drum anchor where repeated bending fatigues the strand.
• The door rises faster on one side and tilts in the track. The drum is not winding cable evenly, often because the set screws have loosened or the drum casting has cracked at the hub. We see this more on Clopay doors in West Seattle near the water where salt air accelerates corrosion.
• Visible rust, fraying, or broken strands on the cable. Any fraying means the cable is past due. A single broken strand reduces capacity more than most owners realize, and a full snap under tension can damage the door panel or the opener rail.
• The opener strains or reverses when the door is nearly closed. The cable has slipped off the drum and the door is binding in the track. Running the opener in this condition will strip the opener gear or bend a track section.

Replacement Cost & What’s Included

Clopay cable and drum replacement in Seattle runs $155-$295 installed, depending on whether we are replacing one cable and drum or both sides, and whether the torsion spring needs retensioning after the swap. Here is how that breaks down:

• Single cable and drum replacement: $155-$220
• Both cables and both drums: $220-$295
• Torsion spring retensioning (if needed to rebalance): included in the upper range, or $210-$400 if the spring itself is failing

The price covers the parts, labor, disposal of the old hardware, and a full balance and safety check before we leave. We state the flat price before touching anything. The work is covered by our 90-Day Done Right Promise, in writing on every invoice. If it is not right, we come back. No paperwork to file, no argument.

Seniors and veterans receive a standing 5% discount. Repairs over $250 qualify for $50 off.

DIY or Call Us?

There are a few things you can safely check yourself. Look at the cables for fraying or rust. Watch the door as it opens to see if one side leads. Check whether the cables are seated in the drum grooves. These observations help us diagnose over the phone.

But replacing a garage door cable is not a homeowner repair. The cables are under hundreds of pounds of tension from the torsion spring. A slip during installation can send a drum spinning or a cable whipping. We have seen DIY attempts bend track, damage panels, and cause injuries that required emergency care. Greg Halvorsen learned this trade at Renton Technical College under instructors who drilled one rule: if it is not right, do it again. That applies double to anything under spring tension.

We carry Clopay-compatible cables and drums on every truck, so most replacements are finished in a single visit. Call (833) 549-7759 and a live person will pick up, day or night.
