Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable Air Duct Repair Across Roswell
If the ductwork in your Roswell home is 25 to 40 years old, there’s a good chance it’s quietly failing in the attic. We see disconnected flex runs, crushed sections, and deteriorating fiberglass lining in Roswell homes built between 1983 and 2000 more than in almost any other part of metro Atlanta. Repairing those problems typically costs $450 to $1,800 for a single-day job depending on how much of the duct system has to be sealed, replaced, or reconnected, and our Air Duct Repair team does this work right the first time. Call (980) 447-2498 and we’ll send a background-checked, photo-badged technician to your door.
Nobody should have to guess whether the air their family is breathing has been pulled through a disconnected duct in a 130-degree attic. We’ll put a camera in your ducts and show you exactly what we find before we quote a single dollar.
Why Linden Air Duct Cleaning Is Roswell’s Preferred Air Duct Repair Company
Roswell homeowners call us because the problems in their ductwork are rarely what a generic duct-cleaning coupon company is prepared to fix. We walk into homes off Holcomb Bridge Road, Hardscrabble Road, and east of Roswell Road and find the same things: older flex duct that has pulled loose at the trunk-line collars, collapsed runs under attic insulation, and fiberglass liner that’s breaking down after three or four decades of Georgia Piedmont heat. None of that gets solved by a $79 special. It gets solved by a technician who can actually seal and replace ductwork while you watch the before-and-after photos on arrival.
We’re part of the Threshold Group family, serving homeowners since 2004, and we hold every technician to what we call the Threshold Standard. That means the person who comes to your Roswell home is background-checked, identity-verified, arrives in a clean marked uniform, and carries a photo ID badge they present at the door. Before the visit, you get the technician’s name and photo sent to your phone. You’ll know who’s walking up your driveway before they ring the bell.
The price you’re quoted is the price you pay. We put it in writing before any work begins, every single time, no exceptions. And every repair we make carries a written guarantee. If a covered repair fails within 365 days, we come back and make it right at no charge. That’s not a promotion. It’s how we’ve worked since 2004.
Duct Replacement in Roswell
Duct Replacement in Roswell usually means removing and disposing of old flexible duct runs that have collapsed, torn, or become so brittle from attic heat that sealing them isn’t worth the trouble. We see this all the time in two-story Colonials east of Roswell Road, where 1980s and 1990s builders ran long stretches of flex duct through unconditioned attics that hit 130 degrees or more every summer. A typical partial replacement for two or three disconnected runs in Roswell runs $650 to $1,400, while a full flex-duct replacement in a 3,500 to 5,000 square foot home runs $2,800 to $6,500.
Rip-and-Replace in Attic Spaces
Most Roswell replacement work happens in the attic, where original flex duct has been baking for decades. We remove the old material, install new R-6 or R-8 flex, and seal every connection with mastic, not tape. Tape dries and fails. Mastic stays flexible and keeps air where it’s supposed to be.
When Patching Isn’t Enough
If a single run is disconnected and the rest of the system tests fine, you don’t need a full replacement. We’ll tell you that plainly. We recommend replacement when runs are crushed under insulation, the inner liner has torn across multiple sections, or mold is present inside the duct wall and can’t be removed by cleaning alone.
Ductwork Installation in Roswell
Ductwork Installation in Roswell comes up when a homeowner has added a room, finished a basement, or discovered that part of the original system was never sized or sealed properly in the first place. We design and install new duct runs, return drops, and supply registers to match the existing HVAC system’s static pressure. New ductwork installation in Roswell typically ranges from $1,200 to $4,800 for a room addition or partial system, and $6,000 to $12,000 for a full-system install in a large two-story home.
New Runs for Added Square Footage
If you finished a basement or converted a garage in your Roswell home, the original duct plan probably doesn’t cover that space. We’ll calculate air volume needs and run properly sized flex or rigid duct from the main trunk to the new registers, sealed tight at every joint.
Sealing and Pressure Balancing
Sometimes the real fix in a Roswell home isn’t new duct at all. It’s sealing the connections that have loosened over 30 years so the system’s static pressure returns to spec. We measure airflow before and after so you can see the difference in black and white.
Trusted Brands We Service in Roswell
Our Roswell technicians carry parts and materials compatible with the equipment most homes in this area already have. We run Rotobrush negative-pressure extraction systems for source removal, and we install or integrate filtration products from Aprilaire and Abatement Technologies where an older Roswell system needs better particle control. Because we stock common flex duct sizes, collars, mastic, and plenum components on our trucks, most repair jobs in Roswell are completed in a single visit without waiting on a parts run back to the Atlanta office.
Common Air Duct Repair Problems We See in Roswell Homes
- Disconnected flex at trunk-line collars. In subdivisions east of Roswell Road built between 1987 and 1998, it’s common to find flex duct that has pulled loose where it connects to the main trunk. The system keeps running, pulling 130-degree attic air and spring pollen directly into the supply side for years without the homeowner knowing.
- Degraded fiberglass liner shedding into registers. Original ductwork from the 1980s and early 1990s is now 25 to 40 years old. The inner fiberglass liner breaks down and sends dust, glass fibers, and debris out through your registers and into the air handler.
- Condensation and microbial growth at crawlspace transitions. The Chattahoochee River’s humidity and Roswell’s piedmont climate mean attics and crawlspaces stay damp. Flex duct running through unconditioned crawlspaces, or transitioning from attic to crawlspace, collects condensation that feeds mold and mildew inside the duct.
- Crushed runs under attic insulation. Homeowners storing boxes in attics or contractors blowing in new insulation routinely crush flex duct. The crushed section chokes airflow to a room or zone, and the system works harder to push air through a straw.
Pricing for Air Duct Repair in Roswell, GA
Here’s what we tell Roswell homeowners before we ever step foot in the attic. A single disconnected run that can be re-secured and sealed typically costs $300 to $500. Replacing a crushed section with new flex runs $450 to $900. A partial replacement covering two to three problem runs runs $650 to $1,400, and a full flex-duct replacement for a large two-story Roswell home runs $2,800 to $6,500 depending on square footage and the number of zones. The cost is driven by attic access, how much old material has to be removed, and whether we’re dealing with one disconnected run or systemic degradation across the whole system. You’ll see the price written down before we touch anything. Call (980) 447-2498 for a free estimate and we’ll give you an exact quote after a camera inspection.

FAQs About Air Duct Repair in Roswell
You won’t feel it. A disconnected run at the trunk-line collar rarely makes a sound you’d notice. What you’ll notice is an upstairs bedroom that never cools properly in July, a musty smell around the supply registers in one part of the house, or dust building up on surfaces within days of cleaning. The only way to know for certain is a camera inspection of the attic runs. In Roswell’s older subdivisions, we find detached flex duct often enough that we recommend a visual check during any cleaning or repair visit. Call (980) 447-2498 and we’ll show you the footage.
Not necessarily. Original flex duct from the 1990s is usually at the edge of its serviceable life, but if the liner is intact and the runs aren’t crushed, sealing and reconnection work can add years. What we look for is whether the inner liner has started to deteriorate or whether mold has taken hold inside the duct wall. If the liner is gone, no amount of sealing will save that run and replacement makes more financial sense than repeated repairs.
Because your Roswell home was built between 1983 and 2000, which means the original flex duct is now decades old and often compromised. Roswell’s dense tree canopy, recognized through its Tree City USA designation, puts enormous pollen loads into the air every spring, and when a duct run is disconnected or torn in the attic, that pollen gets pulled directly into your living spaces. Newer Alpharetta homes don’t have this duct vintage problem at the same scale. The fix is source removal: finding the disconnections, sealing them, and cleaning out what accumulated.
We put a camera into the attic runs, map the system, and find every failure point. Then we re-secure disconnected collars, replace crushed sections with new R-6 or R-8 flex, seal every joint with mastic, and measure static pressure at the air handler to confirm proper airflow. The job is done when the system holds pressure and the registers are moving the right air volume, not when the truck pulls away. You’ll see photos of your own attic before and after the work.
Can you repair just one disconnected duct run, or do I need a full replacement?
We repair a single run all the time, especially when a recent renovation or someone walking through the attic knocked a duct loose. If that’s all we find, you’ll pay for that one repair and nothing else. If the inspection shows multiple failing runs or liner breakdown across the system, we’ll show you the footage and give you a written quote for the full scope. You decide. The price is in writing before we start, whatever you choose.
