Why Fernbrook Garage Doors Alpharetta Is Dunwoody’s Preferred Garage Door Repair Company
Dunwoody homes are different from what you’ll find ten miles in any direction. The 1980s-era neighborhoods here, Dunwoody North and Kingsley among them, are full of original wood carriage doors that warp in Georgia humidity and jam in their tracks. Our team knows these doors because we’ve rebuilt dozens of them. We know the torsion spring inside a 1987 double door in Kingsley was under-spec’d from the factory, and we know the end bearing plates on those original installs bend before the cable snaps. That’s local knowledge you don’t get from a generic repair shop.
Jesse Calder set the standard for our technicians when Fernbrook joined the Cedarwell family of businesses in 2002: written price before any work starts, shoe covers on hardwood, drop cloths on tile, and a photo of the clean-up before the crew leaves. Every visit, no exceptions. That may sound like a small thing until a repair crew has walked through your kitchen in work boots. We protect the house, not just the door. Our Garage Door Repair team services all eight major brands, including Genie, Clopay, and Amarr, so parts are usually on the truck when we arrive.
Background-checked, uniformed technicians answer to one promise: the 365-Day Done Right Promise. If it’s not done right, we make it right. No negotiation, no follow-up invoice. That’s stamped on every job we complete in Dunwoody.
Styles & brands we work with
Garage Door Sensor Repair in Dunwoody
Garage door sensor repair in Dunwoody is common after summer thunderstorms, when wind-flex on wide double doors knocks the photo-eye sensors along the opener rail out of alignment. The sensors sit near the floor on each side of the door; if they can’t see each other, the opener refuses to close, or reverses mid-cycle. A sensor repair usually runs $120 – $320 depending on whether it’s a realignment, a wiring repair, or a full sensor replacement. On doors exposed to the south-facing sun and afternoon storm cells, we also see sensor housings warped by heat, which causes intermittent failures that are hard to reproduce.
If your door opens but won’t close, or reverses for no reason, call us before you force it. A door that reverses under load can strain the opener, and a sensor that’s been knocked loose can’t protect a child or pet from a closing door.
Sensor Alignment and Wiring Repairs
When a door takes a wind gust, the track can shift a quarter inch and throw the sensor beam off. We realign the sensors, secure the brackets, and check the wiring where it runs along the track. Most alignment jobs in Dunwoody take under an hour.
Full Sensor Replacement
Older sensors on 1970s and 1980s openers in Dunwoody often fail because of corroded connectors or cracked lenses from sun exposure. Replacement sensors are straightforward to install, and we test them with a full open-and-close cycle before we leave, plus a block test at the beam.
Emergency Garage Door Repair in Dunwoody
Emergency garage door repair in Dunwoody usually means a spring snapped while the door was mid-cycle, leaving a 200- to 300-pound door hanging on one cable or resting against the opener rail. We respond to these calls the same day, and often within a few hours, because a half-open garage in Dunwoody is a liability: it invites heat, humidity, pests, and anyone walking by. A snapped torsion spring repair runs $180 – $340, and we carry high-cycle replacement springs rated for 25,000 cycles, which is a meaningful upgrade over the original 10,000-cycle springs found in most 1980s Dunwoody doors.
If the door is stuck open, don’t try to force it down. Disconnect the opener, leave the door where it is, and call (229) 471-5755. We’ll talk you through securing the space until a technician arrives.
Post-Storm Door and Track Damage
High-wind thunderstorms that roll through Dunwoody in July and August flex wide double doors, knocking track alignment out and stressing photo-eye sensors on the opener rail. After a strong storm, check that your door still sits flush in the opening and that it moves smoothly. A door that scrapes or shudders may be partially off-track, and running it further scores the rollers and bends the track brackets.
High-Cycle Spring Upgrades
Original extension springs on 1970s through 1990s Dunwoody homes have typically exceeded their 10,000-cycle lifespan, meaning they fail without warning. We recommend converting older extension spring systems to torsion springs with a 25,000-cycle rating, especially on doors used multiple times a day by commuters heading to Perimeter Center and MARTA.
Trusted Brands We Service in Dunwoody
Our technicians train on eight major brands: LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor. For Dunwoody homeowners, that matters most when you have a Genie opener from 2003 or an Amarr door original to the house and the manufacturer has discontinued the part. We keep common replacement parts on the truck, and we can order from local suppliers in the metro area, so most repairs in Dunwoody are completed in a single visit. If your door carries a Clopay or Wayne Dalton badge, we know the weight and balance specs well enough to tune the springs correctly the first time.

AfterCommon Garage Door Repair Problems We See in Dunwoody Homes
- Humidity-warped wooden doors binding in tracks. Original 1980s wood carriage doors in Dunwoody North and Kingsley swell in Georgia’s summer humidity, and the door edges scrape against the track until something gives. We add bottom weather seals, shave binding edges, and reinforce the frame so the door doesn’t jam again.
- Broken torsion springs on double-wide doors. A 250-pound wood door puts twice the fatigue on its spring as a modern insulated steel door. When the spring snaps, the door drops hard, often bending the opener rail or end bearing plates in the process.
- Track and sensor damage after storm season. Wind gusts flex the door while it’s closed, and over time that flex knocks the track brackets loose and stresses the photo-eye sensor mounts. We see a spike in track realignment calls in Dunwoody every August.
- Worn rollers on 1990s-era doors. Original steel rollers without bearings grind against the track and wear flat spots, making the door loud and jerky. Replacing them with nylon or sealed-bearing rollers quiets the operation, which matters when there’s a nursery above the garage.

FAQs About Garage Door Repair in Dunwoody
A wind-rated door is built to resist the pressure differential from high wind, while an impact-rated door is also tested to take a flying branch or debris strike without puncturing. You can check the door’s label for a wind-load rating sticker, typically on the inside of the door panel near a corner, but the short answer for most Dunwoody homes is that an original 1980s wood door was never rated for today’s storm codes. If you’re in a home built before 2000, the door almost certainly doesn’t meet current wind-rating standards. We can inspect the door, measure the panels and track, and tell you honestly whether reinforcing or replacing is the right call. Call (229) 471-5755 for a free evaluation.
We repair these doors all the time, and the answer depends on the door’s structural condition. If the wood is solid but swollen, we can shave the edges, rebuild the spring system, and add a bottom seal to keep moisture out, which usually runs under $500. If the panels are rotting, delaminating, or the frame is pulling apart, replacement with an insulated steel or composite door is the better long-term answer, and a new door in Dunwoody typically runs $700 – $2,200 installed. We’ll give you a written price for both options and walk you through the tradeoff. No obligation.
A torsion spring sits on a shaft above the closed door and winds and unwinds under torque; an extension spring hangs along the track on either side and stretches as the door lowers. Most Dunwoody homes built from the 1970s through early 1990s use extension springs, which fail more abruptly and with less warning. Torsion springs are safer, quieter, and last longer, and we commonly convert older Dunwoody doors to torsion systems when the original springs fail. We’ll show you what you have and give you the exact conversion price before any work begins.
We answer the phone 24/7, and for a door that won’t close or is hanging after a storm, we dispatch to Dunwoody the same day. Most emergency calls in the Dunwoody area get a technician on site the same afternoon or evening. If your door is stuck open, tell the person on the phone that’s the situation and we’ll prioritize it. Call (229) 471-5755 and a live person will answer, no voicemail tree.
Replacing a garage door with a like-for-like door in the same opening typically does not require a permit in Dunwoody, but adding structural reinforcement or changing the opening dimensions can trigger a permit review. We handle that determination for you: our technicians know the current Dunwoody code requirements for wind-rated doors and will tell you during the estimate whether the city needs to sign off, and we’ll prepare the paperwork if it does.
