Clopay Cable & Drum Replacement Nationwide

Clopay Cable & Drum Replacement: The Alamo Heights Owner’s Guide

We stock and install Clopay-compatible cable and drum assemblies for most residential models in Alamo Heights, with typical installed pricing between $130 and $250. Most replacements are completed in a single visit because our trucks carry the common drum sizes and cable lengths Clopay doors use. If your door is hanging crooked, slipping down after it closes, or making a grinding clatter from one side, the cable or drum is usually the culprit.

Carl Dutton and our crew have replaced these parts on Clopay doors all over Alamo Heights, including the older ranch-style homes near Alamo Heights High School where the original hardware has been cycling since the 1980s. The cable and drum work together: the drum winds and unwinds the cable as the door moves, and when either part wears, the whole system goes out of balance.

Which Clopay Models This Applies To

Clopay uses several drum profiles across their product lines, and matching the right one matters. The most common residential series we see in Alamo Heights are the Classic Collection (steel raised-panel doors), the Gallery Collection (carriage-house styling), and the Avante Collection (full-view aluminum and glass). Each uses a different drum diameter and cable anchor setup.

To identify your part, check the sticker on the interior side of the door panel for the model number, or measure the drum itself: standard-lift residential drums are typically 4 inches in diameter, while low-headroom and high-lift applications run smaller or larger. The cable attaches either through a keyed slot or a winding notch depending on the drum generation.

We carry both OEM Clopay drums and quality aftermarket equivalents from Dura-Lift and Prime-Line that meet the same specifications. For most Alamo Heights homeowners, the aftermarket option performs identically at a lower parts cost. We are an independent service provider, not affiliated with Clopay, so we recommend what fits your door and budget without brand pressure.

Signs Your Clopay Cable & Drum Replacement Is Failing

• Door hangs crooked or one side sits lower. When a cable frays or a drum cracks, that side of the door loses support. The weight shifts to the opposite cable, pulling the door out of level and straining the opener.
• Loud grinding or clicking from one side of the track. A cracked drum will chatter against the shaft as it turns, or a frayed cable will catch and pop against the drum grooves. This sound usually starts before total failure.
• Door slips down after reaching the closed position. The drum’s gripping surface wears smooth over time, especially in Alamo Heights where humidity swings cause metal expansion and contraction. The cable slowly unwinds instead of holding tension.
• Visible fraying, rust, or broken strands on the cable. Cables are aircraft-grade galvanized steel, but they still fatigue. Once you see three or more broken strands in a one-foot section, the cable is living on borrowed time.
• Recent spring replacement but the door still feels off. New springs put fresh tension on old drums and cables. If the hardware was not replaced with the springs, the mismatch accelerates wear on all components.

Replacement Cost & What’s Included

The price range depends on whether we replace both sides or one, whether the torsion spring hardware needs rebalancing after the swap, and whether your Clopay door uses a standard or specialty drum size. We quote the flat price before any work begins. The figure covers parts, labor, lubrication of all moving components, and a full balance check.

DIY or Call Us?

There is a safe middle ground here. You can inspect: look for frayed cables, a cracked drum, or grease buildup that has hardened into grit. You can also test whether the door hangs level by closing it and measuring each bottom corner from the floor.

What you should not do is release tension from the torsion spring or attempt to wind a new cable onto the drum yourself. The spring above your door holds lethal force, and an uncontrolled release can break bones or worse. We have seen homeowners in Alamo Heights try this after watching a video, and the result is always a bigger bill than if they had called first. If the cable is off the drum or the door is stuck mid-track, the safe move is to leave it alone and call (830) 364-5701. We answer live, day or night.
