Garage Door Drum Replacement in Portland, ME
The cable drums are the spooled cylinders at each end of the torsion shaft that wind and unwind the lift cables as your door moves. A cracked drum or one with a worn cable groove causes the cable to slip, bunch, or snap off entirely. Most homeowners don't notice a drum problem until one cable goes slack and the door drops on one side. We replace drums in matched pairs so both sides wind at the same rate.

When to Call
When You Need Garage Door Drum Replacement
- One side of your door is lower than the other when fully open

- You hear a sharp snapping sound followed by a crooked door
- The cable keeps jumping off the drum every few cycles
How It Works
Our Process for Garage Door Drum Replacement
- 1
Spring Tension Release
We safely unwind the torsion spring before touching the drums — this step is non-negotiable and must be done correctly.
- 2
Drum Removal and Inspection
Both drums come off the shaft so we can check for cracking, worn grooves, and any cable damage that caused or resulted from failure.
- 3
Matched Pair Installation
New drums are installed in a matched set, seated properly on the shaft, and set screws are torqued to prevent any rotation slippage.
- 4
Cable Wind and Balance Check
Cables are wound with equal tension on both sides, spring tension is restored, and the door is tested for level travel.
Portland Context
Why this matters in Portland
Portland winters mean repeated freeze-thaw cycles that stress cable drums more than most people expect. Drums on doors that weren't properly balanced coming into winter tend to crack at the hub during the coldest months, usually January into February.
Straight Talk
About pricing & scope
If the cables themselves are frayed or kinked from riding a bad drum groove, those need replacement too — reusing damaged cables on new drums is a short-term fix. Spring condition also affects the overall scope of the job.
