AfterFast, Reliable Duct Repair & Sealing Across Roswell
Duct repair and sealing in Roswell typically costs $280-$720 for most residential jobs, with flex duct replacement running higher on large two-story homes. Most repairs are completed in a single visit, and every job starts with a written price before any work begins. Call (470) 495-9370 for a free estimate.
We’ve been driving to Roswell since 2013, and our crews know the difference between a 1980s colonial off Martin Road and a newer build near Holcomb Bridge. Dispatch and scheduling run from our Atlanta office, but the trucks that show up in Roswell carry Rotobrush and Nikro equipment, background-checked technicians in uniform, and the H.A.V.E.N. Standard in writing. We don’t subcontract. The person who quotes the job does the work.
Why CleanRun Air Duct Cleaning Atlanta Is Roswell’s Preferred Duct Repair & Sealing Company
Our Duct Repair & Sealing team has documented photo records from over 52,000 homes since 2013, including hundreds in Roswell’s 30075 and 30076 zip codes. Tomas Reyes, who leads CleanRun, personally reviews any callback under the 365-Day Done Right Promise. That promise is backed in writing on every job, not buried in a policy manual.
Roswell customers consistently mention the same things in their feedback: the technician showed the camera footage before mentioning a price, the written estimate matched the final invoice, and the before-and-after photos arrived by email the same evening. No per-vent math, no upsell once the van was in the driveway.
Response time to Roswell averages same-week scheduling, sometimes sooner depending on route density. We don’t promise same-day because duct repair is diagnostic work, not a rush job. What we do promise is Haven Standard Clause 1: a written price delivered before a single panel comes off, every time, with no exceptions.
We know which Roswell neighborhoods have the original flex duct runs in 140°F attics. We know the shared-stack condos near the river. That local knowledge changes what we bring on the truck and what we expect to find.
Our Duct Repair & Sealing Services in Roswell
Flex Duct Repair
Roswell’s housing stock is dominated by large traditional and colonial homes built during the 1980s-early 1990s suburban boom, most with multi-zone HVAC systems and long flex-duct runs in unconditioned attics. Georgia attic temperatures routinely exceed 140°F in summer. That heat shreds the inner liner of flex duct and loosens collar connections at supply boots.
On a Martins Landing job just off Martin Road, our tech camera-inspected a 1984 colonial’s attic flex runs and found the inner liner shredded by 140°F summer attic heat, with three supply-boot collars completely separated. We re-secured and mastic-sealed every collar, replaced the failed flex sections, then ran agitation tools and negative pressure through the supply and return ducts to source-remove the decades of pollen and mold spores. The homeowner noticed the second-floor rooms finally held temperature and the musty smell was gone.
Flex duct repair in Roswell typically runs $340-$580 for partial replacement of failed sections, or $680-$1,200 for full attic re-runs on large homes. We use Nikro equipment for negative-pressure extraction and Guardsman flex duct rated for Georgia attic conditions.
Duct Sealing with Mastic Sealant
Mastic sealant is the only duct sealing method we trust for Roswell’s climate. Tape dries and fails. Aerosol sealants don’t hold up to the thermal cycling in a 140°F attic. We brush-apply water-based mastic at every joint, collar, and plenum connection, then verify with a pressure test.
In river-corridor neighborhoods like Martins Landing, mastic sealing is often the critical repair. Original 1970s-80s flex duct has sagged mid-span and separated at supply-boot collars. Ducts here don’t just hold pollen and mold. They actively pull humid Chattahoochee-area attic air into the living space every time the air handler kicks on. Mastic re-separation at those collars stops the infiltration and restores designed airflow.
Mastic sealant application for a typical Roswell home runs $280-$450. Full system re-sealing on a large multi-zone house can reach $620-$890.
Metal Duct Repair
Roswell has fewer all-metal duct systems than older intown Atlanta neighborhoods, but we find them in ranch-style homes near the historic district and in some 1990s builds that used galvanized trunk lines with flex branches. Metal duct suffers from seam separation and rust at condensate points, especially where humid attic air contacts cool metal surfaces.
We repair metal duct with mechanical fastening and mastic overlay, not tape. For rusted sections, we cut out and replace with new galvanized or switch to insulated flex for the affected run. Metal duct repair in Roswell typically runs $320-$560.
Air Leak Repair
Air leak repair is diagnostic work first. We pressurize the system and use smoke pencils or thermal imaging to find the leaks that matter, not every pinhole. In Roswell’s large homes, the most expensive leaks are usually at the plenum or at trunk-line takeoffs where multiple duct runs converge.
Air leak repair runs $260-$480 for targeted sealing of major loss points. If the leak is at a failed plenum connection on a multi-zone system, repair can reach $540-$720.
Duct Insulation
We add or replace duct insulation only where it solves a specific problem: condensation on cool supply lines in humid attics, or heat gain that defeats the AC’s capacity on long runs to second-floor zones. In Roswell, this matters most on north-facing duct runs over the garage or in the lowest-insulated corners of a 1980s attic.
Duct insulation work runs $180-$340 per run, or $480-$760 for full attic re-insulation of a multi-zone system.

Common Duct Repair & Sealing Problems We See in Roswell Homes
- Sagged and separated flex duct in Martins Landing and river-corridor neighborhoods. Original 1970s-80s flex duct has sagged at mid-span and separated at supply-boot collars, drawing humid Chattahoochee-area attic air straight into the supply stream. The camera usually shows a 2-4 inch gap at the collar, with debris buildup downstream from years of reverse infiltration.
- Shared dryer vent stacks in Roswell condos and apartments. The clog forms in the common riser, not at the unit’s lint trap. Most single-unit cleanings miss it. We access the stack from the roof or maintenance chase and run rotary brushes with vacuum extraction through the full length.
- Mastic failure at joints on multi-zone systems in large 3,000+ sq ft homes. Georgia attic temperatures over 140°F break down flex-duct inner liners and loosen mastic at joints. The homeowner notices the second floor won’t cool, or the system runs continuously without reaching setpoint.
- Mold and pollen loading in ducts near the Chattahoochee River corridor. Roswell’s dense oak and pine canopy, which earns it Tree City recognition, drives extreme spring pollen counts. Combined with high humidity from the riparian forest, this creates persistent mold spore pressure on any duct system with even minor condensation leaks.

FAQs - Duct Repair & Sealing in Roswell
Roswell’s residential development peaked between the late 1970s and mid-1990s, filling the city with large colonial and traditional-style homes whose extensive flexible ductwork runs in blistering attic spaces are now 30-45 years old. That aging flex duct, combined with Roswell’s position along the Chattahoochee River corridor and one of metro Atlanta’s densest certified tree canopies, creates an unusually heavy year-round load of pollen, mold spores, and humidity infiltrating duct systems. Cleaning removes debris, but it doesn’t fix separated collars or shredded inner liners that actively draw attic air into the supply stream. Call (470) 495-9370 and we’ll show you what the camera sees.
Yes. We access shared dryer vent stacks from the roof or maintenance chase and run rotary brushes with vacuum extraction through the full common riser as part of our Roswell Dryer Vent Cleaning service. The clog forms in the shared riser, not at your unit’s lint trap, which is why most single-unit cleanings fail to solve the actual problem. We coordinate with building management for roof access and schedule during maintenance windows when required. Call (470) 495-9370 to discuss your building’s access arrangement.
We coordinate directly with your building’s management or HOA to reserve loading-zone access or a service elevator window. Our Nikro portable extractors and Rotobrush systems fit through standard doorways and elevators. We carry proof of insurance and background-check documentation for any building that requires vendor registration. Call (470) 495-9370 and we’ll handle the logistics with your property manager before the appointment.
Roswell sits along the Chattahoochee River in the Georgia Piedmont, where the riparian forest and high relative humidity near the water create persistent mold spore pressure on any duct system with even minor condensation leaks. North Georgia’s extreme spring pollen season, driven by the dense oak and pine canopy that defines Roswell’s neighborhoods, deposits heavy particulate loads inside ductwork. This combination is less acute in flatter, less wooded neighboring suburbs. The result: Roswell ducts fail from humidity and pollen loading at rates we don’t see in comparable-age housing in Alpharetta or Milton. Call (470) 495-9370 for a camera inspection that shows your specific conditions.
Yes. Our repair and sealing protocols align with NADCA ACR standards for assessment, cleaning, and restoration of HVAC systems. We document every duct run with before-and-after photos, maintain negative-pressure containment during agitation, and verify seal integrity with pressure testing where applicable. The H.A.V.E.N. Standard incorporates these protocols and adds our own requirements: Haven Standard Clause 1 for written upfront pricing, Clause 3 for verified crews, and the 365-Day Done Right Promise that applies in writing to every Roswell job. Call (470) 495-9370 for a free estimate.
