Garage Door Drum Replacement in Rochester, MN
Cable drums are the spooled cylinders at each end of the torsion shaft that wind the lift cables as your door goes up. When a drum cracks, develops a groove, or shifts on the shaft, the cable winds unevenly and the door goes out of level fast. Drum problems often get mistaken for spring issues because the symptoms look similar. Replacing a drum requires releasing spring tension first, which is why this isn't a DIY repair.

How It Works
Our Process for Garage Door Drum Replacement
- 1
Spring Tension Release
Torsion springs are safely unwound before any work touches the drums — this step is non-negotiable and can't be skipped.
- 2
Drum Removal
Set screws are loosened and the damaged drum is slid off the torsion shaft, with cable position noted before removal.
- 3
Cable Inspection
Cables are checked for fraying or kinking caused by the failed drum before the new drum goes on — we replace cable if it's compromised.
- 4
Reinstall and Re-tension
New drum is seated, cable is wound to correct position, and springs are re-tensioned to restore proper balance.
Rochester Context
Why this matters in Rochester
Rochester's humidity swings between summer and winter accelerate corrosion on cable drum surfaces. We see more grooved and cracked drums on doors in older neighborhoods where the hardware has been cycling through fifteen or twenty winters.
Straight Talk
About pricing & scope
Drums come in different cable-wrap diameters matched to your spring setup. Using the wrong drum throws off spring tension calculations, so we match the replacement to your existing hardware rather than grabbing whatever is on hand.
