Our Garage Door Parts Services in Dunwoody
Torsion Spring Replacement
Torsion springs carry the full weight of your garage door. In Dunwoody’s 1970s-1990s subdivisions, the original springs are now 30-50 years old and corroding in metro Atlanta’s humid summers. We see clusters of failures in Dunwoody Club Forest and Georgetown, where entire streets were built with the same batch of builder-grade springs. When one snaps, neighbors often call within the same week. A typical torsion spring repair in Dunwoody runs $180-$340. We match the wire size, inside diameter, and length precisely, and we wind them to the correct number of turns for your door’s weight.
Extension Spring Replacement
Extension springs run along the horizontal tracks and are more common on older single-car garages and some one-piece doors still found in Dunwoody’s earlier neighborhoods. They are under extreme tension and can be dangerous to handle without training. We do not recommend homeowners attempt this work. Our technicians replace both springs as a matched set so the door lifts evenly, and we install safety cables to contain a broken spring. Most extension spring jobs in Dunwoody are finished in under two hours.
Cables & Drums
Cables lift the door and wrap around drums at the top of the shaft. In Dunwoody, we frequently find cables frayed from rubbing against misaligned tracks or drums grooved by decades of use. The rolling terrain around Dunwoody means many driveways slope, and doors on uneven openings wear cables unevenly. Cable repair in Dunwoody typically costs $130-$250. We inspect the drum condition before installing new cable, because a scored drum will chew through replacement cable in months.
Rollers & Hinges
Steel rollers on older Dunwoody doors grind flat spots into the track and create the shuddering noise neighbors can hear three houses down. Nylon rollers run quieter and do not require lubrication, but they must be sized correctly for the track radius. Hinge replacement matters too: a cracked hinge at the top section puts lateral stress on the entire door. Roller replacement in Dunwoody runs $110-$220 depending on count and type. We will tell you straight whether lubrication will buy you another season or if the roller is worn past saving.
Weatherstripping & Bottom Seal
Dunwoody’s ice storms are infrequent but severe. The January 2014 and February 2021 freezes left bottom seals frozen to concrete slabs across metro Atlanta, and Dunwoody’s sloped driveways made the problem worse. A torn seal lets humidity into the garage, accelerating spring corrosion and swelling unfinished wood panels. We stock bottom seals for standard 16-foot Clopay, Amarr, and Wayne Dalton doors common in Dunwoody’s subdivisions, and we measure on-site to ensure the correct bulb or bead profile.

Trusted Brands We Service in Dunwoody
We are factory-familiar with all major brands and carry common parts for LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor. For Dunwoody’s older housing stock, this matters because a 1991 Chamberlain chain-drive opener or a 1985 Genie screw-drive unit may need a discontinued part. When the component is no longer manufactured, we explain the retrofit options honestly and quote a new opener installation at $250-$550 if that is the smarter path. We do not chase parts for three weeks when a replacement makes more sense.
Common Garage Door Parts Problems We See in Dunwoody Homes
- Original torsion springs snapping in clusters. In Dunwoody Club Forest and Georgetown, entire blocks share identical springs from the 1980s. One cold snap in January and we are replacing three on the same street by Thursday.
- Chain-drive openers seizing from sprocket wear. The Chamberlain and Craftsman units installed in Dunwoody’s attached garages through the 1990s have run their design life. The sprocket strips, the chain binds, and the door stops mid-cycle.
- Bottom seals torn after ice events. Dunwoody’s freeze-thaw cycles and sloped driveways mean seals freeze to the slab. Forcing the open rips the rubber and leaves a gap that invites humidity and pests.
- Corroded cables and swollen wood panels from humidity. Metro Atlanta’s year-round moisture rusts cable fittings and causes older wooden sectional doors to rack out of square, binding in the tracks.

The Dunwoody Difference: Fix or Upgrade?
This is where our Dunwoody experience becomes useful. The city is split in two right now. On one side, you have the emergency calls: a 1987 torsion spring finally snapped, the Genie opener from 1985 died, the cable let go and the door is crooked in the frame. These are repair jobs. We fix them with the right parts and the door runs again.
On the other side, Dunwoody’s property values and school ratings have homeowners renovating rather than relocating. A carriage-style steel door with insulated panels and a quiet belt-drive LiftMaster is a common upgrade in the same neighborhoods where we just replaced a spring. We will tell you honestly when your hardware is past reliable repair and a new door installation at $700-$2,200 is the better long-term value. We will also tell you when a $220 roller replacement and tune-up will carry your original door another five years. That is the square deal.
We answered a call in Georgetown where a Chamberlain chain-drive opener from 1991 had seized mid-cycle, locking a Honda into a sloped driveway during a freeze. We replaced the corroded sprocket and springs, then upgraded the weather seal to prevent the bottom section from icing to the concrete again.

Our trucks run daily to Sandy Springs, Chamblee, Doraville, and Brookhaven. If you live near the border of Dunwoody and one of these cities, we will dispatch the closest available technician. Same pricing, same promise, same live person on the phone.

FAQs - Garage Door Parts in Dunwoody
Sometimes, but not always. Genie discontinued several screw-drive components from that era, and we do not chase obsolete parts for weeks when a new opener is the reliable solution. We will inspect the unit, check our supplier network, and give you an honest answer. If repair is possible, we quote it. If replacement makes more sense, we explain why and price a LiftMaster or Chamberlain installation at $250-$550. Call (855) 389-2471 and we will look at it.
Your subdivision was built with identical builder-grade torsion springs installed in bulk during the 1980s. They share the same wire gauge, cycle rating, and now the same corrosion and metal fatigue. When one snaps, the rest on your block are usually within a few hundred cycles of the same failure. We offer neighborhood inspections after a cluster break because catching the next one before it goes is cheaper than an emergency call. The inspection runs $89 during our seasonal tune-up special.
If the roller wheel is flat-spotted, cracked, or the bearing is grinding, lubrication is a temporary mask and replacement is the right call. If the roller is simply dry and the wheel is round, lubrication may buy you another year. We inspect each roller individually and tell you which ones need replacement and which do not. A full set of nylon rollers in Dunwoody typically runs $110-$220 installed. We do not sell you parts you do not need.
Yes. We stock bottom seals for the 16-foot Clopay doors common in Dunwoody’s 1975-1995 subdivisions, including the bulb-style and bead-style profiles. We measure the retainer channel on your door to confirm the correct seal type before installation. A new bottom seal prevents the humidity damage that warps wooden doors and corrodes springs. Most seal replacements are done in under thirty minutes.
Garage door spring replacement is generally considered maintenance and does not require a permit in Dunwoody. However, if your repair involves structural modification to the header, electrical work for a new opener circuit, or a full door replacement, permitting rules may apply. We handle the details on jobs where permits are needed and advise you on any that are not. For standard spring or cable replacement, we complete the work and you are done.
