Why Brock Garage Door Repair Is Dunwoody’s Preferred Garage Door Cable Repair Company
Dunwoody homeowners call us because they’ve been through the other kind of repair company before: the one that quotes a number on the phone, then adds charges at the door. We don’t work that way. Brock Garage Door Repair is an independently owned and operated location within the Garrison Partners network, and every job runs to The Garrison Standard. For you that means a written price before any work starts, a uniformed tech who’s passed a background check, and a 365-Day Done Right Promise in writing on every repair.
Wade Mercer leads our operation, and he’s built the crew around one idea: show up in the window, do the job by the book, leave the site clean, and stand behind the work for a full year. Our Garage Door Cable Repair team services systems from LiftMaster, Chamberlain, Genie, and Clopay. When a cable goes in Dunwoody, we don’t just swap the part and leave. We check why it failed.
Garage Door Cable Replacement in Dunwoody
Garage Door Cable Replacement in Dunwoody means pulling the old cable off the drum, fitting a new one sized to your door and spring system, and re-tensioning the assembly so the door lifts level. Most jobs run $130 – $250. A cable on a Dunwoody door rarely fails on its own. It frays because something else has changed: a track out of alignment, a worn drum, or a spring that’s lost its tension and is now asking the cable to carry weight it was never meant to hold.
When replacement is the right call
If the cable has snapped, replacement isn’t a choice, it’s the repair. If it’s frayed but still holding, replacing both cables at the same time prevents a second failure weeks later. We always replace cables in pairs because the unbroken one has seen the same wear.
What gets checked on every cable job
Before we button anything up, we inspect the torsion spring, the drums, the end bearing plates, and the track alignment. On Dunwoody doors we also clear pollen and leaf tannins out of the hinges and rollers when they’re causing extra drag. That’s the difference between fixing the symptom and fixing the door.
Garage Door Track Repair in Dunwoody
Garage Door Track Repair in Dunwoody happens more often than homeowners expect, and the culprit is usually under the driveway rather than above it. Dunwoody sits on red clay that expands after heavy spring rains. When the soil shifts, the slab moves a fraction of an inch, and that’s enough to throw a track out of plumb. The door then rides with a side-load on the cables, which is exactly how a good cable frays and snaps months later. Track realignment runs $120 – $240.
Re-shimming versus replacement
Most Dunwoody tracks don’t need to be replaced. They need to be re-shimmed. We pull the track back into alignment, add shims where the slab has settled, and re-torque the brackets. Then we cycle the door a few times to verify the cable spools evenly on both drums.
Heavy doors and track wear
Steel carriage-house doors built in the 1990s and 2000s are common in Dunwoody Club Forest and the Mount Vernon area. Those doors are heavier than the wood originals they replaced, and that weight works against the track and hardware every single cycle. We run a full track check on every cable call, not just a visual glance.
Trusted Brands We Service in Dunwoody
We service LiftMaster, Chamberlain, Genie, and Clopay systems across Dunwoody every week. Our techs are trained on eight major brands, so when your LiftMaster opener is straining against a heavy steel door, the fix is matched to your specific system rather than a generic workaround. Because we work these same doors throughout Dunwoody, our trucks carry the common cable and drum parts for local setups, which means faster turnaround when yours fails. No waiting on a second trip from a parts warehouse.
Common Garage Door Cable Repair Problems We See in Dunwoody Homes
- Red clay shift after wet springs. Dunwoody’s soil expands and contracts with rainfall, moving slabs enough to pull tracks out of alignment. The cable then rubs and frays at the drum, and one day it lets go.
- Pollen and leaf tannins in the track assembly. Dunwoody’s heavy tree canopy drops debris that coats rollers and hinges. The grinding paste from spring pollen accelerates wear on the entire system, including the cables.
- 20-plus-year-old steel doors hitting their first major cycle. Original 1990s carriage-house doors in subdivisions around Mount Vernon and Dunwoody Club Forest are now past their first cable and spring lifespan. Heavier doors mean more stress on every component.
- Low limbs dropping debris into the door path. Dunwoody’s Tree Preservation Ordinance protects mature trees, which means limbs over the driveway often can’t be removed. The debris they drop jams the sectional path and stresses cables on every cycle.

FAQs About Garage Door Cable Repair in Dunwoody
Dunwoody’s red clay soil expands when saturated, which shifts the slab under the door and knocks the track out of alignment. The door then rides with a side-load on the cables, fraying them at the drum until one snaps. If your cable failed after a wet stretch, we check track alignment on the same visit. Call (254) 602-5116 and we’ll inspect it, usually same day.
Straining on a heavy steel door often means the cables aren’t carrying their share of the load anymore, usually because one has stretched or the track is binding. We inspect the cable tension at the drum first, then the track and spring. The cable itself may be fine, but that’s exactly what the visit is for. Call (254) 602-5116 for a written diagnosis before any work starts.
Yes. Because Dunwoody’s soil movement is a known issue here, every cable repair includes a track alignment check. If the track is out of plumb, we re-shim it during the same visit. The price covers the work we agree on before we start. Call (254) 602-5116 and we’ll tell you what we found and what it costs to fix.
Spring pollen and leaf tannins from Dunwoody’s mature trees coat the rollers and hinges, adding drag to the door’s travel. The extra resistance loads the cables and opener every time the door cycles. Low limbs the city’s Tree Preservation Ordinance protects can also drop debris into the door’s path, jamming the sectional panels. We clear that debris as part of our cable service. Call (254) 602-5116 for a full inspection.
Ask whether the spring, drums, and end bearing plates are also at the end of their lifespan. On a 20-plus-year-old door, replacing only the cables often means another failure within months. We’ll show you the wear on every component and give you a written price for the full fix. Call (254) 602-5116 and we’ll walk you through what the door actually needs.
Call Brock Garage Door Repair in Dunwoody
We got a call from a homeowner off Mount Vernon Road whose 1990s steel carriage-house sectional door had a snapped cable on one side. The door was hanging crooked and the opener was straining. We replaced both cables, inspected the torsion spring and drums, then re-shimmed the track alignment because the red clay under the driveway had shifted after a wet week. The door balanced cleanly, the LiftMaster opener stopped working overtime, and we cleared pollen and leaf tannins out of the hinges and rollers before we left. That’s the job done right, one trip, in writing.
