AfterFast, Reliable Air Duct Repair Across Dunwoody
Air duct repair in Dunwoody typically runs $350 – $1,800 depending on whether we’re sealing a few failing joints or replacing whole runs of delaminated duct board. Our crews know the difference, because we’ve been inside hundreds of Georgetown, Dunwoody Club Forest, and Kingsley attics where 40-to-50-year-old ductwork is finally giving out. When you call (980) 447-2498, you’ll speak to a live person who can schedule a real inspection, not a call center script. We send the tech’s name and photo before arrival, and they’ll show a photo ID badge at your door before stepping inside.
Why Linden Air Duct Cleaning Is Dunwoody’s Preferred Air Duct Repair Company
Dunwoody homeowners don’t need a generic duct cleaner. They need someone who understands why a house built in 1974 on Dunwoody Club Drive fails differently than one built in 2004 in Alpharetta. Our Air Duct Repair team has spent enough hours in this city’s attics to predict what we’ll find before the ladder goes up. Original fiberglass duct board, crushed flex runs, separated plenum collars. We bring the replacement materials on the first trip because we’ve learned that’s what the job usually needs.
Every repair carries the 365-Day Done Right Promise in writing. If a covered repair doesn’t hold, we come back at no charge. That’s not a slogan. It’s printed on every job sheet. Marcus Veale, who leads our team, insists on it. The Threshold Standard also means every technician who walks through your door has passed a background check, carries photo ID, and arrives in a marked uniform. No subcontractors, no mystery crews.
We’ve served homeowners since 2004 as part of the Threshold Group family. The Dunwoody homeowners who call us back year after year tend to mention the same things: the written price before any work starts, the name-and-photo notice before the visit, and the fact that when they call at 6 a.m. or 11 p.m., a real person picks up.
Duct Replacement in Dunwoody
Duct Replacement in Dunwoody is often the only honest fix for homes where the original 1970s fiberglass duct board has delaminated beyond what sealing can save. We’re not talking about a cleaning. We’re talking about tearing out runs that have been quietly bleeding conditioned air into your attic for years and installing new flex or rigid duct that actually delivers air to your registers.
A typical full or partial duct replacement in Dunwoody runs $900 – $3,400 depending on how many runs have failed and how accessible your attic is. Ranches in Dunwoody Village with low-slope roofs and tight attic access usually cost more in labor than two-story colonials in Kingsley where the ductwork is spread across a wider, more open attic. We give you the written price before any work begins, and that number doesn’t change after we start pulling old duct.
What Replacement Actually Involves
We remove the failed duct board or collapsed flex, inspect the plenum and branch collars, then install new duct sized to your system’s actual airflow requirements. The old material leaves in sealed bags, not scattered across your attic floor. Before we close up, we seal every joint with mastic and verify the airflow at each register.
Mold and Biological Contamination
When delaminated duct board has been exposed to Dunwoody’s high summer humidity, it’s not unusual to find mold colonization inside the fiberglass itself. Replacement is the correct fix here, not encapsulation or spray sealant. Our techs use professional-grade equipment from Rotobrush and Abatement Technologies when source removal and HEPA filtration are required, and we document the before-and-after with photos so you can see exactly what was removed.
Ductwork Installation in Dunwoody
Ductwork Installation in Dunwoody usually comes up in two situations: a home addition or renovation that needs new supply and return runs, or a repair that has grown large enough that installing new duct is cheaper than patching the old. Either way, the job starts with a load calculation so the new duct actually fits your system’s fan capacity. Too many Dunwoody homes have ductwork that was undersized from the start.
New ductwork installation in Dunwoody typically runs $1,400 – $5,000 for a partial system, with full-home installation running higher depending on square footage and attic conditions. We’ll give you a written price for the entire job before we bring a single tool into your home. The price covers materials, labor, sealing, and cleanup.
Runs Sized for the Room, Not the Roofline
Original duct runs in Dunwoody’s 1968 – 1988 homes were sometimes routed based on what was easiest to frame, not what actually delivered balanced airflow. When we install new runs, we look at register placement, room size, and the distance from the air handler. The back bedroom off the hallway in a Georgetown ranch shouldn’t get half the airflow of the front living room simply because the original run was longer and kinked under attic insulation.
Sealing at the Air Handler
The plenum transition is where we find the most missed disconnects in Dunwoody. As duct board ages, the collar separates where it meets the air handler, and since Dunwoody’s oak and sweet gum pollen season forces more runtime, the leak worsens before anyone notices. New installs get mastic-sealed at every collar, not tape that dries and peels inside two Georgia summers.
Trusted Brands We Service in Dunwoody
We install and service ductwork across every major brand found in Dunwoody homes, and our vans carry the parts and materials local crews actually need in this city. That includes professional-grade equipment from Rotobrush and Nikro for cleaning and source removal, as well as air-quality products from Honeywell, Aprilaire, and Guardsman. For Dunwoody homeowners asking about filtration upgrades alongside a repair, we often recommend Aprilaire media filters given the pollen load this city’s tree canopy produces each spring. Stocking local parts means we’re not running back to a supply house across town while your attic stays open.
Common Air Duct Repair Problems We See in Dunwoody Homes
- Delaminated fiberglass duct board. Four decades of humidity cycling opens interior seams in original duct board, creating bypass gaps where conditioned air and biological contaminants leak into unconditioned attic spaces. This is the single most common repair call we run in Georgetown and Dunwoody Club Forest.
- Crushed or sagging flex duct. Original flex runs in 1970s and 1980s Dunwoody homes buckle under attic insulation after years of 140°F summer heat. The kink becomes a debris trap that chokes airflow to far registers and never clears with routine maintenance.
- Disconnected plenum collars. The metal collar or transition where ductwork meets the air handler separates as the surrounding duct board degrades. Given how much pollen forces Dunwoody systems to run each spring, this leak usually worsens for months before a homeowner notices the weak airflow.
- Biological growth inside ducts. Dunwoody’s high summer humidity, combined with unconditioned attic runs common to the area’s planned subdivisions, creates conditions where mold colonizes inside duct board and flex. If you smell mustiness only when the system runs, that’s often the cause.
Pricing for Air Duct Repair in Dunwoody, GA
A typical air duct repair in Dunwoody runs $350 – $1,800, with full duct replacement landing between $900 and $3,400 and new ductwork installation starting around $1,400. What moves the number: whether we’re sealing a failed joint or replacing a crushed flex run, how many runs are affected, and how accessible your attic is. A Dunwoody Village ranch with tight attic access will cost more in labor than a Kingsley two-story with an open attic. We give you a written price for the whole job before any work starts. No per-vent pricing, no bait-and-switch. Call (980) 447-2498 and we’ll give you a free estimate based on an actual inspection, not a guess over the phone.

FAQs About Air Duct Repair in Dunwoody
Dunwoody’s residential subdivisions like Georgetown, Dunwoody Club Forest, Kingsley, and Dunwoody Village were built out almost entirely between the late 1960s and mid-1980s. That means tens of thousands of homes in this city are running on original fiberglass duct board now 40 to 50 years old, actively delaminating from decades of humidity cycling. Alpharetta and Johns Creek have far newer housing stock, so their ductwork simply hasn’t aged long enough to fail from the inside out yet. Call (980) 447-2498 for an inspection if your home falls in that 1968 – 1988 build range.
In homes built between 1968 and 1988 in Dunwoody, a camera inspection most often reveals fiberglass duct board delaminating along interior seams, disconnected plenum collars at the air handler, crushed flex runs under attic insulation, and debris accumulation that has never been addressed. In Georgetown and Dunwoody Club Forest specifically, our techs stock flex-duct replacement materials on nearly every call because the failure pattern is that consistent. The inspection is what lets us give you a written repair price instead of an estimate guess.
We look at the duct board’s interior surface, the number of failed seams, and whether the fiberglass itself has absorbed moisture. If the damage is limited to a few joints or collars, sealing with mastic is the right fix. If the interior is delaminating along multiple seams or shows mold colonization inside the fiberglass, replacement is the honest answer. In Dunwoody’s older homes, we recommend replacement more often than sealing because the original material has reached the end of its service life. Either way, you get the written price before work starts.
Yes. Dunwoody’s city-designated heavy tree canopy, dominated by oak, sweet gum, and loblolly pine, concentrates spring pollen directly around residential air intakes. That pollen enters your ductwork, coats internal surfaces, and combines with Georgia’s summer humidity to create the conditions where biological growth takes hold inside unconditioned attic runs. It’s a structural and environmental double load that newer suburbs with fewer mature trees simply don’t face. A sealed, properly functioning duct system handles this better than one with bypass gaps pulling attic air through the same path as your supply air.
For Dunwoody homeowners dealing with heavy spring pollen, we typically recommend MERV 11 – 13 filtration paired with a properly sealed duct system. Anything higher on a standard residential blower can restrict airflow unless the system was designed for it, which most 1970s and 1980s air handlers were not. The filter only works if the air actually passes through it, so on a Dunwoody home with delaminated duct board and bypass gaps, sealing and repair comes first. After that, an Aprilaire media cabinet or a quality MERV 13 filter makes a real difference during pollen season.
