We’ve been working Atlanta homes since 1984, and there’s no duct problem in this city we haven’t seen twice. From the 1950s ranches of Ormewood Park and East Atlanta with their original galvanized trunk lines rusting through damp crawl spaces, to the 1990s two-stories of Gwinnett and Forsyth counties with flex-duct sagging in 140-degree attics, our Duct Repair & Sealing team knows what Atlanta’s climate and housing stock do to ductwork over decades. We don’t guess. We camera-inspect every system before and after, show you what we found, and quote one honest price before starting.
Why Bellows Air Duct & Vent Co. of Atlanta Is Atlanta’s Preferred Duct Repair & Sealing Company
Forty-two years in this market means something. We’ve repaired ducts in the same Druid Hills homes three times across three owners, and those homeowners keep our number because the job stays done. Our 90-Day Done Right Promise is stamped on every invoice: if it’s not right, we return at no charge, no paperwork, no arguing. That promise has been non-negotiable since Cliff Darden founded Bellows in 1984.
Calls to our Atlanta office reach a live person 24 hours a day, not a voicemail tree. Our technicians are background-checked, uniformed, and equipped with Rotobrush and Nikro professional-grade systems, the same brands serious HVAC contractors specify. Most repairs complete in one visit. We show up when we say we will. And the price we quote on the phone is the price on the invoice, period.
We understand Atlanta’s dual housing reality: the intown mid-century stock with metal ducts in crawl spaces, and the suburban build-out with flex-duct in attics. That local knowledge saves our customers money because we diagnose correctly the first time instead of treating every system the same.
Our Duct Repair & Sealing Services in Atlanta
Mastic Sealant Application
Atlanta’s humidity destroys duct tape. We’ve opened too many crawl spaces in Virginia-Highland and Kirkwood to find repairs that failed within a year because someone used cloth-backed tape instead of proper mastic. A typical mastic sealant application in Atlanta runs $180-$340 for accessible trunk lines, and it lasts because we use water-based UL 181-rated mastic rated for Georgia’s moisture load. We brush or trowel it onto joints, seams, and connections, then verify with a pressure test before we leave.
Metal Duct Repair
Galvanized sheet-metal ducts in Atlanta’s older homes don’t fail all at once. They rust through at joints first, where condensation collects against red-clay crawl-space floors. We recently repaired a 1950s ranch in Ormewood Park where the original galvanized trunk line had rusted through at a joint, dumping debris into the living room. We cut out the corroded section, applied mastic sealant to the remaining metal, and reinstalled with a 26-gauge galvanized patch, restoring airflow without replacing the entire system. Metal duct repair in Atlanta typically ranges $350-$750 for localized patching, or $800-$1,400 if multiple trunk sections need replacement.
Flex Duct Repair
The flex-duct generation in Atlanta’s northern suburbs is now 20-30 years old, and Georgia’s attic temperatures have taken their toll. Sagging creates low spots where debris accumulates. Interior liner degradation produces a fiberglass dust that distributes through the house. We replace damaged flex runs with new R-8 insulated duct, properly support it to prevent future sagging, and seal every connection with mastic, not tape. Single flex-run replacement in Atlanta runs $220-$480 depending on attic accessibility.
Duct Insulation & Air Leak Repair
Unconditioned air leaking into Atlanta ductwork costs homeowners year-round because this city’s systems run almost continuously, cooling from April through October and heating through winter. We pressure-test the entire system, locate leaks with smoke pencils and thermal imaging, then seal and reinsulate. Air leak repair with spot insulation typically runs $280-$550. For systems with widespread insulation failure in unconditioned attics, full rewrap runs $600-$1,100.

Common Duct Repair & Sealing Problems We See in Atlanta Homes
- Galvanized ducts in crawl spaces rust from decades of moisture, creating holes that leak conditioned air and suck in pollen-laden outside air. We find this constantly in intown neighborhoods like East Atlanta and Ormewood Park, where 1950s-60s ranches still run original metal through damp, red-clay crawl spaces.
- Flex-ducts in attics sag from Atlanta’s extreme heat, forming low spots where debris accumulates and restricts airflow. The 1990s-2000s suburban build-out across Gwinnett and Cherokee counties is hitting this wall now as that flex-duct ages.
- Improper sealing with duct tape fails within a year in Atlanta’s humidity, undoing all repair work. We’ve re-repaired too many jobs where someone took a shortcut. Mastic is the only sealant that holds up in this climate.
- Spring pollen surges overload compromised duct systems. When pine pollen peaks in March and April, coating cars across Buckhead and Midtown, damaged ducts pull that concentration directly into air handlers and distribute it through the house. Sealed, intact ductwork is your first defense.

FAQs - Duct Repair & Sealing in Atlanta
Atlanta’s humidity destroys standard duct tape within 6-12 months by breaking down its adhesive and cloth backing. We use only water-based UL 181-rated mastic sealant, which remains flexible and bonded in sustained moisture. Every repair we complete is pressure-tested before we leave. Call (855) 305-5564 for a free inspection of any previous repair you’re unsure about.
Localized rust-through at joints is worth repairing with galvanized patches and mastic, typically $350-$750. If the trunk line has widespread corrosion or multiple failure points, replacement becomes more economical long-term. We camera-inspect to show you the extent before you decide. Our Ormewood Park job is a good example: one rusted joint, patched and sealed, and that system is still running three years later. Call for an honest assessment.
Flex-duct leaks recur because tape fails in Atlanta’s attic heat, or because sagging creates new separations at connections. Proper repair requires mastic at every joint, adequate support straps to prevent sag, and sometimes replacement of degraded liner material. We fix the cause, not just the symptom. Free estimates at (855) 305-5564.
Hidden duct leaks waste 20-30% of conditioned air in typical Atlanta homes, according to Department of Energy estimates. You pay for that waste in higher utility bills even when comfort seems acceptable. Our $89 seasonal tune-up includes a basic leak check. Or schedule a camera inspection if your home is 20+ years old and has never had ductwork evaluated.
Atlanta’s dense urban tree canopy, the “city in a forest,” produces pollen loads among the nation’s highest. Compromised ductwork pulls that pollen directly into your system and distributes it through the house. Sealed ducts are your primary barrier. We see the worst indoor air quality in homes with rust holes or failed seals, especially during March and April when pine pollen peaks. Proper sealing and repair reduce that load significantly. Call (855) 305-5564 for a free estimate.
