Real Metro Detroit garage door work.

The questions below come straight from the calls and texts our dispatchers field every day from customers across Metro Detroit. They are written to help you make a good decision before you hire any garage door company — not just us.

The garage door industry in Southeast Michigan has more than its share of bad actors. Walk through any consumer-protection bulletin from the Michigan Attorney General's office or the Better Business Bureau's Metro Detroit chapter and you will find garage door repair consistently among the most-complained-about home services — usually right next to roofing contractors and tow-truck operators. The scams follow a pattern, and once you know the pattern, they are easy to avoid.

The single most important filter is insurance. Michigan does not license garage door work as a standalone trade, which means proof of general liability and workers' compensation insurance is the meaningful credential — it separates a real company with real employees from a guy with a ladder answering a lead-generation ad. A legitimate company produces a certificate of insurance on request, without drama, usually within the hour. It matters twice over: liability insurance covers your property if a job goes wrong (a dropped door, a cracked jamb, a bent opener rail), and workers' comp means an injured technician on your property is not your homeowner's policy's problem. BH Garage Door Metro Detroit is Licensed & Insured, and we encourage you to ask us — and everyone else you call — for the paperwork.

The second filter is the quoted price over the phone. Real garage door pricing is bounded — there are only so many ways a spring replacement, an opener install, or an off-track reset can play out, and a competent dispatcher can give you a tight flat-rate range from a one-minute description and a photo. If someone advertises a $29 service call with the explicit promise that the real cost will be "diagnosed on arrival," you are talking to a lead-aggregation operation, not a garage door company. The price will not be $29. The price will be whatever the commissioned salesman on your driveway thinks he can extract — and the industry's most notorious version of this ends with an $89 spring advertised and a $1,200 "full rebuild" invoiced. Walk away from these calls before the truck shows up; once it arrives, the pressure to pay something to make them leave is real, and they know it.

The third filter is the company's street presence and review pattern. Real garage door shops have a physical base that matches their service area, a long review history with photos and named technicians, and a phone number that, when you call it during normal business hours, is answered by a person who knows the trade. A company whose Google profile is a virtual office, whose reviews are all five stars from accounts that have reviewed nothing else, and whose phone routes to a national call center is — at best — a marketing operation flipping calls to subcontractors. The work might still get done, but the accountability is gone the moment a warranty claim comes up.

The fourth filter is diagnostic transparency. Ask the dispatcher what the technician will actually check. A real company will name the components: spring condition and cycle count, cable fray at the bottom brackets, roller wear, track alignment, door balance with the opener disengaged, opener force and travel settings, photo-eye alignment. A scam operation will dodge specifics or say "we'll see when we get there." And when the technician arrives, a legitimate diagnosis is demonstrable — a snapped spring has a visible gap, a frayed cable has visible broken strands, a worn roller wobbles in your hand. Ask to be shown every failed part before you approve its replacement. Honest techs love this question; the other kind changes the subject.

Pricing structure deserves one more paragraph. Honest garage door pricing is mostly flat-rate for the common jobs. A single torsion spring replacement has a flat number; a pair has a flat number; an off-track reset, a cable pair, a roller set, and each tier of opener install all have flat numbers. After-hours work has a disclosed surcharge, quoted on the call. None of these requires a technician on your driveway to discover what the work costs. The dispatcher should be able to give you the full price, in dollars, before any truck rolls. If they cannot, ask why — and consider that an answer in itself.

For commercial customers a slightly different filter applies. You want a company that can produce a one-page proposal with parts itemized by manufacturer and specification — spring cycle ratings, operator duty class, slat gauge for rolling steel — plus labor lines, warranty terms, and insurance certificates on company letterhead. The proposal should be signable as a purchase order or a small services agreement. If your vendor of choice cannot produce that document on request, they are an emergency-only contractor, and you need a different vendor for planned commercial work: dock-door replacements, high-cycle spring conversions, operator upgrades, multi-door maintenance contracts. The same company may be excellent at residential spring calls and unsuitable for a twelve-door logistics facility; those are different skill levels, and the marketplace rewards specialization. We do both — but we are honest about the difference, and we are happy to recommend other reputable Metro Detroit shops for the rare job outside our wheelhouse.

Warranties are the fifth filter and the one most customers forget to pin down. Garage door work has labor and parts warranties exactly like any other building trade. Reputable shops guarantee labor for at least a year against workmanship issues and pass through the manufacturer's warranty on hardware — typically 3–10 years on springs depending on cycle rating, 1–3 years on openers with lifetime coverage on some motors and belts, and up to lifetime on door sections from the major brands. Beware the inverted version: "lifetime warranty" pitches where the part is free forever but every replacement visit carries a fat labor charge. That structure incentivizes installing parts that fail. If a company cannot describe its warranty in plain language, or if "all sales final" appears anywhere on the invoice, that is a tell. Real shops back their work because they expect to be in business in five years and expect you to call them again.

If you apply all five filters — proof of insurance, transparent phone pricing, a real local presence with a real review pattern, demonstrable diagnostics, and written warranty terms — you will eliminate the vast majority of the bad actors before any truck arrives. The companies that pass all five filters are not all BH Garage Door Metro Detroit. There are other reputable garage door shops in Metro Detroit and we are happy to be compared to any of them. What we cannot do is win comparisons against $29 lead-generation ads, because the $29 is not a real number and the company behind it is not a real garage door shop. We hope this guide saves you from learning that the expensive way.

A short word on after-hours work. A meaningful share of garage door emergencies in Metro Detroit surface between 9pm and 7am — the spring that snaps in the evening cold, the door that will not close as the house goes to bed. The after-hours premium is one of the most-abused line items in the trade. Honest after-hours pricing reflects the real cost of paying a technician to be on call: typically twenty to forty percent more than the daytime rate, disclosed on the phone. It is not triple, and it is not an hourly meter that surprises you on the invoice. If you call at midnight and the dispatcher cannot quote the after-hours rate before sending a truck, the conversation should end there.

On springs specifically, because they are where the money and the danger concentrate: a torsion spring is specced by wire size, inside diameter, and length, matched to the measured weight of your door. A correct replacement restores the door to a state where you can lift it with two fingers with the opener disengaged. There is no such thing as a universal spring, and a company that installs without measuring is guessing with your door's balance. Ask what cycle rating is being installed — 10,000-cycle steel is standard, 25,000-plus is the upgrade worth having on a daily-use door — and ask whether the quote includes rebalancing and inspection of the cables and bearings that share the shaft. If the answer to any of this is vague, so is the company.

On openers: the drive types are chain (cheap, durable, loud), belt (quiet, the right answer for attached garages), and wall-mount jackshaft (premium, frees the ceiling, usually bundles battery backup). Horsepower matters less than the sales floor implies — an opener that struggles is almost always lifting an unbalanced door, and a bigger motor just masks the real problem until the gear strips. A proper install includes the rail, a reinforced header bracket, safety sensors at the correct height, force and travel calibration, remotes, keypad, and app setup. An opener quote that is dramatically cheaper than market usually excludes half of that list, and you find out on install day. Ask what is included, in writing.

On panel damage: a dented section does not automatically mean a new door. Most major brands sell replacement sections for years after a model ships, and a color- and profile-matched swap restores both appearance and structure for a fraction of full replacement. The honest exceptions are discontinued profiles, damage across multiple sections, and builder-grade doors where one section costs nearly half of a new door. A company that quotes only full replacement without discussing section availability is either not checking or not telling. Conversely, a company happy to bolt a mismatched panel onto your door and call it fixed is optimizing for the invoice, not the house. Both extremes are avoidable by asking one question: what are my options, and what would you do on your own house?

On maintenance: garage doors are machines with wear items, and the difference between a door that lasts thirty years and one that eats parts every winter is mostly lubrication, balance, and hardware tension — an hour of attention twice a year. A professional tune-up covers lubrication of springs, hinges, and rollers, a balance test, cable and roller inspection, hardware tightening, opener force calibration, and both federal safety tests. It is the cheapest service on any garage door company's menu and prevents the most expensive calls. If a company's only answer to every symptom is replacement, they are a sales organization; if their menu includes an honest tune-up, they are a service organization. Hire the second kind.

On door construction and what the spec sheet actually means: doors come single-layer (one steel skin), double-layer (skin plus foam board and backer), and triple-layer sandwich (steel–foam–steel). The sandwich construction with injected polyurethane is stiffer, quieter, better insulated (R-13 to R-18), and dramatically more dent-resistant — and in Michigan's climate it is the correct answer for any attached garage. R-value claims deserve scrutiny: some manufacturers quote the R-value of the foam at the panel's center rather than the door's real-world assembled performance. A knowledgeable dealer will tell you the difference without being asked. Gauge matters too — thicker steel skins (lower gauge numbers) resist dents and oil-canning. These details are exactly the kind of thing a real garage door company explains and a lead-reseller cannot.

On safety systems: every opener sold in the United States since 1993 is federally required (UL 325) to have photo-eye sensors and contact auto-reverse. These systems exist because doors killed and injured children before them. No legitimate technician will ever disable, bypass, or tape over a safety sensor to "fix" a door that will not close — the underlying cause is always diagnosable and fixable. When any company services your door, both systems should be tested before the truck leaves: a broom handle through the beam must reverse the closing door instantly, and a 2x4 flat on the floor must trigger the contact reverse. If a technician skips these tests, or worse, suggests defeating them, that tells you everything about the operation behind the truck.

On hardware sources: a real garage door company stocks springs, sections, and openers from wholesale distributors and passes through the manufacturer warranty. A scam operation carries whatever was cheapest — unbranded springs of unknown cycle rating, gray-market openers with no US warranty, aftermarket sections that almost match. Ask where the hardware comes from. Real inventory arrives in branded packaging with intact factory documentation and a warranty card. Springs with no markings and openers in plain brown boxes are a tell. The price difference between legitimate and gray-market hardware is small; the difference in what happens when it fails is not.

On the second opinion: if a technician on your driveway quotes a number that surprises you, you are allowed to send them away, pay only the disclosed service-call fee, and call another shop. Michigan consumer law does not require you to accept a quote just because the truck rolled. The first company may bill you for the trip — the disclosed diagnostic fee, not the inflated estimate — and that is the cost of a second opinion. It is almost always worth paying. On a four-figure "full rebuild" diagnosis, it is worth paying twice. Technicians who refuse to leave without payment of the full inflated estimate are crossing into criminal territory; if it happens to you, the non-emergency police line will help, and a written complaint to the Michigan Attorney General's consumer protection division is exactly the mechanism that gets these operations shut down.

On scope creep: a technician arrives for a broken spring, replaces it, then suggests new rollers, new cables, a new opener, and a full door replacement. Some of those suggestions may be legitimately useful — cables and springs do age together, and rollers are cheap to do while the door is being serviced. The honest way to handle it is for the technician to complete the original job at the quoted price, present the additional recommendations as a separate written estimate with no pressure, and leave. If the upsell becomes a condition — "I can't warranty the spring unless you also replace X" — that is manufactured leverage, and you are allowed to say no, pay the original amount, and end the visit. Document high-pressure interactions afterward in a short email to yourself; if you file a complaint later, the contemporaneous record matters.

Whether or not you end up hiring us, we hope you take this guide with you. The next time you need garage door work in Metro Detroit, ask the questions above. The trade is full of good people; you just have to know how to find them.

The garage door trade has its own vocabulary and most of it never makes it onto the invoice in a form a homeowner can understand. Here is a short, opinionated glossary of the terms we use most often on the phone and on the truck. If you are calling around for a quote, knowing these terms will make every conversation shorter and every estimate easier to compare.

Torsion spring — the tightly wound steel spring mounted on a shaft above the door that counterbalances the door's weight. When the door closes, the spring winds up and stores energy; when the door opens, the spring releases that energy through the cables so the opener (or your arm) only lifts a fraction of the true weight. A two-car steel door can weigh 150–300 lbs; a correctly specced torsion spring makes it feel like 10. When a torsion spring breaks you will see a clean two-inch gap in the coil — and the door becomes dead weight that neither you nor the opener should try to lift.

Extension springs — the older counterbalance style: a pair of long springs stretched alongside the horizontal tracks, one per side. They do the same job as a torsion spring but wear less evenly and, when they snap, they can whip — which is why every extension spring must have a safety cable threaded through it to contain the broken pieces. If your extension-spring door has no safety cables, that is a five-minute, must-do fix on the next service visit.

Cycle rating — the spring's life expectancy, measured in cycles (one open plus one close). Standard springs are rated for about 10,000 cycles — roughly 7–10 years at typical use, less if the garage is your front door. High-cycle springs (25,000–50,000) use thicker wire on a larger diameter and routinely last 15–20 years. When comparing spring quotes, the cycle rating is the number that makes one quote different from another — always ask for it.

Winding cone & winding bars — the cone is the fitting at the end of a torsion spring that a technician turns to load the spring with tension, using two solid-steel winding bars. This is the step that makes DIY spring work genuinely dangerous: the spring is wound under load a quarter-turn at a time, and a slipped or undersized bar releases that stored energy instantly. Vise-grips and screwdrivers are not winding bars, no matter what the video said.

Cable drum — the grooved aluminum wheel at each end of the torsion shaft that the lift cable winds onto as the door opens. Drums are matched pairs; a worn or cracked drum lets the cable ride out of its groove, which is a leading cause of crooked and off-track doors. When a tech "resets your cables," the drums are where the work happens.

Lift cables — the braided steel cables running from the bottom corners of the door up to the drums. They carry the door's full weight under spring tension. Cables fail by fraying at the bottom bracket where moisture and salt collect — a Michigan specialty — and they should always be replaced in pairs, because the survivor has the same mileage as the one that broke. Look, don't touch: a cable under tension is not a DIY item.

Bottom bracket — the steel bracket at each bottom corner of the door where the lift cable attaches. It is under direct spring tension at all times, which is why it usually carries a warning label. Removing a bottom bracket without first unloading the springs is one of the classic garage door injuries. If a bracket is rusted or bent, the fix is quick for a tech — and genuinely hazardous for anyone else.

Track — the steel channels the rollers travel in: vertical track up each side of the opening, a curved radius section, and horizontal track suspended from the ceiling. Track gets bent by car bumpers and ladder handles, and a bend as small as a quarter inch can throw a roller out and put the whole door on the floor of your garage. Track is repaired by straightening or replacing sections — it is not supposed to be "persuaded" with a hammer and left wavy.

Rollers — the wheels (on stems) that ride in the track, typically ten or more per door. Builder-grade steel rollers with no bearings are the #1 source of garage door noise in Metro Detroit. Sealed-bearing nylon rollers are the upgrade: dramatically quieter, no metal-on-metal wear, and they shrug off the freeze–thaw cycle. A full roller swap takes a tech under an hour and transforms how a door sounds.

Section / panel — the individual horizontal slabs that make up a sectional door, joined by hinges. "Panel" technically refers to the decorative rectangles embossed into a section, but in everyday use the words are swapped freely. The practical point: sections are individually replaceable on most major brands, which is why a dented section rarely requires a whole new door.

Sandwich construction — door sections built as steel–insulation–steel, with the foam core bonded to both skins. Compared with single-skin doors, sandwich sections are stiffer, quieter, warmer, and far more dent-resistant. Polyurethane (injected foam) beats polystyrene (cut board) on both insulation and rigidity. If you are buying one upgrade on a new Michigan door, buy this one.

R-value — the measure of a door's insulation, higher is better. Insulated residential doors run from about R-6 to R-18. In Metro Detroit an insulated door keeps an attached garage 10–20°F warmer in winter. One buyer's note: some brands advertise the R-value of the foam at the center of the panel rather than the assembled door's real performance — an honest dealer will volunteer the difference.

Headroom, backroom & side room — the three clearances that determine what hardware fits your garage: headroom is the space between the top of the opening and the ceiling, backroom is the depth from the opening to the back wall, side room is the wall space beside each jamb. Low-headroom garages (common in older Detroit and Ferndale homes) need special track kits; wall-mount openers need side room. This is why a real company measures before quoting a door.

Opener drive types — how the motor moves the trolley: chain drive (metal chain — cheap, durable, loud), belt drive (steel-reinforced rubber belt — quiet, the right answer for attached garages), screw drive (rotating threaded rod — mostly legacy units now), and wall-mount jackshaft (mounts beside the door and turns the torsion shaft directly — zero ceiling hardware, usually with battery backup and an automatic deadbolt).

Trolley & emergency release — the trolley is the carriage that connects the door arm to the opener's rail; the red cord hanging from it is the emergency release. Pulling the cord disconnects the door from the motor so you can lift it by hand during a power outage — safe only when the springs are intact. Rule of thumb: never pull the red cord while the door is up, because a door with a failed spring will fall.

Photo eyes — the two small sensors mounted about six inches off the floor on either side of the opening, shooting an infrared beam across the door's path. If anything breaks the beam, a closing door reverses instantly. When your door refuses to close and the opener light blinks, the photo eyes are the first suspect — blocked, dirty (road-salt film is a Michigan classic), knocked out of alignment, or washed out by low winter sun.

UL 325 — the federal safety standard that has governed openers since 1993. It is the reason every modern opener has photo eyes and contact auto-reverse (the door must reverse if it touches an obstruction — test it with a 2x4 flat on the floor). If your opener predates 1993, it predates both systems, and every honest company in the trade will recommend replacing it. Safety sensors are never to be bypassed, unplugged, or taped together — the cause of a non-closing door is always fixable.

Force & travel limits — the opener's calibration settings: travel limits define where "fully open" and "fully closed" are; force settings define how much resistance the opener tolerates before it assumes something is wrong and reverses. Michigan's seasonal swings genuinely change how much force a door needs (cold grease, stiff seals), which is why a door that behaved all summer starts phantom-reversing in January. Calibration is a five-minute fix — cranking the force to maximum is not a fix, it defeats a safety system.

Rolling code — the remote-control security scheme (LiftMaster's Security+ being the best known) where the radio code changes with every button press, so a captured code is useless. Standard on everything modern. If your opener is old enough to use a fixed code set by DIP switches, it is old enough to be opened by a $30 device — and old enough to replace.

myQ / Aladdin Connect — the Wi-Fi platforms from LiftMaster/Chamberlain and Genie respectively. They add smartphone control, open/close alerts, scheduled auto-close, and access history to an opener. Retrofit hubs bring the same features to most openers made after 1993. The feature customers thank us for most is the simplest: a notification that answers "did I close the garage?" forever.

Weather seal & retainer — the rubber gasket along the door's bottom edge (held by an aluminum retainer) plus the vinyl stop molding around the sides and top. Together they keep out snow, salt spray, leaves, and mice. In Michigan the bottom seal also freezes to the slab on wet winter nights — a stiff, cracked seal makes it worse. Seals are cheap and quick to replace, and it is the fall maintenance item most worth doing.

Off-track — the failure state where one or more rollers have left the track and the door is hanging crooked, usually caused by a frayed cable, a bumped track, or hitting the door with a vehicle. An off-track door can fall and should not be operated at all — not one more press of the button. A proper repair puts the door back, but more importantly finds and fixes whatever pushed it out in the first place.

That is the vocabulary that covers ninety-five percent of the conversations we have with Metro Detroit homeowners. If a technician on your driveway uses a term that is not on this list and cannot explain it in plain language when you ask — ask harder. Good techs love explaining this stuff. It is half the reason we wrote this page.
