Troy particulars
Troy homes have a median value of $396,800, and 60.5 percent were built before 1980. DASMA says the wall button belongs at least five feet above the floor, out of reach of children, and the photo eyes no more than six inches above it. Measure both before you call anyone. The Building Department is at 500 W. Big Beaver Rd, 248-524-3300, with online permits through BSAonline. That detail comes from an earlier research pass on the city's page, so confirm it.
The Statewide Jurisdiction List says Troy enforces locally. We can cite no Troy wording on garage door permits, so ask the department if a replacement door or a new circuit needs a permit. If you are comparing insulated doors, remember DASMA's warning that R-value describes a section and U-factor the installed door, and that they cannot be swapped. DASMA's checklist for a finished job includes a tested reversing mechanism and torsion spring pads fastened to structural members.
LARA's $600 labor-and-materials line applies only to work that needs a license in the first place, so ask any company which license it says applies. Clawson sits 3.3 miles away.
Spring replacement in Troy: what to know
Spring work needs a trained technician under DASMA's guidance, and the federal instructions give the same direction: have a qualified service person make repairs to cables, spring assemblies and other hardware. A good estimate says which spring type your door has, how many are being replaced and whether cables and bottom brackets are being checked.
Troy's Building Department at 500 W. Big Beaver Rd handles permits, and the Statewide Jurisdiction List shows local enforcement. The office's address is on the city site, and we have its phone number only in secondhand material, so verify before calling. As far as Troy's pages go, they never name spring replacement. For scale, the median wage for mechanical door repairers in the Detroit-Warren-Dearborn area is $24.12 an hour; that is pay, not a quote.
Permits for spring replacement in Troy
No Michigan source we can cite answers the permit question for spring replacement.
Many cities run their own building department, so start by asking the City of Troy building department who issues garage door permits.
Spring problems that cannot wait
- The door will not lift and a car or person is inside the garage.
- The door falls, or drops when released.
- A cable is loose or hanging.
- The property is open and unsecured overnight.
- Wanting an inspection of an older door's springs. DASMA says older doors should have springs inspected by a professional technician.
What to do before you call
Try this first: ask for a written list of what the visit covers, naming each spring and cable.
- Keep clear of the door and do not try to lift it.
- Unplug the opener or switch it off.
- Photograph the spring and the opener label from a safe distance.
- Note if you see one spring or two.
- Try the spring life calculator if you know the spring's rated cycles; it is arithmetic, not a prediction.
What spring replacement costs
The estimate below is the Michigan-wide one, adjusted for Michigan wages and not for Troy in particular. The same table is on the spring replacement page. How we estimate costs. Prices as of Oct 19, 2026.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $155 to $330 per job, both springs | 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. |
| Estimated range for extension springs, not a quote | $95 to $215 per job, both extension springs | Built from one national published range, 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: spring replacement, as the company publishes it | $395 to $525 for a pair of springs; $325 to $395 for a single spring | Read on the company's own pricing page on Oct 19, 2026. One company's price, not a Michigan range and not a quote. Larger or heavy-duty doors need bigger springs and cost more, the company says. |

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.
Questions about spring replacement
Can I replace the spring on my garage door myself?
DASMA says no: spring systems are dangerous and should be repaired only by trained professionals. The federal rule's required instructions also say to have a qualified service person make repairs to cables and spring assemblies.
Can you replace just one spring on a garage door?
If the door has two springs, DASMA says to replace both, even if one is not broken. That prevents damage when the second breaks and keeps the door working efficiently.
Is it worth fixing a garage door spring?
A door with a broken spring is not safe to run, so the question is who repairs it and what you pay. DASMA says to use trained professionals. Ask for the repair price and a price for a new door on the same visit; our repair or replace tool lists the questions.
