What you see: one side low, a loose cable, a door that jams
A door that sits lower on one side, a cable lying slack or on the floor, a cable that has left its drum or pulley, wire strands standing out of a cable, or a door that jams part-way up all point to a cable problem. A cable can fail with a bang too, so a loud noise alone does not say which of the spring or the cable let go. A symptom cannot tell us which part failed, and we give no frequency for any cause.
DASMA advises owners to look at the cables, from the floor up to the bottom brackets, for fraying or wear. That is a look, not a repair. Stay out from under the door, and take a photograph from a distance if you can.
Cable repair costs in Michigan: our estimate and the evidence
Our estimate for a cable repair in Michigan is $115 to $350 per repair. It is a model, not a quote, built from national published ranges and adjusted for what Michigan garage door technicians are paid. Ask whether the price covers both cables and the bottom brackets, and whether the springs were checked on the same visit.
Our methodology says parts drive most of the difference between jobs. A Michigan company's own published cable price follows the estimate, and it falls inside our range. Wages are pay, not price.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $115 to $350 per repair | Built from two national published ranges, adjusted by the Michigan garage door technician median wage ratio (0.94). Too few Michigan garage door companies publish a price to show a range, so none is shown. |
| Isabella Garage Door, Mt. Pleasant: cable replacement, as the company publishes it | $160 to $200 | Read on the company's own pricing page on Oct 19, 2026. One company's price, not a Michigan range and not a quote. The company says the price varies with door size and cable type. |
| Michigan median hourly wage, mechanical door repairers | $25.18 an hour | Nearest BLS code (49-9011, mechanical door repairers), read through O*NET OnLine. Pay, not price. |
| Michigan 25th to 75th percentile hourly wage | $21.73 to $33.03 an hour | Pay, not price. |
| Michigan median annual wage | $52,370 a year | Pay, not price. |
| Detroit-Warren-Dearborn median hourly wage | $24.12 an hour | Pay, not price. |
| Grand Rapids-Wyoming-Kentwood median hourly wage | $28.65 an hour | Pay, not price. |
| Kalamazoo-Portage median hourly wage | $29.42 an hour | Pay, not price. |
| Lansing-East Lansing median hourly wage | $30.96 an hour | Pay, not price. |
| United States median hourly wage, same occupation | $26.79 an hour | Same occupation, national, comparison only. Pay, not price. |
How we estimate costs: the Estimated range row is a model, not a quote. It takes two published national ranges for this job (cost guides from third-party sites that we have not verified and do not cite) and multiplies them by Michigan's garage door technician median wage ratio to the US (0.94, BLS May 2025 data read through O*NET OnLine, using mechanical door repairers as the nearest occupation). The wage rows in the table are what that occupation is paid, which is not a price. Where a Michigan company publishes a price, it only keeps the low end of the range from sitting above it. We have not collected quotes, and only two Michigan garage door companies published a regular dollar price we could count, so no range of Michigan prices is shown. A real quote can land outside the range. Full method. Prices as of Oct 19, 2026.
What the cables do, and who does the repair
On a sectional door a cable runs from a bracket at each bottom corner of the door up to the lift system, which is a drum on a torsion shaft or a pulley on an extension system. The springs supply the lifting force and the cables carry it to the door, so a cable that fails leaves the door either hanging from one side or without its lift.
We hold no source for what a cable repair includes, so we do not list its steps. What we can source is who does it: DASMA says the bottom brackets are connected to the springs and under extreme tension, and that they should be adjusted or loosened only by a trained door systems technician.
Do it yourself or call a company
Pro job. DASMA says that, because of the high spring tension, cables should be replaced only by a trained technician. The federal opener rule's required instructions say the same thing differently: have a qualified service person make repairs to cables, spring assemblies and other hardware. We found no source that makes a homeowner cable replacement safe, so we do not describe how to do one.
What to ask before the technician starts
Ask if the estimate covers both cables or only one, if the springs are checked at the same visit, and if the bottom brackets and drums are included. Ask for the parts and the labor to be written separately. If the company says it holds a license, ask for the number and check it on LARA's license lookup. As far as we can tell from LARA's list of licensed professions, Michigan has no garage door license of its own. A residential builder license may apply to this work; we could not settle that from LARA or the statute, and we assert neither way. LARA's Residential Builders section, 517-241-9309, is the place to ask.
For paperwork, LARA says never to pay for the entire job in advance, to pay by check to the company name and to get a receipt. The Construction Lien Act says a contractor has no construction lien on a residential structure without a written contract, and that the contract must state the license requirement and the license number where one is required.
Cable problems that cannot wait
- A cable is hanging loose or the door sits crooked, and a car or person is inside the garage.
- The door will not hold, or drops when released.
- The property is open and unsecured overnight.
- A cable that looks worn on a door that still works: stop using the door, photograph it from a distance and book a visit.
- Wanting the cables looked at during the annual visit DASMA recommends from a trained door systems technician.
What to do before you call
- Keep people, pets and vehicles clear of the door and do not try to lift it.
- Unplug the opener or switch it off at the breaker.
- Photograph the cable, the bottom corners and the door's tilt from a safe distance.
- Note which side is lower and whether you heard a bang.
- Write down the door's width and when you first noticed the fault.
Permit position for cable work
A permit for a cable repair is not addressed in any Michigan source we can cite. State law requires one for the construction or alteration of a building unless the act or the code excepts it, and the local building department decides how that applies to a repair of this kind. Ask your city's building department. Claims that no permit is ever needed, or that one is always needed, have no state source behind them.
Ask the company for its legal name and, if it says it holds a license, the license number, and check that number with the agency that issued it before any work starts.

A tool for this job
Garage door symptom checker
Two questions: is anyone or anything trapped, and what is the door doing. You get what the symptom points to, a plain verdict, either safe to look at yourself or a job for a trained technician, and what we can say about cost. The verdicts rest on the federal opener rule and the trade association's safety pages, and nothing here asks for your name.
Open the toolQuestions people ask
Can I replace a garage door cable myself?
DASMA says no: cables should be replaced only by a trained technician. The high spring tension behind them is the reason, and the federal opener rule's required instructions say to have a qualified service person repair cables and spring assemblies.
What does a frayed garage door cable mean?
DASMA says frayed or worn cables can break and cause injury, so stop using the door. Book a visit. DASMA advises looking at the cables from the floor up to the bottom brackets, which means looking, not touching.
Why are the bottom brackets dangerous?
DASMA says the bottom brackets are connected to the springs and under extreme tension. It says they should be adjusted or loosened only by a trained door systems technician. Leave them alone even if a bolt looks loose.
Should a technician check the springs when a cable breaks?
Ask for it: the cables and springs work together, and DASMA says older doors should have their springs inspected by a professional technician. If the door has two springs and one is replaced, DASMA says to replace both.
How much does garage door cable repair cost in Michigan?
Our estimate is $115 to $350 per repair, a model and not a collected Michigan price. National published ranges, adjusted for what Michigan garage door technicians are paid, sit behind it. Ask for an itemized written estimate.
