Genie Cable & Drum Replacement: The Kent Owner’s Guide

Genie cable and drum replacement in Kent typically runs $130-$250 installed, parts and labor included, and we stock the common sizes on the truck for same-visit repairs. Most homeowners discover the problem the same way: the door hangs crooked, a cable is visibly frayed or snapped, or the door jerks on its way up and won’t settle level. It’s a repair we do several times a month across Kent, and it rarely requires a second visit once we’ve matched the part to the door.

A snapped cable on a Genie door is not a subtle failure. You’ll usually see it or hear it before you call us. The drum, which is the spool above the torsion tube that winds the cable, often gets blamed but is usually the victim rather than the cause: when the cable lets go, the drum chews itself up in the process. We replace both as a pair on most Genie doors because a scored drum will destroy a new cable within weeks.

Which Genie Models This Applies To

Nearly every Genie residential door sold in the last 20 years uses a torsion spring system with a cable-and-drum pair on each side, but the drum profile varies between models. The IntelliG and TriloG series doors, common in Kent’s East Hill and West Hill subdivisions, use a tapered drum with a flat cable seat, while older Genie ProMax and screw-drive-era doors from the late 1990s and early 2000s often run a cylindrical drum with a shorter cable length. Knowing the difference matters because a mismatched drum changes the cable’s effective lift rate, and the door will not stay level through travel.

The fast way to identify your part, if you’re looking before you call, is the model tag on the end stile of the door panel or the sticker on the torsion tube. If the tag is gone, which happens often in unheated Kent garages where condensation works on stickers, we measure the drum’s outside diameter and count the cable grooves. Genie OEM drums for 7-foot residential doors are almost always 4 inches in diameter with four cable wraps at full travel; 8-foot doors step up in cable length but keep the same drum spec on most models. Aftermarket equivalents from DURA-LIFT and Garage Door Parts LLC fit most Genie doors without modification, but we carry Genie OEM drums and cables for doors still under warranty or within a few years of manufacture, because aftermarket parts can void a Genie warranty on newer units. We also stock LiftMaster and Chamberlain cable-and-drum sets for the mixed-brand garages we see around Kent, where one opener brand hangs above a different door manufacturer’s panels.

Signs Your Genie Cable & Drum Replacement Is Failing

• The door hangs visibly crooked when partially open. One cable has stretched or begun to unravel, so one side of the door is sitting lower than the other. The drum on that side is usually wearing alongside it.
• The door jerks or shudders as it moves. A cable with broken strands catches and releases inside the drum groove, causing the visible stutter. Left alone, the strands bind and the cable snaps mid-cycle.
• You can see rust or fraying on the cable itself. In Kent’s damp winters, cables sweat inside unheated garages, and surface rust becomes strand breakage within a season. Once strands begin to separate, the cable is done; there is no tightening fix.
• The door stops about a foot off the ground and won’t budge. The cable has jumped out of the drum groove and wrapped itself around the shaft or jammed between the drum and the header bracket.
• You heard a loud pop or snap during operation. The cable has parted. In some cases it took the drum’s edge with it, and the door is now running on one cable at full torsion load, which is the situation you do not want to leave overnight.

Replacement Cost & What’s Included

Genie cable and drum replacement in Kent runs $130-$250 for a standard 7-foot residential door, which includes the parts, the labor on both sides, and a written date-of-service warranty on our work. The spread accounts for the difference between a single cable swap, a cable-and-drum pair on one side, and a full both-side replacement with OEM parts. We quote the flat price before any wrench moves, per Clause 1 of The Haven Standard, and the price you sign is the price you pay at the end of the job.

What drives the range in practice is condition. When the drum is intact and only the cable failed, the job lands on the lower end. When the drum is scored, the cable snapped at the drum, and the door has been cycling on one cable for a few days, the repair involves both sides and lands higher. Either way, the written scope lists every part number and every labor step before we begin. If you’re holding an estimate from another company, bring it. We’ll give you a free second opinion on any written quote, and the comparison is apples-to-apples because we document what we found before we ask you to authorize anything.

DIY or Call Us?

What you can safely check yourself is the visible condition of the cable where it meets the bottom bracket. If you see frayed strands or a gap between the cable and the drum groove, you have a real failure and you should stop running the door. What you should not do is attempt to replace the cable yourself. The cables on a Genie door are under full torsion from the wound spring, and unless you know how to de-tension the system with the correct winding bars, you are placing your hands within inches of a loaded spring that carries enough stored energy to break bone or worse.

The failure mode we see from DIY attempts is not usually the injury, thankfully, it’s the aftermath: a cable wound backward on the drum, a door that cocks hard to one side, and a spring that lost half its tension because the set screws were loosened in the wrong sequence. By the time we’re called, the fix costs more than the original cable job. If the cable on your Genie door has failed in Kent, call us at (425) 906-3489. We’ll name the part, quote the price, then do the work. In that order.
