Garage door repair in Troy, Michigan
Cable & Roller Repair
One side hangs lower, a cable is off the drum, or the door shakes and binds.
Repair first. Replace only when it makes sense.
A clear diagnosis before the work begins.
Cables and rollers work together to keep a heavy door level and inside its tracks. I identify the failed part, correct the underlying tension or alignment problem, replace worn hardware, and verify smooth travel through the full opening.
You will know what failed, what the repair includes, and the price before I begin. Most common repairs can be completed during the visit when the required parts are available.
What the symptoms can mean
Catch the problem before more parts are damaged.
A garage door is one connected lifting system. The visible symptom is often only the first clue.
Common causes
- Cable corrosion, fraying, or fatigue near the bottom bracket
- A broken spring or loss of tension allowed the cable to unwrap
- The door hit an obstruction and changed the cable tension from side to side
How I approach the repair
Diagnose. Correct. Test.
The goal is not only to make the door move again. It is to restore controlled, balanced operation and reduce the chance of the same failure returning.
- 01
Control the door weight
I secure the door before touching a cable because the bottom fixtures and drums can be under significant force.
- 02
Inspect both sides
Both cables, drums, bottom brackets, rollers, and tracks are checked so a second developing failure is not missed.
- 03
Set equal tension
The lifting cables are routed and tensioned evenly, then the door is balanced and cycled through the tracks.
Questions homeowners ask
Cable & Roller Repair FAQ
Why did only one cable come loose?
An obstruction, uneven track, failing roller, spring problem, or worn cable can change tension on one side first. The cause matters as much as putting the cable back.
Can a frayed cable wait?
A cable with broken strands has already lost strength. Because cable failure can make the door drop or go crooked, it should be inspected before continued use.
Do not keep forcing a damaged door.
