Farmington Hills particulars
Farmington Hills' 'When is a Permit Required' page lists 'Garage.' and 'Window and exterior door replacement.' among the cases that need a building permit. It does not name garage door replacement, so reading an overhead door into 'exterior door' is our inference, not the city's statement. Ask the Building Division at 31555 W. Eleven Mile Rd, 248-871-2450, which way it goes. On LARA's Statewide Jurisdiction List, enforcement sits with the city itself.
Farmington Hills has a median home value of $333,200, and 53.7 percent of its homes were built before 1980. An opener of any age still needs checking. If the door does not reverse promptly on an obstruction, the sensitivity may be set wrongly, which DASMA calls dangerous, and it recommends a trained door systems technician for that adjustment. DASMA says the wall button should be at least five feet above the floor.
For cold months, its technical sheet says a door in a climate of extreme heat or cold should be kept closed where possible and lubricating as the manufacturer directs. Pay a deposit as work begins and the balance as it progresses, not the whole job up front. The distance to Farmington is 1.7 miles.
Spring replacement in Farmington Hills: what to know
The required instructions for covered openers say: 'Have a qualified service person make repairs to cables, spring assemblies and other hardware.' Quote it to the company and ask who in the company meets that description. DASMA's own language is firmer still, saying spring systems are dangerous and should be repaired only by trained professionals, and that a second spring on a two-spring door should be replaced with the first.
The city's 'When is a Permit Required' page lists 'Garage.' and 'Window and exterior door replacement' among permit cases. It does not name a garage door spring, and treating an overhead door as an exterior door is our inference, so the Building Division at 31555 W. Eleven Mile Rd, 248-871-2450, has to confirm it. For labor context, the Detroit-Warren-Dearborn area reports a $24.12 median hourly wage for this occupation. A wage tells you what workers earn, not what the job costs.
Permits for spring replacement in Farmington Hills
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 Farmington Hills 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 the Building Division whether a spring replacement alone needs a permit and write down the name of the person who answers.
- 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 Farmington Hills 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.
