Clopay Cable & Drum Replacement: The Van Nuys Owner’s Guide

Clopay cable and drum replacement in Van Nuys typically runs $130-$250 installed, and we stock the common Clopay drum sizes and cable lengths on our trucks for same-day completion. Most jobs take under 90 minutes once we’re on site. You’ll usually notice the problem when the door hangs crooked, one side lifts faster than the other, or you spot a frayed cable hanging loose above the track.

Which Clopay Models This Applies To

Clopay uses several drum profiles across their residential lines, and matching the wrong one throws off your door’s cable wrap geometry. The EZ-Set torsion system found on many Clopay 8000 and 9000 series steel doors uses a narrower 4-inch diameter drum with a specific left-hand or right-hand wind orientation stamped into the casting. Classic Collection wood-composite doors and the Avante full-view aluminum line often run standard-lift 5-inch drums, but the cable anchor point differs between the pinch-resistant bottom fixture Clopay uses and generic aftermarket equivalents.

We carry both OEM Clopay drums and quality aftermarket matches from DDM and Prime-Line that meet the same cast-iron spec. For cables, we stock 1/8-inch and 3/32-inch galvanized aircraft cable in 7 x 7 and 7 x 19 weave patterns. The 7 x 19 flexes better for doors with tighter radius track, which we see frequently in the shorter ceiling heights common in Van Nuys ranch homes built in the 1960s and 70s. Check the sticker on your door’s interior panel for the model number, or measure your drum’s diameter and note the cable groove count. Four grooves means standard lift; more grooves indicates a high-lift or vertical-lift application that needs exact matching.

Signs Your Clopay Cable & Drum Replacement Is Failing

• The door sits crooked when closed. One cable has stretched or slipped on its drum, leaving that side of the door an inch or two lower. In Van Nuys, we see this often after summer heat cycles have worked a cable loose from a worn drum groove.
• Loud clanging or popping when the opener engages. A frayed cable is catching and releasing against the drum flange. The sound echoes through the garage because the drum is transmitting vibration straight into the torsion tube.
• Visible rust dust or orange flakes on the horizontal track. The cable is corroding from the inside out. San Fernando Valley air carries enough moisture from marine influence that galvanized cables degrade faster than they do inland, especially on north-facing garage doors that never fully dry.
• The drum spins but the door barely moves. The set screws have backed off and the drum is freewheeling on the torsion shaft. This usually follows a previous repair where the screws were not torqued to Clopay’s 35-40 ft-lb spec.
• Cable hangs slack with the door fully open. The drum’s retaining collar has cracked or the cable has jumped its groove and wedged behind the drum. Either way, the door is running on a single cable and the remaining one is carrying double its designed load.

Replacement Cost & What’s Included

The range depends on whether we’re matching a standard drum or sourcing a specific Clopay high-lift profile, and whether the torsion tube needs rebalancing after the swap. Every quote is flat and stated before we start. Parts, labor, lubrication of all contact points, and a full safety check of the spring tension are included. The work is covered by our 90-Day Done Right Promise in writing. If something’s not right, we come back. No paperwork to file, no argument.

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

DIY or Call Us?

You can safely inspect your cables from the ground with the door closed. Look for fraying, rust, or slack. Check if the door sits level. But do not attempt to unwind the torsion spring to free a jammed cable or swap a drum yourself. The spring stores enough torque to cause serious injury if the winding bars slip. We’ve responded to calls in Van Nuys where a homeowner’s socket wrench slipped off the set screw and the torsion tube spun freely.

If the cable has simply jumped its groove and the door is still balanced, some owners can reseat it with the door fully open and clamped. Anything involving drum removal, set screw torque, or spring adjustment belongs to a trained technician. We carry the right drums and cables for Clopay systems on every truck, and most replacements finish in a single visit. Call (747) 836-1998 and we’ll quote the flat price before we head out.
